What owners think
How owner sentiment changed over time
ExclusiveBased on when customers actually wrote their reviews - so you can see whether early praise held up.
- Q2 202661/100
Most buyers found the monitor good value with clear picture, but a defect causing purple lines and mixed feedback on brightness/ergonomics lowered sentiment.
- Purple lines appeared and multiplied after three months; one review warns to avoid this model.
- Brightness adequate for some, but barely enough; HDR underwhelming; not ideal for bright rooms.
- No height adjustment, limited swivel; base moves with swivel; riser or stand recommended.
- USB-C power delivery only 10-15W; insufficient to charge laptops, requires separate charger.
- Q1 202668/100
Buyers praise screen real estate and color accuracy but report issues with sturdiness of the stand, missing built-in speakers, and video card compatibility requirements.
- Large 32-inch screen excellent for multitasking and professional work.
- Stand is not sturdy even after proper installation.
- Monitor lacks built-in speakers, a surprising omission for some buyers.
- Requires video card upgrade for full resolution; works well after that.
