The VSD not starting issue is easy enough to fix. Find the shortcut you use to open VSD. Right click on it and choose the compatibility tab. At the bottom of that tab check the box for Run as Administrator and that should fix that issue. If it still persists try the same steps but also set it to Windows XP compatibility. Shouldn't have to the the XP part though.
What most people are talking about on the settings for your resolution is that it needs to be set to the 100% setting, making sure it's 100%. Size wise being the highest is not always the best, it is in most cases, but there are a few where this issue persists even if it doesn't seem like it should. Check your settings again and make sure it's at 100% and hopefully there's something there that will help.
