Heavy Flicker & Unfocus Problem

Based upon prior posters comments, there is a good chance that it is the graphics card.


Odd 7MC flickering issue - NVIDIA driver related

I assume that your specs are up to date.

I remember something when I studied for my Vista exam, one of the questions mentioned finding the default ideal refresh rate and screen size for a monitor and setting your desktop to match. This was to cure screens that loose focus.
What monitor do you have? Please set it to the manufacturers recommended settings and set your graphics card to match.

EDIT: Other thoughts-
- Also check your cable and all connections and remove any electrical interference
- If you are using a KVM switch ensure that it has enough power.
- Try turning Aero off and see if the problem continues
- I know you mentioned drivers, did you get these from Microsoft update or the manufacturers website, go with the latter if you chose the former :)

Have you tried uninstalling both the display adapter and monitor in Device Manager, then let Windows rediscover them on startup?
Just a thought.

My current monitor is the LG W2343T, it is currently running at 59Hz when the default is 60. I try to change the refresh rate both in the Windows advanced screen resolution window and the nVidia control center. Whenever i change the refresh rate to 60Hz, it drops back down to 59 after the Apply. My monitor settings are currently default and so is my graphics card. I got my current drivers from the XFX manufacturer site. Aero has been off for a long time.

I'm not sure why it reverts back to 59, especially since you everything set to 'native' resolution (1920X1080 pixels). This isn't an issue I've ever come across before in many years of IT support (with the exception monitors just failing, which still fits). What I read on the web provides no solid info for your 59Hertz, some readers swear that this causes their monitor to flicker, others say that Win7 is correct and that XP rounds up to 60. Yet others say that some applications play-up when the refresh rate is less than 60.

Other thoughts:
- Turn everything off, unplug the power and give your graphics card a little clean, same goes for any cables and ports from the card to the monitor.
- Look for correct drivers for your monitor, it's common to forget about this as the default windows drivers usually work great. I tried to get you a link but the LG website is at snail pace at the moment.
- Take a look at this Screen Refresh Rate - Custom for NVIDIA Brand

I tried using the default Windows graphics driver (uninstalled current, removed device, rebooted, installed windows driver, rebooted).

I have the latest version of DirectX 10

I have successfully changed my refresh rate from 59hZ to 60hZ.

I cleaned out my PC and checked un-dusted all my ports.

I tried to install the monitor driver but its only for 32bit.

I tried installing older version Nvida drivers (190 instead of 195)

Nothing has worked.

Here is a short clip that demonstrates what i mean. Im clicking the forum, interacting, trying to change values, and it randomly unfocused. This is not a problem with that specific application. The same problem happens with all applications.
