With next-gen consoles on the way, and PS5 preorders coming and going like hotcakes, one question you might be asking yourself after securing your PS5 or Xbox Series X preorder is whether you need to shell out for a new TV. The PS5 and Xbox Series X both support 4K and 120Hz. There aren't many TVs that feature both a 4K resolution and 120Hz refresh rate, and if you're reading this article, yours likely doesn't either.

The simple answer is that a 120Hz-capable TV is not required, but there are some noticeable benefits. Here's what you need to know about upgrading your TV for next-gen and the best TVs to buy for the PS5 and Xbox Series X.

What's HDMI 2.1?

If you want a 4K resolution with 120Hz refresh rate and HDR, you're going to need a TV with an HDMI 2.1 port. This ensures that your TV can accept the speeds afforded by HDMI 2.1 cables--48Gbps--which are what the PS5 and Xbox Series X utilize to transfer video and audio signals to your television. HDMI 2.1 is still relatively new to consumer displays, with only a select few TVs supporting it and no PC monitors currently available on the market that support it--though Asus has announced HDMI 2.1 monitors that should release in the near future.
