Would installing SwitchRes X and changing the hertz fix the issue. Since it's an obvious software problem that apple isn't dealing with.


I just installed SwitchRes X and created an array of refresh rates at 1280x1024. I don't have the issue at resolutions lower than that. The problem dropped dramatically at 58Hz and disappeared completely at 57Hz.

So SwitchRes can work, at least for some monitors. However, I'm a little annoyed that we have to resort to buying a 3rd party utility to fix this. Mad


what monitor is this, CRT or an LCD. is it DVI or VGA?

It is a Princeton VL 1916 (19" LCD) using the DVI connection.

Hello,
I found a solution for 1280 1024 resolution.

This is ***freeware***, and much more convenient to use than SwitchResX...

go to http://www.pyehouse.com/lynn/cscreen.php
download cscreen and run cscreen -d 32 -x 1280 -y 1024 -r 57
This adds a 1280 1024 @ 57Hz resolution.
This solves the DVI fuzzy lines problem, no more lines or dots appearing, nice DVD playing....

Instructions...
1. Download the cscreen application
2. Mount the cscreen disk image by double-clicking on the "cscreen.dmg" file that you just downloaded
3. Open the Terminal (located in Applications/Utilities) and enter the following command:
sudo cp /Volumes/cscreen/cscreen /usr/local/bin/
then hit return (you will be prompted for the administrators password)
****
If you get the message "directory /usr/local/bin does not exist" enter the following commands:
sudo mkdir /usr/local/bin/
then...
sudo cp /Volumes/cscreen/cscreen /usr/local/bin/
****

4. If you are comfortable using the Script Editor, you can easily create a script.
Here's the single line of AppleScript code....

do shell script "/usr/local/bin/cscreen -d 32 -x 1280 -y 1024 -r 57"

5. Open the System Preferences and choose "Accounts"
6. Select the "Startup Items" tab and then hit the "+" button
7. Locate and highlight the AppleScript you just made, then hit the "Add" button.
8. Quit out of System Preferences

Everything should be installed now. The next time you reboot your computer the AppleScript will run, and your monitor will be automatically set!


This worked for me, I made several things i think this is how I made it looking at indications on several forums. I'm new with scripts so correct me if I made a mistake in my indications.

Hope this helps, and if you see a solution for 1600*1200 let me know...
all the best,
olivier
