Display issues with Cadence and 4K monitors

soll

Hello

I have recently switched to a 4K monitor and I have a lot of compatibility issues with Cadence software suite. By default, all the softwares are blurry, so I go to the properties > compatibility > scaling on high DPI settings. For all the softwares I use, the problem is solved by this action. With Cadence softwares... The result is completely random. I have no problems with Allegro 17.2 and Allegro 17.4 (the icons are a bit small, but OK)

OrCAD Capture 17.4 :
All the icons are overlapping themselves.
Text size is normal.
The software is unusable as is.

Allegro 16.6 :
All icons and texts are incredibly small... I just can't use the software as is. Strangely, the text from the menus isn't affected (text like File, Edit, View...)
By the way I don't have the tbiconsize in my preferences... Don't know why...

I tried setting the ALLEGRO_HIGH_DPI_ENABLED environment variable which didn't do anything at all. I searched everywhere in the User Pref menus, found nothing.
Does anyone found a workaround ? Is there a config I am missing ?
I find that quite astonishing that the only software that has problems using high resolution display is... a CAD software... :p

Thank you !

    Hi, maybe try taking a look at that windows system variable again.

    To set an OS level System variable go to Control Panel > System, then click "Advanced System Settings"

    Click the button "Environment Variables"

    There are two possible options to add that are a user variable and a system variable. You need to use a system variable as this would be applied to the OS.

    Add in a new system variable.

    The variable name is  ALLEGRO_HIGH_DPI_ENABLED 

    The value is 1.

    Save that and reboot your system. See if the 4K scaling works better now.

    Just a note on this. Alot of monitors do support 4K today, but unless you are using a really massive monitor like a 50 Inch or something similar there is no advantage to using 4K.
    What size monitor are you using ?.

    Hello and thank you very much for the detailed answer.

    I did that but unfortunately it didn't changed anything to the problem. I will try contacting the support from our local Cadence distributor.
    I figured that I am not using the latest update, maybe that will make things better.

    The monitor is 27". To be honest I don't really care about the fact that it is 4K or not, but it is a great improvement compared to the HD display I was using before. Allegro looks way better now, all the details look better, especially when I zoom out, I can still see component without having to zoom in again. Circles (vias, PTH...) keep looking like actual circles when I zoom out, which was not at all the case before. The only problems are the menus...
