The MPG271QRX responds automatically to HDR10 signals from games or video with two special picture modes, True Black 400 and Peak 1000 Nits. Stick with True Black, it’s the default. It has the best color and luminance accuracy and will ultimately deliver the best image.
HDR Brightness and Contrast
If brightness is a priority for you, the top three screens have higher peak output than the MPG271QRX, but they have no more contrast. Black levels are the same. The brighter screens might have a little more punch in the highlights, but the QD-OLED panels will have more saturated color. It may be worth doing your own side-by-side comparison to find a preference. In this group you can have extra color or extra brightness but not both.
Grayscale, EOTF and Color
The MPG271QRX has visually perfect HDR grayscale tracking and a nearly flawless EOTF trace. Shadow areas are a tad dark but not enough to obscure detail. The tone map transition is at 60% which is correct for the measured black and white levels. In the color test, everything is over-saturated, which lends a lot of punch and impact to HDR content. It isn’t strictly accurate, but in practice, it looks very good. Tracking is linear up to the 90-100% points, preserving detail rendering in highlight areas. Hues are on target for all primary and secondary colors. The Rec.2020 test shows the same behavior with an end to the color saturation fun at around 90% for red and 80% for green. Blue makes it up to around 95%.
Test Takeaway: The MPG271QRX has a LOT of color available for HDR content. It tracks well with accuracy that’s similar to what I observed and measured in SDR mode. With true black levels and infinite contrast, it’s the best possible way to enjoy HDR content. And this is true of every OLED I’ve reviewed. The MPG271QRX has more color than others though which puts it a little ahead of the curve.
