- RESOLUTION (WELL SORT OF):
-
- This is my third post on this subject. Due to some helpful
- suggestions, I ran the ATI video driver install program and used the
- "custom" driver instead of the "crystal scan 1572fs" driver. As soon
- as I brought "custom" up at 1024x768 @72Hz the problem was obvious.
- The "custom" configuration provides a rectangular box around the perimeter
- of the screen, to facilitate centering. This box was folded over on the
- left side of the screen exactly where the vertical bar appears.
-
-
- Methods of solution:
- 1. under "custom" 1024x768 @72Hz - adjust the displayed box (with the
- commands given on the screen) to be centered.
- 2. under "custom" 1024x768 use less than 72Hz - the problem did not appear
- at all at 60Hz.
- NOTE: This explains why some monitors do not have the problem. I.E.
- my friends NEC 3fgx only runs at 60Hz. It also uses a different driver
- though.
-
- Notes:
- 1. I talked to an ATI tech and he believes the problem is gateways
- version of the ATI bios, or their "crystal scan 1572fs" ATI driver.
- 2. Gateway didn't seem interested in solving the bios or driver
- problem. Basically they said, if the "custom" driver works than
- the problem is solved. I guess it is.
- 3. At this point I am going to keep the second Crystal scan 1572fs
- monitor, and hope that it is going to be reliable. The first one
- had occasional screen flashes.
