- OK, so I got a CTX 1560 multisync monitor. They said it would work with the
- Mac. The book (for what its worth) says it will work with the mac. THe monitor
- works great with my PC.
-
- So I plug it into the mac using the directions that specify. Turn the sync
- switch to off like they say (telling the monitor to sync on green). Fire
- everything up and . . .
- it doesn't sync.
-
- it blinks, flashes, scrolls, crawls, ...
- but doesn't sync.
-
- setting it to sync on sync (which I used for the PC) is no better.
-
- The monitor has frighteningly few controls, so there isn't too much to do
- there.
-
- I tried this both with Quadra built in video and with an 8/24 card.
-
- I tried three additional experiments with to no avail:
- 1) fire the machine up with a 13" Apple monitor connected so that the Mac knew
- what kind of monitor (640x480) was connected, then switching video
- cables between monitors
- 2) use the apple cable, rather than the one supplied
-
- 3) fire the machine up with an apple 16" monitor (get the video board into
- 832x624 mode) and switch cables.
- this works a little better than the 13" settings, which is encouraging
- (it'd be nice to run at this resolution!), but still has the v-sync
- problem
-
- Any clues would be greatly appeciated. CTX technical support is useless (they
- don't speak English very well, and when I finally thought I'd conveyed the
- problem to him, his comment was "why would you want to use a macintosh
- anyway"). I really would like to be able to use this monitor. Even if only at
- 640x480 resolution (which they insist should work).
