Notes On Columns:
  • Horiz & Vert To test if screen looks fuzzy, excellent was a Discovery Channel documentary of a USA aircraft carrier: Much small detail, including shallow drooping cable runs in corridors, which really tests the pixels. A Panasonic Plasma TH-42PV60H (106cm) @ 1700 EUro in Conrad.De) was much less grainy than a Philips 42PF7320/1D that cost 100 or 200 Euro more I recall.
  • Acronyms All wide screen formats with vertical 768 - 1023 shown as WXGA.
  • Aspect Ration Approximate collequial approximate integers.
  • Aspect Decimal Exact Decimal from Horiz / Vert .
  • CommentExact: 2.54cm = 1" not allowing for any of the old lieing monitor/TV under plastic blezel at corner to edge of glass tube. (Always better to use cm than inches on monitors (& maybe TVs ?), to avoid the industry lies.)
