So I had a guy run a 35ft HDMI cable in mt HT room and I'm trying to find info if longer length HDMI cables can be 1.3a or 1.3b rated.

The cable is a Kanto Installer Series cable, 24awg, CL3 and FT4, and 'rated for 1080p'

I emailed Kanto and the guy that installed the cable and got conflicting responses:

HDMI v1.3 cable is designed to pass 340MHz (up to 1600p) which includes 1080p at 165MHz. All our long length cables pass 1080P.


You can not get a HDMI cable "Certified" from a lab with a 1.3 certificate at lengths 35ft and over. See Monster Cable own explanation of this on their website for cables 35ft and over (see bottom of page) http://www.monstercable.com/productdisplay.asp?pin=3831



Kanto 35feet is 1.3 at 16bit
It also passed the monster 1080p


Starting to dislike the installer after his shoddy install and stating things without sources

I understand if the cable doesn't get the 1.3 rating because it wont do 1600p but does that mean it would do deep color?

I will be running 2 cat6 cables to projector though for future hdmi extender use

You can certainly support 1080P 8 bit video on a 35' cable (do not know about Kanto). But I do not think that you will get 16 bit from one that long (verify with Kurt from BJC about his Beldon based cable) and if it will (again I do not think so) it will not be cheap.
The A & B ratings (at least in reference to cable) refer to the test procedure not the performance.
When looking at cable certifications look for:
1.3 cat-1 (2.64G total bandwidth) this will support 1080i.
or
1.3 cat-2 (10.2G total bandwidth) this will support 1080P 16 bit video.
It should be noted that the original HDMI 1.0 spec called for a 5G total bandwidth which will support 1080P 8 bit video.

Thanks for the info Brent.

I guess I'll stick with it and in the future get a cat5/6 extender as more content becomes available that uses what v1.3 has.
