    Could LVDS experts please have a look at this panel?

    Hi

    I'm trying to come up with a solution for heavy duty photo editing. Part of it should be a high resolution monitor with RGB-LED illumination.

    I found this panel from a Dell Precision M6400, Dell part number FR928
    http://cgi.ebay.ch/Dell-Precision-M6...3286.m63.l1177

    Can you have a look at the lower photo in the auction which shows the cables? Which ones are the signal cables and which ones are the cables for the illumination?

    Would this panel presumably work with the Kontron CRTtoLCD-6 controller?

    I've asked the guy of the auction similar questions. He said it won't work. But he didn't say why not.

    Thanks

    im not an expert, however i would say neither one of them, however i havent opened an led backlight monitor yet, my guess out of the 2 would be the smaller wire, however even LEDs would probably require a thicker wire with more current. and i doubt the controller you selected will work, based on pictures the cables dont mmatch the controler's outputs...

    For a Wuxga laptop screen you would need the Kontron CRTtoLCD7 Multimedia Board. But I don't know if they even make it anymore.

    A better choice is the Pixelworks PW338 controller. It is built to work with the 15.4" Wuxga Dell replacement Lcd panels.

    Which begs the question why you want to go with the 17" Lcd instead of the 15.4"

    Well, why not? There is this RGB-LED Dell panel as well, for the same price of 500 dollars:
    Dell Precision M4400 15.4" WUXGA RGB LED DISPLAY TR217

    Do you think the electrical interface is any different between the two? Will they work with the Pixelworks PW338?

    I'ts gotta be a RGB-LED Panel because they have a wide gamut that exceeds the AdobeRGB color space.

    I was just wondering why you would need the larger panel? Oh I see you're not using this in a car.

    Hmmm well back when I was helping test these controllers, the Pixelworks would work with a standard Dell replacement 15.4" or 17" Wuxga Lcd. But as far as an RGB lcd, I am not sure.

    Also you would need a power supply to drive the leds. I know for some of the led backlit lcd's I've tested they needed between 25v and 35v power adapters at around 3A.

    Just some background. I'm trying to build two setups.

    1) My photo mentor buddy needs a semi portable solution do work in the hotel room. He wants a Core i7 compact mATX based CPU with initially 12 GB of RAM and sometime later upgradable to 24 GB as soon as 4 GB DDR3 DIMMs are available and semi-reasonably priced. Plus a compact high quality monitor. Notebooks can be had with a max. of 16 GB but this configuration costs an arm and a leg.

    2) I upgrading my CarPC to initially 8 GB, later upgradable to 16 GB. The WUXGA monitor would not be installed in the cockpit and not in use while driving. I would unpack it when it's time to do photo editing. I think I will work in the driver's seat and attach the monitor to the steering wheel. I can back up the seat to do that. I need an all-12V solution.

    We need the big memory for panoramic photo stitching.

    I've inquired with Pixelwork about these Dell displays.
