    Hello everyone,
    I'm trying to connect the UDOO to the monitor (LG flatron L192WS) by HDMI adapter, and I get the following message in the panel, OUT OF RANGE 67.5kHz / 60Hz.
    I tried with Android, Linaro and Lubuto, but the message is the same.
    if I connect it to TV Samsung 933HD works perfectly.

    can someone help me?

    thank you

    Re: Udoo and Monitor --> OUT of Range 67.5kHz/60Hz

    Hi, the problem is the monitor works at a different frequency than udoo, you can try to change the udoo frequency.
    You connect the udoo to pc with serial debug and insert the the string for linux or android with new fequenzy.
    i think that the screen works at 70 hz, because udoo work at 60hz.

    HDMI with Linux:
    setenv mmcargs setenv bootargs console=${console},${baudrate} root=${mmcroot} ${hdmi_patch} fbmem=24M video=mxcfb0:dev=hdmi,1920x1080M@70,bpp=32

    HDMI with Android:
    setenv bootargs console=ttymxc1,115200 init=/init video=mxcfb0:dev=hdmi,1920x1080M@70,if=RGB24,bpp=32 video=mxcfb1:eek:ff video=mxcfb2:eek:ff fbmem=28M vmalloc=400M androidboot.console=ttymxc1 androidboot.hardware=freescale mem=1024M

    After you insert boot to start the os.
    If doesn't work you change the value after the @.

    if the string works you can save the setting using the command saveenv.

    Thank extream96.
    I'll try tomorrow, but it is strange! because when I connect a Windows PC and go to Start, Control Panel, change resolution, advance settings, the frequency is 60hz.
    However, I'll do a bit of testing with frequency and different resolution.

    PS. is there a command that gives me back the current settings in order to put them after the tests?

    Yes, there is the command that gives the current setting,the command is printenv, but if you don't use saveenv, the udoo doesn't save the new setting and if you reboot the udoo, it uses the precedent setting.
    However you can find the command for the resolution in this page(there are the settings also for the displays, but you can find the setting for the hdmi):

    SOLVED, it didn't take the command because I didn't stop the boot :)

    YES, it was not a frequency problem. I have only changed the resolution.

    Thank you

    Hey, I am facing the same problem regarding connecting it with a output device. I am using HDMI to VGA converter to get the output on an old monitor.

    Can you please tell me which settings did you use to solve the out of range issue?
    i mean the resolution you used and the refresh rate used.
