Question Can component cables carry 1080p??

Sorry if this was already asked before in the past but I need to confirmed this..

Can component cables carry 1080p signals.. or is it only up to 720p/1080i???? can anyone confirm this for me please??? thank you

Default Component and 1080p

Most of the component cables can carry 1080p pictures. If you can upgrade to a digital cable, I would.

I don't know of any monitors/HDTV's whose Component inputs accept 1080p... that's a different question though, I suppose.

ok thanks, all i need to know was that, see i was aware of for some time now that component cables could only carry HD up to 1080i(including 720p of course) but i wasnt aware it could carry 1080p, i thought only DVI/HDMI could carry up to 1080p. thanks

Good question.

The next generation of HDTV's will have 1080p resolution, nearly twice what we have today...and todays component video cables will not be able to transfer the 148.5 MHz signal needed to accomodate this demanding resolution

Maybe they are pushing their cables? Maybe it has some fact?

Your common old everyday RG6 will carry 2-3 GHZ - 10-20x that .1845 GHz
possibly?? needed for the Green component Video connection - no exotic cable needed - besides - the Blue and Red only need half that maximum bandwidth -about what a Green cable requires for 1080i presently and within the tolerances that any well designed cable - would already possess just to be on the safe side(100% overspec)
I love it when those math challenged writers [HDTV Supply] use 4 decimal precision for halfbaked ballpark numbers - 184.5 MHz
the actual highest video frequency for the 1080p intensity signal (green plug) is (1920)/2 x 1080 x 60 or about 60Mhz - since it only takes 1 analog cycle (up and down) to produce 2 pixels - one dark and one light pixel next to each other - the highest possible required frequency -the color signals are combined on the other (red&blue) component video cables at half or less the required intensity bandwidth

Damn! Those cables are SO good, it's amazing they could drop the price from $99 to $39...

They should get out of this 'we test everything' crap, much of their basis is full of holes. Maybe they think it will impress the less informed.
If the cables are well made there is no need to test every one.

Last time I saw cables with VALID test data were matched UHF cables used in a military communication test set. The data cost as much as the cables. Not cheap as you would imagine..

1920x1080 at 60fsp is about 124MHz. It is not the cable itself, but the RCA connectors. RCA connectors were designed for baseband video (~10MHz). HD component video is still in their realm, but 1080p is outside what the connectors are able to do. If you use BNC connectors then no problem. I dont know of any component video devices that use BNC, maybe the professional stuff. That is another thing Monster Cable does not tell you. You can shield that RG6 and sweep test it to 3GHz all you want. When you mate it to crappy RCA connectors then that is your weak link. I wish the video industry would have gone to BNC back a long time ago.

Where do you get the 1920/2?? I believe you are getting 1080i mixed up with 1080p. In 1080i you get 1920x540 for the first set of lines then another 1920x540 for the second set of lines. Those two fields are drawn on the screen in alternating fashion to make one frame. 1080i is 30fps video. 1080p is 60fps. 1080p requires double the bandwidth of 1080i. Remember, the cable is not the limiting factor, the RCA connector is.

Refer to the calculations below:

SD - 640x525x30 = 10.1MHz (only 480 are viewable)
ED - 640x480x60 = 18.4Mhz
HD 720p - 1280x720x60 = 55.3MHz
HD 1080i - 1920x1080x30 = 62.2MHz
HD 1080p - 1920x1080x60 = 124.4Mhz

Simple calculations.

very usefull..thanks, i never knew any of that stuff.. so in other words component cables can indeed carry 1080p, but its the connectors themself that cannot transfer the 1080p from the cable to the TV??? am i getting this correct????... so are there any known component cables that are fully capable of not only carrying 1080p but transfering it to the TV???.. it still makes me think how the hell does sony expect their "basic PS3 model"(20GB, no HDMI) to output 1080p, they are swearing their life on it.

I donít understand your calculations because in the first one you include vertical blanking but you donít include all off the active pixels or the horizontal blanking (the total would be 858x525x29.97). In SD the total active pixels are 720 but I think only 704 are broadcast not 640 and there are 485 active lines not 480 except in MPEG then itís 480. Also all of your totals are in composite video because SD component video is 270MHz (858x525x29.97x2x10=269,999,730) and HD is 1.485GHz.

Exactly, RCA connectors suck. They have bad frequency roll off up past 100MHz. RG6 is good to about 3GHz.

so your telling me i would have to find component cables that have RG6 connectors??!?!?, and what do you mean by "RCA connectors", are you refering to just normal connectors that you see on every cable(composite, component, audioL/R cables etc..)... would that include the "gold plated" connectors.. i heard the gold plated connectors are better because they provided better contact.. and i thought RG6 was a Coaxial Cable, are you saying that i would have to find component cables that have the RG6 type of connector!!!??? .. i dont think that even exist or does it?
