All, in the test1 of libdlo, it configs the bpp to 24 when it sets the mode. With my monitor (It is not in front of me now, i will get the model number later if need), if I try to set it to 32bpp, the get_mode function will always return 0 bpp and the test will fail. I'm wandering if anyone has been able to use 32bpp on a monitor? Thanks Yi
