I just got the RGCHD and installed the software. I hooked up my Xbox 360 to the device using HDMI cords, and while the picture on my Laptop is fine, the picture on the TV is not.
The picture on the TV keeps flickering in and out. While it was flickering, I made sure my Console settings were on 720p/1080i, since it does not support 1080p. Still glitchy.
Then I decided to take it out to the front room (where I rarely get to the tv out there) and sure enough, it works on that TV, which is newer than the one I have in my room (Mine is an Olevia, not sure which model, One in living room is a Vizio)
Furthermore, Component cords work on both my tv and FR tv.
Edit: Olevia is like 6/7 year old
Could it just be because of HDCP? Or is there something else it could be?
