A 38-inch curved screen is the size where one panel finally replaces the two monitors crowding your desk. The catch: this size is sold in two different shapes. Most picks here are ultrawide 21:9 panels that keep two full documents side by side with no middle bezel. A few are standard 16:9 4K screens that trade that extra width for a taller, TV-like picture. Some listings also land just shy of 38 inches — a 37.5-inch model is the same class of screen and behaves identically on a desk. This guide sorts every pick by what it is actually good at, so you end up with the one that matches your work, not the one with the loudest spec sheet.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Prices swing hard at this size, but the split that matters is simpler: work-first panels versus gaming-first panels. The details that decide it — resolution, curve radius, and USB-C power — are what separate a good 38-inch curved monitor from an expensive one you fight daily.
Our Picks at a Glance
How To Choose The Best 38-Inch Curved Monitor
At this size, a monitor stops being a peripheral and starts being furniture you look at for eight hours. Three choices decide whether you love it: the shape of the screen, the sharpness of the panel, and how many cables you are willing to live with.
Ultrawide or standard widescreen?
An ultrawide has a 21:9 aspect ratio, which means the screen is much wider than it is tall. That extra width is what lets you park a spreadsheet, a browser, and a chat window next to each other without overlap. A 16:9 screen is the same shape as a television — less horizontal room, but a taller picture that suits console gaming and video without letterbox bars. If you live in documents and dashboards, ultrawide wins. If you mostly play games or watch video, the standard shape is easier to live with.
Why 1600 vertical pixels matter
The vertical pixel count is the number that decides how much scrolling you do. A 3840 x 1600 panel gives you 1600 pixels of height, which is more than a 1440p screen and close to what a 4K panel offers vertically. In practice that means one more paragraph, one more code block, or one more row of a table visible before you touch the scroll wheel.
Panel type: IPS, VA, or OLED
IPS panels hold their color and brightness when you view them from an angle, which matters on a wide screen because the edges sit off to your sides. VA panels push deeper blacks and higher contrast, so dark scenes look richer. OLED turns individual pixels on and off, which is how it produces true black — the trade-off is that OLED demands a little care in daily use.
Curve, USB-C, and KVM
The curve number tells you how aggressively the screen wraps toward you. A gentler radius keeps straight lines looking straight, which professional work depends on. USB-C with power delivery lets one cable carry video, data, and laptop charging at once. A built-in KVM switch lets one keyboard and mouse control two computers, so you can hop between a work laptop and a desktop without reaching for a second set of peripherals.

In‑Depth Reviews
1. Dell U-Series 38″ 4K UHD 1600p Ultra Wide Screen LED-Lit Monitor (U3818DW)
Our pick — 4.5★ from 700+ verified ratings; the strongest balance of quality and price.
The dual-monitor killer that fills 1600 vertical pixels without a seam down the middle.
You get two full windows side by side with no plastic divider between them, thanks to a 3840 x 1600 resolution across a 21:9 screen (the ultrawide shape). Owners who came from two-screen setups describe the switch as immediate. Six devices can connect at once through Bluetooth 4.0 and RF (radio frequency), and one USB-C cable carries video, audio, and data between your laptop and the monitor. Its 99% color gamut coverage leads this list, well ahead of the Samsung Odyssey G7’s 0.99, so it wins on color fidelity.
Where it earns its keep is the desk itself. The 1600 vertical pixels mean you scroll less, and the 1000:1 contrast ratio keeps text crisp for coding and spreadsheets. The KVM feature lets one keyboard and mouse drive two machines. What wins people over most is the display quality itself, followed closely by picture quality — panel clarity is the thing this model is bought for.
Here is the honest catch, and it is a real one for Mac owners. Reported compatibility is mixed on macOS, with users flagging that USB-C lacks the bandwidth to push full resolution and USB 3.0 at the same time, and that macOS volume control does not work through the monitor. Its brightness sits in a mixed zone too. Neither issue touches Windows or Linux, where this thing just works. The other quiet detail: this is a 60Hz-class work panel, so competitive gamers should look further down this list.
