Small TVs that are not specially designed for gaming have a high latency, i.e. what you do with your controller is displayed on the screen with a delay. This isn't a problem for cosy games, but it ruins the fun for faster or competitive games. The PS5 outputs a maximum of 120Hz at 4K video resolution. Look for something that supports this so that you can use the full potential of your PS5, this monitor can display up to 240fps but "only" in Uhd (2K).

I bought this monitor especially for my PS5. For 2k@120Hz this monitor is the best option for the PS5. Of course, an HDMI 2.1 cable is essential (it's best to buy the one supplied with the PS5 or a suitable one).
Most 2k monitors have 120Hz, but must be controlled via DisplayPort (via PC graphics card). The PS5 absolutely needs a monitor with HDMI2.1 port, so pay close attention when buying.
