Connecting my MSI laptop to my LG TV via HDMI has worked for months - now it's suddenly stopped working.

Hey, everyone. Grateful in advance for any advice you can offer.

Laptop

MSI GT72VR Dominator-063

NVIDIA GTX 1060, drivers updated

Windows 10, updated

Purchased in February 2017

TV

LG 49LJ5500

1080p

60hz

The Issue

For about 10 months, I HDMI'ed my laptop to this LG to play games on the big screen (and avoid an annoying color banding issue my laptop has). It worked flawlessly almost exclusively that whole time (once in a blue moon I wouldn't have any audio; unplugging and replugging the HDMI cable solved that).

Last Friday, I hooked everything up as I was about to start the Witcher 3. It worked and I saw my desktop on the TV. I got distracted by something and left it alone for a few minutes and when I came back, both the laptop and the TV had gone to sleep. No problem - I just woke my laptop up and turned the TV back on. Except this time, my desktop wasn't displaying; I got a 'no signal' error on the TV. It has now been a week and I've been unable to resolve this.

I did eventually make some progress, or at least a good discovery: when I connect the two devices now, the laptop will recognize the TV (I believe at the very start of this issue it wasn't doing this). It appears in the NVIDIA control panel, it appears as a sound output option, and I can select the different Windows project options and it definitely reflects each one I click (e.g., 'Extend' allows me to drag windows over to the second screen and I can see them enlarge once they pass a certain point. Of course, I can't see them on the TV).

Any thoughts? I'm pretty frustrated with it by this point. Thank you!

Troubleshooting I have attempted

• The LG still works with every other device - the Xbox One, the Switch, other laptops, etc. Every device works on every HDMI port on the TV and with every HDMI cable I own.
• The laptop recognizes and displays on another TV I own, a 720p I bought about five years ago. When I HDMI it to that TV, it works fine.
• I have tried other HDMI cables (which I know work) with my laptop on both HDMI ports the LG has (which I know work) to no avail.
• Here's something interesting. I thought trying the pass through feature with the Xbox One's HDMI in port would act as a less-than-ideal workaround/band-aid. When I try that, however, and go into the Xbox's settings to detect a device connected via HDMI in, it doesn't work. The Xbox won't recognize that anything's connected. The laptop will recognize the Xbox One by name. I connected the Switch to the Xbox One to try pass through and it worked instantly.
• I'd seen it recommended elsewhere to make sure the output display for the TV in the NVIDIA control panel is set to the correct one when connected. I've checked and it's set to the correct one by default (1920x1080, 60hz), but I still played around with those settings a bit just in case. Didn't change anything, sadly.
• I've set the TV as the main display in the NVIDIA control panel and tried all the different project options (duplicate, extend, 2nd only, etc.).
• I also saw on another forum someone solved this by changing the order they did things - TV off and laptop on -> plug HDMI into TV -> plug HDMI to laptop -> turn TV on -> voila. That didn't work for me. I've tried other orderings as well.

Troubleshooting methods I've yet to try/am going to try

• A clean install of the latest NVIDIA drivers.
• A factory reset of the LG.

THANK YOU to anyone who can offer any help!
