I have a ViewSonic XG2402 gaming monitor. On my PC it feels great with unnoticeable amount of input lag but when I plug it into my Acer Predator Helios 300 laptop via its mini display port I notice a bit of input lag. Everything else is fine. Any idea of what is causing this? Thanks.

    Tried changing resolution and refresh rate on both the monitor and the laptop screen, no change. 
    If it's the mini port, is my laptop just defective?

    Try these steps.

    Please perform the following steps and check the CPU usage :
    >>>Power Reset
    Disconnect the charger. Please check for a battery reset PIN hole at the bottom of the device. The reset hole would have a battery symbol next to it. Insert a paperclip into the hole and press for four seconds. Let the computer sit for 5 minutes with no power. Reconnect and monitorthe CPU usage. If there is no pin hole then press and hold the power button on the unit for 12secs. ​


    >>>End Task of running programs and Disable Startup program in task manager. This fix can help you quickly end high CPU usage issue when your device becomes extremely slow or even get stuck with running programs:

    Press Ctrl + Alt + Del keys at the same time to bring up Task Manager; 
    Select Task Manager > Check and select programs that are taking high memory and CPU usage > Click End Task to close selected programs or apps. 
    Click on Startup on Task Manager > Select and right-click on unnecessary programs or apps > Select Disable to stop them running from Startup.


    >>>Run DISM command to decrease high CPU usage

    Right-click on Start and select Command Prompt (Admin), sign in with your administrator account;

    Type: DISM.exe /Online /Cleanup-image /Restorehealth and hit Enter;

    Type: DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess and hit Enter;

    Type: sfc /scannow and hit Enter.


    >>>Disable Superfetch and Windows services to fix Windows high CPU usage

    Go to Services tab and click Open services;

    Navigate and locate Superfetch, right click on it and select Properties;

    Click Stop to end the Superfetch service and click OK to confirm the change.


    >>>Press Win + R to open Run dialog > Type: msconfig and click OK;

    Much appreciate the reply. Could you tell me what all of that is doing? And what problem you think it's happening?
