My saga began with Windows Update from Windows 10 1703. After the
usual multiple restarts, the update failed with, "Windows could not
complete the installation...". On the third (failed) try, I noticed the
transient blue screen complaint, "VIDEO DXGKRNL FATAL ERROR".
I was able to Restored Previous Version (1703), but the proper
graphics driver had been replaced by "Microsoft Basic Display Driver",
which appears to be garbage, and forces a flicker-rich 60Hz refresh rate
on my old, nice CRT display, instead of the flicker-free 75Hz I which I
had been using before. Driver roll-back restored old (good) AMD driver,
but Windows Update still failed as before.
Figuring that I could outsmart Windows Update, I sucked down a
current (1709) DVD kit, and did a Manual installation of that from the
DVD. That worked, but now the Basic Display Driver is back, and there
is no old driver to which to roll back. Attempts to install an old AMD
driver fail. Update Driver says "The best drivers for your device are
already installed." I disagree. Manual installation (AMD installer,
8.970.100.7000) fails: "The specified driver was not installed for
matching devices." I presume that Windows 10 does something to prevent
that installer from doing its job.
Thus, Windows now insists on using a generic/lame driver, and won't
allow an older, better driver to be installed. A quick skim of this
forum suggests that many people are complaining about "screen resolution
is messed up" or "1920 x 1080 LOST with WIndows 10 upgrades ", or the
like, so it looks like a trend.
I know nothing, but it appears that some bright mind decided to
replace a whole class of old display drivers with some substandard,
universal mess, resulting in crippling feature loss. People with LCDs
may be perfectly satisfied with 60Hz refresh, but we old CRT users need
the (lost) ability to select something faster. I'd settle for some way
(automatic or manual) to get back to the stuff which Windows Update was
dispensing until this recent disaster.
I'm open to suggestions and/or requests for more information.
