Excellent for my uses 6/27/2020 10:01:01 PM

Pros: Size, brightness, features live up to advertising.

Cons: Potentially too large for close (normal desk) use. I regularly use this as a pseudo TV, viewing it from about 3 feet back and that's about perfect.

Overall Review: Really love this thing. I spend a lot of time gaming with controller closer than 'typical' TV setup and this was the perfect compromise.

Amazing HDR Display, and it's HUGE! 5/2/2020 6:21:14 PM

Pros: First of all, it's huge. It's far bigger than I imagined it would be. Secondly, they absolutely nailed the HDR implementation. It's perfect.

Cons: - Expensive.
- Not many HDR games to flex this monitor's muscles, and not every HDR game implements the feature well.

Overall Review: I was very picky when looking for a monitor to upgrade to. I was looking for a VA panel, well-implemented HDR, FreeSync 2, and at least a 120Hz refresh rate. This monitor checks all of the boxes.

The first game I tried out was Jedi: Fallen Order. While it looked good, I was expecting better from a monitor of this caliber. Then I tried out Gears Tactics, and wow it was amazing! I turned the HDR brightness and contrast all the way up within the game settings, and it's beautiful. The bright spots are extremely bright, and the dark spots appear completely black. The picture just feels alive.

With the right game, this monitor is fantastic. I would absolutely recommend it.

Love this monitor - just takes some work 4/7/2020 9:12:07 PM

Pros: - Amazing picture
- Very vibrant colors and the refresh rate is stellar
- Perfect size for me!
- Cool projector for the logo, was a nice touch
- Love the cable management

Cons: - Takes time to set up properly

Overall Review: I just got this monitor in and I have seen on other sites where people are slamming it for "blurry text" due to the RBG layout of the panel. If you do some research, you will find that these issues are merely OSD settings you need to tweak and a few settings in Windows.

Once you do that, the display looks amazing and games are so immersive from the get-go anyways. The fixes resolve the "blurry text" issue. I replaced a Samsung 60HZ 4k TV with this monitor and I couldn't be happier.

awesome 11/16/2019 2:04:33 PM

Pros: - huge
- very big
- not small

Cons: - windows 10 brought these up with them zoomed in 300%. i had to go into settings and adjust down to 100%.... awesomeness happened.

Overall Review: bought two of these. i'm in the middle of a new pc build.. these will go with the new pc ....i have two asus 35" ultradwides .. .. these are bigger horizontal than the ultrawides, plus double the vertical . i spend a lot of time on my pc because i write a lot and trade cryptos alot, which is why monitors are always a good investment for me. the more real estate i have the better.. these have the real estate .

these are very big .. they are still good size though .. i think we are getting close to maximum size.. maybe until quantum electronics and pcs become a thing. i expect soon we will have monitors that surround our desks . virtual quantum 3d computing .
