Small 4K TV for Gaming | Best 42-43 Inch Picks

The best small TV for gaming is a 42-inch OLED with 4K resolution, 120Hz native refresh, and four HDMI 2.1 inputs.

Small 4K TVs for gaming usually land at 42 to 43 inches, and while a handful of brands compete there, two names stand apart: LG and Samsung. Each takes a different approach, and that difference decides which one fits your console or PC setup. Here’s the honest breakdown of the best small 4K gaming TVs and the specs that actually matter.

What Makes a Small TV Suited for Gaming?

A 4K label alone doesn’t make a TV good for gaming. The three specs that matter most are native refresh rate, HDMI ports, and response time. A TV can be 4K but still stumble with motion blur or capped framerates if the inputs can’t carry the signal.

For modern consoles, you want at least a 120Hz native panel and HDMI 2.1 ports. HDMI 2.1 carries 4K at 120Hz without compression, which is exactly what the PlayStation 5 and Xbox Series X can output.

LG’s 42-inch OLED evo C4 (model OLED42C4AUA) spec pages list 3840 x 2160 resolution, a 120Hz native refresh rate, and four HDMI 2.1 inputs across four total HDMI ports. That combination is rare at this screen size.

LG 42-inch OLED evo C4 vs Samsung 43-inch QLED: Which Leads?

The LG C4 is the strongest small-size gaming pick because it delivers OLED contrast and gaming features without compromise. Samsung’s 43-inch lineup covers a wider price range, with some models better for budget buyers and one specifically pitched at gamers.

Samsung’s US 43-inch page states 43-inch class TVs come in either 4K UHD (3840 x 2160) or 1080p FHD (1920 x 1080), so double-check the resolution before buying. The same page calls the 43-inch QN90 Neo QLED the “optimal choice for gaming,” citing 4K resolution and Game Mode. For a bright living room where OLED glare is a concern, the QN90 is the safer bet.

If you’re comparing specific models side by side, our tested roundup of the best small 4K TVs ranked for gaming breaks down the top performers by price and features.

HDMI Port Limits and Refresh Rate Caveats

Not every port on a small 4K TV carries the same gaming signal. That means a 120Hz signal might not reach a high-refresh display on every input.

Verify the port layout before you buy. LG’s C4 lists HDMI 2.1 on all four inputs, but Samsung’s budget models may reserve full bandwidth for one port. The fix is simple: plug the console into the labeled input and read the manual’s port chart.

Refresh rate branding also confuses buyers. LG’s C4 specs list a 120Hz native refresh rate, while Samsung’s Q7F page highlights Motion Xcelerator 144Hz. That’s a marketing feature that enhances motion handling, not a guarantee the panel runs at 144Hz from every source. Match the TV’s real native refresh to what your console outputs, and you’ll avoid the buyer’s remorse.

Gaming Features That Need Fine Print

The LG C4 page includes a gaming requirement note: some features need a 144Hz graphics card and a compatible gaming controller, and one gaming-oriented feature requires a subscription. Nothing about the core 120Hz 4K experience costs extra, but the bells and whistles aren’t all free.

Samsung’s 43-inch QLED page advertises gaming support marked “Yes (Adaptive / Gaming)” and highlights Game Mode as the key setting. Turn on Game Mode to reduce input lag, and enable Adaptive settings if your model supports them for automatic picture tuning.

One more caveat: retailer prices fluctuate. Both are solid values at those prices, but check today’s listings before committing.
