Huion H640P stuttering/lagging pen detection

I've been using my tablet for about a year and a half and until recently ive never encountered an issue, unfortunately today when trying to draw my pen started stuttering a bit, the light also tends to flicker at the same time the pen stutters, at first it wasnt that bad but it got worse over time, sometimes it randomly stops happening but then starts again sometime later, i tried to fix it by reinstalling the driver, restarting my computer y reconnecting the tablet but i found no success.

I usually stick to Krita for drawing but testing this on other applications such as paint, sketchbook and adobe animate yielded the same result.

Ive always taken extreme care over my tablet and i have no clue how this could have happened, if anyone could help i would appreciate it very much, i also put 2 short-ish videos below of me trying to make a few simple lines and even writing my name and getting too much stuter to work properly.

  • Hi Ally Lee, I'm sorry to hear that you are experiencing problems with the tablet. May I clarify with you if it happens without the driver installed. What version of the driver you are using. No worries, we will get it sorted.

    Best Regards,

  • Hello! i wrote a reply but it hasnt sent yet and now im almost certain i somehow didnt send it, apologies if im mistaken and 2 nearly identical comments show up.

    the tablet just doesnt seem to work without the driver, im not sure if this is how its supposed to be or if im doing something wrong, i was originally using the oldest version (Driver_14.8.165) but after uninstalling it i decided to download the newest one (Driver_15.5.3.444), unfortunately the suttering/lagging persisted.

  • Hi Ally Lee, thank you for your reply. Kindly follow the steps below:

    1. Please exit from the Huion tablet driver and don't open the said driver. You can do this by right-clicking the Huion Tablet driver icon from the lower-right corner of your screen and clicking "Exit";

    2. Install the Huion TabletQC tool which you can download from this link: Huion TabletQC Test
    3. Check if the parameters on the left-hand side appear on the QC software. If you don't see the parameters, please unplug and plug your tablet back in until the parameters appear, or reopen the QC software again if needed.
    4. Draw on the QC software. You can choose from the "Menu" at the top using your mouse to have pen pressure or use different colors as you draw. Or press the following keyboard shortcuts:
      a. F - enter or exit fullscreen mode (you'll have more accuracy when on fullscreen mode)
      b. B - change brush
      c. C - change color
      d. E - clear or erase
    5. Try pressing the pen buttons and the express keys on the tablet (if your tablet has press keys). Test the dial, touch bar, or slider if your tablet has it, and use your pen to test your tablet's soft keys (if your tablet has it) and check if the parameters change.
    6. Using a phone or other external camera devices, take a video as you perform all of the steps mentioned above and send it to us (we recommend you upload the video to a cloud storage such as OneDrive, iCloud, Dropbox, or Google Drive and please grant permission to anyone who has a link to view it). Please don't use screen recording; it is essential that we can clearly see both the tablet and the display screen as you perform the test. Please refer to the screenshot below on what to observe and do in the TabletQC software.

  • Hello apologies for my late response as ive been a tad busy, i recorded a video on my crappy phone so apologies if the lighting looks too harsh or its low quality, i did my best with what i had.

    everything worked perfectly except for when it came to properly detecting my stylus.
