osx9010 Posted January 30, 2018 Share Posted January 30, 2018 Hello, I have a dell Optiplex 9020 and followed Jake Lo guide. Thank you by the way. I'm on el capitan and running the 9020 bootpack. Using the stock 2 display port output. I have 1 x 1080p monitor connected to the DP using a DP to DVI adapter to DVI on the monitor. The other monitor is a QHD monitor. It's connected DP to DP. The problem, is the QHD monitor sometime work on a cold boot and sometimes NOT. When the QHD monitor doesnt work, the led light is on and OSX see it but the screen is black. I will have to turn off the QHD monitor and turn it back on and then it will work. The regular 1080p monitor above always works. What I'd like to do now is get rid of the 1080p monitor using dvi and have two QHD monitor with DP however it will not boot. If I only have the QHD monitor plugged in, it will boot loop. So I have two problems. 1 is I have to turn off and on the QHD monitor in order to get it working when another DVI monitor is also plugged in. The other problem is boot loop on only 1 QHD monitor. Please advise. Link to comment Share on other sites More sharing options...

osx9010 Posted February 1, 2018 Author Share Posted February 1, 2018 Hi, I'm wondering if maybe the boot pack is NOT suppose to support QHD but i'm able to get QHD resolution? Please see my monitor screenshot attached Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted February 1, 2018 Administrators Share Posted February 1, 2018 if your running high Sierra there are issues with dual monitor support. or it can be an EDID issue maybe you can try switchresx app. Link to comment Share on other sites More sharing options...
