I purchased a 900mx with an HP system on Monday. It's Sony's tube but I have no idea who puts it together for Micron. Regardless, it's a great monitor . . . maybe. After the banality of registering with HP I fired up a DVD. The picture was fantastic until the trailer neared completion. The screen became totally garbled. I exited to the desktop which was a mess as well. Four hours on my own and 2 hours of HP tech support leads me to believe it was a crappy card (nVidia16MBTNTAGP). The strange part is that everything if fine as long as the resolution is set to 640x480x16, every other combination is useless. My advice would be to check on card compatibility before parting with your cash.
