I have a problem with blurry text when using an external monitor with my laptop.

My laptop scaling is set to 125% while the monitor is set to 100%. Both are 1920*1080, but when I extended my desktop (laptop = main, ext. monitor = secondary), the text in the 2nd monitor is blurry. Anyone know how to fix it?

i am using almost same setup with you
but my display 2 = monitor and is my main display

words no blurry at all

both screen 1920x1080

Sometimes it is due to the monitor recommended resolution.

I encounter the same, and the text is only clear(sharp) if i set the monitor separately. I.e different resolution for both.

Anyone have a solution?

For my case, 1080p is the native resolution on both display. Just that my laptop screen is smaller (laptop 13.3" vs monitor 24"), so need to scale it bigger for text to be legible.

don't think have one. Just set the resolution and scaling per individual monitor. At least that's how I set mine at work.

After trying further, I notice that this might only happen when I open the app in my main screen (laptop) and then move it to the ext monitor...

still experimenting on how to get this to work...
