I don’t think the ps4 pro is actually playing games in 4K.
The new Xbox one X will.
For TVs check out the 2017 LG OLED b7.
Can’t really beat it I don’t think

rtings.com does a great job looking at different televisions. That site is the authority of reviewing televisions.

Since you have Sony, maybe a Sony 900E. I have heard too many reports about image retention/burn in on OLED models. Since you mentioned Best Buy, if you buy a warranty from them, it will cover that on an OLED model.

Maybe Sticky will weigh in, he’s pretty much an authority on bulldogs and really big 4K TVs.

You'll get a better picture and performance buying a gaming monitor in 4k

Neither of them support all the games at native 4K. The One X comes close, and on some simpler titles, it can natively render games at 4K, but most titles are still upscaled from a sub 4K resolution using a checkerboard rendering technique. I know a lot of titles these days use dynamic resolution scaling techniques to keep framerates stable.

If you're looking for a monitor that's being specifically used for the best gaming experience, try to find one with the least amount of image processing (to keep latency down), and the highest refresh rates.

Of course it does

Agree with that. For overall performance LG is a very good choice at the moment.

Frankly, I’d say don’t buy now. CES 2018 is in a few short weeks. Once new models and ship dates are announced, you’ll have a good idea of when things are going on close out.

There isn't a massive diff'rence anymore when shopping for TVs like their used to be.

Basically it comes down to; do you have enough cash to buy OLED or do you want OLED?

If no, Then buy the biggest Vizio TV you can afford (M series preferred).
If yes then I would say wait because they are too expensive now.

Need to get one with HDR 10, as that is the new standard, most 2017 model year 4k sets have them.

I just bought an 82" Samsung 4ktv w/HDR, and it is incredible for gaming.

You'll want to buy a set with low latency as well, you basically cannot go wrong with Samsung, Sony or LG; but I would not recommend buying a set from any other manufacturer.

Is it worth it?? Hellz yeah, playing Uncharted 4 on PS4Pro on an 82" 4kTV is like a brand new game, it's amazing. And watching 4k programming on Netflix is absolutely stunning; 1080p upscaled via cable box looks decent as well; not nearly as good as 4k content, but still amazing.

Prices are good too; I got my Samsung for $3200

Other thing to add is that OLED sets can suffer from burn-in, so be careful with them; I would highly recommend a non-OLEd panel now, as games tend to have artifacts liked HUDs.

4K is great and all, but the HDR will be the most visually impactful component. Make sure the TV you pick has a good contrast ratio and can produce and sustain high brightness (measured in nits, 1000 is ideal). OLEDs are great on contrast but so-so on nits and they do suffer from picture burn in so I wouldn't think they are ideal for gaming. Also, there are two types of HDR, HDR10 and Dolby Vision, try and get a TV that does both.

I pretty much disagree with everything in this post. It sounds like what a salesperson at Best Buy would tell someone, aside from the last comment on cost (which is still wrong). There are big differences and when you add gaming to the equation, it becomes much more important to understand your options.

I just purchased my lg uj7700 for one reason. Imput lag. I love to play call of duty online(ps4) and at a tweaked 8ms of imput lag it is among the best if not the best. Unfortunately it is not the best at all the rest. However it is good enough with some cool features and options. Also the price on a 65inch in my area is well below 1k!!!I could never go back to my previous 28ms. tv.
Think modern flippers compared to em flippers.

That's fair. I come form the TV not gaming side, so perhaps I'm out of my element.

Well I still think you're wrong there but we're not in charge of each other monies so we don;t need to agree.

There’s actually 4 HDR standards now on the market. HDR10, Dolby Vision, and HLG are the most known. Dolby Vision is hands-down the best.

And there are definitely huge gaps in TV performance... to the OP, I think you’re going to get a ton of bad advice trying to get information this way. If you know your budget just call up Robert Zohn at Value Electronics. Tell him what you’re looking for and get solid insight and advice from one of the industry’s best independent retailers. Either that, or start researching through trusted review sources.

Bad advice on an advice thread on Pinside? Inconceivable.

If it’s for gaming, get a monitor.

What size of TV are you looking at?

I have PS4 Pro and Xbox One X. Paired with an older Vizio 70" P series (NON-HDR BOO!) Picture is great even non-HDR. Xbox one X does a better job then the PS4 Pro with 4k, even I hate to admit that as I am a PS kinda guy. I also PC game on the TV once in awhile. Although most of the PC Gaming is on the 1440res monitor with 144hz and G-Sync.

Here is an article a couple months old with some listed TV's for gaming.

Good luck!

Just buy the cheapest, biggest, name brand 4k set you can get. Like this one:

This TV is $699 a bunch:

Then just upgrade again in a few years. Not worth it to spend a bunch on a TV, it all goes to zero.
