Does 60Hz vs 120Hz really matter?

A lot of console games are limited to 30FPS or 60FPS, so the difference between 60Hz and 120Hz won't be noticeable when it comes to motion clarity. However, you do get a lower input lag at high refresh rates, which is great for competitive gaming.

Does refresh rate really matter?

Generally speaking, the higher a monitor's refresh rate, the more FPS your CPU and GPU will need to supply, and the more benefit you'll receive from higher performance options. With that in mind, games vary in how much load they put on the CPU and GPU.

Do you really need 120Hz for gaming?

Do You Need Super-Fast Refresh Rates and VRR for Video Games? Although 120Hz refresh rates on most midrange and high-end TVs work well, don't expect to see any real performance improvement from refresh rates of 240Hz and above.

Which HDMI port is best for gaming on TV?

HDMI 2.1 represents a huge leap over HDMI 2.0, with 48Gbps in bandwidth compared to 18Gbps. Also, HDMI 2.1 introduced standardized variable refresh rate (VRR) support, auto low latency mode (ALLM) to ensure the lowest possible input lag in gaming, and eARC (enhanced audio return channel).

What does ARC mean on a HDMI port?

HDMI Audio Return Channel (ARC) is a particularly useful feature that was added to the HDMI 1.4 standard in 2009. ARC is an additional audio connection intended to replace external cables between the TV and the A/V receiver, or active speaker system, to simplify setup.
