    Can HDMI switcher damage devices?

    Hi friends.
    I purchased HDMI switcher so I could use both PC over one monitor.
    But I'm anxious to use it.
    Are these stuff safe to use?
    I'm affraid of short circuit over to monitor or even graphics card.
    Could not find who made this one,seems unknown.

      Re: Can HDMI switcher damage devices?

      It is made by China Inc. - there are many many many vendors and manufacturers of these devices. Some will have a focus on such a product while others will build a batch of them for a few weeks and move onto something else that is the latest craze / hype.

      Any poorly designed product can cause damage but usually the manufacturer will test each widget before packaging. That is common. How long the product will function is another story.

      Being an owner (and a design engineer) of a similar product - found that sometimes the video source is not detected for our multiple feeds. At that point, once in a while, have to unplug and plug back the video source while it is live. Then the switch 'auto switches' correctly. A minor fault and may have to do with the circuit they have applied or the HDMI IC used. Otherwise, the product is working fine.

      You should be fine to use yours but suggest to use gentle force to insert the HDMI cables and then apply power after they are seated. Sometimes the port will have ESD protection diodes to suppress static pulse that cause such damage. Avoid carpets (in general) and discharge your body by touching a metal ground before using any electronic equipment.

          Avoid hot swapping HDMI if you can.

              What you mean "hot swapping"?

              I don't know what the hell I purchased this device.
              Spent 10 euros for maybe crappy device which could damage my PC who costed me back in 2020, 2k euros...
              Maybe I do can try on 2 older PC.
              It is to that I do need them urgently.

                  What it sounds like, plugging in HDMI cables when they are hot, as in power going through it.
                  Lots of people plug them in hot and lots of people get away with it, right up to the point they don't.

                      Marantz SR4003 AVR HDMI board issue, seeking for help
                      by aliougm
                      I have problem with my AVR(Marantz SR4003) HDMI board issue. I connect to my TV but screen color distorted,see attached picture.

                      Connection as below:
                      Set-top box HDMI output >AVR 3 HDMI input/one HDMI output>HDTV HDMI port
                      If I bypassed AVR then HDTV screen color be good.

                      I take out HDMI board from AVR and check services manual the schematic shown the HDMI signals path:
                      3 HDMI input port > SIL9185 chip(HDMI switch) > SIL9033 chip(HDMI receiver) > SIL9030 chip(HDMI transmitter) > HDMI output port

                      HDMI over CAT5 with a HDMI switcher for more than one computer being monitored proof
                      by sam_sam_sam
                      I recently got a new shed that it my battery testing work bench beside this it also be electronic work bench as well and general work bench area as well

                      I want to have a way to monitor more than one computer that is doing battery testing on the fly so I can switch between monitors and be able to see the results in real time

                      I a chief engineer where I work gave me the information and idea to use a CAT5 repeater which would be the simplest way to do this

                      They use a different method to transmit the data to tv monitors around the facility but that system requires...

                      Certain DisplayPort-HDMI cables can disable HDMI CEC communication
                      by japlytic
                      With a setup including a TV and AV receiver where HDMI Consumer Electronics Control (CEC) and Audio Return Channel (ARC) functions were working, these two functions stopped working after changing some connections (not the one between the AV receiver and TV), so I believed it was a corrupt setting in the AV receiver or TV, but when I disconnected a passive DisplayPort-HDMI cable (which a Multimode DisplayPort connector supports HDMI with a low cost passive cable or adaptor) connected to a home theatre PC, HDMI CEC and ARC functionality was restored.
                      An examination of the HDMI CEC wiring...

                      Toshiba 50UL2063DB randomly rebooting with HDMI-CEC and/or HDMI-ARC enabled
                      by spleenharvester
                      I have this TV hooked up to only an AppleTV 4K and a Creative soundbar. Originally HDMI-CEC and HDMI-ARC wouldn't work at all, I replaced all the HDMI cables with decent UGREEN cables meeting the latest standards, now it all works perfectly but once or twice a day the TV itself reboots while watching a program, the AppleTV keeps running. I haven't fully pinned down whether it is ARC or CEC causing it yet. All are running latest firmware.

                      I assume it is just HDMI-CEC being buggy as usual on a shitty Vestel machine, but can anyone think of anything I can try before disabling it?

                      LG LCD TV picture comes on intermittenly using hdmi port.The sound is on permantly.The hdmi ports looks fine and soldered in securely.The 3.4v coming to the main board is not present(not sure if will affect the hdmi port or where that voltage goes.)The hdmi cable is fine because it works on another tv.The ceramic caps connected to the hdmi controller ic is reading 39 ohms.Could the hdmi controller ic be faulty(feels very warm to touch).The RCA jacks work normally .Thank you in advance for your assistance..
