NVidia GTX 970 Not Recognizing HDTV via HDMI Connector

So my new GTX has been working like a charm. EXCEPT whereas my old Radeon 7850 could detect my HDTV no problem via an HDMI cable and the CCC "Detect monitors" button, the NVidia control center, even with "rigorously search for TVs" on, is not finding it.
Feels like there isn't a ton to do here. All the stuff I'm finding on lesser forums is pretty useless.
Card: NVidia GTX 970
Drivers: All brand-new.
TV: Samsung
HDMI Cable: 100% functional with other computers. 30 feet, strung into the living room.
Any ideas about how I could resolve this? There's a "PC" connection on my TV, but it's a serial port, and I don't have a 30 foot serial cable with which to connect.
I didn't run down every possibility because my girlfriend and I decided to just play a game with the monitor, but I want couch co-op to be viable again!

I hate to even ask this because it's probably too basic and you've probably already done it...buuuuuuut, have you made sure you were using the correct input mode (HDMI1, HDMI2, etc...) on your TV before you tried rigorously searching for TVs?
But, nope. TV is on HDMI 1, cable is plugged into HDMI 1. The only options on the TV not grayed out are TV, HDMI 1, and PC. PC doesn't have anything attached.
Sony KDL-40s5100.
At the moment the NVidia control panel only recognizes one display, the monitor plugged into the serial port. It doesn't find the TV display. Same deal with the Windows control panel, only detects the Acer display.
I didn't see mention of it, but have you ascertained that it's not a bad cable? That's what it sounds like, a lot of older HDMI cables, at long lengths, are less than perfect.
I'm assuming he means VGA? i've seen more than a few people over the years call VGA serial and vice versa.
Oldy-style port that comes up twice a year when I connect a monitor, not oldy-style port that comes up twice a year when I need to use the keyboard in the BIOS.
Edit: Cable's fine, works with the laptop.
This is my guess. Most (all high end) video cards don't ship with VGA. Willing to be the OP has the monitor plugged into the motherboard graphics, which is then disabling the discrete GPU, which is why the HDMI out on that isn't working.
All of the video sources need to be coming from the graphics card.
Alternatively, the cable that's plugged into the monitor, are the ends white or blue?
