Windows 10: External Monitor scaling incorrect

I have a laptop connected to a docking station with two external monitors. I'm running Windows 10 v21H2 OS Build 19044, 1503.I have the scaling set up as "recommended":Laptop: 125%Ext. Monitor 1: 100%Ext. Monitor 2: 100%On Monday everything was displaying fine. I was jumping back and forth between the office and our shop - meaning between using the docking station and not. I was shutting down in between jumps. I noticed my laptop sometimes takes longer before the power LED goes off. So I may have closed it before it was completely off - I'm not sure.Monday night, .NET updated.Tuesday, s

External monitor is blurry

Hi,

The blurry display when using an external display may indicate a scaling issue. If the display of the internal monitor is not compatible with the external monitor, it may render a poor or fuzzy display. As an initial step, we suggest that you try the methods
under the Workaround section provided on this
support article.

Let us know should you need further assistance.

 

External monitor display settings

Hi,



Thank you for posting in Microsoft Community.



I understand that you are facing issues with the display scaling on your external displays. We will certainly look into this for you.

As you are using Vizio TV, you may have to try using custom resolution settings if the in-built settings do not provide the required settings.

For better clarity, please let us know:

• What is the version of Windows 10 that is currently installed on your computer? You can click on Search and type
  winver.
• Are you aware of any recent changes to the system, such as updates, after which you are facing this issue?
• What is the make and model of your computer?

Meanwhile, I would suggest you to check the steps mentioned in the Workaround section in

Windows scaling issues for high-DPI devices

I would also suggest you to check the Display drivers. Please refer

Let us know how it goes.

Dual-monitor scaling

Hi, everyone.

I have a laptop+external monitor setup. I use 125% scaling for laptop display and 100% for external monitor.

The problem is when I unplug monitor from laptop and later connect it, scaling factor for external monitor resets to laptop display value. So, every time I have to change scaling value manually.

I guess the issue caused by custom scaling. But I can't turn it off permanently. I have to turn it off and re-sign in every session.

So, summing up:

1. How to turn off custom scaling permanently?

2. How to fix scaling factor for external monitor?
