1. I bought this converter (can't link it as I don't have 5 posts yet), "Plugable Active Mini DisplayPort to HDMI 2.0 Adapter" from amazon.ca, thinking it was what I want and although it does native 4K UHD resolution @ 60hz just fine it does not do 10 bit colour (HDR) at that resolution/refresh rate as it is only HDMI 2.0 instead of HDMI 2.0a, limiting me to RGB 8bit instead of RGB 10bit, which I later found out. I am in the return grace period and was wondering if there is a different converter I should buy which supports RGB 10 bit colour at full resolution or is it not going to make enough of a difference for me to care? I think I would prefer to just get one which fully supports the tech on the TV but I don't know what to buy. If I turn on the UHD colour option for the HDMI port I am plugging it into I just get a screen saying there is no input.
2. As someone who primarily games on my gaming laptop @ 100hz I prefer to play all of my PC-centric games on my PC and not on the TV, but I play a fair amount of games with my friends on the TV from my PC with wireless xbox controllers. We don't play anything online competitive and I would never in my life touch an FPS with a controller so mostly we play fun four player couch games like Crawl, Helldivers, Duck Game, Gang Beasts, Enter the Gungeon, Sonic Allstars Racing, Redout, Rocket League, Dead or Alive 5 etc... I have seen the differences between the input latency on the 5th HDMI port versus the other four on rtings and is a difference of 30ms really gong to make any difference at all to us or should I just forget about it and keep it on HDMI 2 and switch it to computer mode with game low latency on when we play games?
3. Regarding the resolution of games I have no idea about modern HDTV scaling engines so if I play a game at 1920x1080 or 2560x1440 with game low latency mode on does the TV upscale the picture to 3840 × 2160 regardless of what settings I have on? For now I have a custom resolution set to 2560x1440 for games to get more displayed on the screen than 1080 (which is really noticeable in Helldivers and is awesome) and not hit my GPU as hard as 3840 × 2160 would. On some games, though, I can't notice a difference between 1080 and 1440 so would that be the game keeping everything on the screen the same size no matter the resolution and ALSO the built in scaling engine doing its job? Simply put, is the TV always upscaling everything to 3840 × 2160 no matter the input (1080, 1440)?
4. When is the tablet getting 6.0.1? As it stands now with 5.1.1 and Dec 2016 security patch it is extremely vulnerable and that makes me nervous considering I am logged into my google account with it.
Any and all comments/recommendations are fully welcome!
1. You can't get 10bit RGB, HDMI 2.0 has a bandwidth of 18gbps, and RGB or 4:4:4 chroma would require more bandwidth.
You should be able to select 4:2:2 chroma in 10bits, though.
2. It really depends on how sensitive you are to input lag. I think I would probably notice it, but if you're not playing competitively and you're both playing on the same TV, and it's not FPS, I don't think that the extra lag should be an issue for you.
3. Every set upscales, otherwise any resolution below the native resolution of the panel wouldn't take up the whole screen.
I'm not sure whether 1440p is supported on the P series, though. You won't have a problem with 1080P.
