Currently I have HDMI going through 2 lines of 30-40ft of Cat5e using a HDMI balun. I can get 1920x1080 @ 24hz or 1280x720 @ 60hz. If set at 24hz, my GoPro videos do not play correctly because they are shot in 30hz. If I try 1920x1080 @ 60hz, I get purple pixely blobs on the screen. I am guessing my balun or Cat5e can't handle the bandwidth needed for 1080 @ 60hz.

Has anyone been successful in getting 1080 @ 60hz through a balun or 2 strands of Cat5e?

Thanks!

I believe that cat5e is rated for gigabit speed on a 100m run. I don't know exactly what the bitrate of your 1080p60 source is but I know it is nowhere near gigabit speeds. So I highly doubt that the cable is your issue unless it is defective or you installed it incorrectly.

You are thinking of a compressed signal. When it is being sent to the TV it will be uncompressed so a much higher bandwidth than you are thinking.

Quote:Q. What is the difference between a “Standard” HDMI cable and a “High-Speed” HDMI cable?
Recently, HDMI Licensing, LLC announced that cables would be tested as Standard or High-Speed cables.

Standard (or “category 1” HDMI cables have been tested to perform at speeds of 75Mhz or up to 2.25Gbps, which is the equivalent of a 720p/1080i signal.
High Speed (or “category 2” HDMI cables have been tested to perform at speeds of 340Mhz or up to 10.2Gbps, which is the highest bandwidth currently available over an HDMI cable and can successfully handle 1080p signals including those at increased color depths and/or increased refresh rates from the Source. High-Speed cables are also able to accommodate higher resolution displays, such as WQXGA cinema monitors (resolution of 2560 x 1600).

Nowhere near gigabit speeds? 1080p at 60 hertz is about 950 megabit per second per color, and that's just for the pixels.

I'm using a 15 meter hdmi cable from könig which can handle 1080p at 60 hertz, sounds like a better solution than using cat5e.

The OP probably can't get into the ceiling to run a HDMI cable. If it is at all possible, it's well worth it. Baluns are hit or miss. Long HDMI cables are reasonably affordable these days.

My house is now entirely finished. When I finished the TV room in the basement a few years ago, I didn't have anything HDMI and did not foresee when I would. But I ran a bunch of Cat5e there.

I have thought about running HDMI through the outside wall, under the vinyl siding to the basement but the run would be extremely long.

Either way, the above posts explains it. Thanks!
