Great - Product is very great and a big upgrade from previous monitor.

Osc121Oct 24, 2026 · Verified purchase ★★★★★

WOLED Monitor with beautiful contrast. - The site doesn't show the type of panel it has but it's WOLED. Out of the box the colors are a little too saturated so tweaking a little is needed for accurate colors otherwise it's amazing for 350.

Great budget OLED display - The monitor has a nice glossy finish and decent HDR with support for 240hz refresh rates. It's an OLED so all content visually pops in comparison to regular IPS displays.

Genuinely amazing. - This monitor is such an upgrade compared to my last one. I love the way it looks and how it fits so well with the rest of my setup for a price that won’t make my wallet die. Mostly using this to play fast paced games and I recommend 100 time out of 10.
