- Many thanks to all who replied to my original post, giving me advice on what
- card + monitor to buy. I ended up buying an Orchid Prodesigner IIs card with
- a MAG MX15F monitor.
-
- At first I was completely amazed by the monitor. I never dreamed any monitor
- would give me this much control over the picture. When they advertised edge
- to edge viewing, they weren't kidding. Basically, the monitor is a multisync
- monitor with a little 7 segment L.E.D. display. When you switch to a graphics
- mode you are going to use, you can stretch the picture and move it around until
- it fills up the entire screen. Then, you save it to a particular mode (1-8).
- Then, whenever you switch back to that graphics mode, the monitor will recall
- your settings and display the mode number on the 7 segment display.
-
- Forgive me for boring you if you are used to this kind of thing, however I was
- completely amazed and wanted to let everyone know that for $200 you get much
- more than simply an extra inch of screen.
-
- THE PROBLEM:
-
- The two highest clocks on the IIs are 65 and 80 MHz. Whenever I use
- the 80 MHz clock, I get tons of snow on the screen (kind of like when
- you wrote directly to the video memory in the old CGA displays). That means
- that when I try a 72Hz vertical refresh 1024x768 mode, or a non-interlaced
- 1152x900, it's unusable. 1152x900 does work in interlaced mode with the 65
- MHz clock, however.
-
- Now, even stranger: I called tech support at Orchid. The person I talked
- to said that the IIs does not support 72 Hz refresh at 1024x768, only 70 Hz.
- Moreover, he said that the highest clock rate on the card was 75 MHz for
- this, rather than 80. Thus, either Xfree86 is not reporting the correct
- speed, or there is a 75 MHz clock on the card not being reported.
-
- QUESTIONS:
-
- Has anyone gotten 1024x768 at 70 or 72 Hz vertical vefresh, or 1152x900
- non-interlaced under Xfree86 with an Orchid Prodesigner IIs?
-
- Has anyone experienced anything similar to what I'm seeing?
-
- INFO:
-
- Here are the modes I used:
-
- "1024x768v" 80 1024 1032 1152 1384 768 784 787 823
- "1152x900" 80 1152 1160 1376 1548 900 920 940 948
-
- Thanks in advance for any help.
