Finding a Good UHD TV for use as a computer monitor.

Hey guys, I have a 5 year old TV I've been using as a computer monitor for a long while now and I'm ready to upgrade. I know the preferred choice for PC's are monitors, however I want to future proof a bit as I'll probably have this TV for the next 3-4 years. To me that means UHD. But to me a UHD monitor just doesn't make sense, they are nearly as expensive as TV's and too small to benefit from 4k with most being around 27". Plus since I have my TV wall mounted it's easy to re-purpose as a normal TV for when friends come over to watch movies/shows or play games. Basically I love the benefits of a Large TV, but it also has to function as a proper computer monitor. So what I'd like help with is finding a TV for use as both a gaming and work monitor.

My budget is $2,000 USD, but it is slightly flexible provided there's an outlier.

Here are my wants
~50" preferred, but willing to go slightly larger.
1. 10 bit, 120hz Native refresh panel
2. Full HDMI 2.0 and 4:4:4 Chroma SS Capabilities at 4k 60hz
3. HDCP 2.2
4. HEVC H.265 encoder for 4k streaming content
5. Good input lag

Extras that I'd like but aren't necessary
Local Dimming
USB Ports


I realize a TV like this simply may not exist, however the Vizio P series minus it's Chroma Capabilities and HDMI 2.0 bandwidth restrictions came remarkably close to fitting the bill at an incredible price.

Would the Samsung UNHU8550 be a good fit? Anyone that has a UNHU 8000 series care to chime in?

Edit: input lag is fairly high, and the panel is 8bit :/

If your card has Displayport 1.2 capability, this may be a good choice:

The 58" is on sale for $1999 at Panasonic.com.

Lowest input lag that I've seen is about 17ms on the Vizio P series, but that's on only one port with game mode turned on. 65" goes for about $1800.

People seemed to like the 55 UB8500 which Microcenter was selling for around 900 and a few other places (newegg and maybe frys?) had for around 1k.
Has 444 and everything. Passive 3D, IPS screen (if you like that) as well.
I had it for a month but it was too small for my taste - ended up with the 65 vizio p.
They also have a 49" version which may be cheaper for a monitor as well.

EDIT: Sorry these are only 2560x1440. There are no 120 Hz+ 4k monitors.


Don't bother with this. The image quality will be awful. Text will be unreadable due to the pixel arrangement / spacing. It will have massive input lag and the image processing designed for video will be horrendous when applied to a moving cursor or scrolling browser window.


Native 120 Hz input? Forgot about it on anything other than a gaming grade monitor. The only one in existence with even an 8-bit TN panel is the Asus ROG Swift. If you wait for a month you can get the AHVA (pseudo-IPS) Acer XB270HU. Both of these are 144 Hz. The vast majority of 120 Hz+ panels are only 6-bit.

I've been looking at the Samsung UN50HU8550. If I can get the correct chip, it's capable of 4:4:4 @ 60hz. It has a 120hz native panel, and theoretically since it has full bandwidth (18Gbps) HDMI ports, [email protected] theoretically should be possible. It's also nice, because it's easily repurposable for watching shows, or couch gaming with friends.

120 Hz on anything called a TV, especially at UHD, is not usable on a PC. It will have way too much ghosting and lag. These 120 Hz TVs are designed to display 24 fps 3D movies while displaying the same frame multiple times per eye, not 120 discrete frames per second. This is why the Asus ROG Swift is such a big deal, since after such a long time they finally made a 2560x1440 monitor @ 144 Hz without ghosting. Don't even remotely expect anything of that standard from a TV manufacturer, especially in an immature UHD TV.

As for the UN50HU8550, I'm unable to find anywhere that it actually supports 120 Hz input over the HDMI 2.0 port. It's again probably only internally used for 3D. Also, 3D Vision and HD3D will not work over a HDMI 2.0 port at full resolution even though its capable, as nVidia and AMD have no intention of supporting HDMI 2.0. They've settled on DisplayPort for the future.

Yea, I'm not so much concerned about 3D, including Nvidia, I'd probably rarely, if ever use it (I had a laptop with Nvidia 3D, and as cool as it was, I just never really utilized it.) I'm honestly more concerned about being able to use it as a monitor for [email protected] at 4:4:4 chroma. I wish more TV manufacturers outside of Panasonic would implement DP as it's a far superior input, but I understand it's all in the interest of HDCP2.2 and I have to deal with the options I have. As far as other options I've hard the Samsung JS8500 series TV's may be out as soon as next month, so if my HU8550 doesn't have the right chipset to support 4:4:4 I'll just let them keep it and wait to see what the spring lineup from different manufacturers looks like.

So Steph. It recently came to light that I can possibly get this TV for around 1800 after taxes, so I'm digging for information about it right now, thanks for the information. It's a shame the 50" was never released in the US.
