MSI MPG 271QR QD-OLED X50 Gaming Monitor Review
Calibration
Using out of the box settings, the monitor delivers exceptional colour reproduction, with 100% of sRGB, 995% of AdobeRGB and 98% of DCI-P3. DCI-P3 will creep up to 99% when testing in HDR mode too. I set the monitor to 100% brightness, and this still held true, with AdobeRGB dropping to 94% but everything else held up perfectly.
The Gamma curve is near perfect, only a slight deviation, but honestly, this is common on OLED as any fraction of auto backlight adjustment from the panel can throw it out, however, this is still one of the best results I’ve seen on OLED.
I ran the test again in USER mode, and with brightness locked at 100%, and as you can see, it’s perfect!
Gray ramp is excellent too, with a fairly flat response from around 40% RGB input onwards, and while slightly above our target 6500K, that’s still very common, and often setting the monitor to a Warm profile will smooth this out further, but it’s preference at this point.
In SDR mode, the monitor peaks out at 300 nits brightness, with perfect black levels thanks to the QD-OLED panel. In HDR mode, you can operate it with a HDR True Black 500 Nits profile, which looks stunning, but as I said, there’s a boosted mode that allows for up to a 1000-nit, but this will cause more auto brightness adjustments on excessively bright scenes, and ruins the colour accuracy; but it does look dope vibrant for gaming.
Colour accuracy is at such a good level, you could comfortably use this monitor for professional colour grading work, it’s just that good. Anything under 5 is OK, under 3 is excellent, under 1 is phenomenally accurate, and here were sitting below 1.0 for everything but cyan 1F.
I performed a calibration, and it basically dialed in a little more green, which did bring the accuracy of 1F more in line, but overall, actually made the monitor slightly less accurate. Wasn’t worth it, differences like this are near impossible to detect with the human eye, so a big thumbs up to MSI for doing a stellar job calibrating this from the factory.
