Do all LCD TVs have a slow refresh rate...

dwell

pics?
I am finally considering the HD plunge and have been looking at sets the last few days. I heard good things about the Sharp AQUOS so I checked out the LC-42D62U at Best Buy yesterday. I have not had any exposure to LCDs other than computer monitors, bu it seemed to me that all the display units (not just the Sharp) displayed artifacts when there was a lot of movement onscreen.

Are all LCDs like that, or was it their set up? The AQUOS has a 6ms refresh rate which is supposedly fast, but if I had to look that artifacts like that all the time I might as well save $2k and stick with my Wega CRT.
 
Did you check to see if any of the other types of displays in the store had the same artifacting? Could just be a really crappy in-store video feed.

Fixed your post 😛

If they are using a satellite feed, that pixelization is due to high compression of the feed. DirecTV is awful for this and all high action scenes (fire is the worst) breaks up into pixels.

HDTV is no longer HD.

It looked like every display in sight had artifacts. It looked sort of like little squares all over the screen that lagged behind the movement. I am sure their set up was horrible, but man, that's no way to sell sets!
 
has anybody ever tried to ask them to play a DVD of your choice or get the remote and adjust the contrast... I have heard that you can do that but never actually spoke with anyone doing that. Do you allow that?

That's the compression Amused was talking about. You see it a lot on HDTV feeds these days 🙁

looking at that model as well. it's the video feed that creates the artifacts, not the TV itself.

Yep. Went to BB one time to check out a HDTV and they didn't even have a HD feed going to it. Had to point it out to the BB rep and we ended up changing the channels on a few HDTVs so that they were receiving the HD feed.
 
I own that TV so if you have any questions about it, feel free to ask. My personal experience is that the TV has no problems with displaying fast motion video. I will occasionally get artifacts when there is fast motion from my DVR but I've never had an issue from HD-DVD or fast motion without the DVR. I hope that helps.

TimeWarner isn't a whole lot better - check the lighting duringa rock show on INHD. It's always super pixelated.

Wish there was an uncompressed source w/ decent content.

Sad, isn't it?

I remember when I first got an HDTV and DirecTV. There was no noticable compression and the picture was simply stunning. You could see a fire, or a breaking wave and it looked like it was going to leap out of the TV and get you.

The "over" series HDnet used to air was stunning, making you feel like you were going to fall right out of the plane as they flew over some of the most stunning scenery in the world.

The picture was so clear, it looked 3D.

Now it looks like crap. 🙁

I'd blame BB's video distribution. I have the entire D62U series on display in my store and they look great. Some of the best LCD I've ever seen with color and black levels approaching some of the best Plasma on the market.

BB employees are NOT experts in the field of home theater. Look at their TV displays. Every time I go to a BB the pictures are all different aspect ratios and the clerks have no idea how to set them right. It blows my mind that anyone would look to a box store (BB, CC, Sears) and expect them to be an expert in the field. You don't go to Wal-Mart thinking they are an expert at anything. You don't go to Home Depot thinking the people there can tell you how to build a house. Why would you look at BB as being any different than any other box store out there? They aren't. They're just another crappy box store staffed by box store employees.
 
..my 40" sony bravia was the best looking of the bunch that costco have on display including the aquos. the worst looking was the vizio. I chose the bravia because it has the best chroma accuracy and best contrast.

The worst example I can think of it when a bunch of shiny confetti is falling. For example, after this past weekend's NFC/AFC championships games. Any place there was a bunch of confetti on the screen the image was horribly blocky.

So do you think this is permanent or will get better as they bring more bandwidth up? I can tell you that when I was watching football on NBC in HD on DTV it really looked like crap but it looked like the same crap when I checked on Comcast so I suspect that the problem is either NBC or my local affiliate. I'm too far out to get OTA without an outside antenna so I am pretty much stuck with DTV or cable.

I love it except for one small problem. When the backlight is on any setting other than the highest the TV emits a high pitch squeal. It's something that I've been meaning to talk to Sharp about but I haven't gotten around to it yet. The TV will also adjust the backlight if the information it's displaying is mostly black so it'll get better black levels but unfortunately, that makes the TV squeal too.

You'll read about banding problems that people have experienced with the 46" and the 52" but the 42" doesn't seem to exhibit those problems (mine in particular). The 42" is manufactured in a different facility than the other two which could explain why it doesn't have that problem.

If I were to go back to when I was making the decision on which TV to buy, I would still buy this one. I should mention though, I've not once used the speakers built in to the TV so I cannot comment on their quality.

I don't think it will get better. Now that they realize they can get away with this much loss of quality, they will continue to do it to fit more channels. The average joe wont notice the lame quality and only cares about channel counts.

This exact same thing happened with their SD channels the first few years DirecTV was out.
