At Startup, Windows uses 150% scaling on 39" 1080p monitor.

chroma601 · 17 Aug 2022

I've been using the HDMI input of a 39" Insignia Roku TV set as a monitor. It's been flawless for some time, but lately (several months ago) it started randomly switching to 150% scaling, which looks awful. I go straight to Display settings and reset to 100% (Windows recommends 150%) and I'm good until the next boot or sign-in. It used to be random but now is happening regularly. Some dialog boxes remain at 150% (like the moving files context menus) but the graph of the move looks fine.

Is there any way I can tell Windows to leave my settings alone? Better yet, is there a way to troubleshoot whatever is causing this?

Skytech Blaze computer AMD Ryzen 5 1600 with Radeon RX580 graphics card running Windows 10 Home version 21H2. Windows Feature Experience Pack 120.2212.4180.0

Thanks for any help!

The normal procedures are
Change your DPI Scaling Level for Displays - TenForumsTutorials
Turn On or Off Fix Scaling for Apps that are Blurry - TenForumsTutorials
but it sounds like you are doing it correctly already.

Does SFC report any errors? SFC-DISM - TenForumsTutorials Option 3 is the normal choice.

Does your display card maker supply an updated driver? Personally, I'd reinstall the same one if a later one was not available just to bowl out driver corruption as a potential source of the problem.

Best of luck,

Happily, Windows Resource Protection did not find any integrity violations.

I've looked high and low for anyone else having this problem. All I've found are links to how to set up the scaling. But I have no idea why I have to do this every time I start up. Since it's an HDMI connection, I tried starting the monitor first, then booting. No help. I will look into the Radeon drivers but I'm thinking this is more of a Windows issue. Never hurts to try.

So I updated the drivers for the Radeon to the latest version, and upon first bootup everything came up correctly.

I will keep this open a few more bootups just to make sure this issue stays solved, but off to a good start.

This morning I started the PC and Windows came up at 150% scaling. So we can rule out the graphics drivers.
But it's a real PITA having to set it after most every bootup. Why won't Windows remember my settings?

An additional clue might be that every time this happens (or, most times) I am also required to resetup Clear Type.

Anyway, help would be appreciated.

I note my post has been moved to Graphic Cards. I'm not convinced about that.
