Tobenone 18 port 120w docking station
Can I use my 27in iMac with an Intel chip and the above Tobenone docking station to display in “extend” mode to multiple 4k or 5k monitors?
iPad, iOS 10
I don't know why it doesn't mention iMacs as compatible, plus the eeding drivers scares me off.
If the built-in Display Support isn't good enough: Dual/Mirroring*2nd Max. Resolution:6016x3384
Details:*This model can simultaneously support the internal display at full native resolution and up to one 6016x3384 (6K) external display at 60 Hz with support for 1 billion colors; one 5120x2880 (5K) external display at 60 Hz with support for 1 billion colors; two 3840x2160 (4K UHD) external displays at 60 Hz with support for 1 billion colors; or two 4096x2304 (4K) external displays at 60 Hz with support for millions of colors. It supports both extended desktop (second workspace) and video mirroring (internal display duplicated on the external display) modes.
Then I'd consider...
