Horizontal jagges in FSX

Hi,
I've searched everywhere on the net, but still I cannot fix my problem.
The problem started after some PC changes.. mainly changing from CRT to 22"TFT monitor (prolite E2202WS).
This is my system..
Windows XP SP2
AMD 6000+ processor
GA-MA55-S3 motherboard
4GB DDR2 (only 3 is used because of WIN XP)
XFX-8800 GTS 320mb graphic card.
FSX runs pretty well with some tweaks (FSX.cfg).
I use several mods like level D's 767, GEX, FEX, Nicks sunfix and my Traffic X (with FS2004 AI aircraft for better looks).
Now my problem.. distance textures starts shimmering and moving.. usualy only the horizontal textures.
This happens with runways, buildings, airplanes etc..
I hope this picture will clarify it a bit, check the runway that is the furthest away. If you look closely you see that the linns are jagged.

I already tried Nhancer, but no joy..
I used several FSX settings I found on the net.. but the problem is still here..
Hope someone can help...
Dennis
