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.
MSI includes three HDR modes: True Black 400, Peak 1000 Nits, and EOTF Boost.
Brightness
First things first, overall brightness behaviour is as we've come to expect from QD-OLED – the Peak 1000 nits mode does indeed hit over 1000 nits for the 1% and 2% APLs before dropping off as the window size increases, whereas True Black 400 is dimmer overall.
Given this is a 4th Gen Samsung panel, it's not quite as bright as a 5th Gen panel like the MPG 341CQR we reviewed earlier in the year…
While it is also ‘only' True Black 400 certified, rather than True Black 500. Still, behaviour is as expected for this particular panel technology, and we do have to remember it's currently selling for just £500.
Greyscale
Overall EOTF tracking performance is also as expected. The True Black 400 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, and generally it is very successful.
Colour Accuracy
It's also good to know that all three modes offer very similar levels of HDR colour accuracy, too.
