Windows 10: Blurry on Monitor 2

Hi,

This is a clean Windows 10 installation.
OS: W10 Home
GPU driver: AMD Mobility Radeon HD 5000 Series
Monitor 2: Dell ST2410

This happens approx after 30 min. W10 has been installed.
Before, opening FF would be crystal clear, or any other application, for instance Skype, was clear too.

In order to replicate, I reformatted the system 3 times and it seems the change occurs when the attached message appears.
Regardless, whether you click Go or Close, the problem starts.

Settings in the AMD Panel are as they where before, nothing changed there.
In FF, changing the compatibility view to 'disable display scaling on high DPI setting' partially solves the problem, but it is not the solution because when you do it, the page shows bigger fonts, it looks zoomed to 110% (but it is not in the browser) while the text should stay as previously.

This must be a bug but so far, I was unable to find a clean fix on the internet.

Hope you can help.

Thank you
Alex

Dual monitors with different DPI settings do not give correct scaling

This is incorrect. Metro apps, file explorer, word 2013 are all blurry on the 1080p monitor. i just added a 4k monitor to my 3 monitor setup, the other 3 being 1080p monitors. the other 3 monitors are all blurry and scaled incorrectly.

 

Mixed resolution scaling results in blurry applications?

This looks to be a continuation of the bug described here: Multiple Display Scaling is Blurry.

I have the following monitor configuration:



Monitor #1 is UHD and is using 150% scaling. Everything that respects scaling looks great on that monitor. Monitors #2,#3,#4 are 1080p, 1080p and 1440p respectively, and are set to 100% scaling. The problem is that most things appear obviously blurry
on monitors #2,#3, and #4. Windows appears to be scaling everything on those monitors to 150%, then scaling back down to 100%. Any legacy dialogs and applications that don't respect scaling look perfect on monitors #2, #3 and #4.

If I take an application that does respect scaling (say Chrome or Edge), and place it on monitor #1, but overlap it a little bit onto the other monitors, the application looks scaled to 150% on those other monitors and does not appear blurry.



After fiddling around with connections, I'm convinced that it is not a hardware or driver issue, and that Windows is scaling, then descaling, the monitors I set to 100%, and the results are very poor. Is there any way to get Windows to simply *not* scale at
all on those monitors - to disable it entirely?

 

Hello Alex & welcome to the forums *Smile

Looking for the simplest explanation first. I wonder if Cleartype is getting turned off by the AMD software. Did you check this setting before and after the screen became blurry?

 

Hi,

Here is how I fixed it:

• Right click on Desktop -> Display Settings
• Advanced Display Settings -> Click the Monitor with the problem
• Advanced Sizing of Text and Other Items
• Set a custom scaling level
• I changed the percentage from 125% to 100%
• Problem solved, crystal clear display

Hope this helps

Hi there

another thing to look for also in future - in the Monitor HARDWARE controls - especially if using a TV type monitor - check that you haven't overset contrast, brightness or in particular the sharpness setting -- oversetting these will yield sometimes an absolutely HIDEOUS picture.

If there's a colour temp control too -- choose between Warm will sometimes yield white as "off cream", Cold - rather bluish type of colour and probably over bright white if you are doing a lot of Word / document editing, Film / cinema mode or Sport mode (I find that one the best compromise for TV / Movies and boring things like Office doc creation, email etc.

The modes won't always have the same name but you should see the functionality equivalents on most decent monitors / TV's.

Usually you need the Menu from the Monitors handset and not the computer.
