[SOLVED] Problem with GRUB splash screen

[blnl]

I'm still using old fashioned CRT monitor , which uses different frequencies for different screen resolution.
GRUB is starting in 1024x768 resolution (vertical frequency is 60Hz). For the proper viewing vertical frequency should be 85Hz.
Due to this frequency mismatch, the picture on screen is distorted and it does not fit the screen size.

Can someone help me to fix this issue?

My menu.lst contains following:

1024x768 splash screen is generated as follows:

Problem solved!

I bought an LCD monitor . Now the low resolutions are automatically resizing to fit the screen.
