Windows 10: a vga monitor

hi

I purchased a better graphics card for one of my pc. s regretfully I sold it on. this was a gtx 980.

now the new gtx 1070 will not recognise my vga monitor.

I have tried running it through various adapters . i.e vga to dvi and hdmi to vga. hdmi to dvi. all no good.

if I connect to the onboard graphics its ok. luckily I have other pc to connect to and the hdmi works fine on them.

but not the vga monitor.

win 10 does not detect the monitor at all through the new card .

tried to run it as a second monitor. win10 does not detect it.

please help its driving me insane.!!!

should I roll back drivers for the gtx 1060 ?

not selling the monitor as its a great 28" viewsonic

regards

m

VGA Port Not Broadcasting to Second Monitor


Machine: Lenovo - Ideacentre 300S Desktop - Intel Core i3 - 4GB Memory - 500GB Hard Drive
OS: Windows 10
Processor Model: Intel 4th Generation Core i3
Graphics Card: Intel HD Graphics 4400

Backstory: I had my computer setup and working properly with dual monitors. I needed to use my work computer with the my monitors, so I unplugged both without shutting down my desktop. When I went to plug in the monitors, I had some trouble getting them to display. I eventually got my primary monitor working via a HDMI cable. However, the VGA connected monitor was not being detected.

Problem: I've tried to use the Windows Key + P to setup the computer for extended desktops. However the monitor is still not detecting a signal from my machine and the machine does not detect the monitor.

• I have tried uninstalling and reinstalling the drivers on the graphics card.
• I've tried a system restore to a period prior to the problem.
• I tried purchasing a cable that converts the VGA port to an HDMI connection at the monitor and that didn't help.

I'm somewhat proficient with computers and at a point where I don't know of any other solutions. I talked with somebody at Best Buy where I purchased the machine, and the suggested it could be faulty hardware. Given the number of people experiencing the same problem, I suspect that's not the case. Anybody have suggestions? Thank you very much in advance for your help.

Hi Sivaram,

Thank you for writing to Microsoft Community Forums.

1. Since when are you facing this issue?
   

This issue might be happening because of the faulty drivers. That’s the reason you are getting intermittent connection on external monitor.

However, you may try the below suggested steps.

Step 1: Try connecting on a different monitor and check if the issue still persists.

Step 2: Try using a different VGA cable to connect with external monitor and check the status of the issue.

Step 3: Update display driver adapters

You may refer the article
Update drivers in Windows 10 and check the status of the issue.

Step 4: Check for an updated Video driver on the

Acer drivers and Manuals page.

Hope it helps.

VGA signal

Hi,

For us to effectively assist you, we would be needing to clarify the situation first. Kindly provide the information we need below:

• Can you confirm if you have purchased a new monitor since your previous monitor is defective?
• Was the old monitor using VGA cable and the new one is only using HDMI?
• Have you tried using a different VGA/HDMI cable to connect to monitors?

Regards.
