How do you measure LCD screen?

Answer 1

Screen size is measured in inches diagonally from corner to corner ---- Measure from the bottom left corner to the top right, this will give you the correct measurements, however if you have a standard LCD screen, and compare it to a wide screen version, you may get the same measurements as each other, however due to regular programing, you will notice that the right and left hand sides are blacked out because of the conventional non hd-tv formats, so the best way to avoid this issue is to measure your old conventional tv set's height and compare it to the new lcd you wish to purchase, make sure the height it the same, this way when watching standard programing you still get the same viewable screen space as you had with the old tv.
