    I think somewhere back on the first few pages of this thread there is a "direct sunlight" pic of this so called transflective screen with the brightness set to "0". Seems to me that as with most monitors, the brightness is simply an adjustment of the image and not a lumen adjustment of the backlight lamp. I discovered the same thing with my MoCoSo transflective screen that was supposed to have 5 stage backlighting. Adjusting the "brightness" via the OSD did nothing to adjust the lamp output. Makes it difficult to determine how much of the image is being produced by the backlight vs the transflective nature of the display.

    Yeah, somebody will have to test and report back if this Samsung has a separate adjustment for the backlight. On the Xenarc 700TSV that I have (terrible screen), I do have backlight (0-99) and brightness separated. Brightness can really wash up the whole image, but the backlighting doesn't, it *appears* to be actually controlling light output.

    Interesting. Maybe I need to poke around in the menu again, but I didn't see the backlight adjustment on mine. I'll get photos up as soon as it is installed. Probably in a couple more years

    I bought the screen last year to replace the Xenarc which was horrible. With the massive sunroof, the touch screen was like holding a mirror and looking directly at the sun with it.


    I was in a boat store the other day and the fish finder/nagivation systems had incredibly bright displays on them. Now why can't we have that in our cars?

    EDIT: Just took another look at mine, there are 5 stages of brightness accessible by pressing the "up" arrow on the remote, but it is just an image processing thing. The backlights remain the same intensity (I have the screen out of the enclosure.)

    Yes, there are two seperate settings in the menu, Brightness1 is the backlight (can only be set to 0/25/50/75/100%) and Brightness2 is the actual LCD (can be set 1-100).

    I've pulled the PC for maintenance last night (getting a new case, need to squash the electrical noise I suspect is from the M4-atx, and add some relays). But I need to pull the LCD panel and figure out the washed-out-blue issue I have, so will try that tonight. It'll be a few days before I can take a sunlight-in-the-car picture again.

    sebberry- Cool that you have the same car. Today I think I decided to order the replacement auto-AC/Dual DIN unit so I can put the screen lower in the car, and get my cubby back ( $400! ). I put it up there for a trial, and I don't like it too much. Too bright at night (I can't dim it yet), I have to lean away from my seat to reach the touch screen (or to read it sometimes) and it seems a waste to have the stock radio in the car once I get everything working on the PC.

    I was even kicking around the idea of moving the AC controls to the glove box (as a backup) and going Fusion Brain all over them so I can control them from the touch-screen (13 relays would do it). Then I could do a 10" touch screen too, at a higher resolution.

    I pulled my LCD from the car. The brightness for my pictures was set to 80, as was the contrast. The other options on the menu are NOSYNCOFF, Hposition, Vposition, and AUTO. When I cranked up the brightness and contrast, the screen did appear brighter (in my office, at night). I'll take another set of pictures with it when I can get my gear back in the car.

    The bad news is that I still have an issue with washed out blue. This is with no VGA plugged in, and it is still "smeared". When booted to windows it is less noticeable, but still there.

    Is that the newer version with the updated firmware that lets you hide the OSD? If so, were you able to do that?

    No, my unit is the older VGA input version, not the newer HDMI version with the other modifications available too.

    OK for ths outside size.

    And about the touch area. Does it match with the viex area of the samsung panel?
    I mean, is it possible to touch in the four extrem corners of the screen?

    I asked that because some I already bought a package TFT + touche screen a day to another seller and I wasn't able to click the red cross to close windows when navigating under Windows OS.
    Thank you for reply.

    Yes, you can touch the far corners of the LCD and it will register a touch command.
    Since the Capacitive touch panel is slightly larger than the Samsung LCD, the touch screen active area exceeds the LCD's viewable area.
