My projector was working well with connecting through HDMI cable with my computer but not my xbox, so I got a new, higher quality HDMI cable. Now the projector wont connect with either my computer or xbox with either of the cables... VGA and video are still good, however...
Any ideas of what could be wrong?
Both HDMI cables work.
EDIT: now hdmi works with laptop, still no luck with xbox
What lengths are the HDMI cables and what gauge of cable?
I connect them directly. The Xbox connects HDMI to the tv, but not the computer. I've changed the input on the projector manually but it doesn't detect the xbox. The xbox connects through RCA to the projector fine, but the quality is not as good as it would be with the HDMI.
It is pretty frustrating.
While a long run HDMI cable is prone to potential issues, a direct one to one connection usually indicates a problem that is with the components, not the cable. If you've used the same cable with the TV and it doesn't work only with the projector, then the error tends to lean towards the projector.
I will say: I had a Denon 3313CI which did not work with HDMI at all when I got it. I did a firmware update on it, and nothing else, and then the video passed through the Denon perfectly. So, firmware updates can (sometimes) resolve these types of issues.
You can always try a heavier gauge HDMI cable from Monoprice or get a Redmere cable to see if that corrects the issue, but it doesn't seem like anything more than a projector issue. Unfortunately, this could be a problem with the HDMI board, or even the resolution or something else.
I would recommend you drop the resolution to 1080i or 720p signal instead of 1080p as that may (!!!) correct for the issues you have been experiencing.
You can force the Xbox to go reset to its default settings and hopefully will regain an image and can then adjust to best suit the Projector - http://support.xbox.com/en-US/xbox-360/settings-and-initial-setup/image-on-your-tv-is-unclear
