Evening, I've tried 2 Intek Cat 5 extenders over the past couple of weeks with disappointing results.The first was across a run of some 25m to a Pioneer LX508. Nothing, not a sausage...the input signal flashed up regularly, indicating the input could see something, but it didn't materialise into a pic of any sort.
Dropping to 1080i made no difference.
The Cat 5's were run and terminated by me...interestingly, across the same pair of Cat 5 cables via a Kramer VGA/Cat5 extender I can get fantastic analogue RGB at 1440 x 900.

The 2nd attempt to an identical Pioneer 50" (otherwise unrelated to the first attempt) over approx 18m distance produced no result at 1080p (although I had the flashing input on screen again) however, reducing the res to 1080i produced  a nice pic (albeit at 1080i)
Again cables run and term'd by moi, very confident they're not at fault.

Alas, in both cases, there were 2x full HD displays to drive and I was really counting on the exender to get a 1080 signal to the second display. Even in the case of the sucessful 1080i pic, it was nothing other than exceptionally frustrating because of course it meant feeding the main display a 1080i signal also, unacceptable in my view.

As an aside, I have had sucess with both the 2 in/1 out "auto sensing" switchers I have integrated recently (they were powered).
However a similar product purchased from Jaycar - non auto-sensing  was an utter fiasco.

Introducing such add on's to HDMI appears to still be somewhat hit and miss.

Cheers

Thanks, will order these in the morning and hopefully I get a good result as you have. I'm gonna need to get some cat6 cable, but will try with cat5e first and see what happens, would prefer not to have to run the 25m through the roof again (such a mission).

I must mention that with all my previous tests I have attempted to drop the sky hdi to the lowest possible resolution, 574 or something like that, I know it's in the 5xx range, also tried 720, all with no picture at all.

thanks
