اگر یک سر به بخش گوشی های HTC توی Gsmarena بزنید میبینید که اکثر گوشی های این برند 65k هستن.

Windows Mobile 6 (and WeCE) supports pixel depths of 1, 2, 4, 8, 16, 24, and 32 bpp. (Source: msdn.microsoft.com)
16bits = 65k colors, 18bit = 262k colors, 24bit = 16,7m colors.
So, WM doesn't directly support 18 bit colordepth (262k). Are we fucked? No.
To still use that amazing screen you could either:
A) Run WM at 16bpp, then use a standalone graphics chip to enable dihtering and smooth out color transitions to take advantage of the 262k color palette of the screen.
B) Run WM at 24bpp, then use the same GPU as mentioned above to take the color depth down to 18bpp in the framebuffer before writing to the screen.
It is confirmed that the X1 has an onboard GPU from ATI. They can easily use it to do one of the two above and therefore utilize the full 262k colors of the screen. The reason most WM phones use 65k is that converting the framebuffer takes CPU cyles. Using GPUs takes more power and costs more.
