Dual Monitors

[FrancescoAR]

Hi guys, I connected the HP 27es monitor to my hackintosh and as you can see in the screenshot, Hsierra shows two monitors, but physically it is only one connected. How can I solve it?

I also tried connecting the second LG Flatron L1930s monitor to the DVI port of my ATI Radeon R9 285 2048 MB video card.

At the beginning of the bios it works, but then Sierra Alta does not send a signal and does not reveal it but provides information as if two HP 27 monitors were connected, but in reality it is one HP 27 connected to the HDMI port. how to solve? Thank you

What version of macOS ? How are you getting that old style 3D dock to work ?

ciao Francesco, are you sure you do not have anything inserted in the other hdmi ports? if yes remove all the checkboxes from your clover config graphics section and remove the ig platform id, remove the fb name and install lilu.kext and whatevergreen.kext rebuild kext cache and reboot

Thank you. Not another hdmi port. Only one hdmi with HP 27es connected. Tomorrow I will carry out the attempt that you have suggested to me and I will let you know the outcome. For me it is now late in Italy it is 22:30. Thank you

Ok I partially solved it. In clover in the start options of the graphic injector I removed the "InjectATI" box as you see in the screenshot. Now registered the monitor but it only works as a screen clone. How to solve? Help!!! thank
