The OnePlus 7 Pro's 90 Hz screen will sometimes silently switch down to 60 Hz

The OnePlus 7 Pro's 90 Hz screen will sometimes silently switch down to 60 Hz
One of the OnePlus 7 Pro's defining features and major selling points is its 90 Hz display. The extra-fast refresh rate allows for animations to be buttery smooth giving you a kind of a "soap opera effect" as you scroll through information. It's cool, it feels smooth and responsive, and it's still a rare feature to see on a phone.

But, wouldn't you know it, it seems you won't get to enjoy 90 Hz at all times even if you go into Settings and make sure that the 90 Hz option is checked. In fact, internally, OnePlus calls it "Auto 90 Hz" since the phone intelligently chooses when to use 60 Hz and when to go up to 90 Hz.

Put down the pitchforks, there's good reasoning behind this!

Reportedly, OnePlus will limit your display's refresh to 60 Hz when using the Phone app, the YouTube app, the Camera, or any large scale game. Because, in these scenarios, you don't really need the high refresh rate. The highest frame rate a YouTube can go to is 60 FPS, and most games are coded around 60 FPS as the ceiling. The Camera is also all about recording at 30 to 60 FPS. OnePlus found it appropriate to throttle the refresh rate in those instances just to shave down some of the battery usage and lighten the load for the hardware in general.

However, some browsers may also not run at 90 Hz, which may be a compatibility issue... and that's not cool.

You can enable "True 90 Hz" mode, which will force the display to stay at the higher refresh rate at all times. To do so, you need to connect your phone to the PC via cable and feel comfortable enough with running an ADB command. You can find all the info in the XDA report.

Very logical decisions. Why refresh at 90 frames and the content refreshes at 60?

This is old news and was reported almost as soon as the phone came out.

This is like asking for a display with 400 ppi when the average healthy human eye sees no more than 300 ppi.

Trying to justify the low-end screen on your Xr? Lol

That is only true for normal viewing distances, and for non-PenTile displays. You'll spot the difference the moment you take your phone closer to your eyes than you're supposed to. Mobile VR also needs the high resolution. A PenTile display has only two glowing points per pixel, so it takes a higher resolution to mask the effect.

Try telling to the heard of Apple haters who populate this site that a pentile display needs at least 465 ppi to be as sharp as the "low-end" screen of XR and see what happens :)).

Poor decision. Only Samsung have pure 90Hz screens.

Is that means screen throttle?

It's just being smarter/more efficient Why waste power doing 90Hz when the content is just 60/30/24 fps Apple do the same with Pro Motion on their iPad Pros

That's what that sounds like.

Something tells me this soo much noticeably smoother than 60hz is more placebo effect more than anything. If this is true that it's switched to and fro in certain applications and people were not made aware of it til this article, it only supports the claim.
