Got my G502 hero a couple of days ago. Bought it primary for editing video/photoshop cause of amount of buttons. Tried to play DOOM 2016 with it. IT FREAKING HEAVY comparing to my main g403 mice. Absolutely useless for FPS.

Good job! I don’t think i wouldve been able to lead you that far

I MADE IT!!!!!! Only 8 hours of searching and trying and here we go!

Start regedit. (You need administrator access under Windows 7, 8 or 10.)
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video
Under Video you'll see a number of sub-folders with long names like {B1E0FF3B-2B31-4B0D-8B9C-B09BBB60CB07}. Each of those has a sub-folder called 0000. Most of the 0000 folders will be nearly empty, but one of the 0000 folders contains hundreds of entries that have names of programs in them (e.g. _3DMark05.exe, playNow.exe, etc.). Find that one.
In the 0000 folder you found in the previous step, right-click, and from the context menu, select New, then Binary Value.
When the new key is created, change its name to DevicesConnected
Right-click on the new key and click Modify...
A dialog box will pop up that says "0000" -- it's waiting for you to type data.
Type the following keys acourding to your specific configuration:
2x digital monitors -> "00 00 03 00" (0x30000)
2x analog monitors -> "03 00 00 00" (0x3)
digital/analog -> "02 00 01 00" (0x10002)
analog/digital -> "01 00 02 00" (0x20001)
Although I have only my TV connected to this PC I used the first one "00 00 03 00"
You can disable the unused "monitor" later by not cloning or extending your desktop to that screen.
Click OK, exit RegEdit and reboot.
