I have been running two LTSP servers (one each at separate buildings). 
One server is running LTSP 3 & one is running LTSP 4.
Both use the same "thin clients" ( a Pentium-3 pc without hard drive ) 
and monitors ( Dell LCD E15FP). The clients have onboard video  output 
based on Intel 815 chip. Both systems have been happily running screen 
resolution of 1024 x 768 on client monitors.

This summer I replaced the version 3 server with a version 5 server. The 
monitor on the clients now display only at 640 x 480. I have checked the 
lts.conf file and both servers have the same configuration:

 #Video drivers for terminals
XSERVE R = auto

All the other lines in that section are commented out with the #. Also 
all of the "Sample Mode" lines below are all commented out with #.

I have experimented with uncommenting (one at a time), each of the 
listed sample modes. I get one of two responses for all that I have 
tried: either terminal screen displays something along the lines of 
"Display not supported" or I get "non synched video" with rolling and no 
discernible display.

Has anyone else experienced this?
What is the fix?
