Matlab R2014A blurry on high-dpi windows device

I'm running matlab on a 1080p 10" device, and i'm facing a few problems with the resolution of the windows. The whole window is blurry (check the attached images n°3 and n°5), and if i try to run for example simmechanics, matlab resizes the text in a way that each character is so small it's almost impossible to read (check the attached image n°4).
Since this makes matlab almost unusable, how may i fix this?

You might check to be sure you have the latest version of your video drivers.
There are no updates for my video drivers, but i don't think it would change anything.

This is fixed in R2014b (the general release, not the prerelease).

It seems like this is still a problem in R2014b (running on Windows 8.1 with a high-dpi display), and I can't find any mention of it being fixed in the release notes. Furthermore, Process Explorer still shows the MATLAB.exe process DPI Awareness is "Unaware".
How did you fix the problem with R2014b?

It is a problem of the auto-scaling of the application in Windows. Just right click the application symbol, and disable display scaling on high DPI settings. Here are some screenshots of how to do it: http://www.microsoftfanboys.com/2013/02/how-to-adjust-windows-8-display-settings-for-high-dpi-ppi-screens/

I'm currently running R2015a and the problem is not resolved yet, but this solution did the job. I should add that, when you right-click the application, you have to click 'Properties' and go to the 'Compatibility' tab. There you can check the box.
Thanks Brian :)
This worked for me too! Thanks Brian

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

This is the only solution that worked for my case! Im using Win 10 64bit, I had tried a lot of things but only the patch offered for "Bug Report ID 1054442" worked. Thanks a lot Bora!

I don't see anything blurry. What's blurry? Do you mean the folder names in the Current Folder panel being gray? That's just because those folders are not on the search path. Otherwise say what text or images are blurry and tell us if it's like that for other programs too.

No, everything is blurry and you'll notice it if you open the image at full size (just compare the timestamp on the bottom right, with anything inside matlab). And yes this happens with a few other programs too like Skype and some versions of windows installer.
I'll add a few images to show this problem in a better way.
Honestly it looks pretty sharp to me. But what that tells me is that the blur is not in the digital image, it must be in the display itself. You can only capture and save, from the device, the digital version. But the display may be blurring it upon display. If you took a photo of it with a handheld microscope and compare that to what it looks like in the screen capture, then there might be a difference.
Anyway, it looks like a device problem, not a MATLAB problem.
Ok, this is not a device problem since any device with a high-dpi display will have these problems: for more informations here: http://www.hanselman.com/blog/LivingAHighDPIDesktopLifestyleCanBePainful.aspx and here http://www.mathworks.it/matlabcentral/answers/102946-why-does-the-matlab-desktop-look-blurry-when-using-matlab-8-2-r2013b-on-my-mac-with-retina-display In the end this is Matlab fault, in particular the second part where it ignores Windows text size settings.

Two things did it for me: 1. go to matlab/bin and right click application, choose compatibility and check "disable scaling on high dpi" Now letters are very small in the editor. 2. Adjust font size under "file", "preferences"

Thanks Sargondjani, it really works for me.
the remaining problem is the font in the toolbar is really small, any idea?
Thanks
