One user bought a new laptop and he has a 4k screen resolution (3840 x 2160). This was causing problems because SaT's visualize grid was showing much smaller slots than the table size that he originally chose.
Here are the things we used to get things working:
1. We used 150% scaling within Windows. When we tried a custom 200% we found that that the text would get too jumbled.
2. For all pokersites, find the shortcut that you use to open the poker client. For example, if you open up PokerStars by clicking the PokerStars shortcut file on your Desktop, then thats what you will need. Right click that shortcut icon, and then select 'Properties'. Then click the tab 'Compatibility'. Then click 'Disable display scaling on high DPI settings' and hit 'Apply'. Then, simply Remove and re-Include the site within SaT, and see if that works.
