So i bought an HDMI cable for my htc evo from Monoprice. As I plugged in the wire, it seemed to worked the fist few times. However, it was tough getting it to work correctly due to constantly losing connection. As i constantly unpluged and plugged the hdmi from the phone, thereafter it stopped working. I dont get any notifications what so ever. I wiggle the cable around to see if a bad connection is the culprit, however i get no luck. So I now try my relatives HTC evo with succesful results on the 1st try. So we now know the cable is not the cause of our problem. We both purchased the HTC evo the same day(2 weeks ago from today), so firmware and so forth should be the same, right! So should i exchange my HTC EVO for another one? I mean, i am allowed to do that according to sprints exchange policies right? Do i have a bad hdmi port? Please, advice and helpful pointers are highly appreciated.
