CRT refresh rate down to 60Hz

Wim · 03-26-2012, 10:04 AM

The highest refresh rate that is available at 1280x1024 is 75Hz (if the monitor reports this as being supported). The maximum refresh rate is limited by the maximum pixel clock that our hardware can do.

OK, 75Hz would be great, but i can't choose that.
Only available option is 60Hz and there is no dropdown menu to choose from.

What can cause that?

As I said above - "if the monitor reports it as being supported". If you post your log files, this will contain the monitor information and tell me what refresh rates the monitor supports.

Hi,
when i connect this monitor via VGA to laptop it says that it support at this resolution 1280x1024px 85Hz, and on 1024x768px 100Hz and it works at that properties.

But when it is connected via DisplayLink Adapter the refresh rate is reduced to 60Hz even on smaller resolution 1024x768px.

How can I get logs?
