Windows 10: TV monitor as a second display

My laptop doesn't have an HDMI port but it does have VGA so I bought an HDMI to VGA cable to connect to a TV monitor for a second display. The TV detects the HDMI connection, but it just says "no signal" and my laptop doesn't recognize a second display in the normal sense. It recognizes itself as a second display and every time I try to use windows button+ P to extend the displays, the screen on my laptop changes to the "second" display and then I can't see anything or do anything and have to restart my laptop. The TV monitor continues to say "no signal" no matter what I do. I don't know how t

Second monitor (TV) is plugged in, detected by Windows, but no signal

Today I purchased a DP -> HDMI cable to hook up from my PC’s NVIDIA GEFORCE RTX 2060 Super to a Toshiba 50LF621U19 Amazon Fire TV. DP end in the graphics card, HDMI end on the side of the TV, and alas, no signal.

Windows still detects the TV and interprets that a second monitor is present - the mouse can move to the second unviewable screen and do what it wants, and be brought back to the main monitor. Display settings allow me to tweak all the settings for the TV
display but none of them make a signal appear.

Cable isn’t an issue - connects to other screens and displays them just fine. Computer shouldn’t be an issue either if it detects the TV and lets me configure the display that isn’t appearing. Computers have been able to connect to this TV just fine in the
past, but now this one is having issues.

I’ve snooped around quite a few threads on the internet and found little to help my case here. Any suggestions?

The main monitor is an ASUS VP249QGR, 1080p @ 144Hz by the way.
