When i have either the dell monitor or Sony TV hooked up it will recognize it has a generic pnp monitor. However, if i switch from my Dell monitor to the Sony TV the resolution will stay at 1280 x 1024 (75hz) instead of switching to the Sony TV native resolution of 1280 x 768. BUT, if i go to control panel > Displays > Screen resolution and click the Detect button. The Native resolution of the current display gets recognized.Windows relies on the graphics driver to detect the display change, and the graphics driver relies on the DDC line to detect displays. Either the switch is not switching the DDC line properly, which is probably not the problem because that is a passive switch, or the graphics driver is not handling sudden DDC changes properly. It might not detect a new display without a physical disconnection, so I don't know what can be done about that. If the switch had three ports, I would ask you to try switching to the third unused port for a second before switching to the other monitor. |
