So I'm shopping around looking for the best TV to pair with my PS4 Pro. Don't need a ton of screen size but looking for something that will take full advantage. I've heard that OLED makes a big difference with colors even compared to other HDR and 4k sets. The 4k and HDR are essential since that's what I'm getting the Pro to see. The OLED I'm willing to be convinced either way whether it's worth the extra bucks. I mean there's a 43" Sony that has HDR10 but no OLED then there's a 55" LG that is OLED but is about $1,000 more expensive. Have you guys put a lot of research into this or seen them side by side? What TV would you recommend for getting the most out of a PS4 Pro?
EDIT: Also guys I forgot to mention that input lag is NOT a concern! I have never noticed and don't play competitively online so not an issue to consider for me when selecting TVs. I'm also getting it a lot for movie viewing
I know this may sound strange but if you are more seriously into games then a 4K monitor may be the better and cheaper solution since a 27" to 32" one may be the best fit for you. Obviously look at all the features that you require such as HDR10 (PS4pro) and at least one or more HDMI ports. An optical out may also be of use to connect to an external amplifier (assuming optical in) since TV and monitor speakers are normally just barebones although the PS4pro (also the original PS4) does have one as well.
Oh and latency does matter when using HDR even if you are playing single-player games.
Having at least one HDMI port also will allow you to switch between your PC and PS4pro easily although be careful two HDMI ports will work fine but some PC video ports may drop signal . I actually do this with my Desktop PC (HDMI) and PS4 (HDMI) and I can toggle within seconds.
If you want a 4K TV for your lounge I strongly suggest 60" or above (the bigger the better within reason and of course your budget). I have a 55" HDTV and it is great in my lounge but if I decide to eventually get a UHD TV I would be looking at 70" upwards.
One of the main reasons for suggesting a monitor is depending on the members of your household. If you are the only one then no problems but with two or more members you will invariably have conflicts between gaming, watching TV and even playing movies. Also keep in mind that the PS4/PS4pro are fairly small and portable and can be quickly be moved when required since the power and HDMI (2.0a) cables are industry standard and are very cheap so you can cheaply get another one.
When choosing screens do you want flat or curved? If you choose curved you will be able to sit closer but you may find this disorienting so obviously check. I would also recommend checking (minimum 30 minutes) if you are considering the PS Virtual Reality headset (try cinema mode as well) or any VR device.
There are plenty of good technical sites that can give better advice and not all of them are technical to the point where you need an engineering degree to understand. However, it does help to be more technically aware when choosing 4K TV's or monitors because there is allot of hype out there.
