The Dell UltraSharp U4025QW is a 40-inch 5K2K (5120×2160) ultrawide with a 21:9 aspect ratio, but it uses IPS Black technology rather than OLED. While it doesn’t achieve the per-pixel blacks of OLED, its 2000:1 contrast ratio is twice that of standard IPS panels, delivering far better shadow detail for professional color-grading and spreadsheet work. The 120Hz refresh rate and 5ms response time make it usable for light gaming but not competitive esports.

The primary appeal is the built-in KVM hub with Thunderbolt 4, Ethernet, multiple USB, HDMI, and DisplayPort connections, allowing seamless switching between two PCs. The 600-nit brightness provides excellent visibility in bright offices, and the anti-glare coating is effective. The 99% DCI-P3 and 99% sRGB coverage deliver professional-grade color accuracy.

Dell’s premium build includes height, tilt, swivel, and pivot adjustments, along with a compact footprint despite the large screen. Some owners note the plastic chassis feels less premium at this price point than the metal construction of competing professional monitors. The lack of OLED’s infinite contrast is evident in dark room scenes, but in a well-lit office environment, the IPS Black panel is more practical than any OLED.

The Samsung Odyssey Ark 2nd Gen redefines what a monitor can be: a 55-inch 1000R curved display that rotates into Cockpit Mode (vertical orientation) for a completely different gaming perspective. However, it uses Quantum Mini-LED (QLED) rather than OLED, so it lacks the per-pixel black levels of true OLED. The 4K resolution at 165Hz with a 1ms response time is respectable, but the mini-LED backlight has local dimming zones (rather than infinite contrast) that can still produce blooming in extreme scenes.

The 4-Input Multi View system can display up to four sources simultaneously on a single screen, including consoles, PCs, and built-in apps. The 60W 2.2.2-channel speaker system with Dolby Atmos delivers immersive audio with 45Hz bass extension, eliminating the need for a separate soundbar. The Neural Quantum Processor Ultra upscales lower-resolution content to 4K quality via 20 neural networks.

The sheer weight (~100 lbs) and assembly complexity mean this is a permanent fixture, not something you rearrange. Connectivity includes one DisplayPort, multiple HDMI 2.1 ports, and a USB hub. Some owners report One Connect Box reliability issues and Samsung’s warranty support as inconsistent. For users who can manage the size and weight, the immersive experience is unmatched by any other monitor, but it is not a pure OLED.
