LCD is blurry

Acer AL2017.
4:3 display
1400:1050
20"

I'm outputting analog from 8mb shared Intel 82845g integrated video to an LCD using a VGA-VGA cord. Various res and refresh settings all produce blurry images and text, with the native 1400x1050 not supported by the hardware. I've attempted screen auto-adjusts using lines and color strips to no avail. Cleartype on/off/custom modes seem to make little difference; text is blurry on and blockish/malformed otherwise.

Before I go out and purchase a cheap DVI card with cable, do you have any suggestions for me? Thanks.

OS?

A quick google search looks like 1400x1050 is supported...

Windows 7.

1400x1050 has no redeeming value for me, it's for informational purposes mainly. Using a monitor testing utility I can see wider more distinct horizontal scan lines than vertical at my 1280x1024. My more subjective observation of text while moving windows across scan lines suggests these may play a part in the nuisance.

1400:1050 is 4:3, the only other available resolution with that aspect ratio is 1152x864, which is also plagued by blurriness.

Patchwork remediation.

1. Moniteste 1 pixel horizontal-vertical scan lines at 4:3 native 1152x864 resolution (leaving clear type off).
2. Screen auto-adjust while full-screen.
3. Close moniteste.
4. Turn on Cleartype, manually set as desired.

Still somewhat blurry, but easier on the eyes without overt scanline distortions.

May be worth checking the monitor to see if it has an 'expansion' option. Turning this off means it would stop scaling up the input and render at 1:1 pixel ratio... which is probably the source of blurring. Unfortunately many monitors don't have this option.

if you can't do native rez you'll never get it sharp.
