Default 32" Vizio LCD, 16:9 video not in full screen

Hi people


I bought a VIzio VW32L TV and am having issues with it's screen coverage.

When I watch normal TV over the antenna everything is fine:
4:3 programs take up the entire height of the screen and there are the expected black bands on both sides
16:9 HDTV programs cover the entire screen!


However, when watching a DVD the picture only covers about 2/3 of the screen (both horizontally and vertically).
The DVD is wide screen format and is displayed in the correct wide screen ratio, but only on 2/3 of the screen (effective about 24").
There are black bands both on the sides and top and bottom!
During the DVD menu when the picture is still at 4:3 the menu does cover the screen properly (full vertical coverage and black bands on the side), but as soon as the movie starts the problem is there.


This happens both with a bran new Phillips DVD player and a PlayStation2 used as a DVD player, on both composite and component inputs and with multiple discs.



This doesn't seem normal, should I return the TV?



Thanks for any ideas

Post They call this matchbox, when all sides have black borders.

My thoughts are that you have the DVD player set for 4:3 aspect, so when you have a widescreen DVD playing.. it shows it within the 4:3 aspect. Check your DVD prefs for this (try not using the 'progressive' feature, to see if that makes a diff). If you use the Zoom and it stretches to only 4:3 aspect but get rid of the top bars... this is a sure sign of 4:3 aspect.

Keep in mind that some videos (usually non commercial, internet downloads are famous for this) are encoded in 4:3 aspect as WS and nothing will get rid of those bars on some DVD players.

I doubt the Panel is defective... but you can see that aspect flexibility is a very important issue. So..

recap: DVD player has aspect controls, Display has aspect controls, DVD media has aspect encoding.

Yeah, sounds like the settings are screwie somewhere. When connecting the DVD player with component, if set to progressive scan, and 16:9 or widescreen, there should be no bars on the side. At least I don't. I know with the PS2 when connecting it with the PS2 component cable, you need to set it to progressive scan and then widescreen in the dvd menu. But it's been a while.

Whith my DVD players, it is all automatic. Even if I put an old 4:3 DVD in, it will fill the entire screen. No bars at all.... I also doubt it is a defective TV, but anything is possible.. Make sure to read both manuals again. But you probably did that 10 times already...

Thanks

The DVD is actually set to 16:9 and progressive scan.
When I zoom it stays at 16:9 and the same coverage area, but I see a smaller portion of the scene (which is what would be expected).

I don't actually think the TV is defective since I can get full coverage from the antenna or by stretching 4:3 content so all the pixels are working, this just seems to be poor implementation in the TV's firmware.
Vizio have not responded to me yet and I can't find a firmware upgrade so I was just thinking of maybe returning it and getting a different model/brand.

I ended up just returning it since I got no response from Vizio's tech support.
The new one works great (it's a 37" Insignia - best buy brand).

Well, it was behaving as if the DVD player were set for a 4:3 display and not a 16:9 display (it will format widescreen movies into a letterboxed 4:3 window in that mode). Also, widescreen movies that are actually letterboxed (not anamorphic, or "enhanced for widescreen TV's") will display that way.

But since you changed to another display and it works fine without changing anything else, that's really confusing. Are you sure your new TV isn't just displaying a letterboxed image that has been zoomed to fit?

Zooming is a bad thing, as it has much worse resolution than a true anamorphic (squeezed) widescreen image on a widescreen display.

The old TV only had 3 modes: normal, wide, panoramic

In normal mode the playback was on 2/3 of the screen as demonstrated, in wide it was stretched horizontally but not vertically making everything distorted.
The panoramic mode is some sort of sick joke, it keeps the center in it's correct ratio but stretches the far edges to fit the screen making it extremely distorted.

It didn't have a zoom feature (the remote has the button but the feature doesn't exist, like PIP).

The Panoramic mode is actually useful for watching SD (4:3) programs if you don't like side pillars (and want to avoid uneven phosphor aging on Plasma and CRT displays).

If you were watching a movie in the display mode meant for anamorphic Widescreen DVD's (I'm assuming Wide mode, but not sure) and it looked stretched, that means it wasn't an anamorphic widescreen DVD (which will look squeezed--everything tall and thin--when viewed in normal mode).

Check your DVD's, if the box says "Full-Screen", "Letterbox Widescreen" or doesn't say "Enhanced for Widescreen TV's", then it is not meant to be stretched and the only way it will display properly on a Widescreen display is by zooming it. If this is the case, it's best to replace those DVD's with anamorphic Widescreen DVD's--they will look much sharper.

I don't know if anybody is making Letterbox Widescreen DVD's these days--they were strictly meant for displaying Widescreen movies on non-Widescreen displays. Current DVD players are designed to automatically format anamorphic Widescreen DVD's for the selected display type--they will transmit a full-height squeezed image to a 16:9 display (which will stretch it to the proper aspect ratio) or transmit a Letterbox Widescreen image to 4:3 display. Some will let you Pan&Scan, which will show only the center portion of the film normally and allow you to scroll left or right to see the rest of the Widescreen image.
