I installed parallel dekstop 7 and a copy of windows 7 on my macbook pro 15 mid 2012. However, every time I want to watch movies on win7, it has really bad screen tearing at the most action pack scene in the movies. Screen tearing as you will see horizontal streaks on the monitor. I am sure the problems are not from the illegal copy of parallel desktop and windows7, because my housemate has exactly same version of parallel desktop and windows on his retina 13 inch and the movie playback experience is so nice, no screen tearing etc. just nice. I have done everything I could to try to solve the problems:
-I tried to reinstall the mac system (my mac shipped with lion 10.7.5) and the windows copy on parallel desktop
- I tried to change every little settings they have on the parallel desktop 7(ram, cpu, video memory etc)
-I searched on google and tried to find if someone out there has the same problem as i do(apparently everyone has great experience with their parallel desktop).
-The closest step for me to get rid of the screen tearing was to upgrade to mavericks. To be surprised, it worked. But it created another problem-there were green horizontal line at the top and bottom of the movie. (so if you consider the movie is a square box, the top and bottom length were marked with green horizontal lines).
I have tried everything for the last few days and I just can not find any solutions to my problem. Please, if anyone out here how to solve my issues it will be much appreciated .
P.S. One of my friend kept talking about its the hardware problem on my mac. HOW? i have the 2.7Ghz high end cpu and gt650m as my graphic card. My friend had a 13 inch retina without any dedicated graphic card and the movies playback on the parallel desktop is as smooth as hell...
oh almost forgot to mention that my macbook pro has 8gb ram. Both of mine and my housemate's laptop are playing the same movie with the same video software....
Thank you all in advanced. I am so tired of trying to fix the parallel desktop for the past few days.
