Monitor Resolution Changes After Laptop Awakes From Sleep

[Jagstyles]

I'm using my HP Spectre x360 laptop plugged into a HP Envy 4k Monitor via HDMI. The resolution is fine when I first plug the HDMI cable and it looks amazing.

However, whenever my laptop falls asleep and I return to my desk to awake my laptop, the HP Envy display comes on but now has a lower quality resolution. I then have to unplug the HDMI cable and plug it back in at which point it restores the 4k resolution.

Any idea why this happens and how to prevent it?

Thanks

Thanks for reaching out to us on HP Support Forums. 🙂 I came across your post and would like to assist.

I understand that you have an HP Spectre x360 series laptop. I read that you have connected an HP Envy 4k Monitor via HDMI. The display seems fine until the laptop goes to sleep mode. The display quality is low when the laptop resumes from the sleep mode. If the HDMI cable is unplugged and reconnected, the display seems to be alright. 

Seems like an issue with the display driver. The resolution seems to go low if the laptop falls asleep. 

Please let me know the exact product model no. This link will help you to find the model no: http://hp.care/2bygf7l

I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

• Open the device manager.

Figure :  Example of  the display adapters in the device manager.

• Expand "Display adapters". Right click on the display drivers and select uninstall. 
• Close the device manager and restart the laptop.
• You may download and install the display drivers from this HP link: www.hp.com/drivers

I sincerely hope this fixes the issue. Let me know how it goes. Cheers! 🙂
