GAMERS BEWARE
If you’re a serious gamer who already has or plans to get an Xbox Series X, PS5 or a highend AMD or NVidia PC graphics card, you need to be particularly careful about which TV you buy. The best features of these new gaming devices place some pretty extreme technical demands on the displays they connected to. Delivering 4K resolution at 120 frames a second and variable refresh rates, in particular, require TVs to carry the latest HDMI 2.1 connectors capable of handling data rates of 40Gbps or higher. Practically no budget TVs can provide even a single sufficiently specced HDMI 2.1 port to unlock these next-gen gaming features. But nor, actually, do many mid-range TVs. And even mid-range and high-end TVs that do support 4K/120 and VRR often only do so over one or two of their HDMI connections, not all of them. Which could mean having to switch HDMIs over if you have more next-gen gaming devices than your TV has next-gen HDMI ports. Unfortunately, making sure a TV definitely supports the gaming features you want is complicated by the fact that TV brands are unhelpfully allowed to say they have HDMI 2.1 ports even if they don’t. Instead you need to check specifically that a TV’s features include 4K/120 and VRR support.
This seems fair enough – until you realise that TV brands aren’t all great at making it clear exactly which gaming features their TVs support. Some brands – LG in particular – do better than others at supporting cutting edge gaming features. But ultimately this is something you’ll need to either look to reliable product reviews to tell you about, or else obtain a sufficiently trustworthy/official answer (sadly, this may not include the advice of customer service agents) before you part with your cash.
