Nothing wrong with TN for those who want fast response times and high refresh rates, well beyond what anyone can "Feel" or react to, or do not care about 100% colour accuracy etc or a having a space heater in front of them.
I have a 50" LG Nano 4k 120hz HDR TV and whilst it looks great playing games and honestly I am looking forward to actually getting a LG C2 now, this thing doesn't half get hot so hot in fact that I cannot touch the frame of the TV for 30 minutes without feeling like I am going to burn myself.
Apparently the OLED screens are just as bad if not worse because they get brighter etc.
If it was not for wanting HDR in my monitor/tv, I would go TN again for the high refresh rates and the fact I don't do "Colour Accurate" photo/video editing so the expense of a IPS or other type display is not really required for me.
