There’s no need to panic if your DisplayPort display doesn’t show anything when you connect to your device. In this article, we will discuss a few options you could use to fix the DisplayPort not working on Windows 10.

These fixes work for most Dell, HP, Samsung, LG and most other monitors.

Fix 1. Disable power saving on Dell

It’s possible that the DisplayPort feature isn’t working on your Dell machine because the monitor soft boots, resulting in a dysfunctional DP.

This could be a software / hardware issue, so we’re going to take a look at both the operating system and computer in this post.

To fix DisplayPort not working on Dell, open the On-Screen Display >> press the Menu button to go to Display >> select Power Saving >> Turn it OFF >> Save and Exit the On-Screen

While this fixes has been tested and found to work on Dell and HP monitors, you may want to try it on your machine to see if it works.

Fix 2. Unplug the cord

Another fix to try out on Dell machines is to: Connect both DisplayPort and HDMI cables to the monitor; Start Windows with HDMI Mode; make the switch to DP via the OSD (you’ll see no message, just sleep mode and black screen); remove the power cord from the monitor (don’t use the switch); wait for some time; Re-insert the power cable and Restart.

Fix 3. Update GPU BIOS and drivers

Another way to fix the problem is to update the BIOS of the GPU.

We had to use a GTX 970 after we updated the drivers.

If it does, you don’t need to touch the drivers.

When the BIOS upgrade didn’t work for us, we replaced the NVIDIA drivers, then we installed a monitor driver.

You should use NVIDIA’s Graphics Firmware update tool for DisplayPort.

You could try using a different monitor, with the same DP cable and computer. If it works the same, try testing the monitor and cable with another computer, and if that doesn’t work, try swapping the cable with a different one to see if that fixes the problem for you.

Fix 6: Rollback updates and/or change the refresh rate

If you’ve recently updated the software that controls your Amazon store, we recommend rolling back the update to see if something is broken by the update.

You would also want to change the refresh rate on your monitor to see if it works.

Roll back the driver update by clicking Properties >> select the Driver tab >> if there is an option to roll back, click it.

Fix 7: Update the driver from the manufacturer’s website

If you don’t have a DisplayPort video connector, but you do have an HDMI video connector, here is how you can resolve the issue: Search for the Model and OS compatible driver >> Search for the Model and OS compatible driver >> Download and uninstall the old Intel graphics driver >> Install the newly downloaded driver >> Restart your PC.
