Part I - RESOLUTIONS
TIP:
When experimenting with resolutions, while searching for possible performance solutions.
I.E 1280x1024 = 1.310MP & 1440x900 = 1.296MP.
Therefore, if you find acceptable results for a video card &/or PC monitor/HDTV at 1280x1024, then you might very well have comparible results at 1440x900.
So by using the RATIO FORMULA & DECIMAL CONVERSION below any number close to the decimal for the WS ratio you want, should work pretty well.
The list is sorted by the RIGHT side resolution number WWW X HHHH. (W=Width, H=Height)

RATIO FORMULA & DECIMAL CONVERSION
WIDTH / HEIGHT =
1.25 = 5:4
1.33 = 4:3
1.50 = 15:10 WS
1.60 = 16:10 WS
1.66 = 5:3 (or 15:9) WS
1.77 = 16:9 WS

SDTV / EDTV / HDTV Specifications:
1080i/p HDTV format is 1920 X 1080 pixels.
720i/p [aka HDTV & SDTV (S=Super) or EDTV] is 1280 X ~720 (768).
480p EDTV (E=Enhanced or Extended) [may/may not be widescreen] is 640 X 480 or 704 X 480.
< or =" 420i" s="Standard)" style="font-weight: bold;">old cable/Beta/VHS/over air = ~240 to 320)
HD vs ED vs SD
Refers to the resolution or number of pixels used to represent a single video image frame. Standard Definition refers to having about 350,000 pixels per frame &
High Definition refers to having about 2,000,000 pixels per frame, (or about 6 times more than SD). Therefore, 7201/p is NOT True HD.
I will add more information once I or Dougofthenorth receive them.
