I recently purchased a 4K monitor, and am loving it, but it has created a lot of issues for more secondary monitor.
Primary: 2160p 150% scaling
Secondary: 1080p 100% scaling.
I know this is a common complaint, but I have actually had zero display scaling issues on my primary monitor. Pretty much every program I use works acceptably, and the same goes for my Toshiba 12" 4k laptop which I scale at a whopping 250%
No, my problem is that once I set my 4k monitor to a higher DPI, it blurs all of my secondary monitors. I believe this to be because Windows actually scales all of the monitors to the DPI scale of the primary monitor, and then dials back the scaling for the secondary monitors until it matches what they're set to (100%), and this process isn't accurate enough, which ends up creating a slightly off image scale for the secondary monitors.
Here's an image I created describing it:
(in case you want a closer look: https://i.imgur.com/ZExbxTS.png)
Blurry refers to the primary at 150%, secondary at 100%.
Sharp refers to all monitors being 100%, no scaling.
It's not just the text either, every image has the slight blur to it. ClearType is not the solution here.
Even in Windows 10, Microsoft have not even come close to creating an acceptable Per-Monitor DPI scale.
I would love to know if anybody else out there in the community has had to fight this, and what sorts of workarounds or fixes they use.
I know most of this community uses multiple displays, and many of us have or are planning on getting higher resolution screens, and having a collective solution for everyone would make Windows just a bit more bearable with mixed resolution monitors.
The way it is now, my secondary 1080p looks like a standard definition television picture signal quality someone lives with when they're too stubborn to fork over more money for HD.
I forked over the money Microsoft, where'd my sharp picture go?
Thanks Everyone! Spread the word!
