Today we are checking out the MSI MPG 321URX, our first look at the new generation of QD-OLED gaming displays that offer a 4K resolution and 240Hz refresh rate. Up until now, OLED monitors have been limited to 1440p or ultrawide screen sizes, and it is safe to say there has been a fair bit of hype surrounding these new 32in 4K models. We put the MPG 321URX through its paces and find out just how good this gaming monitor really is.

If you have read any of my previous OLED monitor reviews on KitGuru, you will know I think the technology is incredibly well suited to gaming. Not only do you get an effectively infinite contrast ratio and immersive HDR experience thanks to the per-pixel dimming aspect of OLED, but the response times and motion clarity on offer are absolutely superb.

That means we can have high hopes for the MSI MPG 321URX, utilising a 3rd generation QD-OLED panel from Samsung. Like most 4K screens using this particular panel, it offers a flat 16:9 experience, while MSI claims up to 1000 nits peak brightness in HDR, 99% DCI-P3 coverage and adaptive sync support.

Naturally such a screen doesn't come cheap, as it's up for pre-order at £1299 from OCUK, though US buyers can find it at a more attractive $949 price point.
