IBM PC365 - Display jitter / flicker with Windows 95

Applicable to: World-Wide

Symptom :
IBM PC 365 Series 6589 systems with a DDC (Display Data Channel) capable monitor attached may exhibit jitter and flicker after selecting a video resolution in Windows95 that should provide virtually flicker free performance.

Problem Isolation Aids :
This failure occurs in PC 365 model 1XX and 2XX systems configured with an S3 Trio64V+ PCI video adapter.

S3 device driver versions 2.10.01 and 2.10.02 are affected.

When selecting video resolutions in Windows95 such as 1024 x 768 x 16, the driver does not properly program the S3 adapter to function at the optimal refresh rate required to achieve virtually flicker free performance. The driver may set the resolution and refresh rate to 1024 x 768 x 16 at 60Hz which is not flicker free.

Fix :
Use the S3 Refresh tab to select the appropriate refresh rates for the monitor installed. Access the S3 Refresh tab by clicking the right mouse button on the Desktop and selecting Properties, then select Display Properties. This process allows for the manual setting of resolutions and refresh rates.
NOTE: Setting a refresh rate that the monitor is not capable of may cause permanent damage to the monitor.

Refer to the monitors user documentation for information regarding supported resolutions and refresh rates. If this information is not available, contact the manufacturer or the point of purchase for the specifications of the monitor installed.
