I have a graphics card with one HDMI port and one DVI port. To get the best resolution to my monitor (where I do my primary work), I'm using HDMI to HDMI. To get signal to my TV (second monitor), I'm using a DVI-to-HDMI cable from the computer, then I have an unpowered HDMI connector that I'm using to join the two cables together. (The DVI-to-HDMI cable is too short to run directly.) The computer detects the connection (even tells me that it's DVI, so I need another cable to run sound, etc..,) and it shows up when I do my display identification. However the TV itself says "no input" and shows nothing.
I know the DVI-to-HDMI worked with my monitor. At this point I'm wondering what SHOULD work. Is there a known issue going DVI to HDMI on a TV? Could the problem be the unpowered connector?
I had the DVI-to-HDMI running to my monitor initially, but something was telling me that the DVI wasn't giving me quite as good a picture as the pure HDMI connection was. Part of it is that the DVI is a DVI-D, whereas the port is a DVI-I.
I just want to know if the set up should work, and I'm looking at some baffling problem with no solution, or if I need a powered HDMI connector, or if connectors screw up DVI-to-HDMI channels.
You might have to download some drivers, but that is very unlikely. The problem is probably you DVI-HDMI Cable, check if it works on another monitor or something and see if the cable is faulty.
Thank you for your reply! I appreciate it. The cable does work. I initially had it running to my monitor, and it worked fine. The only real difference is that I'm having to use a connector to join that cable to a pure HDMI cable so I can get it to the TV.
I have an update. I tried connecting the TV with just the DVI-to-HDMI cable (with no extension), and it worked. So now I don't know if the problem is the unpowered connector, or the fact that I'm trying to connect a DVI/HDMI hybrid cable with an HDMI/HDMI cable period.
