Not all TV support HD res. up to 1080 for all connections?

ahuang · Sep 19, 2007 3:16 pm

I read in an US Magazine (Home Theater Jan 2007) that:
"Component, HDMI & DVI connections all can support HD resolutions up to 1080p, but it's up to your TV’s manufacturer to decide which resolutions to support through each connection. For bandwidth and copy-protection reasons, many choose not to accept 1080p via component video; some don’t even accept it through HDMI."

Is this true? So this means that even if a TV claims to support 1080p, we still have to check through the user manual to work out which connection supports and which one doesn't!! That's a lot of unnecessary work!

I am sure Matt and or Rod will get on to this pretty quick also.....
But as I understand things, any viewing equipment eg, Plasma, LCD, TV or Projector all can say they support 1080P but are not necessarily going to give you a true image of 1080P.
A high definition Digital settop box (1080P) will still run through any TV including ones that say it supports 1080P even if it is 720P maximum viewing.
That doesn't mean you are getting a true High Definition Digital 1080P viewing.
Sorry if a little confusing..... Cut a long story short.. almost all television are 1080P supportable as you can watch it but the clarity of true 1080P is not available untill the rest of the compnents are compatible not just supportive...

Allan, your info is completely accurate.

Arkraider, a couple of clarifications:

1. Hi-Def set-top-boxes output up to 1080i (nothing is broadcast 1080P - that's the domain of Blu-Ray/HD DVD and PS3/XBox360 consoles).

2. Most TVs these days can receive and display up to a 1080i picture, especially Plasmas and LCDs. They do this simply by down-scaling it to whatever it's native resolution is. 1080P, however, is another step up again (as indicated above), and can only be displayed by newer devices that specify they can. If it's a true 1080P (1920 x 1080) display then it obviously doesn't need to down-scale a 1080i (or 1080P for that matter!) picture at all.

Hey Rodda, I see that True HD plasma's/LCD are becomming more and more available on the market.

Is there a next generation technolgy after True HD?
I have been waiting for True HD to become more available, and hence cheaper, just wondered what the next big thing/technology will be in displays?

Hi mate.

There's nothing above True HD 1080P (1920 x 1080 progressive) on the horizon (yet). Blu-Ray and HD DVD haven't really started taking off yet, and that needs to be cemented before consumers start looking beyond it. Remeber that it's not just the increase in picture resolution on offer by these new formats, but also the improved sound formats as well (Dolby Digital Plus and DTS Master Audio). I reckon that should sustain the audio/videophiles for a while...

The more manufacturers come out with 1080P devices, the more they will all compete for their market share, so that will drive the prices down to a degree. Just how much, we'll all just have to wait and see.

If you go back and watch a VHS version of one of your favourite films, that you now have a good version of on DVD (some early transfers were a bit **), it will clearly demonstrate what an improvement the newer technology delivered. Maybe in a couple of years we will be able to say the very same thing about Blu-Ray/HD DVD vs plain old Lo-Fi DVD

.

One big draw back, one that I'm not looking forward to in particular, is the notion of replacing my 550+ DVD collection with the Blu-Ray/HD DVD versions...

Thanks for that reply Rodda.

I have been holding off buying dipslay panel, waiting for true HD to become more avaliable. (not in any hurry).

Maybe after Christmas sounds like a good time to buy.

One problem with all these HT, Computer high tech stuffs is, once You paid $x on the latest greatest product, 2 weeks later either the prices dropped again or another new model with better feature comes out with the same price....

always the way isn't it.

This is why "most" people never upgrade!!

Always waiting for the best/newest/most feature packed model to come out...

No matter when you buy there will always be something better come out. Look at cars, houses, mobile phones.

Anything with technology in it will be outdated and nowadays reasonably quickly. Always buy the best you can afford and don't worry about what "Mr Jones" has.

I remember paying $5000 for a standard def LG plasma (a bargain at the time) that 4 years later is worth maybe a couple of hundred dollars if I am lucky.

Don't even get me started on things like my first 40 megabyte Hard drive for my computer that I paid $600 for and my first AT computer that was nearly $3000.

Take the leap ... or in the words of a great American Company:
