TVs only allow for low input lag when in Game Mode.If not, check to see if there are any HDR settings or contact customer support. Note: TVs should usually automatically switch into HDR when content is played. If it's set to the lower bandwidth settings, like HDMI 1.4, the TV may think you don't want HDR content to be played. If it doesn't, it will usually end up playing in the basic HDR10 format instead. LG and Sony TVs don't support HDR10+, while Samsung doesn't support Dolby Vision. Check to see if the TV supports the format your content is in.However, not all TVs do this, and they don't specify which HDR format is playing, like on Samsung TVs. You may see Dolby Vision or HDR10+ logos from streaming apps appear when you first play the content. You should always enable the necessary bandwidth because even setting it higher than needed can cause compatibility issues. This represents the TV's bandwidth an HDMI 2.1 source won't display properly if you set the TV to '1.4', as you'll be limited in the resolution and frame rate.

TVs will have settings for 'HDMI Mode', or something similar, where you can choose between '1.4', '2.0', or '2.1', or have other settings called 'Full Color' on Vizio and 'HDMI Ultra Deep Color' on LG. Enable the highest bandwidth setting on the TV.Verify that the input is put in properly.For starters, make sure the input on the TV is set to the input your device is plugged into.

Once you fix it, there's no need to do anything else. If that doesn't fix anything, find your related issue below. Check your HDMI connections, and if possible, unplug and plug them in again. Of course, the first step to any technology-related problem is to check if all components are properly plugged in.
