I'm not too sure how much better the 1080 is compared to the 720, but it is
You see very shortly i'll get my system sorted as i want it & unfortunately this will result in an 8M HDMI run from an Octava HDMI switcher in my rack to the TV... There will be a 5M run from the Octava to my projector.
As soon as i received the 8M run of 1080 cable i naturally connected it up to try it out, again there were no problems unlike other HDMI cables the didn't like to work at less than 2M with the Philips TV & Panasonic player combination
The G1080 will allow you to work with longer cable lengths & still maintain the utmost quality & this is what i needed. No idea what the same length of cable would be like compared to the G720, logic tells me it'd be better, but whether this would result in an improved picture at the end of the day i honestly don't know
