Windows 10: HDMI port suddenly stops working

My HDMI port has suddenly stopped working... it was working till yesterday, in the morning when I tried connecting another monitor, it's not getting detected... the same monitor and the same cables work fine in my friend's laptop so that means the cable aren't loose or anything... I also tried MSDT troubleshooter which asked me to restart my laptop, did it, still the port wasn't detecting the other monitor.... again ran the troubleshooter and was again asked to restart...

HDMI Port Stopped Working

I generally use a second monitor via an HDMI cable while working. However, it stopped working today.

I checked these:

• Windows cannot detect a second monitor when HDMI cable is connected to the second monitor.
• HDMI cable which I use works if another device is connected to the second monitor.
• My computer detects my HDMI-to-VGA converter through HDMI port.

My computer runs Windows 10 Home with latest updates installed.

I suspect this is due to a driver error. How can I fix this problem?

 

External monitor stopped working suddenly

I have been using an external monitor with my Lenovo laptop. Today it suddenly stopped working. I have tried the following:

- connected the monitor and the laptop with an HDMI cable (does not work)

- connected the monitor to docking station, which is connected to the laptop (does not work)

- connected another laptop to the docking station (works)

- connected another laptop to the monitor using HDMI (works)

Obviously, the probelm is not cable or the monitor (or the HDMI port on the non working laptop since it doesn't work with the docking station either).

I have tried restarting the laptop, removing the driver, updating the driver, rolling it back. Nothing has worked.

Any suggestions?

 

GTX 1650 HDMI Ports Not Working!?

Comments noted, thanks. The video cable came in a packet labelled HDMI to VGA, so this cable should work. When using this video cable as a test with my newer monitor, again there was no signal seen on the monitor. To me that suggests a problem with the cable. The VGA input port on the old Philips monitor does work when a VGA to VGA video cable is connected to an older computer that has a VGA output. So that suggests the VGA port on the old Philips monitor is working, and again suggests a problem with the HDMI to VGA video cable. I don't have another HDMI to whatever video cable to test the video card HDMI ports. Although it is possible that the GTX 1650 HDMI ports could be faulty, I still suspect that it is the new HDMI to VGA video cable that is faulty. My intention is to return this new HDMI to VGA video cable to the store where I purchased it from, and maybe get them to test the cable, and/or get a refund. This store does not at present have DVI to VGA video cables to exchange with. Ideally I should get a DVI to VGA cable to run from the GTX 1650 video card to the old monitor. There is no option to purchase another monitor at present due to limited finances, so the cheapest and preferable option is to get a suitable video cable that works with the GTX 1650 video card and with the old monitor.
