What about the D945GSEJT LVDS connector for LCD Panel? (yes, those LCD panels used in notebooks)
Does anybody know which LCD Panel, LCD inverter and LCD/inverter cables would work with D945GSEJT?
I found a "White Paper" about Intel LVDS: http://www.intel.com/support/motherb.../CS-030675.htm
I am planning to use a 15" LCD Panel.
TinyQ can you please explain how you did activate the LVDS port from the mother board because it's blocked by default and can't be activated. Or perhaps you can directly give the bios you are actually using, that will be really great. I took this motherboard for the LVDS port, but it's only after that i realize that intel don't want provide any help about it. so i am stuck with this board
There are various reasons why Intel has this feature disabled. The mail one is that it can violate the ECC cert they obtained for the board. For them to legally sell the board here in the US they have to comply with the ECC rating. There is a DOS file that has to be run to enable the LVDS. It should be on Intels site under the product info.
What cables and panels work is another matter. Just about any panel will work, but the connector on the panel dictates the type of cable used. We recently had to have a cable made for a panel that uses an IPEX connector. A real mother since it uses micro coax.
I need to connect this board to a
LVDS output as an asset?
LCD only works in WinXP after the launch of video drivers.
driver I generated with the help of Intel Embedded Graphics Drivers are downloaded from Intel website.

using the Intel Embedded Graphics Drivers may create VBIOS, but I do not know how to flash in the motherboard
The CED also creates a VGA.bin file, which is the Option ROM which must
be merged with your system firmware. Contact your firmware provider for
instructions on merging option ROMs with the system firmware.
Can you help us with some more details on what you went through to get the LVDS running?
I have the Intel Embeded Graphics toolkit.
What I'm wondering is if you enabled either of the other video outputs (VGA or DVI-D), and if you specified timings for your LCD panel or if it was just EDID compatible and you just used that.
I'm trying to get a B089AW01 V1 panel working. They're usually used in netbooks and are cheaply available on auction sites and such...
The datasheet lists the timings and all, but the panel is EDID compatible, so I'm thinking that I can just use that rather than putting them in manually...
If you can help me generate the proper driver, I might be able to help with figuring out the flashing of the VBIOS...
The problem with the panel you have is that it uses an APEX connector. Apex uses micro coax not traditional stranded wire. You are going to have a hell of a time getting it to work. If you get the cable worked out the proper settings for an AUO panel would be 5v for the backlight and 3.3 for the panel. Make sure you dont put 12v to the backlights or you will somke them. Been there done that.
Well, I've got the original wiring assembly that went from the LCD to the motherboard of the net-book, so I guess I'll start with taking that apart carefully on the Notebook side. Sounds like my lighted magnifier lamp is going to come in handy...
Worst case, I'll just desolder the connector from the back of the LCD and wire it directly. Tedious, but doable.
Any idea where to get the connector that fits the d945GSEJT board? I haven't gone through the process of sourcing that. Not sure if it's something that Mouser or Digi-Key carry or not...
I can tell you that it is possible to make a cable that goes from an IPEX connector to the JT inverter and LVDS connectors. I can also tell you that it took 2 engineers going back and fourth for a week or so to figure out the pin out for this cable, and one of them works for IPEX. They are also expensive to make, as in samples of it were over $60, but I dont know how much it would cost you to make one. Production pricing was better but still expensive. If I can find the email with the pin out I will post it here.
I only know all of this because we provided this board and panel to a customer for a project.
You may want to consider picking another panel that doesnt have an IPEX connector on it.
