1366x768 Screen Resolution on WYSE S30

1366x768 Screen Resolution on WYSE S30

Hello!

I'm recycling some WYSE S30 that we've got to make all in one computer (S30 sticken to the back of a screen).... But i'm facing a problem, I don't know how to configure the wyses to 1366x768 resolution!

When i'm logged with an administrator account in the configuration panel there isn't 1366x768 in the resolution choices, i'v got 800x600, 1024x768, 1152x864, 1280x1024, 1440x900 and 1600x1200.

I've searched everywhere but i can't find any information on how to activate custom resolution on the wyse, any help would be wonderfull 

WYSE S30 on Windows CE6, rev.674

By advance, a big thanks!
