Display Measurement

The display on the ROG Phone III is an OLED panel that features a 1080p resolution and a very high refresh-rate of up to 144Hz. Although it was something quite extraordinary back in 2019, in 2020 it’s doesn’t showcase the same kind of spec-list advantage versus the 1440p 120Hz panels by some other competitors in the market.

The phone gives you the options to operate at 60, 90, 120 or 144Hz which is quite wide array of selections. Unfortunately, much like other super-high refresh-rate panels on the market, going beyond 90Hz comes at a quite larger power consumption cost.

Colour settings on the ROG Phone III are very varied and customisable, giving you four different predefined display gamut selections. The “standard” profile is the calibrated sRGB target with a default colour temperature near 6500K, so that’s what we measured and what I would recommend users to choose when looking for accurate display colours.

We move on to the display calibration and fundamental display measurements of the ROG Phone III screen. 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 terms of brightness, the ROG Phone III fares well, with manual brightness reaching up to around 423cd/m², whilst when in adaptive brightness mode this boosts up to 652cd/m² full-screen white (100% APL) when under bright ambient light conditions.

In the standard display profile, colour temperature is quite good at the high levels, tracking whites at 6453K. At the mid-levels there’s a bit too much greens.

Although greyscale colour accuracy is quite excellent with a dEITP of only 1.76, the overall error rate when including luminosity is quite bad in our results here, and the reason for that is that the phone is targeting a much higher gamma of around 2.4. Unfortunately this aspect is valid for all colour profiles of the phone and there’s no way to fine-tune or change this.

What this means is that mid- and low-levels will appear darker than they are meant to.

Saturation accuracy against the sRGB target is excellent, with only minor deviations which are exaggerated by the higher gamma target of the display profile.

The Gretag MacBeth chart of common colour tones and skin tones is also quite accurate in terms of colour saturations and hues, however the off-target luminosity because of the higher gamma is the main reason the total dEITP error rate is quite high at 8.57.

Overall, the screen of the ROG Phone III is excellent, although not class-leading. It’s not quite as high resolution or as bright as some competitors, but it still fares very well, and it’s currently amongst a very small number of phones which can claim a 144Hz refresh-rate, although the actual benefits of that over 120Hz devices is rather minor.

Colour accuracy is good, although you’d have to get used to that higher gamma target which produces darker colour tones.

    Just love how far ASUS has come with its phones
  • Kangal - Sunday, August 30, 2020 - link

    Yeah, in 2019... but this year they have gotten worse.
    Just compare the Zenfone 6 to the Zenfone 7 for starters.

    On the ROG 2 vs ROG 3,
    The new device is slightly larger, heavier, and lost the 3.5mm Jack. And it raised the prices.
    But comparing the 16GB RAM vs 12GB RAM, isn't that big deal. And the uplift from the QSD 855 to the 865/865+ is hardly impressive. Or the 5900mAh battery compared to the 6,000mAh battery. Even the screen is the same comparing 144Hz to 120Hz, or the 270Hz-Touch to the 240Hz-Touch. By most metrics the new model is the same or worse than the older one.

    And again, it's more expensive. I think that second chipset (Qualcomm's external modem) is the culprit for this year's lacklustre phones (larger, hotter, battery thirstier, less internal space, more expensive).

    The only point where ASUS has made a notable upgrade is in the camera. And that's on both the ROG 3 and the Zenfone 7. But it's hardly a reason for someone to choose to buy a new ROG3, when they could get the ROG2 on a discount.

    I think I could've been fine with the ASUS ROG 3, if they kept the 3.5mm headphone jack, added a microSD slot, and added wireless charging. That would've made the +$200 price hike easier to swallow. If they included JoyCons in the box, it would've been an instant hit.

    To be honest, I would've preferred they downsized it slightly to around (166 x 74 x 9mm) which is like the size of the OnePlus 8 Pro, any larger makes it unpocketable for most regular mens jeans/pants. Even if that means downsizing the 6000mAh battery down to 5000mAh battery, it's worth it for the quality of life improvement.

    When SD865 prices just got announced people were seeing a price hike of the handsets as inevitable. This phone looks decidedly less "gaming" than the predecessor and that's a big plus for me, and the second C port means the lack of the jack is at least tolerable. How they should cut corners on the optics so much confuses me, I'm wondering if this is a defective unit.
    There's rumor that Samsung is still contemplating bringing back the jack in flagships next year so I'm taking the wait and see approach, the S-Pen for me is worth it, but if Samsung doesn't follow through then I'll come back and buy one of these second-handed. With far superior battery to the Sony, it's already the closest thing to an all-rounder on the market.

    I'm thinking the next year's QSD 875 will be like 8% faster simply because of the 5nm advancement. Plus another 8% speed due to slight architectural improvement in the X1 core, and modem efficiency.

    Yes most important, it should have the 4G/5G modem integrated (hopefully)... and that should mean better efficiency, and slightly larger internal space. So we could see the 3.5mm Headphone Jack make a comeback because of that.

    But Samsung has killed the Jack for good. They have their own wireless earphones for sale. They got rid of it on the Note10 for no good reason. It's not coming back. Heck, even if they wrongly accuse the internal space restrictions, which is not true, there is no reason that they cannot integrate the 3.5mm Headphone Jack into the underside of the SPen.

    I'm hoping this year has negatively affected all OEMs that they re-introduce some wanted features next year like Headphone Jack, microSD... on top of REDUCING the prices down (-30% ?) to regular levels to ensure strong sales/continued sales. I think this year proved that marketing wasn't strong enough to deceive the consumers.
  • s.yu - Wednesday, September 2, 2020 - link

    lol I would bet on a comeback of the 3.5mm than a 30% price drop. Anyhow, the market hasn't exactly been exciting this year so I'm truly not in a hurry to upgrade, so I'll wait and see until there's something solid suggesting no jack again.
  • flyingpants265 - Tuesday, September 1, 2020 - link

    Joycons are stupid, it should be a whole PSP-like controller case that locks in place, to literally turn your phone into a PSP. Then we can have serious game development and ports for phones.

    This should have been available since 2007 or before. 13 years later and we're still using weird flimsy attachable joycon things.

    The current Chinese Bluetooth psp-style controllers suck bad.

    The most awaited review is finally here
    Wanted to see how it fares against other flagships
  • Kishoreshack - Friday, August 28, 2020 - link

    6000 mah battery with 865 plus & 144hz display is an instant sell for me
  • nico_mach - Friday, August 28, 2020 - link

    Yes, this, I think this phone is more compelling outside of its gaming. Esp in comparison to iphones - they dominate the performance but usually ship with tiny batteries. Android phones need to carve out a niche, and this phone does that.
  • melgross - Monday, August 31, 2020 - link

    They still have some if the best battery life. And they’re not “tiny” batteries. iOS doesn’t need very large batteries as Androud phones do.
