So I recently bought a Dell Latitude E5550 with a 1080p Touchscreen, and I'm having issues with it. The touchscreen cuts in and out, and to get it working I have to bend the screen or hit it for it to work. I suspect it's an issue with the connection to the touch digitizer and the motherboard. Does the touchscreen go through the E-DP cable? Or is there a different connection for the touchscreen, because It seems like an issue with the E-DP cable, if the touchscreen goes through it.
