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

There's a few different HDR modes to choose from, but the behaviour is as expected – the HDR 1000 Max mode peaks at 1000 nits for 1% and 2% APLs, before dimming as the window size (APL) increases. The True Black mode is dimmer at around 450 nits peak, but doesn't roll off as aggressively as the 1000 Max mode.

Greyscale

I tested three modes for greyscale performance in HDR. The first, and default HDR mode, is the HDR Game setting. Now, you'll see that all three modes are still too warm overall, but I think this is the best choice due to its EOTF tracking. In the past I've criticised Evnia for this mode, as the image is actually a little too bright across the range. However, while it's not technically accurate, I do think this results in a more pleasing image than what the other modes can provide.

The HDR 1000 Max mode, for instance, is too dark across the range and rolls off early – only slightly, but it gets worse at larger window sizes as we will see shortly.

The HDR True Black mode is more accurate, closely hugging the desired curve, though it's ever so slightly too dark across the middle of curve. You also miss out on the peak brightness of the panel when using this mode, so it's not my personal preference.

When looking at EOTF tracking across a range of window sizes, we can see the HDR Game mode is generally too bright across the curve, but does roll off slightly at the end – and progressively more so, as the APL increases.

However, it's much better than the HDR 1000 Max mode, which is not only too dark across the early stages of the curve, but rolls off early even more aggressively than the HDR Game mode.

The HDR True Black mode performs better, though it still appears slightly too dark across the curve, especially at the 25% and 50% APLs. I would say this is the mode that's most accurate, in the sense it comes as close to the intended target. That said, I do think the HDR Game mode will look the best from a subjective perspective for HDR gaming due to its brighter presentation, while it can hit 1000 nits, whereas the True Black mode is limited to 450 nits.

Colour Accuracy

Looking at the HDR Game mode for colour accuracy, the average deltaE 2000 of 2.42 isn't bad, though there's clearly room for improvement.