What Holders Rave About
- Display quality is the runaway strength, with picture quality the obvious second — this is a buy-it-for-the-panel monitor
- 3840 x 1600 keeps two documents side by side and cuts daily scrolling
- USB-C single-cable setup plus KVM for a two-computer desk
- Six-device connectivity over Bluetooth 4.0 and RF
Where It Asks For Patience
- Mac compatibility is mixed — bandwidth limits and no macOS volume control
- Brightness lands in a mixed zone rather than dazzling
- Only two USB-in ports for peripherals
Settle in here if: you run Windows or Linux, want one screen to erase a two-monitor setup, and care more about accurate color than refresh rate.
Keep browsing if: you are on a Mac and expect flawless USB-C behavior, or you want high-refresh gaming.
2. Gawfolk 37.5 Inch Gaming Curved Monitor 3840×1600p 144Hz PC Monitor
Ultrawide frame, 144Hz speed, entry-level price — the gaming value play of this list.
The number that sells this one is the refresh rate: 144Hz on a 3840 x 1600 ultrawide. That is a faster panel than the Dell U3821DW runs, and it sits on the ultrawide 21:9 shape rather than the Odyssey G7’s 16:9. The 21:9 format gives you more horizontal room than the Samsung’s widescreen layout, which is the difference between two documents side by side and one wide one.
Serious players get the gaming kit they check for: G-Sync and FreeSync support sync the panel with your graphics card to cut tearing, plus MPRT (a motion-blur reduction technique) and a black equalizer that brightens dark corners without washing out the rest of the picture. Two HDMI 2.0 and two DisplayPort inputs let you keep a PC and a console plugged in at once. The panel hits 350 nits of brightness and uses 8-bit plus frame rate control to reach 10-bit color, producing 1.07 billion colors for smooth gradients.
Read this part carefully. Reviews on this one run hot and cold — some units arrive flawless, others show dead pixels or loose internal screws, and one owner traced a red glow back to the on-screen crosshair feature rather than a faulty pixel. A few buyers also found the curve uncomfortable at close range. Treat it as a value gamble: great when it lands right, so buy where returns are easy.
Where the money goes: 144Hz, 3840 x 1600, G-Sync and FreeSync, and dual DisplayPort on an entry-level budget — the speed-per-dollar math here is hard to match.
The roll of the dice: quality control is inconsistent across units, and the fixed ambient backlight cannot be customized beyond its presets.
Made for: a budget gamer who wants a fast ultrawide and can accept that the panel lottery may run against them.
Not the one for: anyone who needs out-of-the-box consistency or professional color accuracy — the panel is specified for 80 color gamut versus the Dell U3818DW’s 99.
3. Samsung 37” Odyssey G7 (G75F) Series 4K UHD Curved Gaming Monitor
Over four square feet of curved 4K, wrapped around your field of view.
This panel makes the biggest impression the moment you unbox it. It runs 3840 x 2160 at 165Hz (refresh rate, or how many times per second the screen redraws) with a 1ms response, wrapped in a 1000R curve — the tightest radius on this list, pulling the screen around your head rather than sitting flat in front of it. Its 3000:1 contrast ratio is the strongest of any non-OLED pick here, three times the Dell U3818DW’s 1000:1, so dark game scenes look genuinely deep instead of washed grey.
Console owners get the most from it. PS5 users describe crisp 4K at 120Hz, and the sheer size helps anyone straining to read small subtitles. The 16:9 shape also means no black bars for video or console output — something the ultrawide picks cannot offer. Display quality leads what owners praise, with picture quality a clear second.
The catch is the curve itself. At 1000R it is aggressive, and the distortion across straight lines is visible in everyday work — windows and text bow slightly, which is fine for gaming and active media but distracting for spreadsheets. A few buyers also note uneven backlight bleed in dark scenes and a heavy stand. None of it stops the panel from being a standout for play; it just means this is a gaming-first screen that happens to be usable for work, not the reverse.
what separates it
- 3840 x 2160 at 165Hz with a 1ms response — as fast as it is sharp
- 3000:1 contrast for genuinely deep blacks, the deepest of the non-OLED picks
- 16:9 shape means no letterboxing for console and video content
- 1000R curve pulls the picture into your peripheral vision
What To Know Before Buying
- The aggressive curve distorts straight lines and small text in productivity work
- Backlight unevenness shows in very dark scenes
- It is a heavy panel that dominates a desktop
Buy it for: console and single-player gaming where a huge, bright, deep-black 4K picture is the point.
