I have a 16 R and must say that I like R's resolution better then MDX's. You can improve it by playing with the settings. This is what I did:i thought it was hazy too. it's better than my 15 Golf R but that could be due to the low res screen i have in that car.
1- System Settings
2- Display
3- Brightness set to +11
4- Contrast set to +5
5- Black level set to -5
While it's not perfect but it is much better than what the default settings were.
