Spectrex360 15 4k screen dimmed down after update

[Preetham999]

My HP Spectre x360 15" got software updates recently, before updates the maximum brightness setting on the screen showed more vivid colors on the display, which I believe is the 4k display mode. Lowering the brightness by one step just showed the normal colors, but after the update, the max brightness-4k does not work. It's not a hardware issue because when I restore the laptop using the recovery file before update, the vivid mode works. But the laptop keeps auto updating, leaving me with the normal colour display, is anyone else facing this issue? I really liked the vivid mode as it let the colours pop on the screen, but now it's just dimmed out light. Please help.

Welcome to the HP Support Community.

Let's try increasing the brightness of the laptops and check if that makes a difference.

Also, you may want to perform a colour calibration to get the screen into your preference:

Before you start, make sure your monitor has been on for at least half an hour, so it's warmed up properly, and clean your monitor.
 

1. Right-click on the desktop and select Display settings
 

2. Click "Advanced display settings" at the bottom of the settings window.
 

3. Verify that your monitor is set to the recommended, native resolution. If it's not, set it to the recommended resolution at least for this calibration process.
 

4. Click "Color calibration" at the bottom of the advanced display settings window.
 

5. Click Next to start the colour calibration.
 

 

The wizard will walk you through adjusting your colour settings. You'll:

• Set the display to the factory default colour settings, if your monitor allows you to do that
• Adjust your display's gamma to match a sample image
  
  
   
• Adjust the brightness and contrast
  
  

Adjust the colour balance



6. At the end of the wizard, click Finish to save your settings.
 

You'll then be able to calibrate ClearType for sharper text.

Hi, I have tried all of these. None of them worked.

The resolution is set to 4k but the display does not look as vibrant. However, when I roll back the intel UHD graphics in display adapter(device manger), the display works like before but now I can't increase or decrease the brightness.

Let's uninstall the display drivers:

1) In the search box on the taskbar, type Device Manager, and then select Device Manager from the list of results.

2) In Device Manager, expand Display Adapter.

3) Right-click on the Display Adapter, and then select Uninstall device > Delete the driver software for this device check box > Uninstall.

4) Restart the computer.  

Let me know if this helps.

I have uninstalled the drivers and restarted, but it goes back to the previous issue again which is dull colours. 

For now the only solution I found  is to keep rolling back the drivers everytime I restart the laptop

Let's update the BIOS: https://support.hp.com/in-en/document/c00042629

Also, what is the Windows version installed on your computer?

Does the display gets back to normal everytime you roll back the driver?

I suggest you download and run the HP Support Assistant from this Link: https://www8.hp.com/us/en/campaigns/hpsupportassistant/hpsupport.html?jumpid=va_r602_us/en/any/psg/p...

HPSA will automatically search for all the latest drivers for your Notebook

1. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.

   

2. Click Check for updates and messages to scan for new updates.

   

3. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.

4. Click the update name for a description, version number, and file size.

5. Select the box next to any updates you want to install, and then click Download and install.

Thank you
