Tip top!
I've had it for 7 months now, and it's clean.
I was looking for a 32" or more for an acceptable price with IPS and 144Hz. This model is more or less the only one that met my criteria and I don't regret my choice.
The build quality is decent for the price, and the panel is very good quality in my opinion. However, I'm not a professional graphic designer and don't have the equipment to assess the calibration. All I can say is that the colours are vivid and the viewing angles generous. In short, IPS. Freesync works perfectly, and there's no tearing of the image, even beyond 60fps.
No worries about dead pixels or the like as far as I'm concerned. I can only recommend this screen, given its unbeatable value for money.
