I have a predator Z35 I am using the cord that came with the screen. I have had the screen for about 6 months. The display port is getting really loose. It started out that if I moved the screens height the screen loose signal and convert the main display to my other screen. I would have to move the cable to get the Z35 to turn back on. Now it has gotten to the point that if I just bump my desk the screen loses signal. then have to move the cable to get it to work. Has there been any other problems with this, also is there a fix for this or should I just contact the warranty department?
