Please use complete words in your posts to make them easier to understand. Thanks.

According to the spec sheet for your monitor, the native resolution is 1280 x 800 @ 60Hz so that is what you should be using. There are no monitor drivers available, probably because it's old & no longer supported. Whether it's recognized by make/model in Windows isn't important, but using the correct screen resolution is - set it & forget it.

Here's the latest graphics driver for your GT 640:

Thank You for your Reply

Just to help you know better, I had 1440x900 display and didnt had any blurry pixels also this problem started after some vga cable loose connection.
In some other sites it says to turn off the system and remove the cables attached to the monitor and reconnect them after about 10-15 mins, and this helps the gpu recognise my monitor and show such resolutions.

Help me know better? lol.

An LCD monitor has a fixed number of pixels. In your case, it's 1280 x 800. Using anything other than the native resolution will force the monitor to interpolate & it will produce an inferior display.

I see your monitor has a response time of 25ms. I don't know if you do any gaming, especially with a GT 640, but with a slow response time & improper screen resolution, I suspect there's ghosting & blur.

I suggest it's time to upgrade to a more reasonably sized screen (20" or larger) which supports 1080p, has a response time of 5ms or better, & HDMI input.
