Uncalibrated – Maximum Backlight Level
I have observed that QD-OLED panels give up some peak brightness to their non-QD counterparts. But the MPG271QRX’s 248 nits is still plenty of output for an office or media room. The variations seen in the above chart indicate different approaches to engineering. Any OLED is capable of 400 nits in SDR mode, but that choice increases power consumption and shortens panel life. It also increases the possibility of burn-in. Running at a lower level is more practical for the long term. Black levels are, as usual, unmeasurable, as is contrast. All OLED panels are equal in this regard.
After Calibration to 200 nits
The MPG271QRX doesn’t appear to vary brightness with content, so I was able to set 200 nits using a full-field pattern. This makes no difference to black level or contrast measurements. ANSI or intra-image contrast is also unmeasurable.
Test Takeaway: I can’t overstate how much better OLED image quality is over LCD. The MPG271QRX’s true 0% black levels mean the image appears three-dimensional. It’s as if one sees into the monitor rather than looking at an image rendered on a flat surface.
