Why does the MATLAB desktop look blurry? Using monitor 2560x1440 and R2014a.

Dear Matlab users,

How to solve the blurryness of Matlab 2014a GUI runing on a W8 and using Dell monitor with 2560x1440 reolution (see the difference bw Matlab window and Corome behind it in attached printscreen)?

I read the solution for Mac with Retina display (wish was refered to in answers of the question "Matlab R2014B blurry on high-dpi windows device" - similar to mine).

But HOW should I make it work in W8??? Thanks for help in advance!

This blurriness is due to the scaling done by the operating system. You can try disabling the scaling for MATLAB which might help you resolving the issue. To disable scaling for MATLAB, right-click on the MATLAB icon and select"Properties". Then, under the "Compatibility"tab, select "Disable display scaling on high DPI settings".

It is possible that the text in MATLAB may become too small when display scaling is disabled. In that case you can increase the font size used by MATLAB. To increase the font size in MATLAB, open MATLAB R2014a, select the Home tab on the Toolstrip in MATLAB window and choose “Preferences”. Under “Preferences”, select “MATLAB” and choose the desired font and size from the “Fonts” tab.

You can refer to the following threads which deal with similar issues:

Debarati's solution worked for me. In my case, my secondary monitor had a higher scaling (150%) than my primary monitor, and MATLAB was very blurry on the secondary monitor.

Compatibility tab > "Change high DPI settings" > check the box "High DPI scaling override: Override high DPI scaling behavior. Scaling performed by: Application"

it did help! But it seems that the color has been changed

There is a workaround now available in R2015a release of MATLAB that partially resolves the issues with blurriness and resizing of the MATLAB Desktop on Windows platform. The workaround patch can be downloaded from Bug Report ID 1054442.

Hi,

I am running R2015a on a ubuntu, 2560x1440. The UI is really small!!

[Bora Eryilmaz]

Unfortunately, the workaround is currently for Windows systems only.

This works for me, thank you. I use R2015a on windows 10
