LCD Flicker. And windows won't keep changes to the display settings!
Dear experts,
I've seen some really strange behavior lately, like I've never seen before. I have a Dell 4600, with an Nvidia Geforce 5200 card in it. To date, I've used a simple CRT monitor from Dell. But this week, I bought an LCD screen from Sony. There was some flicker. So, I downloaded the latest drivers and everything from NVidia, and installed everything. There still was flicker. So, I decided to compare. I also have a Sony laptop, and an LCD TV. I use my Laptop to play DVDs on the TV. I took the 4600 downstairs, and plugged it into the TV. It had weird display setting when I logged in, but I changed them and it worked fine. No flicker on the TV. I also brought the LCD display downstairs, and tried it with the same 4600 computer there. Interestingly enough, no flicker. So, what is causing the flicker with the LCD? I also have another desktop, with an ATI card, that sits right beside the 4600, and it doesn't give flicker with the LCD. (I use a KVM switch to move between computers.) So, the location makes a difference. Upstair flicker downstairs no flicker But, why would I also not get flicker with the other machine, right beside it? Strange! The machines are XP/Linux dual boot. On the 4600, it also flickers in Linux. I read that perhaps the power source might have something to do with it. So, I ran an extension from the main floor upstairs. No difference. So, if that is not enough, today when I boot the 4600, the video settings are off. They are the same as they were with the LCD TV. I change them back. And when I reboot, they go back to what they were with the LCD TV! What a bother! Questions 1) How do I set the video settings so that they stay as I set them? when I reboot, they are the same as what I set them to. 2) Any ideas on what is causing the flicker? |

What refresh freq did you set the GeForce card up to?

Check the refresh rate in Display Settings of Control Panel. It is more
than likely set to 75 or so. Change it to 60 to stop the flicker. wrote in message oups.com... Dear experts, I've seen some really strange behavior lately, like I've never seen before.

With the ATI drivers the settings you'll see without forcing the issue will
depend on the .INF file for the monitor. So the next question is, are the settings ones that the monitor supports? Whether or not the GeForce works this way it's best to have the proper .INF file. If the monitor didn't come with one get it from MFG website. If Windows doesn't detect the monitor change check Device Manager to see what the display is set for. Install the correct .INF. Display issues are almost always driver issues. It certainly isn't necessary to cross post something so simple to 4 groups. Start with the video card group. Not that familiar with Nvidia but seriously doubt it's worth repairing anyway. Would make much more sense to get a newer card if it had a hardware problem. "nappy" wrote in message et...

Change the refresh rate to 60 hz to stop the flicker.
That was the solution! Geez, you are good! Thanks a lot!!! On Mar 15, 2:28 pm, "Completely Lost" wrote: Check the refresh rate in Display Settings of Control Panel. It is more than likely set to 75 or so. Change it to 60 to stop the flicker. |

I replaced my very old KVM with a new one just a few days ago. My old MAG 17" LCD display is the one which I switch. It's a 75 Hz unit and for some reason when I switched it to the newer PC its driver kept getting reset to 60 Hz, which causes a dazzling effect rather than flicker. The two PCs use the same ATI x1300 256 PCIe card. After resetting the scan rate to 75 in CCC for at least the fourth time, it finally took and the display has been fine since. |

The KVM is not properly switching the monitor ID lines, only the video lines. I think there is a way to specify that the driver ignore the Monitor ID and just use what you specify... |

You may be right, but there is no driver with this KVM. There is an app to allow click switching, as the chosen "scroll lock" hot key is a problem on both of my wireless keyboards which double up that function on a key. I don't use the app, I've chosen to place the KVM controller box on the floor and tap the large, top-mounted action button with my right foot. The USB keyboard is also seen by each OS as coming and going, and that really should not happen either. I'm going dingy from all the dings;-) |
