So i plugged in my ethernet instead of wifi, as well as making sure the output settings were set at 1080p. I didn't notice any difference in the input lag, however, the overall connection was slightly better. I also tried the output settings at 720p just to see if the game would run smoother, and that didn't help at all. Is there anything I can tweak on the tv / ps4 settings that can reduce this input lag?
Some people on YouTube / other websites are saying that renaming the HDMI input to 'PC' will reduce the input lag. Not sure why, but it's worth a shot. Problem is, I don't know how to do that. Anyone know how to do that? LG TV Model is 32LN53