Think twice if: your monitor is a work tool first — the curve will not sit flat for spreadsheets and text editing.
4. LG 37G800A-B 37-Inch UltraGear 4K UHD (3840 x 2160) Curved Gaming Monitor
A 4K curved panel that plays as hard as it works, with USB-C docking built in.
What separates this from the Samsung pick above is the docking story. It runs the same 3840 x 2160 at 165Hz with a 1ms response, but it adds USB Type-C with 65W power delivery, so a single cable can carry your laptop’s video, data, and charge at once. Two HDMI 2.1 ports, DisplayPort 1.4, and two downstream USB ports round out a genuinely serious connection set for a monitor at this price.
Its 4000:1 specified contrast edges out the Samsung Odyssey G7’s 3000:1 and far exceeds the Dell U3821DW’s 1000:1. Its 400 nits is the brightest of the panels listed here, and it covers up to 95% of the DCI-P3 color space video editors care about. Gaming aids are thorough — Dynamic Action Sync to cut input lag, Black Stabilizer to lift dark scenes, and a crosshair overlay for shooters. Owners describe it as rich for eight-hour work days and easy for gaming, with the curve fading into the background once you adjust.
The honest note here is a weight-and-size one. At roughly 32 inches wide and 25 inches tall it dominates a desk, and more than one owner flags it as heavy enough that a monitor arm is a risk rather than an upgrade. There is also a mixed reliability thread, including a report of a USB-C port that would not deliver power. Treat the panel as a strong performer and handle the mounting decision with care.
Verdict on the hardware: 4K at 165Hz, 4000:1 contrast, 400 nits, and USB-C with 65W delivery — one cable covers a gaming PC and a work laptop.
The size reality: this is a heavy, full-depth panel; plan desk space and skip the lightweight arm mount.
The pick for: a gamer who also docks a laptop and wants one clean cable doing all the work.
Look elsewhere if: you need a light panel on an arm, or you want the flat 21:9 ultrawide shape.
5. Deco Gear 40 inch Curved 5K2K Ultrawide Monitor, 5120×2160 WDQHD 21:9 IPS
The resolution monster: 5K2K across 40 inches for anyone who reads data for a living.
Sharpness is the whole reason to look here. This panel pushes 5120 x 2160 across a 40-inch 21:9 screen — that is more horizontal pixels than any other pick on this list, and it comes with the ultrawide width that leaves the Samsung’s 16:9 layout behind. The IPS panel holds its color and contrast across 178° viewing angles, and it covers 100% sRGB, 95% NTSC, and 96% DCI-P3, so photo and video work stays true from edge to edge.
Developers and analysts get their money back through desktop utility. A single USB-C cable carries video, data, and up to 90W of laptop charging, and the built-in KVM (a switch that lets one keyboard and mouse control two computers) plus PIP and PBP (picture-in-picture and picture-by-picture) let you run two inputs at once — a work laptop and a desktop sharing one keyboard, one mouse, and one screen. Screen quality leads what owners praise, with picture quality a strong second.
Be clear-eyed about the trade-offs. The 75Hz refresh rate and 300 nits of brightness put this firmly in work-panel territory, not gaming-panel. There is also a real reliability thread here: some units have arrived with loose or fallen screws, and a handful of buyers report USB-C port failures over time with slow support follow-up. Buy from a seller with a straightforward return policy, and this panel delivers a huge amount of desk real estate for the money.
