I have a question for you...
why have you payed a 45" LCD when some plasma TV are cheaper?
what are the criteria behind your choice?

I have tested the Aquaos 30", but I have returned the product. Maybe the
contrast ratio of 500:1 (instead-of 800:1 on new model) is the cause of my
complain:
I have a lot of problems to setup correctly the colors.

Is it a great difference between 500:1 and 800:1?

Also, viewing standard TV without digital decoder does not provides a good
quality.
Have you tested this?

Samsung start the production of new LCD screens for computers with a better
response time (8ms instead-of 16ms for actual models). Does this type of
technology is also used today in LCD TV?
And does it better to wait a little to see these new technologies?

thanks for your answers and knowledge sharing :-)

Hi Robbie,

Like you I bought the Sharp 45" LCD. And, using just Powerstrip was
able to get it to 1920 x 1200, and although it was a bit underscanned
horizontally (there was a black border on both sides), and a bit
overscanned vertically (I couldn't see the task bar) - things looked
great. I did this by playing around with the clock frequency under the
"Fine Sync." option in "Setup" in the Aquos menu.

However, I had to reformat my computer, and lost the Powerstrip
settings for this. I realize my set up is a bit different: I was
simply using a 9200 ati mobility (in an HP zt3000 laptop), and I used a
VGA to DVI converter - not HDMI. Do you mind posting the Powerstrip
settings you are using?

You mentioned you were using a Crucial x800 video card - what timings
are you using to get to 1920 x 1080p?
Any help would be appreciated. Thanks.
