Viscaria Posted June 19, 2017 Share Posted June 19, 2017 I've got Sierra installed w/ Clover on my HP Z1 AIO workstation. Without video acceleration the internal screen is recognized just fine. With Inject NVidia set to true I get video acceleration, but only the external monitor works. I got a a rom dump for this card from techpowerup.com and also dumped the rom myself, both produce the same NVCAP in NVCAP Maker: 0400000000000700000000000000000700000000 Using this NVCAP doesn't change the results, still no internal display signal. actually blacks out both displays. For completeness, here is the original NVCAP from IOJones: 0400000000000100fe0000000000000700000000 Any tips on how to tweak this to get the internal display to work? I'm not sure if it's LVDS or eDP, does this make a difference? I have a source for a cheap Kepler based k2000m that would work in this machine. Any idea if that should be more likely to work? System Specs: HP Z1 AIO Workstation (gen 1) Intel Xeon E3-1245 V2 8GB DDR3 Quadro 1000m (mxm card) Link to comment Share on other sites More sharing options...
Viscaria Posted June 19, 2017 Author Share Posted June 19, 2017 Thanks, Hervé. I gave this a try and I'm still seeing the same issue. To be clear, the internal screen isn't even showing up in System Preferences, it's like it's not even connected. I looked at the ioreg output and there is a Display-A and a Display-B, so it does seem that the OS can tell at some level that there are two ports (btw, the internal screen is eDP, just figured that out in Linux). Since EDID Inject didn't work, I also tried injecting a CustomEDID (which I dumped in Linux), this also didn't help. Link to comment Share on other sites More sharing options...
Viscaria Posted June 20, 2017 Author Share Posted June 20, 2017 I've attached the requested files. In my current config.plist I'm using all the settings you recommended. Tried each suggested SMBIOS iteration and still no change. I've commented out my custom EDID since it wasn't helping. I picked up that Kepler card, I'm going to install that now and see what happens.

Viscaria Posted June 20, 2017 Author Share Posted June 20, 2017 …and the Kepler card was DOA, at least it was only $10. Link to comment Share on other sites More sharing options...

Viscaria Posted June 21, 2017 Author Share Posted June 21, 2017 Sorry, that dump was from IOJones, I didn't realize it doesn't have equivalent output to IORegistryExplorer. IORegistryExplorer output attached. I tried each iMac13,1, MacBookPro10,1, and (for good measure) MacBookPro6,2 both with and without with Board-ID of Mac-C3EC7CD22292981F. Just went through again and tried each of these permutations without the NVCAP. Every attempt had the same result of only getting video on the external display (except MBP6,2 which actually blacked out both screens). The current plist version (edited w/ Clover Configurator 4.43.0, no NVCAP, Ivy Bridge iMac, custom board ID from above) attached. Thanks again for all your help. z1.ioreg.zip config.plist.zip Link to comment Share on other sites More sharing options...