Why It Earns Its Place
- 5120 x 2160 across 40 inches — the most pixels here
- IPS color at 100% sRGB and 96% DCI-P3
- USB-C 90W power delivery plus KVM and PIP/PBP
- Height, tilt, and swivel adjustment on the stand
The Fine Print
- 75Hz and 300 nits — not built for competitive gaming
- Some units ship with loose screws or develop USB-C faults over time
- Support follow-up can lag on the rare problem unit
Best matched to: developers, analysts, and traders who want maximum pixels and a one-cable dock, and can buy with easy returns.
Skip this one if: you are buying primarily to game at high refresh, or you need bulletproof out-of-box reliability above all else.
6. LG UltraGear 39GX900A-B 39” OLED Curved WQHD Gaming Monitor
The OLED that brings true black and 240Hz speed to a 39-inch ultrawide.
Two numbers carry this panel: 240Hz and a 0.03ms response time, delivered on an OLED screen (organic light-emitting diode, where each pixel makes its own light) with a 1.5 million to 1 contrast ratio. That 1.5M:1 figure is on a different plane from every other pick here — where the Samsung Odyssey G7 manages 3000:1, this OLED produces true black because individual pixels switch fully off. FreeSync Premium and G-SYNC compatibility keep frames in lockstep with your GPU across PC and consoles.
It is not only a gaming panel. The 21:9 ultrawide shape and 3440 x 1440 resolution are excellent for spreadsheets and multitasking, and the anti-glare OLED surface keeps reflections from cutting into focus. The 800R curve wraps the screen close, with one owner saying the added width makes a big difference — that is the rich effect ultrawide is meant to deliver, and this is the most rich pick here.
The care note is real, if manageable. OLED panels want periodic pixel cleaning, and reviewers consistently run a cleanup cycle right from the start and then on occasion — it is routine maintenance, not a fault. There is also a mixed reliability thread, with a small number of owners reporting the panel switching off unexpectedly. Treat the maintenance cycle as part of ownership and the picture quality as the payoff.
The headline: 240Hz, 0.03ms, and 1.5M:1 true-black OLED contrast — the fastest and deepest panel here by a wide margin.
Routine to expect: run an OLED cleanup cycle at unboxing and every so often, and be aware a handful of owners hit occasional power-off quirks.
This is your pick if: picture quality and speed both matter and you want the fastest panel on this list.
Look toward the VA options if: you would rather not deal with OLED maintenance or accept occasional reliability quirks.
7. Dell U3821DW UltraSharp Curved USB-C Hub Monitor – 37.52-inch WQHD
The monitor that quietly replaces the docking station bolted to your desk.
Pick this over the Dell U3818DW at the top of the list for the hub. It carries 3840 x 1600 across a 37.5-inch 21:9 curve, but adds RJ-45 Ethernet (a wired network port), USB-C with up to 90W of laptop charging, MAC Address pass-through, PXE Boot, and Wake-on-LAN — the networking features remote workers and office setups actually need. Its 2300R curve is gentler than the Samsung Odyssey G7’s 1000R, which is the right call for a work panel where straight lines matter. The display covers 100% sRGB, 100% Rec 709, and 95% DCI-P3, so charts and video content render true.
In daily use, this is a desk-clearing tool. The Auto KVM detects which PC was plugged in last and switches your keyboard and mouse to it, and two 9W speakers carry meetings without a separate set of desk speakers. Owners who moved from two-monitor setups describe plugging in a single cord and getting both screen real estate and laptop charging at once. The front hidden ports make it easy to charge a phone without reaching around the back.
The trade-off is straightforward: this is a 60Hz panel and it is priced like a premium one. If you game competitively, the Gawfolk or either LG above will beat it on speed. And there is an anecdotal report of a unit arriving with a cracked screen — an occasional shipping outcome, not a design flaw. For software developers and office work, though, that extra connectivity is worth far more than refresh rate.
Where It Delivers
- 3840 x 1600 at 37.5 inches with a gentle 2300R curve
- USB-C 90W plus RJ-45 Ethernet and remote-management features
- Auto KVM switches between two PCs on one keyboard and mouse
- Dual 9W speakers replace a separate set
What You Trade Away
- 60Hz refresh rate — not aimed at gaming
- Premium-tier positioning for a work-first panel
- Occasional shipping damage reported on arrival
Reach for this if: you dock a work laptop daily and want one cable, one screen, and wired networking handled.
