sx20 cant see presentation when using HDMI to DVI adapter

[NPatenaude885]

I am running ce 8.2.2 Final on the SX20. So initially I had this problem and after doing some research on the CSC I was able to figure out that I had to switch the input from auto detect to digital. After doing this my laptop was able to send content and I wrote this problem off as fixed. Fast forward  to yesterday and I bought a Display port to HDMI adapter so I could hook up one of the dell desktops that litter the room to the SX20(DisplayPort=>HDMI=>DVI). The SX20 was still set to digital and couldnt/wouldnt see the PC. I removed the DP to HDMI adapter and plugged the HDMI into my laptop and again nothing. Now Im really confused because this was working fine a few months ago. This unit is installed in a cancer center and all the cables are ran through the walls and the sx20 is behind the huge wall mounted NEC screen. I will check under the peripherals tab next week while sending a good signal to troubleshoot.  I did the basics of changing resolutions and machines to attempt to narrow down the issue. Any other ideas on why this would all of a sudden not work.

So when you try to present content, do you see a black box where it should appear? Is the SX20 configured as a single or dual screen system?
SX20 comes with a DVI to HDMI cable, or if you have one around, try connecting it to the SX20 and to an HDMI capable laptop. The cables between the SX20 and laptop or a combination of the adapters could be the issue.
Another possibility is that the configuration changed on the codec.

For anyone who has this problem the fix is pretty simple or at least this version of the issue was. I wasn't convinced that it was the HDMI to DVI adapter because it was working initially, but after it was swapped out with a different one it worked flawless
