TV Screen Size

[Guest]

Archived from groups: alt.tv.tech.hdtv (More info?)

I wish to by a 16x9 TV. My concern is that different size screens sometimes
cut off the top and bottom, or the sides of the pictures even when in the
correct mode, in other words not TRUE 16x9. Because of this, what diagonal
screen size should I go for and also avoid. i.e.. it seems that 44"
widescreen TV's cut off the top and bottom of picture

They only CUT off the screen if there in the wrong mode. I think
you're misinterpreting what you're seeing.
All TV's will display the whole picture that is being broadcast. At
least in the US.

I'd guess that this 'edge cutoff' problem is related to

CRT (cathode ray tube) displays.....

It could be caused by Zoom, stretch, overscan, or

bad adjustment.... Bad adjustment covers overscan too.

I'm guessing the better CRT sets have less frequent cutoff

adjustment problems... They are more stable...

=======================================
Cropping top and bottom has NOTHING to do with the size of the 16:9 screen.
It has to do with what mode you use for viewing.

Your correct, this seems only to happen to CRT. That's one thing I never
considered, thanks. Looks like im going down the LCD route.

It happens even in the correct mode.

Actually almost no TVs display the whole picture being broadcast. Sometimes
as much as 15%-20% of the edges are lost to overscan.

I think you are seeing the difference in overscan from set to set. There is
nothing about a particular size of screen that would cause this, and there
might be some variation even amoung sets of the same model. Test patterns
such as Avia or Video Essentials, can show how much overscan there is. A
technician can adust this.

Actually LCD sets will have overscan also. There is some variation of
picture size from channel to channel which needs to be covered up. A CRT
set with a weak high voltage power supply will let the picture expand during
bright scenes.
Sometimes you can see a little jump in the picture if there is a sudden
change of brightness. LCDs wouldn't do that, of course. Good CRT sets can
be adjusted down to 3-5% overscan, but few come from the factory that way.

I definitely have the TV in the right mode. I'm aware of wide, smart, 4:3
and so on. E.G., on some TV's displayed in shops, one will have half the
screen logo showing and the TV next to it shows it all. Both are in the
correct wide mode.

You can use the TV Apsect Ratio comparison to compare picture area
between 16x9 and 4:3 sets.
