Windows 10: Intel "panel self-refresh" indicator ?

Hi all, I'm trying to figure out how my laptop's display actually works; it features a 144hz panel, and that's the only refresh rate available in any setting I could find, even creating a custom resolution with a lower refresh rate in the Intel Graphics Control Panel is not possible; I'm NOT here to talk about this though.


Since mine is a Nvidia optimus laptop, all the display management is kinda weird, though I found what may be a really cool feature in the IGCP: it's called "panel self-refresh" and it seems to adjust the display's framerate automagically to save power. The description is rather confusing and it's all I was able to find about it. It may just control the outputframerate of the iGPU which is the display adapter or the actual refresh rate of the display's panel, which would also kinda explain why there is only one available and nothing else is possible.


SO, I'd like to ask if there's any program that displays the panel's refresh rate to see what's actually happening.

I've already tried the UFO test website but it acts kinda weird, so as I unplug the laptop it becomes unable to vsync probably it's measuring the GPU output with vsync and not the actual refresh rate.


It was a rather long post for a pretty short question but heh, context.


Thanks in advance to whoever will help :·

I can't disable 'Panel Self-Refresh' setting in Intel graphics control panel

When I open my Intel HD Graphics 630 control panel and go to the power section I don't find the Panel Self-Refresh setting. It's hidden in someway I think and I don't know whether this is about Windows 10 Education v1709 I currently have or about HP's
OEM or Intel's generic drivers as I tried both of them and I still can't find the setting but I really need to disable it due to some screen freeze problems.

 

I can't disable 'Panel Self-Refresh' setting in Intel graphics control panel

Hello
punleashed,



This issue is probably related to your graphics driver. Others have also reported this concern that the Panel Self-Refresh is causing their screen to flicker and freeze. In that case, we would recommend you to
install the Intel HD drivers from your device manufacturer’s website and install them directly through the device manager. You will get access to Intel driver’s settings GUI, just right-click on your desktop or check your
taskbar after completing the install. In the settings, go to “Power” and from there disable PSR. If you’re still having issues with disabling it, we highly recommend that you contact your device manufacturer for advanced assistance with the settings as they
have more familiarity with the GUI of your device.



Feel free to get back to us should you have other concerns.
