Well, now i have tested ZoomIt but I really can't see any difference from Windows magnifier. I run windows 10 on my laptop and I can't see the distortion you talk about either... It's not that the stream is crystal clear at 400% but good enough
Guys, guys... Windows has a feature called the magnifying glass. I have used it for a loooong time at rlc. You can magnify so you'll get much more than full screen :)
