PC HDMI problem when boot up with Kamvas 13 plugged-in

Hello,

I've recently purchased a Kamvas 13. (S/N:B2DE6SH03859)

Happy with the tablet in general, however I'm experiencing a problem:

Whenever I cold boot my PC with the Kamvas plugged in to the HDMI port, the HDMI port fails to start operating.

Since the HDMI port is inactive, it becomes impossible to use the Kamvas or any other device plugged to the HDMI port.

(The Kamvas displays the "No Signal" message in this case.)

So in order to prevent this issue, each time I am to cold boot the PC I first unplug the Kamvas and then do the cold boot. I then plug in the Kamvas to the HDMI port and it just works fine.

(Restart or unplug-plug does not solve the issue, by the way. Only a cold boot with the Kamvas unplugged fixes the problem.)

Though this solves the issue, it is far from being convenient as a solution.

I shouldn't have to remember this extra step before each cold boot. Besides, this plug-unplug routine may cause an early wear out in the port and the connector.

Help would be appreciated.

P.S. I have the latest driver for the Kamvas and latest updates for Windows 10. No problem with the 3-in-1 cable or the HDMI port either, since the tablet works fine unless the PC hasn't been cold booted with the Kamvas plugged in.

P.S. This problem occurs only with cold boots. Restarts or wake ups do not cause this issue.

 

 

 

 

 

 

 

 

 

 

 

  • Hi Istemihan, Please try to check the following:


    1. Plug the HDMI cable into another HDMI port(in case the HDMI port on your graphics card is defective)

    2. Change a new HUION 3in1 cable(in case the cable is defective)

    3. If you have a HUION USB C to USB C cable, using it to connect the tablet to your computer, but please make sure the USB C port on your computer at least supports USB3.1 GEN1 data transfer protocol and DP1.2.

    4. Uninstall and reinstall the driver(in case the driver does not install properly)

  • Hi Jessica,


    Here are my answers:


    1. As I've already stated in my initial post, there doesn't seem to be a problem with the HDMI port. Because if I make the cold boot with the Kamvas UNPLUGGED, the HDMI port starts operating without any issues. I then plug the Kamvas into the HDMI port and everything's OK.


    2. As I've already stated in my initial post, there doesn't seem to be a problem with the 3in1 cable. Because if I make the cold boot with the Kamvas UNPLUGGED, and THEN plug the Kamvas via the 3in1 cable, everything works nicely.


    3. I'm not using the USB-C cable. I'm using the 3in1 cable, hence the HDMI issue.


    4. I tried the driver uninstall-reinstall, it hasn't changed anything.

     

     

     

     

     

  • UPDATE:

    Although the problem still continues, I've made a new observation about this issue and found out a new partial solution -other than the previous solution mentioned in my previous post. If anyone else reading this post has the same problem, the new observation and solution is as follows:

    I observed that this cold boot HDMI problem occurs only if the PC was previously shut down while the Kamvas was still ON. When the PC is shut down, the Kamvas automatically switches to the power saving mode, its power light turns into red and then goes off completely. But although the light goes off completely, it seems it is kind of in a sleep mode. And it seems that it is this sleep mode that causes the problem. If you boot up the PC while the Kamvas is in this sleep mode, the HDMI problem occurs -that is, the HDMI port fails to start operating.

    SOLUTION: Before you shut down your PC, remember to switch off the Kamvas first -and then you can shut down the PC. There you have it, this is the solution. By switching off the Kamvas first, before shutting down the PC, you ensure that the Kamvas does not switch into its sleep mode. So the next time you boot up your PC while the Kamvas is still plugged in to the HDMI port, the HDMI port starts operating without an issue and you should be able use the Kamvas without problem.

    Hope this helps anyone experiencing the same issue. 

     

     

     

     

  • Hi Istemihan, Thank you for your clarification, now we understand what you are experiencing with the tablet and we are sorry about that. We have reported your feedback to our technical department team and will keep you updated once we hear from our technicians.

  • Thanks Jessica, Hope to hear from you soon.
  • Hi Istemihan, Our technician has tested it. When he shuts down his PC, does not switch off the Kamvas first, it mean the tablet is still on, then he restarts the PC, the tablet connects properly and does not show " no signal. How about connecting the tablet to other computer to check. If the issue still exists, please take two videos, one is for switching off the  Kamvas first then shut down the PC and restart the PC, the other one is for shutting down the PC with the  Kamvas is on then restart the PC, that can clearly show what will happen to the Kamvas after restarting the PC.

  • Hi Jessica,

    As you suggested, I tried it with another computer, and didn't see any problems this time.

    So I guess this issue does not occur on every computer. (Obviously, otherwise you would have been hearing about this complaint more frequently).

    So something should be triggering this issue on some computers, like in my case. I don't know how we should proceed from here.

    P.S. As for the other computer I tried and had no problems with: The tablet actually shows that "No Signal" message with that PC too, however briefly, only during the PC's BIOS boot stage. After the OS kicks in, the tablet turns back to normal. So for the PC that I have the problem with, the OS kicking in does not help it somehow.

     

     

     

     

  • Hi Istemihan, Our technicians advise that the tablet showing  "No Signal" message briefly is normal, as long as the display can work properly in very short time, we think the tablet is working.

  • Oh no Jessica, u got me wrong. That brief message was with the other PC that I did NOT have the problem with. I know that a brief message is not a problem! I experience this problem with my own PC. Anyway, I don’t think we’ll be able to come up with a solution. I’m not returning the tablet, since I am able to use it by following the steps I mentioned in my previous posts. But I am experiencing this inconvence. However I see that there’s no point in posting furthermore. Thank you anyway P.S. I agree the tablet is “working”, I haven’t suggested otherwise. This whole title was about an inconvenience I am experiencing. I was trying to find out a solution to an inconvenience I am experiencing.
