Hi All

 

After updating to v10.5.4 on the main system, occasionally I got the monitor flickering problem. Certain dots section of the monitor/desktop have flickering problem with blueish continuos buzzing type. For e.g if I open Safari, the top part which is the menu bar have flickering like those audio frequency image.

 

I reboot to the test system of which is also updated with v10.5.4 and Linux, no such problem. Not sure if it's something to do with Nvinject problem.

 

Anybody encounter this issue before?

Thanks for the advised. I don't think it's a graphic card issue as I don't face this problem in the formated test system of OS X.

After looking at it carefully, I think it may have been a refresh rate issue here. I shall try lower it down to 60 hertz instead of 75 hertz and see how it goes when it does happen again. The thing is it doesn't happen all the time and on and off, it will come back haunting.
