Now why the hell are they only 262k colours ? What kind of crazyness is that?
Notice they are both LVDS 2 channel interface. ?
This only supports uxga but will it work with a uxga samsung lvds screen?

Does this mean we can run any modern laptop screen with an lvds motherboard? Dont tell me its that easy...
I've wondered the same thing Drac. Some Mini ITX Motherboards are including LVDS connections on them now, and I've wondered if it was really that simple. Just doesn't seem like it could be.
Hope someone knows...
Hope someone knows...
I'ts not that easy, i checked all of those mini-itx boards that have that connection and they can't handle those res, and laptops hinder the amount of things you can have on your pc, basically, it would suck, laptops are not good for any home pc application except maybe a really crappy htpc, but barely even that, i sent an email to some ppl about something that might work ill write back when i get a reply from them!
Can the mini itx boards can handle uxga? What do you mean laptops hinder the amount of things you can have on your pc? Do you mean the laptop lcd screen?
A itx motherboard has nothing to do with laptop nor does it know its hooked up to a laptop screen.
Or are you talking about laptop controllers?
Guys,
The video chipset that many of these mini motherboards are using is an Intel extreme 2 and the chip can do up to QXGA which requires 2 channel LDVS interface. The only question is whether or not the rest of the LDVS interface on the motherboard supports the higher resolutions.
The reality is that this chipset is not the best for gaming but it would proably be adequate for a HTPC and DVD playback and most games except the newest heavy resource games.
Check this link for more info:

It looks like the LVDS tranmitter they are using limits the resolution of the graphics to 1600 x 1200 but this is still high resolution.

So in this link of the photo which of the connectors is the LVDS port? And will all lvds screens work? I agree uxga is good enough for me. I asked some laptop parts suppliers in the area for uxga lvds screens and they quoted me $600 usd so I want to make sure the lvds connector it has works. What does an lvds connector on a laptop screen look like?
Is the pink port connector the LVDS 40 pin connection interface in the picture?
All the laptop screens I have seen so far on ebay have nothing like this. All I saw was a small connector about 3/4 inch.
This pink connector looks about the size of parrallel connector or 2 inches wide.
Also this MB has only 1 IDE slot so that means you need to hook a 66mhz bus speed dvd to a 133 mhz hard disk slowing the hard disk to 66mhz right?

Guys,
I have been doing a little research and I am coming to the conclusion that not all LVDS setups use the same connectors. There are two or three common types of connectors and one looks like an IDE type of connector. One of the other popular connectors is called a FTC or a FPC I can't remember. In some situations it may be necessary to have a cable made with one type of connector at each end and there are companies out there that do it.
I think the best thing is to just have the specs for both the output of the LVDS and the input on the LCD panel and then if necessary have a special cable made.

dracul said:
If you connect a dvd drive with an ata 66 interface to an ide slot the maximum transfer rate will be 66 mb/s
If you connect a hard drive with an ata 66 or faster interface it will also run on ata 66.
Your hard drive will probably never reach 66 mb/s unless you have a very fast one.
You will probably not notice the difference betwean a hard drive connected to ata 66 and a hard drive connected to ata 100.
Even ata 33 is more than enough for a htpc.
There is a pci slot on the motherboard, so if you want more speed or just want to connect more than two drives just put in an extra ide controller.
So your are saying pick any decent lvds motherboard and lvds screen and I can count on making it work?
Worse case I need a special cable made?
Dracul,
I think you hit the nail on the head. As long as the motherboard can drive the native resolution of the LCD and they are both LVDS you should eventually get them to work. Though you may have to have a special cable made in some circumstances. It also might be necessary to program the video bios in some situations but I would opt for a motherboard that has a VGA in addition to the LVDS because it makes it easier to get everything up and running as you can monitor on an old CRT computer monitor.
I only wish that someone would make one of these small motherboards with a high end LVDS transmitter on it so it could utilize the maximum resolution of the grphics chip. Perhaps soon as high resolution LCD's become more common.
Anyway, even at 1600 x 1200 you are past the resolution of HDTV. The biggest limiting factor right now may be that we don't have a high enough quality lens for our larger LCD's.

I think this motherboard is ideal for this.
http://www.commell.com.tw/Product/SBC/LV-671.HTM
Pentium based, 5.1 dig audio,ddr ram,standard ide etc
supports true 24 bit 1600*1200 lvds
also simultaneously will run standard vga out so you can have a monitor too
looks nice, they have a whole line of good looking boards
I'd like to match one of these with an SGI 17" LCD and see what happens

Doh sorry didn't noticed you posted that board hezz, sorry to double post the info.
I like the p4 mini itx board they have too, it looks yummy

Faithblinded,
I think this is our best bet for now until someone makes some high end AGP LVDS controllers more available. I'm not sure what kind of data interface the SGI 17 inch has. I thought that it was some kind of proprietry design that uses a special card for that monitor. Anyway, it would be nice to find out. It might be a good idea to get a cheap small raw LCD to try out with the motherboard just for a go. Some of the older LCD's can be had on the cheap but might be good to experiment with.

Dracul,
This is interesting to read but it certainly doesn't make the LVDS compatability issues any more clear.
Generic LVDS
Low-Voltage Differential Signaling is a generic interface standard for high- speed data transmission. The ANSI/TIA/EIA-644-1995 standard specifies the physical layer as an electronic interface. This standard defines driver and receiver electrical characteristics only. It does not define protocol, interconnect, or connector details because these details are application specific. The LVDS Standard's Working Group chose to define only the electrical characteristics to ensure that LVDS becomes a multi-purpose inter- face standard. Therefore, each application that uses LVDS should also reference the appropriate protocol and interconnect standard.
This statement is from a website a couple of years old and certain standardizations may be occuring in the computer field due to the popularity of desktop LCD screens. The fact is that perhaps I was too optimistic about how all LVDS interfaces can work. But I would think that most chip makers would want their LVDS drivers to be as compatable as possible so that many LCD panel options could be used. Just because the basic LVDS standard does not describe the complete system doesn't mean that many computer system makers have not undertaken agreed upon practices for most devices. I guess in the end we will have to experiment and sacrifice some cash in the persuit of high rez.
It is important to realize that LVDS technology is used in many other applications besides LCD panel data transmission and that each discipline may have common types of wiring and connectors that differ from the usual LCD panel connectors. What I think is the most important thing to know is that whether a controllers LVDS transmitter is compatible with the LVDS reciever on the receiving device. And whether or not the signaling methods are compatible. This needs to be explored further by me.
