a123xxsp Posted September 14, 2016 Posted September 14, 2016 Hi, my configuration is: Asus 5V 2A power adapter with usb to 1,7mm cable, Kingston microsd 16GB class 10 with Jessie desktop I can SSH the OPi so I can use H3disp output to HDMI (TV) works fine output to HDMI -> DVI to PC monitor works fine is it possible to use HDMI adapter to DVI, DVI to VGA and get the image to a PC monitor via VGA? i tried it using -d switch but nothing shown on monitor, do I need any special command? or this is not possible at all? please advice, Thanks
zador.blood.stained Posted September 14, 2016 Posted September 14, 2016 is it possible to use HDMI adapter to DVI, DVI to VGA and get the image to a PC monitor via VGA? No. HDMI signal is digital, DVI can be either digital only (DVI-D) or digital+analog (DVI-I) and VGA is analog only. All passive HDMI to DVI adapters provide only digital signal (as far as I know), so unless you buy active DVI-D to VGA converter like this or this you won't get any signal on VGA monitor, but at that point you may want to buy HDMI to VGA converter instead.
rodolfo Posted September 14, 2016 Posted September 14, 2016 HDMI to VGA converter is needed. Get one with optional audio output for a few bucks on ebay/ALI.
a123xxsp Posted September 14, 2016 Author Posted September 14, 2016 Thanks guys! I will buy the converter BUT I wonder why simple DVI -> VGA adapter work for use it to get output from an ASUS Eee to my VGA monitor? like this one : https://goo.gl/g2dAqA by the way I suppose this https://goo.gl/pWJlH1 won't work it says : a signal conversion box is required but this should right? https://goo.gl/MXKHg4 it says Built-in converter chip, support hot plugging I Don't need the sound
zador.blood.stained Posted September 14, 2016 Posted September 14, 2016 I will buy the converter BUT I wonder why simple DVI -> VGA adapter work? (I use it to get output from an ASUS Eee to my VGA monitor) Because your laptop has DVI-I output, which has analog signal in addition to digital. If it had DVI-D output, you would not be able to insert your DVI to VGA adapter: https://en.wikipedia.org/wiki/Digital_Visual_Interface#/media/File:DVI_Connector_Types.svg 1
