Pi-View HDMI VGA converter problem

Former Member

Hello all,

Please bear with me as I am new to this. I have run my RPi on my home TV using a HDMI to HDMI cable.

However for working in school, I have bought the Pi-View HDMI-VGA converter and when I connect this to a 50/60HZ monitor I get the screen message;

"Attention signal frequency is out of range

H: 67.5kHz V: 60.5 kHz

Please change signal timing"

 

The Pi is powered via USB (phone lead) through a second PC and I have a steady green LED.

If I power the Pi via a powered USB hub, then I see an intermittent messgae;

"Attention no signal

Please check input signal or connection"

 

Can anyone please advise where I may be going wrong?

Thanks in advance.

  • I bought a really nice Cirago HDMI-VGA converter from Microcenter for about US$32.  http://www.microcenter.com/product/431089/HDMI_to_VGA_Adapter_with_Audio

     

     

    It worked fine with the NOOBS environment.  When I booted up Raspbian, it worked with one of my monitors (an old Dell).  However, with my other used (AOpen f2705-12s) monitors I got the message "Out of range" and nothing else.  The specs for this monitor (which I found online) give a resolution of 1280x1024 at 60 Hz.  So, I looked that up on the list of EDID settings:

     

     

    HDMI group to 2 (DMT)

    and

    HDMI mode to 35

     

     

    Those settings match 1280x1024 at 60 Hz.

     

     

    Also set HDMI drive = 2, although I have not yet tried any audio through this adapter.

     

     

    When I rebooted Raspbian with those settings, I got a momentary flash of "Out of range" and then a black screen and then the monitor worked correctly, first scrolling out all the boot message and then booting and displaying Raspbian's desktop environment.

     

     

    I recommend not giving up on the HDMI-VGA route, because (at least where I am) there are a lot of old cast-off VGA monitors around, and that makes for a more reasonable development rig than hooking up to a hi-def TV.  (I certainly agree with the Raspberry architects' selection of HDMI, of course.)
