I have a Hisense pulse, which does not detect the correct display resolution for my projector. It is connected through my audio receiver (as are 4 other devices, which all work fine). I did find the resolution settings, but when I go there, it only shows "480P (Auto)" and will not give any other options. What I need to display is 720P. Is there some way to disable auto-detection and get all the options to manually choose?
