HD TV advice ( beginner)
I particularly liked the marketing term, Lifetime guarantee.

TV's in the shops now have either LCD screens or Plasma (for larger sizes over 40), but there is a new type just coming out - LED. LED models on display seemed to me to have exceptionally clear picture. They are very slim at just over an inch, and use around 40% less electricity. Less than what? Not less than a CRT I'll wager. How does their power consumption compare with a CRT? As there are no full HD cathode ray tube model TV's on the market (AFAIK) is that a realistic comparison? I thought idea with product promotion is to come up with significant sounding but meaningless statistics such as: 40% less. - Less than something that is 40% more of course ;-) Roger R |

Is not the efficiency only that the light output is variable in areas on led
backlights to mask the grey black problems of lcds? I had a chat with someone the other day who did not like the new led backlit screens as although the dynamics of black/white seemed better, detail in black areas was sometimes missing as well. Of course this could have been content or set up related, but as I can no longer see these things myself, its interesting to hear peoples take on these things. I was imagining a situation where a tennis ball went dim when it was surrounded by a dark background in my mind!

My 14" CRT consumes more electricity than my 15" LCD, and you seem to be saying that LED backlit LCDs are more efficient again than my relatively ancient lamp backlit model! ====================================== Please always reply to news group as the email address in this post's header does not exist.

My 46" LED/LCD TV consumes about 70W when displaying typical pictures, about 45W with no input signal, and 3W in standby. How does that compare? But what are we going to compare this with? Compare it with the power consumption figures of other TV sets with different display systems. Then we will know the actual quantitative truth of the matter, not just the folklore and the advertising hype.

Of course this could have been content or set up related, but as I can no longer see these things myself, its interesting to hear peoples take on these things. Digital bit-rate reduction reduces or removes detail where it is thought not to matter, and this often shows as a reduction in detail in dark picture areas. Maybe the dynamics of LED displays make dark detail more visible, so it becomes more apparent when there isn't any? As well as the digital processing performed by the broadcasters, modern TV displays include a lot of "enhancement" features, most of which are switched on by default, but do not always improve the picture. To compare like with like, we should make sure two displays we are comparing are set up in the same way, preferably with the gimmicks all switched off. It probably isn't very meaningful to compare displays in a shop. Rod. -- Virtual Access V6.3 free usenet/email software from http://sourceforge.net/projects/virtual-access/ |

Most the HD displays at trade shows in the 1980s used CRTs, some of them about 40" as I recall. That seemed to me then, and still does, to be about the smallest screen size where the extra detail would be worth the bother. The boxes containing these CRTs were understandably huge, even the back-projected ones, which probably explains why no serious attempt was made to flog the system to the public until the availability of flat screens.

My *TV has broken and I want to get a new one. *I have decided to move my old 26" TV into the bedroom and get a new main TV for the sitting room. I have seen two TV's which *I am keen on *( Panasonic 37" screen) *, The only difference between them other than price is the HD. One is HD ready, the other HD fully ready. Can someone please explain this in very simple terms *( for a girl) *so that I know which I should get . *What is HD and do I need a set for this and why anyway? Are they going to change digital the HD or something? "HD Ready" is a Logo, it just looks like English - i isnt. Take a look at this page: http://www.eicta.org/index.php?id=731 You will have to match the TV set with the kind of TV signal you are receiving. With digital - unlike analogue - the signals received from an aerial, a cable or from a satellite are all very different. If you are using an aerial you should know that the UK will broadcast HD starting this December*, but you MUST have a new dvb-T2 receiver. This DVB-T2 receiver will arrive in volume within the next 3-6 months. You should also know that the full 1080p50 HD signal is unlikely to be broadcast from any source. Even BlueRay disk does not deliver the full framerate - AFAIK. Lars :) * In all areas post-DSO + London and 4 other large pre-DSO transmitters. |
