Alright! Joining the choir.
We have an ASUS x53J laptop with Radeon 5xxxx series display card, and it worked fine originally in W10 pro.
BUT now the harddrive died and we had to replace and reinstall Windows, and there just seems to be no way to get that 5xxxx series card working in w10 again.
It works only in MS native 1024 graphics mode, any catalyst ir MS whql ati driver I install ends up in the same way; windows brightness is at zero, basically. You can see something by really squinting your eyes and with a lot of time and guesswork even adjust settings. But it's really totally unusable.
None of the brightness controls, both in Catalyst center and windows itself, have any effect. Doesn't matter if they're at 100% or 20% the brightness doesn't change.
I spent the whole day doing registry hacks I found online and some people apparently got theirs working with, changing certain dwords to zero, but to no avail.
The only way to use the machine is go to safe mode and disable the card entirely via device manager, after which the Windows basic driver works fine.
Any more suggestions to try would be welcome but I suppose it's useless to try further. Too bad as the laptop has a decent i3 and a 250GB SSD drive and would be a good machine for quite a while if the display worked properly.
