This following list is not mine; I found it from some comp.sys.amiga newsgroup some time ago, but I'll repost it now. I think the original was something like ST vs. Amiga in graphics. [The following Amiga video mode list was compiled by Joe Smith (jms@tardis. Tymnet.COM) and has been reposted for this comparison.] Question: What display modes does the Amiga have? Answer: Lots. Mode NTSC PAL ECS Hfreq Colors Palette -------------------- -------- -------- --- ----- ------ ------- Lores 320x200 320x256 no 15KHz 32 4096 Lores-ExtraHalfBrite 320x200 320x256 no* 15KHz 64 4096 (restricted) Lores-HAM 320x200 320x256 no 15KHz 4096 4096 (restricted) Hires 640x200 640x256 no 15KHz 16 4096 Super-Hires 1280x200 1280x256 yes 15KHz 4 64 (35 nanosecond) Lores-Interlaced 320x400 320x512 no 15KHz 32 4096 Lores-EHB-Interlaced 320x400 320x512 no* 15KHz 64 4096 (restricted) Lores-HAM-Interlaced 320x400 320x512 no 15KHz 4096 4096 (restricted) Hires-Interlaced 640x400 640x512 no 15KHz 16 4096 Super-Hires-Interlaced 1280x400 1280x512 yes 15KHz 4 64 (35 nanosecond) VGA-ExtraLores 160x480 same yes 31KHz 32 4096 VGA-Lores 320x480 same yes 31KHz 16 4096 Productivity 640x480 same yes 31KHz 16 4096 Productivity-Interlaced 640x960 same yes 31KHz 4 64 A2024-10Hz 1008x800 1008x1024 no special 4 16 shades of gray A2024-15Hz 1008x800 1008x1024 no special 4 16 shades of gray Notes: * Some early A1000's did not have ExtraHalfBrite. It is easy to upgrade. * The 2nd 32 colors of EHB mode are restricted. They are the same as the first 32 colors with the red, green, and blue values reduced to one half. * HAM mode (Hold And Modify mode) allows all 4096 colors to be displayed, but has restrictions affecting adjacent pixels of differing colors. [Please also note that the above mode list is not showing their perspective values in overscan, meaning- most of the above resoulitions will increase their X and Y values simply by using overscan. IE: A 640x400 mode can go to 704x440 or higher in overscan. Also note that a new mode has been created via some recent software tricks: 704x440 in 4096 different colors. These are true colors and not "shadings" or "blendings".] -- =<*>=-=<*>=-=<*>=-=<*>=-=<*>=-=<*>=-=<*>=-=<*>=-=<*>=-=<*>=-=<*>=-=<*>=-=<*>= # Bror Heinola # NetMail: # Public BBS system: # # Programmer # heinola@karl.hkkk.fi # Twilight Zone MBBS #
