Windows 10: Only "Mobile PC Display" showing under Display

I don't know what happened to my display, but once I reinstalled Windows 10, the display (under Control Panel -> Hardware and Sound -> Pen and Touch -> Display tab -> Display Options -> Display drop-down box) only shows that I have a mobile pc display. But I know that is not correct. And what's worse is that the tablet buttons are not installed in my system. Those two exact problems might be why only the right side of my touch screen is working. I already have the correct driver for my touchscreen laptop so I'm CERTAIN that's not the problem. Can someone (anyone!) help me with solving the first problem and redirect me toward the tablet buttons I need for my Lenovo B50-30 Touch in order to solve the second? I want my full functionality back on my laptop. Thank you very much.

Sincerely,
A desperate [rookie] user,


P.S. (IMPORTANT) Please don't tell me to service my device. I have a STRONG feeling that would not be necessary.

How are you making out

Only "Mobile PC Display" showing under Display

Hello Jay,

This issue might have occurred due to corrupted touch screen drivers.

In order to understand the issue more clearly, We would request you to kindly provide us with the following information.

• 
  Do you see any exclamation mark in Device Manager?
  

To check for any exclamation mark in Device Manager,
please follow the steps given below.

• 
  Press Windows key + X.
  
• 
  Click on Device Manager.
  
• 
  Select Human Interface Devices.
  
• 
  Check if you see any errors.
  

We would suggest you to try the following the methods below:

Method 1:

Run Inbuilt Hardware and Device troubleshooter. Follow the steps given below.

Note:
If your computer is having problems with a recently installed device or other hardware, try using the Hardware and Devices troubleshooter to fix the problem. It checks for common issues and makes sure that any new device or
hardware attached to your computer was installed correctly.

• 
  Press Windows Key +R, type
  Control Panel.
  
• 
  Type troubleshooting
  in the search bar, click on troubleshooting.
  
• 
  Click on Hardware and Devices.
  
• 
  Follow the steps from the wizard to run the troubleshooter.
  

If the issue persists, follow method 2.

Method 2:

Step 1:

To diagnose whether this issue occurs in
“Safe Mode”, let’s reboot the computer in safe mode and check if the issue appears there as well.

Safe mode is a diagnostic mode for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. This helps us in identifying whether the issue is due to some
third party programs conflict. The word Safe mode appear in the concern of your monitor to identify which windows mode you are using.

Follow the steps given below:

• 
  Type settings in search and click on Settings.
  
• 
  Click Update and recovery, and then tap or
  click Recovery.
  
• 
  Under Advanced startup, tap or click Restart now.
  
• 
  Once your PC restarts, on the Choose an option screen, tap or click
  Troubleshoot.
  
• 
  If you don't see the Startup Settings option, tap or click
  advanced options.
  
• 
  Tap or click Startup Settings.
  
• 
  Tap or click Restart.
  
• 
  On the Startup Settings screen, choose the
  Safe Mode.
  
• 
  Sign in to your PC with a user account that has
  administrator rights.
  

Step 2:

If the issue does not appear in safe mode, place the computer in clean boot state and check if the issue reappears.

Placing your system in “Clean Boot” state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot.

How to perform a clean boot in Windows

If the issue does not occur in “Clean Boot”, then you may determine which application/service on the computer is causing this issue. This can be done by following the instructions for
“Windows 8.1 and Windows 8” given in the section “How to determine what is causing the problem by performing a Clean Boot” from the same given link.

Note: Refer "How to reset the computer to start normally after clean boot troubleshooting" to reset the computer to start as normal after troubleshooting.

Let us know what happens.

 

Have you tried using Lenovo System Update utility to scan and download missing drivers for your unit? It works like a champ on my X220 Tablet and T420 notebook. It sounds like your displays drivers are OK, but you probably need to install touch and/or button drivers. You can find the tool on the Lenovo Support site, and you can also conduct an online scan of drivers and so forth there, too. I provided a link to the tool for my laptop in the first sentence of this post: try it, it may work for yours, too.
HTH,

Yeah. In fact, I did. But the update link said my laptop is not eligible for some reason. See, my laptop is a B50-30 Touch. That might be why.

 

Then, please download and use the driver scanner in the Windows Update MiniTool. I've found it to be as good or better than my two favorite commercial tools. Sorry for your difficulties. I thought your model was newer than mine...
