This is why I had hoped purchasing a $25 tiny, prebuilt, dedicated 60Hz >120Hz frame converter board originally intended as a replacement part for a larger LCD TV might work as, not only is it small and extremely light but it even runs off the same battery power as my portable LCD gaming monitor (5V@3A)...but, while you never said it wouldn't work, you did say "to forget about it". Before I give up on the idea and move in another direction, could you confirm that you have reason to believe these boards just can't be repurposed in this way. I'm getting ready to return the screen before the 30 days is up if I know it won't be successful.
Before I tell you to give up, can you tell me if you found a Chinese supplier willing to sell them directly to you separately of a television manufacturer? The supply chain tends to be too integrated, like an unusually-shaped car part that cannot be adaptored to work properly with off-the-shelf screens.
It often are integrated TCON board that has integrated LVDS connectors only compatible with specific panels, e.g. AUO versus Innolux screens. If you know someone who can adaptor LVDS to DisplayPort, and add a battery supply, it probably could be Rube Goldberg'd, but might eat more power than the portable screen does. The problem is these are very specialized parts not currently easily obtained (supplier difficulty) and not easily adaptored (compatibility difficulty). The miniDP scalers are more often found in laptops which don't use interpolators, so you're stuck with HDTV connectors like LDVS panel ribbon connectors.
What resources do you have? What research have you already done? Any requisite display engineering skills on your team?

I have a WiFi 6 router and I like the idea of streaming over that but, worried about the range. I need 200-300ft from the router (no walls)
200-300ft is not close enough for low-latency WiFi unless you use special antenna-to-antenna hop to a 2nd WiFi 6 router. If you don't mind setup time, build a crashcart or suitcase with the equipment, and set up the antenna-to-antenna hop, to the WiFi 6 router that's closer to the action (users of 120Hz streamers).
For Distant WiFi: You Will Need A Low-Latency Bridge To Your WiFi
Can you at least hopper the remote WiFi some way (Ethernet, optical, Laser wireless link, WiFi bridge + directional antenna, etc) to a second closer WiFi 6 router dedicated to being closer to the 120 Hz screens? There are many options that will meet your latency budget, while bringing a (second) WiFi 6 router closer to the "action".

and while I had considered the iPad for it's beautiful 120Hz 12.9" screen, I need to give the viewer a wider, more immersive FOV and 17.3" is barely wide enough while still being light at under 2lbs.
Left Field Idea #1:
The Oculus Quest or Quest 2 Cordless Low-Persistence VR Option
The other option is using Oculus Quest as cordless immersive streamers. Be noted that strobed 60Hz and 72Hz has less motion blur than nonstrobed 120Hz. Remember that strobing can reproduce the HFR-like experience for framerate=Hz motion for fast-camera-shutter material. I can turn an many LCDs into a CRT-motion-clarity at lower refresh rates than 120Hz, e.g. 72Hz, 75Hz or 85Hz strobing like a CRT. There can be sufficient immersion feel since the Quest headsets is like strapping an IMAX cinema screen to the eyes.
You can use software such as BigScreen to put a virtual movie theater in 6dof VR. You can even stare downwards and see a virtual folding theater seat, and then stare upwards, and see an IMAX screen, in a virtual 3D-rendered movie theatre. This is not crappy Google Cardboard, but full 6dof CRT-clarity low-persistence virtual reality. Although there is the Facebook requirement, if that is acceptable, this can double as immersive cordless streamers too.
Left Field Idea #2:
Consider Tiny Batteries With AC Power Outlets Too For Easier Portable Tech...
It may be easier to jerry-rig something with those because the connectors are compatible (
AC outlet on the pocket battery!), rather than having to deal with things like trying to adaptor LVDS-to-DisplayPort and all the headaches. You can also buy cellphone battery banks with built-in AC outlets nowadays (Ravpower sells them, I have one here), that fits in your pocket, that can power any 240Hz gaming monitor for approximately 1 hour. Semi-related, but new lithium batteries are quite big-output nowadays, I also recently have
successfully boosted a car with a tiny cellphone charger, which I have too. It's quite tiny, barely bigger than two decks of playing cards side-by-side, but with help of its capacitor-boost, it outputs up to 1000 cold cranking amps (12 kilowatt surge) for starting a dead car. That's a jawdropping amount of power in a tiny thing now.
And if you need something even bigger, don't underestimate the power of a modern
1000-watt Jackery Power Station, which can now successfully battery-power an RTX 3080 gaming tower AND battery-power a 5000-lumen 120Hz DLP projector connected to it, shining onto a big inflatable screen at 120Hz, with no AC outlet nearby! In the middle of nowhere at a campground! That new 1000-watt camping lithium battery is lighter and smaller than an old-fashioned lead acid car battery; you can even run space heaters. These are amazing camping power supplies, it even got the rare 5 star Amazon rating (not even 4.5 stars).
You can get power banks with 120V AC power outlets from as tiny as pocket size 65watt-hour to lunchbox sized >1000watt-hour, including intermediate laptop carrying-bag sizes.
These neat gadgets weren't around 5 years ago, it is all thanks to Tesla commoditizing the boom of lithium batteries with high power output sufficient for duty never formerly dreamed of a couple decades ago.
Possible jerryrigs:
- Inflatable screen and a bright projector
- Bring the streaming computer out in a cart/suitcase containing a Jackery battery, and put the WiFi 6 router on top of the cart
- Battery power small 32-inch HDTVs with built-in 120fps interpolators
- Battery power some used 23.5-inch "PlayStation 240Hz 3D Gaming Displays" (fake 240Hz, but that's interpolation)
- Etc.
