    For years I've used a 32" flat screen TV as my PC monitor. Recently I bought a new 55" TV. It works great as a monitor except the mouse pointer lags and when looking at a video, say on YouTube, voice and video aren't in sync.

    The resolution is 1920x1080. The problem still exists if I lower the resolution.

    My computer is old. It has a 2core processor and 6 GB of RAM. It runs Windows 10 64bit. See specs below.

    It's not a problem with the mouse itself. I changed the battery and that didn't help.

    first I'd make sure you windows is up to date....from your posted specs, you're 2 updates behind. Once the OS is updated then check for your issue.

    How is your TV connected to your PC? Check the port for specs on what type of cables version you need to use. Then check what cable version you're currently are using.

    Sounds like you are attempting to play HD content which your PC can't handle. Open Task Manager and check the cpu usage. Very likely you will see that the cpu is running at or near 100%. You can also check the processes tab to see which process(s) are using the cpu.

    Also it may be using motherboard video that is inadequate to drive the 55". If he added a video card it might work. I have an old Dell SC430 with a Pentium D 3.4Ghz and a RadeonHD6350 vid card (512mb) hooked to a sharp 40" HDMI with no problem on you tube.
