For my external Dell display I'm also stuck with 1024x768. As a work-around, the script below forces the 1600x1200 resolution. I have put the script in ~/.kde/Autostart/xres_fix.sh and done chmod +x ~/.kde/Autostart/xres_fix.sh to make it execute after KDE starts. I guess it could be executed also earlier if put into the right .Xsomething file.
------------------------------------------
#!/bin/sh
# add 1600x1200 resolution for VGA1
# generate modeline with
# cvt 1600 1200 60
# modify resolution only if VGA1 is connected
if xrandr | grep -q "VGA1 connected"
then
xrandr --newmode 1600x1200 161.00 1600 1712 1880 2160 1200 1203 1207 1245 -hsync +vsync
xrandr --addmode VGA1 1600x1200
xrandr --output VGA1 --mode 1600x1200
fi
