I have a TCL 55 inch 4k smart tv (55s401 series) and there is a massive input lag from my computer to tv. I've put it into gaming mode but that only changed it's slightly, I've also turned off features and nothing really helps.
I have checked my graphics card on my computer and it does support 4k output, HDMI cord is good at least to my knowledge. My question is if you've experienced this problem how did you end up fixing it or if anyone has any knowledge of how to fix it please let me know I've tried everything I could think of.
Sorry if this is an incorrect place to post this, if this is incorrect maybe someone can point me in the right direction?
