I Q251154 står det:
Currently Windows Terminal Services are limited to 256 colors. If you use graphics and photos that incorporate anything beyond 256 colors, you notice loss of color depth and some pixelation of the graphics.
Kombinera ovanstående information med det som står att läsa i Q300698:
Support for Over 256 Colors
---------------------------RDP 5.1 enables you to experience 15-bit, 16-bit, and 24-bit color depth when you connect to a Windows XP-based computer (on condition that the local video adapter is capable of this video depth).
Vilket i mina ögon ger ett ganska glasklart svar:
Windows 2000 har en begränsing på 256 färger.
Windows XP fixar fler färger om grafikkortet klarar av det.
