azhxc721 Posted November 20, 2015 Share Posted November 20, 2015 Hi all,So I have done some pretty extensive searching and can't seem to find a straight answer on if/how this is possible.I am currently trying to use my 46" (I believe) Panasonic Viera TV to display my mac running OSx El Capitan. I can get it running just fine using the VGA port, but I have a DVI to HDMI converter, and have been running my Windows partition using that without any problems. When I try to hook it up to mac, the OS freezes.Everything else is running fine! Would love the help if anyone has any suggestions. Current Machine Motherboard - ASUS P5QC with custom DSDT Processor - Intel Core 2 Duo 4 core @ 2.4Ghz Video Card - EVGA e-GeForce 9800 (uses 980 chipset) Link to comment Share on other sites More sharing options...
d620osx Posted November 20, 2015 Share Posted November 20, 2015 Hi Not sure but could be a graphics card issue. I have a hd 5450 and a gt210 both run fine using a Hdmi to dvi connection to my dell monitors. 1 Link to comment Share on other sites More sharing options...
azhxc721 Posted November 20, 2015 Author Share Posted November 20, 2015 I have tried installing the NVIDIA web drivers and know that they are working but on boot it says that I am still using the native OS X drivers. Every time I switch it restarts and then does the same thing. I am really hoping this isn't stemming from an unfixable issue with the card.

I am not sure why, but yes, the UI will keep saying that it's using the OS X drivers no matter what. On the other hand, it obviously is not, because graphics work fully accelerated. I suspect the UI is looking at some NVRAM setting which doesn't get set correctly, but the drivers select themselves based on the nvda_drv=1 bootarg At least that is my experience on a GTX970 1 Link to comment Share on other sites More sharing options...

I have it injecting NVIDIA as well as using the nvda_drv=1 bootflag, works fine for DVI out to a DVI monitor, as well as DVI to VGA conversion. My TV onlu supports VGA and HDMI, and my DVI monitor broke, hence the hang-up and need to use HDMI rather than VGA in order to still have a decent looking display. If anyone else has any suggestions, the help is much appreciated. Thanks again everyone! Link to comment Share on other sites More sharing options...
