I am very curious to know if this is the case. I was thinking of upgrading to 4K myself but HDR will be useless in anything but replays to me if it means increased input lag via HDR post-processing outside of game mode.
Can anyone confirm this is the case? Can you use HDR in game mode on any current tv or is it always post processing and never used in game mode?
Slight digression from your point: I cannot speak for anyone else, sadly, but I have been going through a forum, where people who had PS4 Pro's are having a lot of trouble with their LG TV's not working with PS4 Pro as they should. Even though everyone has HDR, the Playstation is still saying HDR is not supported when looking in the:
Settings
Video Output Settings
Video Output Information menu.
I also have this issue. My TV's HDMI ports all support HDR, it seems, yet my PS4 ( vanilla ) won't acknowledge it.
Going by various forum posts, it turns out that this is actually an LG firmware issue
( my TV is up to date with firmware ) and they are apparently working with Sony on a fix. When or
if that TV firmware update is coming, is anybody's guess
It might also be my HDMI cable, even though I am certain is HDMI 2.0, not 1.4 or whatever the previous standard was...
Back to your point. With my specific TV, if i play any game outside of Game Mode ( let's say Cinema or "Expert1/2" Mode ) the post processing of the images causes a delay of at least half a second or so. It's
really off putting. Making split second decisions in GT Sport would be incredibly handicapped for me. It could be that I could simply spend some time adjusting the many image menus on my TV, turning things on or off, or adjusting sliders to reduce or eradicate the issue altogether perhaps, but I'm not savvy enough to know what effects what.
It might be that my TV is a bit older ( even though it gets firmware updates still ) and that the lag issue is specific to my model. Maybe the hardware itself isn't up to scratch for 4k gaming? I would still highly recommend upgrading to a 4k, simply because the image on these TVs ( mine included ) is absolutely beautiful. Even over a 1080p TV, the leap is significant. I guess that there are many tech forums and sites out there that have lists of TVs, specifically set out to be "best for gaming" suggestions.
I think I asked the question originally, thinking too broadly about TVs in general, when in fact there are so many subtle differences between so many TVs that can make or break a gaming experience, should you want HDR (and 4k if you have the Pro too, of course ).
