Using a HDMI 2.1 TV as a monitor [Cheap 4K 120Hz G-SYNC OLEDs]

I have been curious about this for a while now. The best HDR monitors currently are the TVs. They also have the best contrast ratio. And at a 120hz, they are pretty nice in terms of speed, even if they aren't blazing fast. Has anyone actually tried this here? I think the ergos are going to be a little rough for sure, but it could be very good for gaming and programming.

Yes. Dozens of us throughout these forums use it as a monitor now. A little known secret as a dream computer monitor, though sometimes it has firmware bugs that can be worked around. All that Visual Studio and PhotoShop beauty spread all over your screen.

The 2020 CX OLED's are the cat's beans -- 4K 120Hz "G-SYNC Compatible" and BFI strobing at both 60Hz single-strobe and 120Hz!

Recommendations when using a 48"-to-55" OLED TV as computer monitor:

- Recommended viewing distance 1 meter (3-4 feet)
- Mount on the wall at back of desk, or get a deeper computer desk (even cheap IKEA)
- Turn on taskbar autohide
- Turn on orbiting (prevent more highly-objectionable readable tiny-text burnins)
- Use dark Windows themes that also include darker title bars and window frames
- Lower brightness a bit
- Turn off HDR except for movies/games
- All the common sense OLED-as-monitor tips.

Just like sitting 24" (2 feet) away from a 24" screen, you're sitting 48" (4 feet) from a 48" screen. It's not uncomfortable as a computer monitor when optimized like this; actually quite very pleasing. Although I am not lucky enough to have one here right now, I have spent time in front of one as a computer monitor elsewhere. It is eminently quite practical and eyepleasing.

Don't worry about burn in FUD. Yes it burns in nasty if you push its limits (like running a car at 8000RPM all the time). Gently run it (like driving car at 2000RPM) and it will happily last years. Any ultrafaint burnin that shows after 3 years sometimes isn't even nearly as bad as some LCD quirks (like VA splotchiness). You're trading pros/cons for different pros/cons, live with them. Just try to overcome your OLED burnin fear; this is usually the biggest step to overcome when using this OLED TV as a monitor; it ends up being much ado about nothing -- much like not caring nearly as much about your car's 2nd scratch after the car's 1st scratch.

Don't get it if you hate dim Windows desktops. But most computer monitors are run dimmer than televisions, and that plays into your OLED nirvana favor. Prices can get really good during Prime Days / Black Fridays / Boxing Days. The sweet spot size is the 55" model which is usually more-in-stock than the 48"

Yes, go ahead and and sometimes turn on HDR goodness and get the brilliant HDR whites, for those gaming moments like playing a game of upcoming Cyberpunk 2077; treat yourself now and then; it's moving imagery anyway instead of static burninable imagery. Just try to hide your HUD whenever you can.

It's also a dream with emulators, with the 60Hz single-strobe BFI, provided you're running at the maximum BFI setting (to avoid the double strobe BFI). And you can use 120Hz strobing instead, if you don't like 60Hz flicker but prefer the best motion clarity that any flat panel can offer today.

Not a bad price at less than $1500 during good sales. At $1200 on the best sales, it's a bargain 4K 120Hz OLED computer monitor. No way to get million-to-one contrast ratios for that cheap yet (until the upcoming commoditization of MiniLED FALD LCD in the mid 2020s decade).

The OLED is a smidge laggier than a 240hz esports monitor, but a lot less laggy than a plasma TV. And this OLED is one of the first true OLED HDTVs with less motion blur than a plasma TV (during the BFI mode). You may have to put up with some firmware bugs, but they typically can be worked around.

The CX's are a best known secret as a dream office/gaming computer monitor, when adjusted properly.

Great post Chief! I think you are combining the CX with the C9 of last year, but I don't think that's the same TV. I haven't seen that TV dip below 1490 ever for example. The comments section seems to imply that the C9 can only do BFI up to 60hz while the CX can go 120.

Also, I am not just interested in the OLED, but also the best of the HDMI 2.1 LCDs as well! For example the Samsungs have made a definite focus on gaming too.

I think the most convenient distance, in terms of my furniture setup would be about 2.5 feet. I wonder how big the TV would look at that distance...

[Chief Blur Buster]

Oh yes. The 1200 I mentioned is for the C9 model, you are right.

The 2.5 foot might be a tad close for 55” but you can make do with 47-48”, it’s like multi monitor with four monitors in a 2x2 grid. 48” 4K is the same DPI as a 24” 1080p monitor.

It’s a workable setup nowadays. Good native-input high-Hz TVs can be more gaming monitor sweetness than expected, especially with the VRR and HDR features available in new 4K TVs nowadays. RTINGS can attest to helping find the right TVs that pass the desktop comfort test.

I have been curious about this for a while now.

I own the 48CX. I don't use it as a monitor, but I have it connected to my PC, and I sit pretty close when gaming sometimes, at least.

If you have any basic questions, let me know. FYI, I haven't been able to get my hands on a 3080 yet (still have a 1080 TI), so I can't speak to its G-SYNC performance at the moment.

Nice

If I ever get my hands on a 3080, I am jumping on this setup. I think I am fully convinced about it's benefit.

For G-Sync a GeForce RTX or GeForce GTX 16-Series GPU is required.

Still can't get my hands on a 3080 either. The scarcity of it and other new high ticket gaming hardware this year is nigh unbelievable.
