Dvi To HDmi Over CAT5E Mini Extender Review

Average Reviews:

(More customer reviews)I have finished trying out the DVI extender I bought. What I have is Windows 7 running on a Nvidia GeForce 9400 GT video card. The 9400 has a DVI output as well as VGA to my Dell SP2208WFP monitor. The monitor's native res. is 1680 x 1050 which I use. I bought fifty feet of CAT6 wire to use and I already had a DVI to HDMI 25' cable as my standard.
Using the 25' cable, my nvidia control panel see my TV set as a Zoran HDMI TV and set the res. to 1080i or 1920 x 1080 @ 30Hz. Picture is solid with good color. Looks just like my dell monitor. When I switch to the DVI extender using the CAT6 50' wire, the nvidia control panel see the DVI extender as a DVI extender. The control panel shows the max res. at 720i. I can manually load more resolutions along with their frequencies (refresh rates) but they don't work. Nothing shows on the TV with the other rates and resolutions. They range from 29Hz to 60hz at different resolutions. I have tried them all. And really the 720i does not work because there are color sparkles on the screen, so the picture is unusable and unwatchable. To get true solid color I have to switch to 480i.
I do realize that to be real fair to the DVI extender I should have used a 25' cat 6 cable but the box does say it will work at a range to 130' or 80'. I will try to sell it but I can't list it as the company did because as far as I can tell the extender does not work at its printed specifications.

So that is my report. Thanks for asking about my experience with the SIIG DVI to HDMI cat6 extender. I don't recommend it for High Def. pictures.
Aloha.

StarTech.com COMPUTPEXTA Composite Video Extender over Cat 5 with Audio Review

Average Reviews:

(More customer reviews)I used this pair of adapters to carry composite video out of a camera and audio out of a mixer, to a TV some 100 yards away. I was pleasantly surprised to see almost no signal degradation. Sound and picture came loud and clear. It's pretty amazing how well this product works, considering it's a passive device (no power required!) at low cost.
Note that the signal remains analog the whole way, this is not an ethernet signal, so don't think about connecting it to a hub/switch or computer! The little wire pairs inside the ethernet cable are used to carry the analog signals (one pair for the video, one pair for the right channel audio, and one pair for the left channel audio). The audio connectors are RCA, but the video is a BNC connector. I would have preferred it to be RCA as well, however the product does come with 2 BNC/RCA adapters so it's not a problem.
Here are the specs stated in the manual:
Certifications (Regulatory etc.): FCC, CE, WEEE, RoHS
Input: 1 x RJ45
1 x Stereo Audio RCA
1 x BNC female
Output: 1 x RJ45
1 x Stereo Audio RCA
1 x BNC female
Dimensions (LxWxH): 110 x 77 x 24mm
Weight: 460g (1.014 lb)
Maximum Resolution: 480i/480p
