Geeze Willobandb...I just spent thirty minutes lurking on the A/V forum. Some guy posted..."CRTs aren't capable of displaying the 1440 lines for a 720P* source..." What??? I lost count of the number of posts where people don't know the difference between vertical and horizontal resolution. Thanks for the link but I'm afraid there's a lot of mis-information being dispensed on that site.
*720P has is made up of 720 horizontal scan lines (vertical resolution), not 1440. Assuming the pixels are symmetrical (round or square), a 16X9 display would yield horizontal resolution of 1280 lines.
It's no coincidence that 720X1280 is the native resolution of most HD plasma's, DLPs and LCDs. Now if we only knew what the real resolution is with 7" CRTs... or should I ask, can a 7" CRT display a 4 mil. (.004") spot???
