Windows 10: Win 10 Upgrade Created Two Displays on One Screen Laptop
Win 10 Upgrade Created Two Displays on One Screen Laptop
Hi all, I upgraded my old (2010) HP Touchsmart TM2 to Windows 10 because I upgraded my other 3 comps, so what the heck, right? I have switchable dual graphics cards, (Intel Core 2 Duo SU9600 , ATI Mobility Radeon HD 4550) and on final installation reboot, it said it was upgrading my graphics driver. When it booted after that, my screen was black. So I blindly logged in, and found that pressing the Windows+P, then down arrow/enter keys, which selects your displays, brought the screen up. It was on Second Display Only when it worked.
However, the brightness setting does not work for the 2 screen. It also doesn't work when I choose the 1 screen. When I press Detect, it comes up with the 1 and 2 screen, and two other boxes that say not detected. The brightness setting only works for a second when I choose Extend This Display, then the screen goes black, but I can't remember which screen has that option. I can't even figure out which display number goes to which card. It's almost like Win10 thinks the two graphics card are two separate monitors and neither are the actual laptop screen. I don't have other monitors plugged in. Can anyone help me work this out?
So I disabled my discrete ATI card. This brought the screen back to " PC Screen Only" which allowed me to set the extremely sensitive btightness slider up a little. But my orel Painter was lagging so much, I turned the discrete graphics back on. I haven't tried disabling the Intel onboard yet. Doesn't anyone have any thoughts?
Try disabling the onboard Intel graphics.

Does it have a special function key to switch the graphics from internal to external? On my laptop its the Fn and the F8 or F9 key. I'm on my desktop PC at the moment. If it has that function toggle it and see what happens.

Sorry if this topic is related to Windows XP, rather than Windows 10, but I would like to hear experts' opinion as I cannot find any working solution at Google and YouTube contact is inexistent.

I upgraded to Windows 10 on Sunday and all was well. When I went to log in on Monday the laptop screen was completely black. It sounded like it was working ok but I couldn't see anything (not even the cursor).
