Curious to hear what others are using to game on if anyone is using a larger TV for their pc gaming.  I'm on an older 1080p tv at the moment, but looking to pick up an lg C1 oled this year....maybe the 77 inch. Looking to see what mini led options come out this year as well with local dimming zones if the price is right like the TCL models of the last couple years.

Does the steam link app let you do 4k? 4k 120? I have the hardware steam link and I think it's only 1080p?

I recently bought a 75" Sony X900H to dual purpose as a home theater TV and couch co-op gaming display for both consoles and PC. There's promises up and down from Sony that VRR will be implemented, but it keeps getting delayed. If you're fine waiting for VRR or just running at a static 60 or 120 Hz, I definitely recommend it. I haven't gamed on it yet, but streaming content to it is beautiful. It also has great ratings for local dimming and input lag/latency, which is what I assume you're prioritizing as a gaming display. Best of all, it's significantly cheaper than a lot of the competition: the 75" is on sale right now for $1599 (or $1569 if you can buy from Costco) compared to around $2200 for the Samsung Q90T or $3800 for the LG C1. The upgraded X950H trades specs back and forth, in that it has better viewing angles and HDR capability, but loses on contrast and input lag.

Could you use a 4k tv as a replacement for a PC monitor?

Thanks! I'd love to find a 32 inch 4k tv as a monitor replacement that has HDMI 2.1, but I know that's like asking for a unicorn that rides on a rainbow

Yeah there are either small monitors or large tv's, the in between range is few and far between.  The TV's even at 55" are pretty reasonable, a good large 4k monitor (like the new ASUS) cost a ton of money (and doesn't even have hdmi 2.1) I'm hopeful as a monitor the new smaller OLED's (42" coming this year) will fit that in between spot.  Although I plan on getting a large secondary tv for gaming on my computer from the couch.

Why do you need HDMI 2.1 when they have DP1.4 running directly through a G-Sync Ultimate controller? There are alternatives to the ASUS and Acer 32" monitors if you're willing to compromise on HDR ratings, in exchange for HDMI 2.1 and Freesync/G-Sync compatible VRR certification.
 
The biggest issue when it comes to 32-43" 4K monitors is that there aren't that many panels being made. They're a PC gaming niche, whereas for $400-600 you can easily grab a bargain brand 55" 4K TV. That where all the panel makers are making the most revenue, and run way more production to meet demand. Economy of scales and all that.

You are right, 2.1 isn't essential on the ASUS if it has displayport, but for the $3,000 price point, it seems like it should have it and if you are connecting a non-pc up to it, hdmi 2.1 is the more relevant standard.  You are correct too that the 32-43" space is pretty much a no mans land between pc monitor and TV.

Sort-of, you can make it work but it won't be the same. Response time and text sharpness may not be good.

TVs and PC monitors have different priorities.

Nowadays you can actually play quite well on TVs, only in the area of the frame rates there are bigger differences.
However, since I still like to use a mouse and keyboard, a 40+ inch device in front of my face is quite uncomfortable.

I have an older 60" Plasma TV I use for casual gaming. I'd never use it for anything competitive. I have a long HDMI card that runs through the wall from my computer to the TV. Then a wireless keyboard and controller for single player sightseeing games.

What about the sony x850h 

i suppose if you have a nice 4k 120hz OLED 48+ inch TV in your living room, it may be a good idea to build a silent gaming computer connected with 4 xbox controllers and just use it as a console. no CSGOing, but can do anything else just fine

alot of TVs come with freesync, anyway if you just play casual is ok, i not suggest it for competitive fps play because the response time 

I use to game on a 40inch RCA back in the day was not the best expectance especially with the tearing using an RX 480 and that was a 1080p display with HDMI but that was probably 8 years ago with my FX 8120 rig. I have a Samsung 4K TV 50in maybe I should try running a few games on that to see how it works. Will update with future results.
