What about using IGP ports on Skylake/Kaby lake can you use a DVI to HDMI adapter and overdrive it like Nvidia pixel hack?
Also what about replacing the board on the monitors with one that supports more ports? Anything like that? these active adapters are bank 80$ a piece, also it is very flaky when I start a Netflix video it goes all messed up sometimes until I unplug it and plug it back in basically some strange compatibility issues.
I have 3 Korean monitors, one x-star, qnix and a Shimian, and I really don't want to replace them especially since everything out there isn't even as good as these!! Is there a better adapter or any other way of hacking the board to include DP by replacing the IC board on the monitor?
