  1. HDMI-usb C connection between laptop and monitor doesn't always work


    Hi there,

    I have a razor blade stealth 13" laptop and an LG monitor that has an HDMI port. My laptop has USB C ports and no HDMI. I connect my monitor to my laptop with a cable that has HDMI on one end and USB C on the other end. When I connect the monitor to my laptop, my laptop doesn't always recognize the monitor on the first try. It takes like 3 times for me to connect the cable to my laptop and disconnect it till finally my laptop makes the connection sound and recognizes my monitor.

    I am using windows 10 Home and my drivers are all updated. Is there a way to fix this problem? thank you.

    :)

  2. Odd issue with HDMI connection to monitor

    I have a HP Spectre x360. This laptop doesn't have a HDMI port. Instead I use a USB-C to HDMI/VGA adapter. No issues until the recent 1903 Feature Update. After this update, my laptop will not recognise the monitor that is connected.

    I have troubleshooted in the following ways:

    - Connecting a Samsung Galaxy phone to the monitor via the same HDMI and USB-C adapter - Success, the adapter, cable and monitor must be working.

    - Connecting my laptop to a different monitor using a VGA connection with the same adapter - Success, the laptop can at least handle a second monitor via VGA.

    - Uninstalling and reinstalling laptop graphics drivers - no success. When connecting the monitor via USB-C to HDMI, in Settings>System>Display - the "Rearrange your displays" visual simply doesnt appear.

    So it looks like my laptop is struggling with HDMI input - but via a HDMI to USB-C adapter, since there is no HDMI port.

    Could not find a way to restore it back to before the update.

    Any help appreciated.

  3. HDMI and USB-C ports are not working

    Hi Robert and John,

    I will try that Robert as soon as I understand how. And yes my screen blinks and no affects to other monitor. Just says vga and hmdi are inactive.

    And for John. Something got right, since Windows doesn´t anymore say that it doesn´t regocnice USB-C port. But yeah, neither still works and no second screen.

    HDMI-usb C connection between laptop and monitor doesn't always work

    HDMI Disable

    Thanks Greg for you quick reply!

    I've update the drivers on my Windows. I use the same cable with no issues with the following configurations:

    • Laptop with no USB-C Hub. connected through laptop hdmi port to monitor.
    • Laptop with Anker HUB 7 in 1 USB-C connected throught laptop hdmi port to monitor
    • Laptop with Anker HUB 7 in 1 USB-C connected throught USB-C hub hdmi port to monitor
    • Laptop with Flepow 12 in 1 USB-C connected throught USB-C hub hdmi port to monitor
    After that test I can prove that

    The HDMI cable works and my monitor works. The only enviroment when my monitor appear have not signal is when the USB-C Hub is connected but only the Flepow.

    If I disconnect the Flepow from my laptop and the laptop is connected to my monitor I have extended view in both monitor (Dell SP2309W and laptop builtin) after that I connect the Flepow extended vision works but if I restart the laptop with hub-c connected
    I the laptop hdmi port do not send signal.

    I send mail to flepow support but do not receive information. I think that is soming with configuration. :S

    Thanks!
