Hello VOGONS memebers!
So, if the title wasn't enough ( 😀 ), I'm trying to modify some drivers for my monitor to work under XP. For my main rig (which is both a Windows 10 machine as well as an OP XP machine, you know, so that I can run Need for Speed: Hot Pursuit 2 at over 500fps, and F.E.A.R. at around or over 100fps, all at 1440p 😀 ), I am using the Dell S2417DG, a 1440p Gsync monitor, and a nice one at that. Dell provides drivers for the monitor, but only for Windows 7-10. However, what I want to do is edit the Windows 7 32-bit driver (probably they are all the same driver, but still) so that I can manually install the driver under XP, in order to try to get the monitor correctly detected as a monitor, and not as an HDTV by Nvidia drivers.
Doing a side-by-side comparison of the S2417DG's .inf file, and that of the Dell 1707FP, which does have an XP driver, the only "key" difference that I could tell between both files are the addition of these lines in the 1707FP's .inf file, presumably needed for installing the driver under XP (both driver's .inf files can be found attached to this post):
[ClassInstall32]
AddReg=ClassAddReg32
[ClassAddReg32]
HKR,,,,%MonitorClassName%
HKR,,Icon,,"-1"
HKR,,NoInstallClass,,1
Now, this is where I need you guys' help. What does this do, is it necessary for XP driver installation, should I be able to add these lines (with maybe some modification) to get the S2417DG's driver to install, and, if that's not enough, is there anything else I should add/remove from the S2417DG's .inf file to get it to work?
I know I could just experiment by myself, but I would like some feedback before I try anything for best effect. 😀
Any help would be appreciated. Thanks!
