I received the cable on Thursday of last week. Duayn did a great job on cable assembly and packaging. I opted for a 12' cable as I haven't ruled out the trunk installation yet. After updating the EPIA BIOS for CRT+LCD, the panel powers on and I can see the BIOS splash screen and POST operations. Once the PC boots into GRUB, the colors are off. I experimented with all 16 LCD choices in the LCD type BIOS selection. From my understanding, this hex code sets the native resolution of the panel.

Note that I did have a loose LVDS cable but I reseated it. I may need to solder this connection as the cable was completely disconnected. LVDS is very fragile! I wonder if I can find a molded Hirose connector with wire stubs that I could just solder and heatshrink tube to the cable wires. I suppose I could also hot glue or epoxy the connector and wires to provide some strain relief, but I am concerned about electrical side effects (i.e. conductivity) of this approach.

I need to check the 262K vs. 16M color selection, but this looks like something else. I hope the panel controller voltage is sufficient. I was concerned about the resistivity of the 12' cable at 30 AWG dropping the voltage. Need to get the DMM and probe 3V pins. I had Duayn use 18 AWG for the inverter power pair (actually two sets due to current limitations of the smaller AWG), so inverter should be OK. The panel controller pulls much less.

Note the NEC 17" monitor as a reference. The flash caused a glare here but not for the NEC panel. With 10K pot turned to maximum (2.5V) the panel is nice and bright. If ERG datasheet is valid, I could upgrade to 950 cd/m2.

I need to get the panel mounted into the bezel and secure the cable on both ends so that the connector doesn't suffer any strain or stress. Then I can take this outside and snap some photos of direct sun. But first I need to debug this cable. What is going on here Sigh, the pitfalls of kitting my own display
