[opensuse] xrandr info HDMI-1 disconnected
After an interesting read about the inner working of xrandr I started reading the manpage. Got the version of my xrandr and got further info about my system. And then I was lost in a swell of info and possibilities. My problem with monitors is following: I am using as my main monitor a Philips 196V3L, 18,5" 13766x768. For movies and such I would like to use my television set with a bigger screen via HDMI. The TV has one HDMI plug which is connected with a box from the TV provider. If I disconnect the tv from the tv box and plug it in on my motherboard I can use HDMI as my second monitor. That is not feasible for daily use. I found myself a HDMI cable with one HDMI connector and on the other end three colored (green, blue and red) video plugs. When I plug this cable into the HDMI plug of the motherboard and the three colored video plugs int the TV set I expected to receive a signal on the TV set. The television set is only showing the input "component" with these three plugs inserted. With xrandr I read HDMI-1 and -2 disconnected. Also DP1 and 2 are not connected. How can I force a connection with the HDMI cable and would that change anything? -- opensuse:tumbleweed:20170913 Qt: 5.9.1 KDE Frameworks: 5.37.0 kf5-config: 1.0 KDE Plasma: 5.10.5 plasmashell 5.10.5 Kernel: 4.13.1-1-default Linux User 183145 working on a Pentium IV . -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I suggest that even if you were to figure out an xrandr command that would cause the TV to be recognized you would not be pleased with the lowfi result. Component video[2] is analog video with limited mode support. Instead, abandon attempts to use that cable and get a 2X1 HDMI switch[1] so that only normal HDMI connections can be used on every end and xrandr and xorg will recognize the TV automatically.

Thanks Felix. Was already wondering if such a HBMI cable exist. Will see to it that I get that HDMI switch soonest. -- opensuse:tumbleweed:20170913 Qt: 5.9.1 KDE Frameworks: 5.37.0 kf5-config: 1.0 KDE Plasma: 5.10.5 plasmashell 5.10.5 Kernel: 4.13.1-1-default Linux User 183145 working on a Pentium IV . -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I've got a 3XT HDMI switch, which I use for just that purpose plus a couple of other connected HDMI devices. I run the HDMI output from my pc to the tv through that so the tv is recognised as a second monitor. It works very well. I'm running 42.3 with onboard Intel graphics but it also works on Linux Mint and earlier versions of openSUSE.. I can't give you a link to the model as I bought it a long time ago and looking at it it doesn't have the make or model number. It does have individual buttons for each of the connections which I believe is a desirable feature rather than the switch doing it automatically, not being an expert in these things I seem to recall that this is the best way of doing it. I seem to remember that I tried one with auto switching and it didn't work that well. You might want to researchsearch further into all this before buying a device.

Unless it actually does conversion from HDMI (digital) to component (analog) it probably is not going to work. There are cables that are just adapters between different connectors and are suitable only with special equipment. I doubt your TV actually accepts digital input on component connector.
When I plug this cable into the HDMI plug of the motherboard and the three colored video plugs int the TV set I expected to receive a signal on the TV set. The television set is only showing the input "component" with these three plugs inserted.
