hey guys

As I think we all knew - CRT monitors and TV's where always marketed with the width of the bezel included in screen size, ie a 17" tv / monitor actually only had a 16.5" viewable screen ( at best) and I seem to remember the bigger the screen the more scren size disappeared behind the bezel.

However when TFT monitors came out - and the initial load of LCD tv's - they had a viewable screen size and marketable size being exactly the same - ie bezel was NOT included

Now have any of you noticed, certainly during Xmas sales etc in all the papers the LCD tv's have stated "shrinking" to how CRT's were marketed? Numerous ads have in small print the vewable size being smaller on LCD's than what they say in big type and on model number
 
I always thought it was because a 15" LCD was 15" diagonally... because it's flat, that's all you can measure... there's a definite "edge" and there's no ambiguity?
 
No the reason CRTs had a bigger diagonal is as FrankJH says, the actual screen continues in behind the bezel so they include this even though it isn't viewable to the user.

On a LCD screen the screen ends at the bezel, there's no viewable area in behind (or there shouldn't be).

That was my point (:o)- the screen size of the LCD is not ambiguous, and as such you can only make one measurment as there isn't going to be any of the screen area obstructed by the bezel on an LCD.

So I don't get why there would be two measurements for LCD screens...

Well, technically on CRTs there's no ambiguity either, visible diagonal is still measurable, but manufacturers always went by the tube size. It's similar to HD manufacturers using 1000bytes in a kilobyte just to make the disk look bigger.

Of course it's still measureable, it's just when describing the screen size of a CRT some manufacturers used to omit whether it was visible screen size or tube size.
 
Exactly what I was saying - there shouldnt be ambiguity in lcd sizes however if you look at big adverts in daily papers for highstreet stores, most are now saying a smaller viewable screen size ( I havent noticed if one manufacturer is worse, but it seems to be most of them)

I certainly saw several 32" lcd's being stated as only having 31.5" viewable screen. I had hoped that the manufacturers had got out of this habit, but now they are popular think the glass makers are taking the p*ss

It may only be 0.5", but it shouldnt be excusable in my opinion - at least with CRT's they had a sort of reasonable excuse, with lcd's they dont
 
On my LCD TV the screen has a very small black border around the edge which it can't display on, I assumed this was why my 26" screen had a viewable size of 25.xx" or something like that :confused:

Edit: Just remembered its 25.6" viewable which means approx 0.2" border which is about 5mm ish which sounds right.

Exactly my point - you lost just under 1/2" ( about the same as you would have lost on same sized crt) when this is technically unnecessary.

Anyway, the main point i was making is I wonder if they have started doing this with TF monitors as well, without being so obvious about it
