  • Contrast Questions

    I hope a simple question concerning the contract command please.
    I'm running a gen4-uLCD-70D display and my question is what does the displays contrast default to in the absence of a contrast instruction?
    I'm asking because I notice that if I command contrast=15, with both the program and the GTX tool, the display initially draws over 1 amp before re-booting. If I command a maximum of 12 or no instruction at all, the display is fine.
    Many thanks......

    Hi,

    The default contrast setting is 12

    When the Contrast is increased then the display will draw more current and exceed the current that the USB can provide and as you notice reboot.

    I hope this helps

    Best regards

    Paul
