pc doesnt detect second monitor (tv)

I have updated my drivers and done everything i could find on the internet to solve this problem. My pc is not detecting any kind of second monitor. When i go to device manager and press and expand display adapters it also doesnt show my second monitor. I have to say my second monitor im trying to use is a Tv but ive used it before as a second screen on my laptop. How do i fix this for my pc?

 

Windows 10 can't detect my second monitor

Thank you for confirming. We can do the following:

When the second monitor is not detected, we need to isolate if it's the monitor, the cable connecting them, or the port. We suggest that you remove your 1st monitor, then use the 2nd monitor as your 1st monitor. After that, connect the 1st monitor as the
2nd monitor.

Usually, this it's driver-related. Windows 10 won't be able to detect the 2nd monitor if the monitor driver is out of date or faulty. We recommend, rolling back to the previous installed graphics driver and monitor driver if it updated. Otherwise, update your
graphics and monitor drivers on the Device Manager. To do so, follow the steps below:

• Type Device Manager in the Cortana search bar and press Enter.
• When the Device Manager window appears, click the Display adapters and right-click the item below.
• Select Properties, then Driver tab, and click Roll Back Driver and follow the on-screen instructions.
• Expand the Monitors, then right-click the second monitor and select Properties.
• Click the Driver tab, and click Roll Back Driver and follow the on-screen instructions.

If the issue persists, update the drivers. You can manually update the driver by visiting the websites of your graphics card and monitor manufacturers to get the fully compatible drivers for Windows 10. You can run the Find
and fix problems with devices and hardware to automatically check for driver updates. Additionally, we'd like to know the make and model of your graphics cards and monitor?

Post back anytime at your convenience.
