    TV as duplicate monitor


    Hello, I hope you can help! I have a Dell Inspiron 3847 desktop PC. I ran an HDMI cable from the single HDMI port on the back panel of my PC to the HDMI-2 port on the TV, I have set the PC display settings to duplicate the screens and all was working fine, I switch to input 2 on the TV, change the audio output on PC to TV and im using my TV as a 2nd monitor. Until now... Now I get a no signal message on the TV when I switch inputs, I have not made any changes to PC or installed/deleted anything. I have swapped out the 1 + 2 hdmi ports on the tv and both are operational. I have purchased a new

    Duplicating 1440p monitor onto 4k TV - What will happen?

    I want to duplicate my monitor onto a TV. I wish to run the monitor at 1440p.

    What will happen when I duplicate the display to a TV.

    I know if the TV is 1080p, it would downgrade my monitor to 1080p

    If the TV is 4k, will it downgrade the TV to 1440p? (this is what I want it to do, I just want to make sure this is what will happen, without any problems or forcing to have to have the monitor go below 1440p or something)

    How would that work?

    I'm duplicating the monitor to the TV. Duplication always uses the lowest resolution of the two devices

    TV as duplicate monitor

    Windows 7 - Cannot duplicate the monitor to my Samsung LCD

    Hello, everyone!
    I'm trying to duplicate a monitor to my Samsung LCD but Windows 7 says that it's unable to save the changes each time I click APPLY after selecting DUPLICATE screens option. WIN+P also doesn't work - I can only see what's going on either on my pc monitor (in Projector Only mode) or TV (in Computer Only Mode).

    Both TV and monitor are using 1920x1200 resolution and they are connected via HDMI 1.4, Graphic Card is MSI Radeon 6950.

    Any suggestions would be highly appreciated.
