Top screen, with some random quality control

  • good colors
  • High resfresh rate
  • GSync
  • The quality can be disappointing (see review)

My first purchase was very disappointing, the screen had an orange "cloud" in the bottom right corner, the menu lever also felt a bit rickety. I sent that screen back and after some further research it turns out that this monitor can be a bit hit or miss in terms of quality. Finally decided to give it another try and ordered a new set. Both screens are excellent this time. Image is great, no weird effects. The menu stick is also a lot stiffer / firmer. Obviously had a Monday morning model the first time.

27” 1440 is a good upgrade over my previous 24” 1080p. The refresh rate is great (especially with GSync). Image is also a bit sharper and the colors are a huge upgrade (first had TN) in short, very satisfied with it!

Another tip for new owners: if you notice that the brightness seems to fluctuate, the monitor has energy saving turned on by default. Turn it off and it won't bother you anymore.

Orange glow across screen

  • Thin bezel
  • Best 144+ hz for the price
  • High chance of screen glow

Ordered for the first time and as indicated here, there was also an orange glow in my screen. Returned and got a new one and the same problem again... Now I read somewhere that 30% of the screens have this problem. Now Coolblue can't do anything about it, but I think that Coolblue should point out to LG that this is not really customer-friendly... LG should check products better before they are scrapped.

Good display for the price

  • Easy to set up
  • 165hz display
  • Many ports (for PC and console)
  • Not true HDR

So far easy to use and great to play on. I would have liked to see more image quality settings; except that this is available through software for PC (but not in itself).
