Dear all,
I have the following problem on a Windows 7 Home Premium, Intel i5-2520, 4GB RAM, system.
For some reason windows and/or intel’s driver for the HD3000 card doesn't remember the manually set refresh rate. Every time the laptop is tuned off (including, hibernation, restart and standby states) the refresh rate is set to 40Hz. I tried several times to set it to 60Hz and it works perfect until next power event. This is very annoying as every time it has to be set manually otherwise one can see the screen’s flickering on a grey/black background.
I’m referring above to the notebook’s internal “built-in Display”. I have never experienced a similar behavior with any PC system.
Is there a registry key or something else to force the driver to use 60Hz?
One more question: is it normal to wait several seconds until intels driver is called from the taskbar icon. It doesn’t respond immediately.
The computer was bought in November, Sony Vaio SA series.
The above described problem occurs with both, the default driver which the system came with and the latest Intel driver (downloaded 4 days ago).
In the system properties the Display uses the default MS driver.
Thanks you all in advance!
