Windows 10: Missing display on second screen since 2 weeks

Hi,

I work on laptop plus monitor asus vs247h. Since two weeks laptop cannot find screen via hdmi. I have chcked monitor with 3 laptops, all windows10 with full system update and every of them has the same issue.

I have also tested 3 working hdmi cables and still nothing.

I did all tests with turning off and on laptop, turning off battery savings, flight mode etc., still nothing.

What is interesting, I have tested this screen with Chromecast and Xiaomi tv sticks and both of them are working via hdmi. I did a test with dvi cable as well and it is also working.

Any idea how to solve this as company laptop has only hdmi-changing company is not an option for now?

Regards

Plugging in second screen makes built-in display + second screen go blank

Hi,



Thank you for posting your query on Microsoft Community.



Please share these details.

1) Are you connecting the second monitor through the VGA or the HDMI port?

2) What is the make and model of the second monitor?



This issue could be caused due to some incorrect settings or due to an incompatible driver. I would suggest you to try these steps and check:



First, I would suggest you to check if you have configured the second screen correctly. It depends on which settings you have selected for the second monitor. You can extend, duplicate or choose only the second screen to be ON. If you have selected only the
second screen to be ON and if the second screen is not compatible, then both the screen might appear black. Refer to this article to check if you have configured the second screen correctly:

I would suggest you to uninstall and reinstall the graphic card driver from the manufacturer website and check, if it works. Refer to the following steps to uninstall the graphic card driver from the Device Manager.

a. Click on Windows key + X and then, select Device Manager.

b. Locate and expand “Display Adaptor” in the Device Manager Window.

c. Right-click on the “Display Adaptor” and click on “uninstall" the graphic card driver.

d. Restart the computer and check, if it works.

Hope this answers your query. You can write back to us for further queries/issues related to windows and we will be glad to assist you further.

 

second display configuration issue

Hi All,

My configuration:

Windows 10 Pro x64
AMD Radeon HD 7800

Latest updates and video drivers installed, no hardware changes for 2+ months, latest significant Windows update 2 weeks ago, latest AMD video driver installed at least a week ago.


I have 2 identical displays connected via DVI to Windows PC over several years already with "Extend displays" configuration, and suddenly this configuration stopped working a couple of days ago when I was in the middle of doing something. Windows just replaced it with "Duplicate displays" configuration.


During PC startup I see BIOS diagnostics on both displays. Windows detects 2 displays. "Show only on 1" and "Show only on 2" options work as expected.


Problem: "Extend these displays" results in display 1 going blank and display 2 shows it's part of the image.


AMD Eyefinity (which creates virtual desktop over several monitors) works fine - which suggests that problem maybe only with Windows configuration.


What is done:

• checked cables
• removed and installed again latest AMD drivers
• removed second display from the System Devices, refreshed hardware list and added display again - now I have "Generic PnP monitor" and monitor with correct name in Monitors section
• searched for latest drivers for monitors and display adapters from Device Manager, nothing found

Next I replaced one monitor with monitor from different manufacturer, and everything works as expected - "Extend these displays" configuration shows extended image.


Any ideas what else can be done to fix the problem?


Thank you in advance.
