Looking for a method to use my rMBP GT 750m as a desktop replacement.
Apple advertises the system as "able to drive 2x displays at 2560x1600" however, I have been able to get 2x 2560x1600 (dual MDP) and 1x 1280x800 (over HDMI). Given the system can drive 2x 4K Displays (~16.58 million pixels), it should have no problems in handling 3x ACDs (~12.28 million pixels).
The only issue is the lack of compatible ports to connect these ACDs.
Few options I have researched but not yet attempted:
- HDMI to DisplayPort (up to 4K compatible) -> DisplayPort to Dual Link DVI (active adapter)
- Thunderbolt Dock without eGPU however, it is compatible with 1x MDP (2560x1600) and 1x DisplayPort (up to 4K)
- eGPU options, couldn't find an option under $550 CAD ($400 USD) budget incl. cheap ~$50 card that can drive a 2560x1600 display
Options tried:
X HDMI to Dual-Link DVI with supposed compatible pin layout (limited to 1280x800)
X Patching NVIDIA GT 750M driver to allow for pixel clock speed > 165
X Custom resolutions in Windows (2560x1600 at 24/25/30/35/60 Hz tried) and Mac (2560x1600) tested, black screen
Turning to the community for ideas in resolving this issue. Thanks in advance.
