Right, the question would be if you can get it into that mode and override it from its hard-preset 120hz 1080p that it sends for 4k 30hz without the source code (I browsed the disassembly for a while but couldn't get it to push past 120hz when in 4k mode, though it's not an easy task to find.)...

As has been mentioned many moons ago in this thread, to get native 4k resolution the input board feeds 120hz 1080p to do 4k 30hz (sending 4 1080p frames per frame.) I think this adds a lot of the input lag. It also forces it to run at 30hz 4k, and it simply cannot without a lot more modwork...

The former is the tcon board and the latter is the input board it looks like. You would need both to ultimately get a displayport signal through to the tcon through to the panel, assuming it also includes the cables needed to connect the three together.

I did a diff of this 20140707 firmware with the original se50uy04_20130528 firmware, and they are identical when uncompressed (the compression of course being the cause for different file sizes.)

Pretty easy if you are used to disassembling monitors/tvs. Just want to be careful with the ribbon cables and prying the bezel off. Work the edges to pry off the front bezel of the u28d590, then pull the monitor out a bit to unplug the led and panel cables behind it before pulling the panel...

I have an SE39UY04 and U28D590 lying around so I took the board from the u28d590 and plugged it into the se39uy04. I got 60hz 4k just fine, only problem is inverted colors (though there are various software solutions it seems to solve this, not sure if there's a different way to connect to fix...

I unpacked the 50" firmware, and disassembled the main DvdPlayer process (a mipsel instruction set). I found where it turns on the scaler at I think 549df0 or somewhere (I don't have the laptop I used on hand, but if you look for a load immediate 3840 near a 2160 in the disassembly, it is the...
