I try to use IDA to locate the offset of 280h and 1e0h you’ve mentioned, and compare the context hex value with one of your patched file to make sure I find the right place. The problem is, I don’t know anything about disassembly. But my laptop’s monitor is 1280*800, you don’t provide that resolution patch. But as you know, this driver can’t set the resolution properly. So I have to install Windows 8 and use Basic Display Driver and it works fine. God, damn it! My old laptop’s Display Adapter(Ati x1300) has some problem, if I install it’s driver to fully enable it’s hardware features, it would cause BSOD. now you can get the respective resolution according what files you used. Take a file you wanted from the compressed file, go to C:\Windows\System32\Drivers, modify the files security, take the ownership from TrustInstaller to Administrators, and assign Administrators to Full Access. It’s best to do a check in device manager, it’s using basic adapter driver.ģ. reboot, and you should get a very low resolution at 640*480( if you are remoting). skip this if you are using Basic Adapter Driver already. Change your current adapter driver from a buggy driver, e.g. PAGE:000000000001859E mov qword ptr, 0A00hįor your convenience, I have patched 圆4/x86, and there are 3 resolutions mod in compressed files. After a few googling, 1366*736 is most used resolution, and 1600*900/1920*1080 is used in recent HD monitors.Ģ. PAGE:000000000001852C CODE XREF: BASIC_DISPLAY_DRIVER::FallbackStart(_DXGK_DISPLAY_INFORMATION_PLUS_EDID *,uchar) 141p PAGE:000000000001852C private: void BASIC_DISPLAY_DRIVER::GoToHeadless(enum _BDD_HEADLESS_REASON) Use IDA, according the function names, we can easily reach here: And actually, we usually put our servers, HTPC(it become headless if you switch to other source in your TV) in this mode.īy modifying the default value in BasicDisplay.sys, we can change this. However, as its name, basic display adapter, it provides 640*480 when boot in headless mode, that is, no monitor is attached to a systtem. And you can always use it when your graphics adapter has a buggy driver. This driver is used during installation, a suitable driver is not found(always old adapters no longer supported by manufacturers), safe mode. Microsoft has introduced a new out-of-box driver, Microsoft Basic Display Adapter Driver.
