What computer model?
What operating system?
Uninstall DDM, reboot the computer when done
Open the Device Manager- Monitors. What is listed? It should show the SE2717H. If not, the driver did not install. Go to where XFV95 decompressed. Find the INF file. Right click it, click install. Then recheck the Device Manager- Monitors.

Hi Chris, thanks for the advice. I am using self assembled computer on Core i7 CPU and running 64-bit Windows 10 pro. DDM was uninstalled and then reinstalled and on the device manager, it shows SE2717H/HX(HDMI) but it did not enable automatically and I have to manually enable the driver. It seems okay for now and will observe few more days to see if it will resurface.

I have another issue though and notice the monitor flashes to black screen intermittently for about 2-3 seconds. It is very annoying as you are unable to continue until it returns to normal screen. Please advise if there is a fix to this issue.

many thanks again.

Leon

Can you replicate the flashing issue when testing on another computer? What video card is in that self assembled computer? List all the video out ports on the video card. Ideally, you want to test both the SE2717H HDMI in port and the VGA in port, one at a time on multiple systems.

LG was connected exactly the same way as SE2717H, i.e. to Nvidia GTX 1060 HDMI out port.

I have not tested on the #2 HDMI out port and also not tested on another computer which I will try out later and will revert if the issue still persist. I read on some forums that others have had same experiences with other Dell monitors but not sure if Dell had provided the solution to the issue.

I didn't experience flashing issue on LG monitor connected to the same self assembled computer.

As for the graphics card, i have a Asus Nvidia GTX 1060 graphics card and it has 2 HDMI, 2 display ports and 1 DVI-D. I also noticed that if I maximize the web browser to full screen, it tends to have the flashing issue more frequently.

And was this LG connecting to the Nvidia GTX 1060 HDMI out ports? As this SE2717H is?
Nvidia GTX 1060 HDMI 1 out --> SE2717H HDMI to HDMI cable --> SE2717H HDMI in port

Or was the LG connecting to the DP or DVI-D? If not connected to the Nvidia GTX 1060 HDMI out ports, its apples to oranges.

And did you test the #2 Nvidia GTX 1060 HDMI out port?
Nvidia GTX 1060 HDMI 2 out --> SE2717H HDMI to HDMI cable --> SE2717H HDMI in port

Consider testing another HDMI to HDMI cable.

Can you replicate the flashing when using a different computer?

There are no known SE2717H systemic issues.

Hi Chris,

sorry to revert late on the test with other PCs.

i have tried using a Dell notebook and the flashing black screen is still present.

i noticed that the display driver (DELL SE2717H/HX(HDMI) is not enabled every time i logon to windows and i have to enable it manually.

Appreciate your advice.

Thanks,
