It's one of those things that just doesn't seem right. No matter how chep the monitor is you still want it to work right and it simply doesn't. There's really no reason why it shouldn't work with it but you know how tech support can be some times. My system is running a GeForce Ultra which is a pretty high end card. Is your home system a Dell? I haven't tried hooking it up to my dell yet but I would bet that it does the same thing.
So, you are not alone on this, I simply can't believe there aren't more people with this issue. I don't know if you've checked to see what panel you have but I've had this problem with both the AUO and the LG panel.
My wife has told me to ignore it but I simply cannot. In the same vein I don't think we should be expected to simply turn it off.
When you pay good money for something I don't think the solution to a problem such as this should be a "hack". It should work as advertised. This piece of information will become significant latter on. The problem was that sometimes my monitor could not go into power saving mode. I knew that I could fix this problem by just clicking Apply in the Power Options control panel applet and I, also, had figured out that the problem disappeared if I adjusted the inactivity period down to 1 minute.
The problem happens after viewing a Flash video e. YouTube and there is a bug report for this issue: FP So, in the last few days, I decided to finally find the cause and a possible solution for this problem. The tools and references I used include:. Fortunately, it is defined inside winnt.
My next step was to open ntoskrnl. The field was accessed from PopDispatchPolicyCallout. Now, I just had to learn where this pointer goes. Now, I started reading the Windows source code. This function contains a huge switch statement. Now, the question is: Who reads these variables? I installed a memory breakpoint at these variables and within 1 second it was hit! The variables were accessed by win32k! Back to reading source code. First it check if it is time to display the screen saver and then it checks if it is time to turn off the monitor.
How does it check if it is time to take action? This field, probably, holds the timestamp of the last user activity. How does it turns off the monitor?
And what happens next? Well, probably the foreground window calls DefWindowProc and the message is handled internally. By now, I had all the information that I needed. The question, though, remains: Where is the problem? First I thought that it might be a video card driver problem. So, I just wrote a simple Windows application, that posted the above mentioned message into its message loop and… tada… the monitor turned off!
