A:Answer In order to potentially resolve the fuzzy image, I recommend that you visit the computer manufacture's to download and install all updates for your computer. The most import updates to consider are: Chipset, Thunderbolt, BIOS, and Video Drivers.
Another things to check on is the refresh rate. Please make sure the refresh rate is set to a value that the display supports.
Lastly, I would recommend that, if you are are currently mirroring the display, change the display settings to "Extend these displays" under Windows Display Settings.
