    I am aware that you always need a higher voltage cap, or the same at the very least. But what's the advantage to using a .33 uf over a 1500 uf cap or 47 uf instead of .33 uf?

    I think it has something to do with the voltage drop and current loss. Those specs are provided by the manufacturer in the datasheet. SNO

    I bought one of these a while back, probably 12 months or more ago, and noticed they now have "auto-switching" feature for reverse camera. I haven't tried yet, but will mine automatically switch from HDMI to VGA input for a reverse cam? If not, is there a firmware update available, or any modification I can do?

    I recently bought one of these and have a few notes/problems:

    A) Connecting the "Audio In" connector fried one of the ICs on the display board (CS6---, located between the "Audio IN" and "To Speaker" connectors on the ebay image). Luckily the rest of the display functions and disabling HDMI audio appears to stop usage of the dead IC. There's no instructions as to how to connect the audio header. Confusingly, the Audio header cable has a USB header 8pin block, not the FPAUDIO 8pin block (the blank is in a different spot). Under the assumption it operated as a USB device, I plugged it into a header and it cooked. Strangely, the screen powered up as well without 12V supplied! Only 5V from the USB header was supplied, so I can only assume the 5V was flowing from the motherboard header and reaching the screen (via the audio connector? wtf?)
    I'm currently debating whether to order a new board. But even then, what's to say connecting the audio header wouldn't kill it again? I'm feeling lucky enough it didn't kill my ITX motherboard. Has anyone actually connected this and got it functioning? Pics would be nice.

    B) The left-side button board requires at least 3 screws. The center of the PCB flexes, such that the buttons in the middle are UNUSABLE and the force required on the buttons is overcome by the PCB flexing. I'm currently trying to find a way around this.

    C) The touch software works fine in Windows 8. But I can't swipe from the edges. I may need to tweak the edge detection settings.

    D) The 12V screen input works fine of the 12V Molex supply on my PicoPSU. I just cut and soldered the cable to one of many PCIE->Molex splitter cables I have lying around. Side-effect being the screen is only powered when the PC is, but that's no biggie (I don't intend on using the screen without the PC on).

    The reverse only switches to avi2 so you have to input composite video from an RCA jack.


    There was an issue posted many pages ago where they warned that you must connect both L and R speakers on the HDMI board, but connecting only 1 channel will cause the small audio chip to burn up.

    I searched the thread for info on the audio connector but I literally only received the screen a few days ago and haven't been able to go through the entire thread

    If you have an HDMI screen and you have both MHL and USB outputs from your phone you can drive the screen from your phone and use the USB port to connect to the USB touch screen and it would work like a mouse. I have actually hooked a mouse to my SG III before as a test as well as a keyboard. Haven't gotten the MHL port working with it though. There are Samsung branded docks that will allow me to have an HDMI and USB ports so I do know they are out there.

    Ahh, sorry, I meant switch from HDMI to RCA, not VGA
