Hi guys!

So I've bought myself a Dell U2515h, and I love it (tho I do have to adjust to everything being so small xD). My 'old' monitor is U2412m.

Now the new monitor is 2560x1440 and old one is 1920x1200. Both are connected with DP cabels to my GTX 960, and I extended the desktop.

The problem is that my new monitor is nice and crisp, while my old monitor is totally blurry all of the sudden. And it wasn't that way before.

I googled a bit, but didn't find anything useful.

I found that I can set, and on every program (which is a pain in the butt), in the compatibility settings in the properties: 'Disable display scaling on high DPI settings'. But what this does is just makes everything big on my old monitor :S This fixes the blurring issue, but only for that program. My properties dialogue box is still blurry :S

Is the only workaround this to have 2 screens of the same resolution?

I'll have to wait a bit until I buy second u2515h monitor (they're pretty pricey).

maybe the card/driver fucks up when 2 dp monitors are connected. tried dvi on the old one? should work as fine as dp cause its only 1920x1200@60hz

I use HDMI on my main and DVI on my second as if you switch off the monitor with DP it makes the other one primary Reaction


PC: Yes. Console: No.

Didn't try to connect it alone and on other device. I'll test that tomorrow, I had tons of work to do.

thats the only thing to do, test it, exclude failure caused of different parts and if nothing is left to change -> display defect

and try to reset the device itself with the osd

I assume you have checked the resolution and refresh rate on the monitor when it's blurry?
Some scaling due to non-native resolution is about the only thing I can think of for it to become blurry if it's not a hardware fault.

Generally speaking, you should have no issues with using two monitors like that.

Yeah, resolutions on both monitors are native, and refresh rate are 60Hz. I'll google more a bit to see what could be the issue.

Rub vasaline on your left eye, then they will both look the same (or you could boot a live cc and see if it's hardware or software)

So apparently windows is stupid -.-"

http://superuser.com/questions/948758/windows-10-default-dpi-settings-make-cmd-blurry?answertab=votes#tab-top

I put that in the startup, and restarted and now everything is crisper on the old monitor.

I think I know what the issue is. The monitor picks up the dpi scaling from the new monitor, and tries to preserve that value on the old one, and it makes it blurry.

Well all is well now, and I didn't have to rub my eyes with vaseline grinhurt

windows 10 is finally able to manage the dpi settings for more than one display differently -> so i didnt even thought about that as the failure source... strange thing, but glad you found the solution
