I already have 2 screens on my PC. 24" (1920x1080) and 22" (1680x1050). I wanted to connect my PC to TV. I bought a DVI splitter and connected it on the 24" DVI port.

connect PC -> TV : working
connect PC -> monitor : working
connect PC -> DVI splitter -> TV and monitor : NOT working

I don't know what's the problem, but I noticed that when I use the splitter my PC don't do anything, it's like when nothing is plugged :(

This is what my splitter looks like : http://www.computercableinc.com/ccinc/images/Splitter-Cable-DVI-D-MF-HDMI-F-Startech.jpg

Watch Question

1) Plug Monitor 1 into Splitter
2) ( Leave TV Unplugged from splitter)
3) Ensure PC Powered off
4) Plug Splitter into the FIRST port of the FIRST video card. Some machines have issues with multiple displays on single ports.
5) Plug Monitor 2 into port 2 / video card 2 of pc
6) Turn pc on.

You should at this point still be able to use both monitors.
If it doesn't work, power down, and switch the splitter and monitor 2 cables from  your pc.

Once you get both monitors working with the splitter, plug the hdmi cable into the splitter from your tv in and turn the tv on.  Ensure that the tv is tuned to use the hdmi 1 or whicher hdmi input you use. This may sound patronizing, but ensure that you are using HDMI INPUT X from your tv, as this is the cable sending data into your television.

It seems like you have tried most of this already, but keep these points in mind and you may very well get it all working.

If the above doesnt work, and you can get any monitor working when you go through the splitter, you may have a bad splitter. Note that using the splitter will not give you 3 monitors, but will mirror monitor 1 (the monitor sharing the port).

Do either the TV or PC monitor work when only one is plugged into the DVI splitter?

Not, I read the splitter must be connect to both OUT to work

As I said before, normally splitter can only be use when all monitors are connected so, at this step it will never work :/

ho and "[b]Note that using the splitter will not give you 3 monitors, but will mirror monitor 1 (the monitor sharing the port).[/b]" => it's what I'm expecting (watch HD films from my PC to my TV ^^)

Commented:
Just to start diagnosing the problem, can you drop down the resolution on your monitor to 1024x768 (or lower).  It may be the high frequency from the PC throwing it off.

I can't change resolution. As I said in my question when I use the splitter it's like when nothing is connected.

My PC tells me that only 1 monitor is connected (the secondary in fact)

Commented:
Change and set the resolution on your PC before you plug the splitter in.  Shut the pc down, then plug in the splitter with both connected.

Just read this about it on another site:
- When connecting this cable, be sure to connect the source (that is your PC) before the display components(your TV) to ensure a successful handshake between your components.

So, PC first, then the TV...

OK this is what I tried :

1] plug in first PC then TV (PC shutdown)
2] plug in first PC then TV (PC booting => low res)
3] 1 & 2 with low and normal resolution
4] 1 / 2 / 3 on both DVI port
5] 1 / 2 / 3 / 4 on the 3 HDMI of my TV

I think I bought a bad splitter.... it's a good resume of my lucky life >.<

or maybe someone have another idea ?
