This question set is directed mostly at Scott Hood, because I have not
been able to get accurate information from *anybody*.
With a B2000 with the A2320 and ECS, what resolutions are available at
(1) 15 kHz
(2) 31 kHz
(3) any others frequencies that are supported
I am interested in the PAL specs without overscan.
Thanks in advance,
Phil.

Note that the x200 display modes are non-interlaced and the x400 display modes are interlaced and therefore have flicker. PAL RATES - 320x256 320x512 640x256 640x512 1280x256 1280x512 The same information on overscanning and interlaced/non-interlaced display modes applys. 2) At 31.5Khz: 2XNTSC RATES - 320x200 (double-scanned) 320x400 (de-interlaced) 640x200 (double-scanned) 640x400 (de-interlaced) 640x480 (ECS Productivity mode) 640x960 (ECS Productivity-interlaced mode) * These display modes can also be overscanned * - This diplay mode does flicker. 2XPAL RATES - 320x256 (double-scanned) 320x512 (de-interlaced) 640x256 (double-scanned) 640x512 (de-interlaced) 640x480 (ECS Productivity mode, 60Hz) 640x960 (ECS Productivity-interlaced mode, 60Hz) * These display modes can also be overscanned and all but the ECS modes have a 50Hz vertical retrace time. 3) Additional Notes: The PAL vertical rates are 50Hz unless noted and the NTSC rates are 60Hz I may have left something out so please forgive me if I do!
