Very good well-rounded monitor - The image quality is very good for its price range. Also, being able to watch stuff without having to turn on the PC when you're lying in bed or something really helps.

LG 27 inch monitor - I really liked that it was a smart monitor. What I did not like was that it had a remote. It was very difficult try to get things synced. I ended up taking it back and got a non smart monitor.

WesBOct 3, 2026 · Verified purchase ★★★★☆

Excellent for the dorm - Perfect size for my child’s dorm room. Couldn’t be happier with it. Excellent color and image quality, and I really wanted the option to use it as a TV when not studying. It works perfectly for both.
