FWIW, i was having trouble reading the CMD window on my miners over Teamviewer while looking at the console. The font was too small and hard to read. What I found is that you can right click on the CMD window title bar, select properties and change the font and font size, background color etc. So now I have black text on white background and font size 20 and I can easily see what's happening! .
Pretty basic, but glad I finally googled it! Hope this helps someone else!
