phillyboy Posted January 4, 2016 Share Posted January 4, 2016 New poster, but I have been lurking for awhile trying to see if I want to do this eGPU setup to get back into Mac-land. However, I own a ROG Swift PG278Q already, and while I know that g-sync is not supported in OS X I was wondering if people who own this monitor are still able to turn on ULMB while in OS X with their NVIDIA eGPU connected to the monitor? For the games I play there would be a plus to at least having ULMB enabled while playing instead of rebooting to Windows to get all the features of the monitor. I am also asking because it looks like AMD cards cannot enable ULMB if they were connected to a PG278Q, which seems counter-intuitive since ULMB seems more like a monitor-only feature. It looks like there is some sort of a driver/software check going on with the monitor/g-sync module and computer that prevents AMD cards from enabling ULMB on this particular monitor. I don't have the full path of where I am going, but I currently have a MSI 980 Ti that is connected to the monitor and I was going to look to re-use that for an eGPU setup. Thanks in advance.

Dschijn Posted January 4, 2016 Share Posted January 4, 2016 If ULMB is sth you can activate in the monito itself and not the driver, it should work. Still I would recommend to reboot into Windows to get a much better performance in the games. Quote Link to comment Share on other sites More sharing options...
