Hi,

So, I've been using my LG42 LH4000 with my LG22", and ATI HIS HD4850, in the begning I could clone the picture, via CCC, just fine, had no issues with it, whatsoever, the sound worked well aswell. Later I only used the LG42" to play with, and didnt have the 22" plugged in at all. Still, it worked fine.

But... When I put the PC back, and hooked the 22" in again, the compture cannot find the 42" HDTV anymore, it cant detect it. Now, I've tried using another graphic card, still doesnt work. Tried renewing the drivers, still doesnt work. I've tried reinstalling windows, still doesnt work.

I'm about the test if it's something wrong with the cable, my cable a 10meter HDMI cable, with a ATI DVI-HDMI adapter insert into the graphic card.

Would love you hear if anyone of you could assist me in this frustraiting problem. It just seems wierd, it worked flawlessly before.

Thank in advance,
DKL.
 

I don't have any other HDMI devices to test, atm, I could borrow though. The TV does not have DVI input, it does however have a RGB input, I also tested with a S-Video kabel which successfully detected the monitor, but not through the HDMI.

I've also tested with a new HDMI cable, which is 1m so there's nothing wrong with the cable.
 

You can test with another PC or Laptop with DVI/HDMI, if it still doesn't work check your TV settings
