Breakdown from the 6 most helpful reviews we imported.
I’ve had this screen, well two of these screens for about 18 months and have never had a single issue with them. The picture quality is fantastic and I cannot recall ever having issues with eye fatigue. Very satisfied and happy with these monitors.
Great value at the price point. Picture quality is amazing. Sound quality out of just the tv is very good!
I bought this monitor back in 2021 of July. It’s now 2024 of January. It’s an amazing monitor so far. I have a series x and it’s been doing its job great! No dead pixels. Only genuine problem I have is the power brick for the monitor but besides that I still use this monitor till this day.
My son it. He plays his game on it!!
could be a lil better very dim look Dark and doesn’t really have good graphics look
upon receiving the monitor rather quickly i was greeted with 2 dead pixels after only a week of standard use, I'm not sure if this is a common thing with this model of the said monitor but this should not be a thing especially from LG out of all brands.
