Collectible Card Game Headquarters

Hi all, I got a newbie question...
How do I change font size or resolution of Forge?
I don't want to change the system resolution though, actually I tried and it did not solve the problem. My Forge fonts are way too small...
I'm using win10, system resolution is 2736x1824.
Forge recommends 1024x768, tried and the font size are still super small...
Please help me...

Guys, I have solved the problem. So if anybody have the same issue, try this:
in your system display settings, select 300% for 'change the texts, apps and other items'.
I'm using a surface pro with resolution 2736*1824 recommended, the display use 200% for the size by default. Changing it to 300% solve the problem in Forge.
