HDMI cable length...how long is too long ?


I am planning a new HT/Audio installation . I want to know if there is any negatives to using long HDMI cables . I am planning to put about 24ft. of cable between 2 wall plates . Then short HDMI cables to connect the source to one wall plate location and the TV to the other wall plate location . In effect the TV is on one side of the room and the sources are on the other side .

Thank You

I like those wall plates that were in the links , thank you .

I'm still undecided whether to use the suggested HDMI cables or to use cat 5/6 cables instead . Are there any futureproof advantages of one over the other ? That would probably be the deciding factor .

Thank you .
I strongly suggest running both. However, for your purposes, I'd simply use the HDMI cables for now and then if you run into problems look to use a BALUN on the Cat6 cabling. Rule of thumb: You always want a home run to eliminate points of failure. The Balun is great, but unless you need to use it, I'd stick with the HDMI runs with quality cables
