Owner sentiment has cooled since launch
- Q4 202580/100
Buyers found the monitor good value for work, with mixed views on gaming. One received a used unit when new was ordered.
- Good value for price, suitable for work from home setups.
- Picture quality is decent but not recommended for gaming.
- Curved design helps preserve detail, praised by Spanish reviewer.
- One buyer received a used monitor instead of a new one.
- Q3 202580/100
Buyers in Q3 2025 praised the monitor's value and color after calibration. Some noted shakiness, lack of 4K, and USB-C limitations.
- Great value for the price, exceeding expectations for work and daily use.
- Color is good after correction, but missing 4K resolution was a downgrade for some.
- Monitor is a little shaky, as other reviews note; USB-C only charges, doesn't transmit data.
- Curve stands out depending on the app, especially for glasses wearers, but users adapt.
