Fix Windows 10 OS errors with Fortect:
PCs can be used for presentations using the projector duplicate feature. However, the option is faulty sometimes. For example, a few Windows 10 users have complained that the duplicated screen is not working during projection.
Sometimes, the HDMI connection might be the problem because the built-ingraphicsinterfere with your system.
That being said, please find below a list of causes and solutions that should help you restore the projector duplicate feature on your device.
Why is the duplicate display not working?
From complaints and observations, we realize that any of the following factors could be responsible for the duplicate screen not working:
What can I do if the duplicate screen is not working?
Before going through the suggested solutions, we recommend checking your cables and ensuring they are properly connected at all ends. The aim is to eliminate the problem if loose cables and connections cause it.
Also, as an alternative to save you troubleshooting, use a cable splitter. A splitter cable has two ends. One end goes to your monitor, while the other goes to your projector, TV, or second monitor.
After connecting bothdisplays, the same signal will be sent to both simultaneously, so you’ll duplicate yourdisplayautomatically.
If you want a reliable and cost-efficient solution, we recommend you try theTB VGA Splitter Cable Converter. The tool sends an identical VGA signal to 2 separate VGA displays, allowing users to view the same image on two monitors.
1. Update your drivers
Also, users mentioned that the DisplayLink port replicatordriverwas outdated, which caused this issue to appear. To fix this problem, you need to ensure that all yourdriversare up to date. Visit your laptop manufacturer’s website and download the latestdriversfor your model.
If downloadingdriversmanually seems tedious or you don’t know how to do it properly, you can always use tools such as Outbyte Driver Updater.
Using this tool, you’ll update all yourdriversautomatically with just a few clicks.
Besides, you’ll get recommendations for only the compatible drivers for your device. Needless to say that this is the safest and quickest solution to fulfill this job.

2. Make sure that both monitors are using the exact resolution
If you can’t use the duplicate projectorfeatureon yourPC, perhaps the problem is yourdisplayresolution.
Several users suggest that both monitors must use the exact resolution to duplicate your screen.
Once both monitors are set to use the same resolution, the issue should be resolved, and you can duplicate your screen without problems.
3. Disable the built-in graphics
Check if the duplicate projector feature works properly now.
Many laptops and somePCshave built-ingraphicsavailable. However, according to users, Intel integrated graphics can sometimes cause problems with the duplicate projector feature on yourPCand prevent you from using it.
4. Use Hardware and Device Troubleshooter
Once the troubleshooting process is finished, check if the problem is still there.
5. Perform an SFC and DISM scan
Once the SFC scan is completed, check for the problem.
We also have a guide on what to doif the sfc/scannow stopsout of the blue.
If the duplicate projector is still unusable, try running a DISM scan. To do that, follow these steps:
Once the DISM scan is finished, check for the problem. If you couldn’t run an SFC scan earlier, try to run it now and check if that solves your problem.
This solution is helpful if file corruption is causing the error. After all, the OS installation often gets corrupted for various reasons.
6. Install the latest updates
Windows will now check for available updates and download them automatically in the background.
After downloading the updates, they will be installed as soon as you restart your PC. Once your system is updated, check if the problem is still there.
7. Perform a System Restore
Remember that a System Restore will work only if this problem started appearing recently.
The projector duplicate is a useful feature, but sometimes issues like the duplicate screen not working can appear. However, we hope you’ll solve the problem using one of our solutions.
