Many of the best TVs include HDMI 2.1 ports, but this feature is less common on smaller screen sizes. However, several of our best 50-inch TV picks — the LG C5, Samsung QN90F, and Vizio MQX — do include HDMI 2.1 support, which is useful for gaming enthusiasts. 

HDMI 2.1 connections can transmit signals at 4K/120Hz, along with variable refresh rate (VRR) and auto low latency mode (ALLM), when paired with a compatible gaming device, such as a PS5 or PC. These features provide a smooth gaming experience with fast motion, minimal lag, and reduced screen tearing. You can learn more in our guide to the best gaming TVs.

To enable HDMI 2.1 features, all of your home entertainment components must have HDMI 2.1 ports. So if you're hooking up a PS5 to a soundbar connected to your TV, all three devices must support HDMI 2.1. You also need to use ultra-high-speed HDMI cables rated for 48Gbps to pair everything together. Visit our guide to the best HDMI cables for recommendations and more details. 

The best 50-inch TVs are ideal for buyers who require a compact display that fits in a smaller room and accommodates a smaller TV stand. However, there are fewer midrange and high-end TVs offered in this size compared to what you'd find when shopping for a larger display.

For instance, many of the best OLED TVs are only available in 55, 65, and 77 inches. Likewise, several of our favorite QLED TVs from brands like TCL, Hisense, and Roku, like the QM8K, U8QG, and Roku Pro Series, are not available in a 50-inch size. 

That said, there are a few exceptions, such as our top pick in this guide, the LG C5, one of the few OLED TVs available in smaller sizes. But generally speaking, most 50-inch TVs are built with entry-level and lower midrange performance in mind.

Although the benefits of 4K resolution are best appreciated on larger TV sets, a 50-inch display is still substantial enough to make 4K worthwhile, especially if you plan to sit close to it. 

However, the debate about whether 4K is worth it on a TV this size has become a moot point since major brands no longer sell 50-inch HDTVs. Most HDTV models are now restricted to 43 inches and under. If you're buying a 50-inch or larger TV in 2026, 4K is the standard.
