[beagleboard] Beaglebone Black not posting to display
Hello BBB community: Since I received my Beaglebone black, I have been wrestling to get it to work with any display whatsoever (other than the ones thai *do* work in Best Buy) I have sent this board into the shop and the hardware is fine, but I just can't get it to work with any of the displays I've connected it to, with one 7" display in particular. What do I need to do to get this thing to work? NOTES: -When connecting to most displays, the 'Bone keeps the display awake, but it won't actually display anything. - my 27" Samsung display worked at first, but now it doesn't, and only occasionally flashes the desktop for 1-2 frames. -EDID Information of my fav. display from serial console: parse-edid: parse-edid version 2.0.0 parse-edid: EDID checksum passed. # EDID version 1 revision 3 Section "Monitor" # Block type: 2:0 3:fc Identifier "HDMI" VendorName "IVM" ModelName "HDMI" # Block type: 2:0 3:fc # Block type: 2:0 3:fd HorizSync 29-82 VertRefresh 55-76 # Max dot clock (video bandwidth) 140 MHz # Block type: 2:0 3:ff # DPMS capabilities: Active off:yes Suspend:yes Standby:yes Mode"1280x800" # vfreq 59.810Hz, hfreq 49.702kHz DotClock83.50 HTimings1280 1352 1480 1680 VTimings800 803 809 831 Flags "+HSync" "-VSync" EndMode # Block type: 2:0 3:fc # Block type: 2:0 3:fd # Block type: 2:0 3:ff EndSection I have reached the end of my rope in this regard and really, *really *want to get to the fun stuff! -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

Thank you for your quick response, Robert! Unfortunately, that did not work. The output for *cat /etc/dogtag* is BeagleBoard.org BeagleBone Debian Image 2014-05-14 Thanks! -Tyler On Sunday, November 30, 2014 2:40:09 PM UTC-9, RobertCNelson wrote: Force override the edid detection by modifying: > > /boot/uEnv.txt > > add: > > cmdline=video=HDMI-A-1:1280x800@60e > > If that file doesn't exist, let me know the output of: > > cat /etc/dogtag > > Regards, > > -- > Robert Nelson > http://www.rcn-ee.com/ > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

Re: [beagleboard] Beaglebone Black not posting to display
Oddly enough, forcing that resolution worked for my 1080p monitor, but not the 1024X768 one :/ Any ideas on how to get the 1024 one working? It's a $60 7-incher I bought just got the board, and it'd be a shame if it sat somewhere collecting dust!

[beagleboard] No display output; detects the monitor
Hi there! I have been having issues with getting my BeagleBone to communicate correctly with my displays. Last night I installed Angstrom (after wrestling with the Debian OS for several days) and was surprised to see that the 'Bone sees and gathers info from the display (stated the monitor was a Visio) through the pre- installed display utility, but the monitor itself gets no signal. I am able to access the GUI through a VNC connection to my Macintosh. I have been able to get the Beagle to work with only one display, a $450 monitor we used at Best Buy to test the micro-HDMI to HDMI converter I am currently using. This tells me it isn't a hardware failure, thank goodness. Any thoughts on what to do? Mind you, I have full access to the GUI and internal console, so any route to success is feasible. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
