Hi
I’ve googled for your Question and found this table:
ColorDepth 640x480 800x600 1024x768 1280x1024
8 bit 769 771 773 775
15 bit 784 787 790 793
16 bit 785 788 791 794
24 bit 786 789 792 795
So I think the answer for your Question would be: 795
I haven’t tested it but i will this evening.
Hope this helps
Greetz
