Honored ContributorUsing Quartus with 4k diaplays
Hello,
The schematics on 4K displays are corrupted (please, see snapshot in attachment). Does exist some workaround ? Thanks in advance. PavelForum Discussion

Altera_ForumHi, I was able to fix my scaling for Quartus II as well as the Nios II Eclipse SBT. I have a 4K Surface Pro 4 with two 1K monitors attached.
The problem is that the application telling windows it will manage it's own scaling but fails to do so in mixed 4K/1K environments. What you can create your own manifests and tell windows to accept them: http://winaero.com/blog/how-to-fix-apps-that-look-small-on-high-dpi-and-high-resolution-displays/ The following are the manifests I copied and pasted to in order to help with my workflow (Quartus, Eclipse, Megawizard for custom IP, java): C:\altera_lite\16.0\quartus\bin64\jre64\bin\java.exe.manifest C:\altera_lite\16.0\quartus\bin64\jre64\bin\javaw.exe.manifest C:\altera_lite\16.0\quartus\bin64\qmega_ramq.exe.manifest C:\altera_lite\16.0\nios2eds\bin\eclipse-nios2.exe.manifest C:\altera_lite\16.0\quartus\bin64\quartus.exe.manifest ***Be sure to read through the link above. You must set a windows registry key as specified AND copy the manifest XML file in the same directory. Please rep if you find helpful =)- Altera_Forum
I'm not aware of creating manifests, but have searched a little ...
Here is short resume of what I understood.- Manifest is a specific object that inform Windows how to handle program when it is started
- Manifests can be incorporated in .exe or in .dll. But also (I presume it's my case) can be written in .xml files
- When last option is selected, a .xml manifest file is named like this: application_name.exe.manifest and must be located in the same directory as application_name.exe.
- In order to take into account high dpi issue, the option dpiaware is used in manifest file.

I followed every step but still can't make the block diagram look normal (or readable). Please see the attached pic.
Can any one help me to solve this issue?
(Hello Intel, 4k monitor is not a new technology, not like 10nm/7nm chip, so please try to update and solve this mess....)

This seem a dpi problem

Thanks, but how to resolve it ?
I've tried to reduce font size, also change screen resolution to SVGA (instead of 3840x2160) ... but without success. The appearance of blocks on block diagram remains the same. - Altera_Forum--- Quote Start --- Thanks, but how to resolve it ?

Ok,
Now it's a little bit better: I checked "Disable display scaling on high DPI settings" (snapshot below). But appearance is still mediocre: different inscriptions are superposed (snapshot below). When I try to edit symbol it seems to be unrealizable: either objects are can't be dragged, either theirs movements are unpredictable. https://s17.postimg.org/9pfai4qcr/quartus_schematic_4k_display_lunch_properties.jpg (https://postimg.org/image/9pfai4qcr/) https://s18.postimg.org/jcaazmvtx/quartus_schematic_4k_display_1.jpg (https://postimg.org/image/jcaazmvtx/) - Altera_Forum--- Quote Start --- Ok, Now it's a little bit better: I checked "Disable display scaling on high DPI settings" (snapshot below).

If you create and enable an external manifest, it will render perfectly. This helps tremendously with other programs too (at least for me). Not as difficult as it seems. If you try it, let us know if it works for you as well.

Thanks. --- Quote End --- Yep! Works like a charm. You simply place the file ~/quartus.exe.manifest in the same folder as the program file. (I'll be home later today and can check the proper file name). That is what would be called the manifest. It's an xml file. One thing you have to do is set the registry key to enable it though. After you enable it, you can make a manifest for any program that has high dpi problems The registry key and contents of the *.manifest file needed are in my link above.<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3" > <asmv3:application> <asmv3:windowsSettings xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings"> <dpiAware>true</dpiAware> </asmv3:windowsSettings> </asmv3:application> </assembly> - Altera_Forum
I've just tried it.
Nothing changed ... although I didn't add registry key. Can you suggest me the name and value. Thanks.
