I recently purchased a new NEC PA272w on sale and, to make use of its 10-bit per color gamut, I have to change to a new video card. My power supply is more than enough: 850 watts. I was advised to change cards, rather than adding one, and I don't believe I have a spare slot anyway. The instructions call for removing the driver for the original card, shutting down the computer, changing cards, booting, and then installing the driver for the new card. What I don't understand is this: how will the monitor work before its driver is installed?