Keep looking if: high refresh gaming is a priority, or you want the top pick’s slightly sharper color.
8. ViewSonic VP3881A 38 Inch WQHD+ ColorPro Curved Monitor
A color-first 38-inch curve built for photo and video editors who cannot guess at hues.
Color accuracy is the entire reason this panel exists. It carries 3840 x 1600 across the 21:9 ultrawide shape, with 100% sRGB and Rec 709 coverage and Pantone validation — the certification professional designers look for when they need colors to match between screen and print. It ships with hardware calibration support, plus sRGB, Rec 709, and Adobe RGB modes for switching color spaces without third-party tools. For editors cutting video or retouching photos, that is the headline feature, and it earns its place next to the pixel-heavy Deco Gear for creative work.
The ergonomics and connections are built for long sessions. The stand offers tilt, height, and swivel adjustment, the antiglare screen cuts reflections, and there is a blue light filter for reducing strain. Flexible inputs cover USB-C, HDMI, DisplayPort, and Ethernet, and rear USB ports let you run a camera, headset, and other peripherals through the display. Independent reviewers describe it as an excellent upgrade for photo and video editing with no tearing, flickering, or dimming.
Now the honest part: this is the priciest pick here, and it does not pretend to be a gaming panel. Refresh rate is low, and the base is physically large, taking up desk depth. A few owners also flag that the rear buttons sit close to the power switch, so accidental shutoffs happen. For a color-critical workstation, none of that is disqualifying — but you are paying a premium for accuracy over speed, and you should know that going in.
What Makes It Sing
- 100% sRGB and Rec 709 with Pantone validation for color-critical work
- 3840 x 1600 across 21:9 — plenty of real estate for editing and multitasking
- Hardware calibration support plus sRGB, Rec 709, and Adobe RGB modes
- Full ergonomic adjustability and a blue light filter
What To Weigh
- Low refresh rate — not a gaming panel
- Physically large base takes desk depth
- Rear buttons sit near the power switch, risking accidental shutoff
For the colorist: photographers, video editors, and designers who need Pantone-validated accuracy and hands-on calibration.
Not for the twitch player: if quick refresh and high frames per second win your day, the LG OLED or Samsung 165Hz panels beat this one.
Understanding the Specs
Resolution (3840 x 1600 vs 5120 x 2160)
Resolution is the number of pixels across and down. Ultrawide 38-inch panels mostly run 3840 x 1600, which is a touch short of 4K in height but wider than a standard 4K screen. A higher-resolution panel like the Deco Gear’s 5120 x 2160 packs more pixels across, which keeps text and details sharper on a big screen. If you read dense tables or edit 4K video, extra pixels help. If you mostly game and browse, 3840 x 1600 is plenty.
Curve Radius (2300R, 1000R, 800R)
The R number measures how tightly the screen curves — a lower number means a tighter wrap. A 2300R curve is gentle and keeps straight lines looking straight, which professional work relies on. A 1000R or 800R curve wraps the picture around your view for a more rich feel but bends small text at the edges. There is no universal best here: tighter curves suit gaming and media, gentler ones suit spreadsheets and design.
Panel Type (IPS, VA, OLED)
IPS holds its color and contrast from wide angles — useful when the edges of a big screen sit off to your sides. VA pushes deeper blacks and higher contrast, which dark games and movies benefit from. OLED switches individual pixels fully off, which is how it delivers true black and near-instant response. IPS and VA cost less and need less maintenance; OLED looks the best and asks for periodic pixel care.
USB-C Power Delivery and KVM
USB-C with power delivery means one cable can send video, data, and charge back to your laptop — the Dell U3821DW, Deco Gear, LG UltraGear 37, and ViewSonic all offer this. KVM (Keyboard, Video, Mouse) lets a single keyboard and mouse control two computers, so you can switch between a work laptop and a desktop without moving cables. Both features matter most if you dock a laptop daily.
