[beagleboard] Re: What limits Beagle Board Black HDMI resolution

People, read your docs… According to the latest System Reference Manual, BBB added support for 1920x1080@24Hz resolution: https://github.com/CircuitCo/BeagleBone-Black/tree/master/BBB_SRM.pdf

[beagleboard] Re: What limits Beagle Board Black HDMI resolution

Per above, it seemed that 1920x1080 was possible in the 50-60Hz range without audio. Has the community been able to figure out a way to get that to work? Thanks! On Friday, November 1, 2013 3:24:35 AM UTC-4, draw...@gmail.com wrote: > > People, read your docs… According to the latest System Ref

We managed to get 1080p images running on the BeagleBone Black over HDMI. It runs at 50Hz, and won't work with every monitor, but it's working on our 27" at the moment. http://meural.com/hardware/HDMI_1080P On Friday, July 4, 2014 7:07:01 PM UTC-4, Chip Estrada wrote: > > Sound like you need a

Does that mean I can use a resolution of 1280 *768 * 60Hz with a 720p Video on the BBB On Wednesday, May 22, 2013 at 10:46:02 PM UTC+1, David Anders wrote: > > the “maximum” resolution is directly related to maximum pixel clock of > 85MHz with audio support. it supports any resolution as long as

Sound like you need a Raspberry Pi. They have amazing video and the GPU kick butt over the BB capabilities. On Wednesday, May 8, 2013 3:05:24 AM UTC-7, ric...@aardvark.com.au wrote: > > The Beagle Board Black system reference manual rev A5.2 says (in the HDMI > section): > > Currently the fol

1920x1080@24HZ is the best it can do. Gerald On Sat, Nov 2, 2013 at 1:19 PM, wrote: > Per above, it seemed that 1920x1080 was possible in the 50-60Hz range > without audio. Has the community been able to figure out a way to get that > to work? > Thanks! > > > On Friday, November 1, 2013 3:24

Re: [beagleboard] Re: What limits Beagle Board Black HDMI resolution

Great, now how does one specify a particular resolution and audio option upon startup? On Saturday, November 2, 2013 4:32:32 PM UTC-4, Gerald wrote: > > 1920x1080@24HZ is the best it can do. > > Gerald > > > > On Sat, Nov 2, 2013 at 1:19 PM, > wrote: > >> Per above, it seemed that 1920x1080 was p

Re: [beagleboard] Re: What limits Beagle Board Black HDMI resolution

I'd like to refine my question to you Gerald... How can I get 24-bit color with the BBB via either HDMI or LCD (assuming the LCD I wire up is a 24/32-bit color panel)? I thought the TI spec indicated the BBB could drive true-color but all I can manage to get out of the BBB is 16-bit color rega

Re: [beagleboard] Re: What limits Beagle Board Black HDMI resolution

All 24 bits are available on the expansion headers. I cannot speak for 4D systems as to how their board is designed and if they support 24b mode or not. HDMI only has 16 bits connected, so you cannot get 24b color on it. Gerald On Tue, Nov 12, 2013 at 8:37 AM, wrote: > I'd like to refine my

Re: [beagleboard] Re: What limits Beagle Board Black HDMI resolution

Thanks Gerald, I will have to confirm this by wiring up another LCD panel to the expansion headers. It's unfortunate to learn that there is a 16-bit color limitation via HDMI output. On the Raspberry Pi I can issue the "fbset -depth 24" bash command and the HDMI output switches to 24-bit colo

Re: [beagleboard] Re: What limits Beagle Board Black HDMI resolution

We did this for a reason. Our focus was expansion and due to the pin muxing, the extra 8 bits would wipe out a lot of functionality. Se we decided to make those easily accessible when connected to a monitor. Gerald On Tue, Nov 12, 2013 at 10:27 AM, wrote: > Thanks Gerald, > > I will have to co

Re: [beagleboard] Re: What limits Beagle Board Black HDMI resolution

Higher color output through the HDMI connector uses up pins? On Tuesday, November 12, 2013 12:14:46 PM UTC-5, Gerald wrote: > > We did this for a reason. Our focus was expansion and due to the pin > muxing, the extra 8 bits would wipe out a lot of functionality. Se we > decided to make those eas

Re: [beagleboard] Re: What limits Beagle Board Black HDMI resolution

Yes. There are a certain amount of pins on the expansion headers. Each pin has up to 8 functions per pin. For each pin that is set to the HDMI function, the other 7 functions are no longer available to the expansion header when the HDMI is in use. Some of these functions are some of the more popul

Re: [beagleboard] Re: What limits Beagle Board Black HDMI resolution

Yes, looking at the board schematic, in order to use LCD_DATA16 - 23 (missing 8 bits) you would have to give up 6 GPIO's and 2 PWM's. On Tue, Nov 12, 2013 at 3:03 PM, wrote: > Higher color output through the HDMI connector uses up pins? > > > On Tuesday, November 12, 2013 12:14:46 PM UTC-5, Ger

You cannot do 60Hz. The processor will not support 60Hz. http://www.elinux.org/Beagleboard:BeagleBoneBlack#BeagleBone_Black_Features Gerald On Mon, Feb 1, 2016 at 9:51 AM, wrote: > > > Den onsdag 22 maj 2013 kl. 23:51:06 UTC+2 skrev Robert P. J. Day: >> >> > (1920 x 1080 x 60Hz = 124416000 = 1
