Hello fellow CAG members.

I finally decided to buy a LCD TV this weekend and i need help choosing the right one as i am no expert on this TV.

Anyways.. ill be using this TV mostly as a computer monitor, play games or watch dvds. Probably use with PS3 later this year..

I see there are many specs such as 1000:1 Ratio or # of HDMI outputs..
Im not sure what those mean..

Any help appreciated..

Right now, i am looking at 32" Viewsonic at newegg. Price is decent and good reviews..

Should i look into Sony or Samsung?
Any other specific specs i should be concerned?

Thanks!

[quote name='Number83']I have a Sharp Aquos 32' LCD TV...Anyone know why it emits a constant humming sound?!? I have ruled out interference, as it has been all over the house. I have a call into sharp and they are sending someone out to replace the power supply. I was wonderng if anyone else had this issue.

I also have a Panasonic 32' LCD, and I notice that the blacks are extremly black when playing my 360, especially Perfect Dark Zero. Can anyone suggest sharpness/contrast/color settings that would be optimal?

Thanks![/QUOTE]

For the Sharp, it could be "dirty power". It's bascially interference and small surges in your power. It can best be described as what you see when you run a microwave and vacuum and get lines through the tv picture. It also causes speaker noise.

To fix something like that, you can get a Monster Power surge protector that will "clean" your power. They can go for anywhere from $89 and up depending on what you are hooking into it and the amount and type of interference it can clean up.

It could be the tv obviously too, so let Sharp check it out for you.
 
[quote name='greendj27']Samsungs are actually some of the best LCDS on the market for the money and usaually will give you a similar or better picture than a lot of the Sony's for a lower price. That 26" Sony Bravia XBR has something like a 1200:1 contrast ratio while the 2651 Samsung is like 3000:1 for a similar price.

Understand that most panels can't break 1500:1 native contrast, most CR numbers like 2000:1, 3000:1, 4000:1 in an LCD are acheived through trickery, not native contrast ratio of the panel itself.

ImageAI or other such names are often used to pull those numbers, and they are almost always inflated....LCD Flatpanels usually do backlight modulation to get higher CR's in dark scenes, but it isn't always accurate.

Of course Contrast Ratio and overall Black Level are two different animals...LCD's usually dont do very well in overall black level, but they do ok now with CR if you buy one made with a quality LCD panel like the Samsungs, the Sharps/HP's, or the Sonys.

That said, LCDS in general are usually not that great for gaming on because of poorer refresh rates. They are improving, but still have a ways to go.

True, but you can see ghosting or trailing in almost any technology besides DLP...Plasmas, CRT's, and LCD's all do it to one degree or another.

Thanks for the quick response. The crazy thing is, that the humming isn't coming from the speakers, but more like the screen (is that even possible?)...which is why I don't think it's the Power Supply. But Sharp Customer Service is pretty decent so far, so hopefully they're right.

Thanks Again!:D
 
Its the backlighting.

Same problem plagued other brands of flatpanels.

Do you have the ability on your set to adjust the backlighting directly? If so, try turning it up or down to see if the humming goes away.

Basically, you're hearing the same Hum you get from a flourescent bulb if its dimmed or faulty.

I do have the ability to change the Backlight (1-14) but that did not work. That is exactly what it sounds like!

Thanks!
