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

Anyone else have any experience with the Redmere cables ?

If you all don't use wall plates...how do you treat the hole in the wall where the cable enters and exits ? I don't want to just have a hole in the wall with a cable hanging out of it . The WAF thing ! Also not very energy efficient .

Thanks

Thank you for the info .

It appears that a good quality HDMI cable may suffice for the distance that I need .
Given the above info...I would like to know the opinion of using a 25' to 30' cable with wall plates . Will the wall plates and additional short HDMI cables on each end denegrate the signal . Will this set up suffice for 1080p
and 3D ?
Lastly , the Bluejean Series 1 cables have been recommended , these run in the low $100 range . Is there a better cable for less than $200 ?

Thank you

Ok... would cat5 work better with the wall plates ?
How futureproof is the Cat5 set up ?

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 .

Ok , thank you Internetmin . I appreciate the info and advice .
