deffinitely get a HD tv and then a blue ray player aswell.
I've got a Sony 40v4000 and a Sony BDPS-550 Blue Ray player and the image is just amazing compared to my old Denon DVD Player.
it's a great investment

But make sure you connect with a HDMI cable NOT component.
Alot of Blu Ray players don't come with a HDMI cable in the box.

And don't get caught by the salesman's bullshit about how "buying a better - more expensive - quality HDMI cable will give you a better picture" - it's complete bollocks...
Buy the cheapest one you can possiby find - makes no difference at all...
It's a digital signal - therefore either works or doesn't - it's not like an analogue cable which does make a difference.....

when i got my blue-ray i checked it out first in the Sony Centre. they wanted £330 for it but a google search pulled up a price comparison site and i bagged it for £220 delivered  |

Can anyone verify this? I'm in the process of self-installing a multi-room AV system that feeds to all rooms from a central location... I've held off buying the expensive HDMI cable as it will set me back the best part of 3 grand will the cheaper stuff really do the same job without flickering? I'm going to be sending 1080P signal over this |

what length do you need for the HDMI cable? £3k is definitely too much

Triseros - think of the signal that is going down the cable....
It is 0's and 1's - binary code (digital)
It either travels down the cable or it doesn't - there is none of this "some get there and some dont" business - it either works and sends the signal in it's entirity - or it doesn't.
Analogue cable is completely different - this will offer better signals if the quality is better etc....
Digital HDMI cable makes bugger all difference - either works or doesn't....

5 x 10 metres 3 x 5 metres I was 'advised' that I would need boosters and all sorts of shit... |

Cable length
The HDMI specification does not define a maximum cable length, but because of signal attenuation there is an upper limit to how long HDMI cables can be made.[56] The length of an HDMI cable depends on the construction quality and the materials used in the cable.[56] Adaptive equalization can be used to compensate for the signal attenuation and intersymbol interference caused by long cables.
To reduce the confusion about which cables support which video formats, HDMI 1.3 defines two categories of cables: Category 1 certified cables, which have been tested at 74.5 MHz (1080i/720p), and Category 2 certified cables, which have been tested at 340 MHz (1600p).[57] Category 1 HDMI cables are to be marketed as "Standard" HDMI cables, and Category 2 HDMI cables are to be marketed as "High-Speed" HDMI cables.[1] This labeling guideline for HDMI cables went into effect on October 17, 2008.[58][59] Category 1 and 2 cables can either meet the required parameter specifications for inter-pair skew, far-end crosstalk, attenuation, and differential impedance or they can meet the required non-equalized/equalized eye diagram requirements.[57] A cable of about 5 meters (16 ft) can be manufactured to Category 1 specifications easily and inexpensively by using 28 AWG (0.081 mm²) conductors.[56] With better quality construction and materials, including 24 AWG (0.205 mm²) conductors, an HDMI cable can reach lengths of up to 15 meters (49 ft).[56] The HDMI website has stated that many HDMI cables under 5 meters of length that were made before the HDMI 1.3 specification can work as a Category 2 cable but cautions that only Category 2 tested cables are guaranteed to work.[60] Long cable lengths can cause instability of HDCP and blinking on the screen due to the weakened DDC signal which HDCP requires. HDCP DDC signals must be multiplexed with TMDS video signals to be compliant with HDCP requirements for HDMI extenders based on a single Category 5/Category 6 cable.[61][62] Several companies offer amplifiers, equalizers, and repeaters that can string several standard HDMI cables together. Active HDMI cables use electronics within the cable to boost the signal and allow for HDMI cables of up to 30 meters (98 ft).[63] HDMI extenders that are based on dual Category 5/Category 6 cable can extend HDMI to 50 meters (164 ft) while HDMI extenders based on optical fiber can extend HDMI to 100+ meters (328 ft).[56][63] http://en.wikipedia.org/wiki/Hdmi |

It's Friday Morning and I was watching all 4 episodes of The Wire until 2 this morning and I'm having a JFW moment |

Erm, that's not true SS. It doesn't matter what format the signal is (analogue or digital), all copper cables have physical resistance and will attenuate a signal over a length of cable. At some point on a long cable the digital square waves will be reduced in amplitude to a level that won't drive the receiving end. That depends upon a lot of factors such as wire thickness, shielding etc. Fizzics, innit? |
