Incorrect resolution; *but* GFX card is detected correctly (nv 210)

12 December 2013 - 08:25 PM

So I've managed to get my system running nicely; even dualbooting with Mint Linux! Audio is crystal clear and pretty impressive really, everything is functioning correctly - you could even say flawlessly, it's perfect.

 

Except for my Display; it's at the wrong resolution - and even aspect ratio.

 

Now I say Display as my graphics card appears to be detected correctly and I'm not seeing any adverse performance issues regarding using it. (I can stream videos, play videos and do multiple tasks that include graphics intensive activity without any performance issues)

 

Here's how my Graphics Card is displayed in System Report:

Everything appears correctly. Note this is after implementing an EFI string - but prior to the EFI string it was appearing correctly too. (This EFI string was just something else to cross off the list so to speak)

 

Yet when I go to About This Mac I see this, "spdisplays_display"...

Delving in to System Preferences, I can see that even going to "Scaled" only provides me with the option for 1024x768...

I've tried "Graphics Mode" too, which I thought would do the job. I've tried output from both DVI-I and VGA. (BTW, Surprisingly VGA does indeed work through the 210 in Mavericks - it's only during installation that it results in a black screen with output incorrectly being sent via HDMI when you have all default NVD* kexts)

 

Now if the Graphics Card is working correctly, and "Graphics Mode" isn't providing me with any luck, is it possible to extract the VendorID and ProductID from the Display and do something with these? (Do what? I have no idea! I just remember doing something similar a few years back, but that may have been with a Linux distribution actually..)

 

Failing that, any ideas? I did some searching and see that this is an incredibly common side effect of other issues - but from what I've seen, most cases usually involve incorrectly recognised Graphics Cards?

 

Currently running 10.9.0 on a system utilising 8GB of RAM (2x 4GB modules), an intel i3 at 3.3Ghz and a Gigabyte H67N-USB3 motherboard. Current graphics card is a nVidia 210 1GB - although I've just realised I have an 1GB nVidia GT510 sitting in my desk drawer that may perform a little better..

 

Cheers guys (and gals!) :)

Forcing DVI output during installation (Nvidia 210) // Black Screen

09 December 2013 - 11:09 PM

I'm currently trying to get Mavericks running on some parts that I quickly ordered - I'd returned my MacBook Pro to my previous employer before realising I had a few things I'd been meaning to do.

 

So I checked the HCL and bought some fairly recommended components: including this graphics card, the Nvidia 210.

 

Initially I tried installing from a boot media configured via dd in linux - and I could boot in to the installer fine.. once I'd removed some of the NV* .kexts. Prior to that I would get a black screen.

 

Well, due to other issues with that install media - I downloaded a copy of Mavericks from the App Store today (whilst at work) and quickly threw together a new USB installer using #####. However that dreaded black screen has come back, and I'm pondering whether there is a better way to remedy it than just removing a lot of kext files?

 

My understanding is that Mac OS X is correctly identifying the card as having a HDMI port, and automatically sending the output to this - neglecting the DVI + VGA ports. I'm using DVI though!

 

Am I barking up the wrong tree by reading about NVCAP? Or should I just be looking at removing the .kext files? Maybe I'm wrong all together! I've seen people discuss solving this via custom EFI strings and other mechanisms - but these are primarily post-install fixes right? I'm just trying to get through the installation itself right now!

 

Cheers guys
