    HDMI to HDTV ( Windows 10 )


    Hi,
    I just purchased a new HDTV & connected it to my desktop w/ a HDMI cable ( the connection is via a splitter, one input to monitor the other to the TV ). Everything seems to be working but when I look @ playback devices it shows the TV that was previously connected as the one currently detected. There is no indication that a new device was connected. Any help would be appreciated. Also, graphics card drivers are up to date.

    Thanks

    I'm not sure that a splitter will work. The graphics card reads an EDID (https://en.wikipedia.org/wiki/Extend...ification_Data) from the monitor, and I don't know whether it'd happily read two EDIDs.

    Do you have an alternate means of connecting the monitor to a separate output of the graphics device?

    The monitor ( HP w2207h ) only has VGA or HDMI. VGA isn't very good. The thing is, both the monitor & TV are working fine being connected to the splitter amplifier. When looking @ playback devices in Sound it shows it is connected but the device name is the name of the old TV. Maybe the graphics ( 750ti ) works but doesn't "recognize" the change in TVs due to a splitter being used. Thanks for replying.

    Why did you use a splitter? Why not just feed the TV from a second video output of your video card? The PC will only ever see one device/monitor when using the splitter. You can only ever mirror what is displayed on both too. Unless that was your intent? If the two monitors have different resolutions it will be an issue, you can only ever set one resolution to be used by both displays.

    TV only has HDMI & Graphics card only has 1 HDMI output. I guess I could get a DVI ( graphics card has DVI )> HDMI cable for the monitor. Still, it did recognize the older TV. Thanks.

    I run 3 monitors, all are DVI. My video card has 2 DVI and one mini HDMI. I use a Mini to normal HDMI cable plugged into an HDMI to DVI adapter for one of my monitors.
    Normally there is no sound from DVI, but on video cards that also have HDMI, it will sometimes work. They send an HDMI signal out over the DVI port or something?
    You might lose the sound on the monitor connected with the DVI to HDMI cable. You won't know it until you try it. If your using dedicated PC speakers (like me) it won't be an issue.

    I could try that as my graphics card has 2 DVI. I have USB speakers so sound isn't a problem. Just have to get DVI > HDMI cable.
    I use the splitter ( which does work great ) since my previous computer only had HDMI. Thanks.

    The other advantage to running from your graphics card with no splitter is, you can switch to "Extend" mode and run the two displays independently. You could watch a video on the TV and do Internet on the PC monitor at the same time etc.

    HDMI splitters (as well matrixes, switchers etc) recognize the last plugged output. so if you want to prioritize your monitor with the splitter, plug the TV first and then the monitor. it should give you the EDID of the monitor that way.
