Touchscreen/Digitizer Controller Firmware Download

[addmorebacon]

I was having issues with my touch screen and pen, and found an HP forum with a firmware update. Unfortunately, it was firmware for a completely different laptop and now my touch input is inverted along the x-axis (if I touch top center it shows an input at bottom center), along with random presses along the left side of my screen. My laptop was stationary on a desk, working perfectly, and completely messed up as soon as the install happened, so I think I can completely rule out hardware.

I have uninstalled and reinstalled Windows. I have done a BIOS recovery and update, and tried updating all touchscreen drivers. I have used the HP Hardware Diagnostics UEFI. Nothing has worked.

The download was: 20190311_HP_Superman15.6__FW6118T18W00

The install .exe file was was: UpdateMultiDevicesEDID

The simplest and easiest fix would be if I could be provided the touchscreen controller firmware for my specific laptop.

Thanks in advance

@addmorebacon Welcome to HP Community!

I understand that the touch screen is not working.

Do not worry. I will try to fix the issue.

Please perform the bleow steps and check.

Step 1: Confirm the computer has a touch screen

If the screen has never responded to touch, but you think it should, use one of these methods to confirm your computer has a touch screen.

• In Windows, search for and open View pen and touch info. If the Pen and touch section reads No pen or touch input is available for this display, the computer does not have a touch screen.

• Check the product specifications for your computer model on the HP Customer Support website.

• Check the labels on the computer and on the product packaging. Notebook and All-in-One computer models equipped with touch screens are branded with the word Touch or TouchSmart.

Step 2: Enable and reinstall the touch screen driver in Device Manager

Your touch screen might not respond because it is not enabled or needs to be reinstalled. Use Device Manager to enable and reinstall the touch screen driver.

1. In Windows, search for and open Device Manager.

2. Expand the Human Interface Devices list.

3. Right-click the touch screen device, and then click Enable, if possible. If the Enable option does not display, continue to the next step.

   

4. Tap the screen to see if it responds. If it does not, continue with these steps.

5. Right-click the touch screen device, and then click Uninstall.

   

6. Restart the computer to reinstall the touch screen driver.

7. Tap the screen to see if it responds. If it does not, continue to the next step.

Step 3: Configure the touch display

Configure the touch display to identify your screen as a touch screen.

1. In Windows, search for and open Calibrate the screen for pen and touch input.

2. On the Display tab, click Setup.

   

3. Click Touch input.

   

4. Follow the on-screen directions to identify your screen as a touch screen

If the issue still persists, please Install the latest Windows 10 updates.

1. In Windows, search for and open Check for updates.

2. If updates are available, they begin installing automatically.

   

3. When update installation is complete, tap the screen to see if it responds. If it does not, continue to the next step.

If the issue still persists, perform a system reset.

I've completed all the listed steps.

Drivers were all up to date.

The calibration almost fixed the inversion issue, but only the top half of the screen responds correctly, the bottom half receives inputs in seemingly random spots. Also, while it changed the touch input, it made no difference on my Pen input.

Full system reset also did not fix the problem. As I said above, the easiest solution would be a link to the touchscreen/digitizer firmware. It is not listed in the HP downloads.

Thanks again.
