HDR Testing

Following on from the SDR results on the previous page, here we re-test the relevant areas of the display with HDR enabled.

Brightness

Starting off with HDR luminance, both the Peak 1000 nits and EOTF Boost modes behave as expected – they hit just over 1000 nits for the 1% and 2% APLs, before dimming as the window size increases.

The True Black 500 mode is more uniform overall, starting off at around 500 nits, though it does still drop off slightly once we get past a 10% APL.

Still, it's interesting to compare the Peak 1000 nits mode to the MSI MPG 321URX from a couple of years back, as despite the absolute peaks being similar, the 322UR X24 is generally brighter across the board.

Likewise, its True Black 500 is a decent step up from the True Black 400 mode found on the 321URX, so the move to 4th Gen/Penta Tandem QD-OLED certainly has its benefits.

Greyscale

Overall EOTF tracking performance is also as expected. The True Black 500 mode is generally accurate across the curve and doesn't roll off significantly, even at bigger window sizes, whereas we know the Peak 1000 nit modes do roll off at increasing rates, as a result of panel dimming. MSI's EOTF Boost mode is designed to fix that, though I recommend watching the video for a visual example of the different modes in action!

Colour Accuracy

The good news is that all three modes are very colour-accurate for HDR usage, and it won't make a huge difference which of the three you use in this regard.
