Thx, than the explanations and the way offered by Peter are correct and MichaRs comments targets to a other context. But the main questions about the new PCB you haven't answered - ETA and location?
ETA= When it's done

As a little Christmas present I want to show you what I've been working on: the LVDS4PI EVO --> an evolution step of the LVDS4PI.

The EVO has a simpler board layout, simpler DC/DC circuitry and a more advanced LVDS transmitter, now supporting JEIDA and VESA from a single board and with dual-channel LVDS output!

looks neat! up to what resolution does it support?

I've got a screen from my now defunct Vaio (15" 2K screen) and been looking for LVDS for that.....
"Don't come to me with 'issues' for I don't know how to deal with those
Come to me with 'problems' and I'll help you find solutions"

Some people be like:
"Help me! Am drowning! But dont you dare touch me nor come near me!"

max resolution supported by the LVDS transmitter is QXGA = 2048×1536pixels.

I've only tested up to FHD (1920x1080) so far.
