No replies but after a day I've figured it out. I have a high resolution monitor (2K) and that seems to be the issue.
If anyone else has the problem:
1. Right click the speccy file.
2. Choose properties.
3. Choose Compatibility tab.
4. Check the box that says "Disable display scaling on high DPI settings".
This same setting has worked to fix iTunes and some other "blurry" programs as well.
