2560 x 1440 resolution / dpi problem in Chrome

I'm having some issues with a 32" 2560 x 1440 monitor. Intel i5 with HD 5500 video chip. Edit: Fuzzy images. text not sharp. My monitor shows 2k in System Settings/Display, but when I go to it shows 1969 x 1107 instead.

Thanks to @AlexP for the direction. And this site for the answer.

The problem turns out to be Chrome's scaling.

To permanently get back to the nice, calming original scaling factor (=1), you need to edit Chrome's desktop file:

sudo nano /usr/share/applications/google-chrome.desktop

Find the line which contains the path to the binary and change it from

Exec=/usr/bin/google-chrome-stable %U

to

Exec=/usr/bin/google-chrome-stable --force-device-scale-factor=1 %U

Save the file (in nano: type Ctrl+X and confirm with Y) then restart Chrome.

No more eyes bleeding. :)
