Yes, the screen size is normally given as the diagonal since that gives the largest number for advertising purposes.is the size of a TV not given as the diagonal of the screen?
Then the PPI will be diffrent as the side is smaller as the diagonal.
A 75" diagonal TV has a screen width of about 65.4".Well I have the TCL 75R635 TV and it is 4. K and 75 Inches.
What is my PPI?
Did you not read my post #8?Well my LCD TV is 75 Inches.
Just to but in, the diagonal measurement is historical, the original cathode ray tubes were circular and the the dimension given was the outer diameter of the glass tube. The maximum picture size was limited by the diagonal, which would be much smaller.Yes, the screen size is normally given as the diagonal since that gives the largest number for advertising purposes.
But if you notice, I used the width of the screen and the number of horizontal pixels, not the diagonal in my calculations.
For a 50" width, the diagonal would be about 57.4"
It seem that some set makers use a stretchy tape when measuring that diagonal, and they round up to the next whole inch. And sometimes they will add the qualifier word "class" so that a 49.4 inch screen is a "50 inch clas" sized screen.Just to but in, the diagonal measurement is historical, the original cathode ray tubes were circular and the the dimension given was the outer diameter of the glass tube.

I suspect that screen manufacturers probably work with metric dimensions anyway.It seem that some set makers use a stretchy tape when measuring that diagonal, and they round up to the next whole inch.

Crutschow does have it correct, though. The pixel pitch i based on the width, not on the diagonal.
Just think about the confusion if they start claiming diagonal sizes in millimeters!! Really impressive big numbers.I suspect that screen manufacturers probably work with metric dimensions anyway.
An easy way to increase the size of the picture, at no extra cost, is to move your chair closer.Just think about the confusion if they start claiming diagonal sizes in millimeters!! Really impressive big numbers.
They masked the top and bottom of the round screen but left the sides curved to give a somewhat rectangular picture (below), so the diagonal was the same as the width.Just to but in, the diagonal measurement is historical, the original cathode ray tubes were circular and the the dimension given was the outer diameter of the glass tube.

Here are the specs on your TV..59ppiWell my LCD TV is 75 Inches.
So if I do 3840 Divided by 75 will this give me my Pixel Pitch?
