Display Measurement

The OnePlus 8 and 8 Pro feature brand new display panels that represent the best in their respective categories. Since the OnePlus 7 Pro, the company has been able to source amongst the best and cutting-edge panels from Samsung, and the OnePlus 8 Pro is no different. Using the latest emitter technologies, a 1440p resolution and a 120Hz refresh rate, there’s very little to be wished for in the display of the new flagship.

The OnePlus 8 has an equally excellent screen, however with its 90Hz and 1080p resolution is just shy of having the best specifications.

We move on to the display calibration and fundamental display measurements of the OnePlus 8 and OnePlus 8 Pro screens. As always, we thank X-Rite and SpecraCal, as our measurements are performed with an X-Rite i1Pro 2 spectrophotometer, with the exception of black levels which are measured with an i1Display Pro colorimeter. Data is collected and examined using Portrait Display's CalMAN software.

Display Measurement - Maximum Brightness

In daylight, both phones have excellent brightness reaching up till around 800nits on full-screen white content, representing the best results we’ve measured on an OLED panel, just shy of the LG G7’s ultra-bright LCD screen. Under manual brightness the phone reach about 430 nits.

On the regular OnePlus 8, the phone has good colour temperature although the reds are only every so slightly above a perfect grade. The display’s gamma curve however is a tad more off with too high a total gamma of 2.28, making tones appear darker than they should be. This seemingly is especially present in the lower intensity tones as the phone clips a lot of content to black or near-black.

The zig-zagging measurement results here are pointing out to some sort of artefac of the screen calibration which is a bit abnormal, but something we did see on occasion happen on some devices in the past.

On the OnePlus 8 Pro, the gamma results are significantly better and the phone is able to track nearer to the optimal 2.2 target. The 8 Pro’s biggest issue though is colour balance as in the natural profile things are far too much dominated by reds – or rather say a lack of blue. The average colour temperature ends up at 6216K and pure whites end up in a quite disappointing 6155K which is pretty much immediately visible on the phone.

sRGB saturation accuracy of the OnePlus 8 is quite good and we end up with an overall dEITP of 2.75 which is within the imperceptible margin for most users.

The OnePlus 8 Pro’s colour accuracy isn’t nearly as good. We’re seeing worse results across the board and when looking at the gamut results this seems to be due to too weak blue tones, shifting the whole cyan-blue-magenta saturations from where they should be. The most noticeable effect of this is again in whites where they’re far too warm.

In the Gretag MacBeth colour chart with most common tones and skin colours, the OnePlus 8 fares well in terms of its colour accuracy, only being more handicapped by its higher gamma target which makes all tones appear darker than they should be. Overall, it’s still an excellent result for the phone.

The OnePlus 8 Pro nails the luminance component of the test patches, however it has more significant hue and saturation deviations that more easily stand out to the eye

Overall Display Conclusion

Both the OnePlus 8 and 8 Pro have excellent displays. The 90Hz and 120Hz refresh rate capabilities of the phones is what really makes them stand out in everyday usage. In terms of colour accuracy, things aren’t at all perfect. The OnePlus 8 has issues with the gamma curves, having a too high target resulting in too dark tones, especially at the lower intensity levels where things can clip to black.

The OnePlus 8 Pro’s issues are more severe as whilst its gamma is good, it has more noticeable problems with some hues and especially saturations in the blue spectrum. The biggest issue is its far too warm colour temperature with whites falling in at only 6150K. OnePlus likes to brandish awards regarding the device’s screen accuracy, but legitimacy of such figures always come in question as such cherry-picked results never match proper independent analysis. Nevertheless, you can set up a manually adjusted colour temperature that will solve the main negative about the screen.

    Same here. The dual speakers setup used on OnePlus7/8 does not sound good, or correct, for video viewing.

    What happened to display audio that don't need speaker holes? Sony and LG had them a few years back and then never heard from again.

    I really love the one plus display
    It feels even smoother & sharper than s20 line up
    One plus has been constantly delivering better displays even than the display manufacturer Samsung itself
    It's a shame Samsung who manufacturers display can't deliver the smoothest sharpest display
    On the market

    It seems phones are more about bragging rights than how they actually perform now a days. $1000usd for a phone? No thank you. Reply

    It's about profit, market share, and demand. They just started arbitrarily raising price, and decided it was better to sell slightly fewer phones, at a much higher price. It's called market capitalism. It's awful.

    Also, around here, the telcos are helping subsidize certain phones again, AND financing: every phone is available for $0 now. So we may only see higher prices.

    Nexus 5 was $299 (I think? Don't remember really). OnePlus One was around the same price.. Redmi K20 whatever was $420

    If you look at Realme X, it's $145 USD for a 1080p FULLSCREEN phone with SD765. So they can easily make budget phones and sell them at a slight profit... But they artificially limit sales of phones by region!! It barely even works in North American networks.

    Exactly, the Android OS is already saturated and removing features like Filesystem advantage and shoving iOS crap into it. The worst part is as you said the insane price tag, this POS phone what does it do better than an S10+ for the same price retail currently, for non tinkerers it does nothing. It has a BL unlock but apart from that S10+ trumps this garbage clone CCP device in everyway. Reply

    Their commitment to the display tech is a testament in itself how far they have come
    They are literally beating display manufacturer SAMSUNG in terms of Quality

    Why is the manual brightness on android phones so low? Reply
  • Andrei Frumusanu - Monday, June 29, 2020 - link

    Probably to avoid having people needlessly blasting the brightness at full intensity all the time. Reply
