Review: Excellent product! - Good energy usage at E rating, good refresh rate for gaming. Auto HDR facility does make a significant difference to how games look, be aware though that if using this monitor with a PC, it really needs a compatible graphics card, if Nvidia, then at least a RTX 3060 with 12Gb on-board RAM (or Radeon RX 6650). Curve of the screen seems just right for arms length focal point. Lightweight and nice size base stand for use on a workstation/computer desk. The 27" screen at the previously stated arms length focal distance does mean that you have to move your eyes to focus on the screen edges, this is a good thing as it reduces eye strain and tiredness as the eyes are not constantly fixed upon one point which often happens with smaller screen size monitors. Connectivity is good with HDMI and USB-C compatibility. Colour accuracy seems fine to me, but that's obviously down to the individual! All this at a very reasonable price. On the down side, the monitor does have a tendency to flash up warnings that it is going into energy saver mode if you have been using it continuously for 5 hours of more, well that's gamers for you! Easy to put together but the tilt action of the stand is a bit fiddly and requires a significant amount of pressure to alter. Overall, an excellent product that I really do recommend.
Review: Good screen - Good 2nd monitor. Bought it for USB c connection for video. Great price on offer too.
