If the OSD says HDMI IN when you plug it in then it should work. 

Yes it says that but no signal just a backlight on.

So it’s on a black screen? The source is 1080p 60hz or less?

Yes. Source is max 1080p 60Hz. The cables I used, work with The HDMI in of a previous M18X R2 with Windows 10 I had.

I was doing some research, it seems the SK9210-HS model is specific to the OG M14x. 

 

The SIL-SK63100 seems to be newer and has fcc listing for AW14/17/18 & M14x/M17x/M18x series. 

 

It's possible you have the older card?

I have the SIL-SK63100.

 

Waiting for the XWH200 to come and I'll test

I still don't understand if there's literally several different models with several different antennas or just 2 models and 2 antennas. 

 

For sure M14x uses a different antenna. 

 

Then there's the SIL-SK63100 vs SK9210-HS models.

 

M14x for sure uses SK9210-HS model but I am not sure what m18xR1, m17xr3, aw17, aw18, m18xr2 use. 

 

If they all use the same SIL-SK63100 model then what about antennas?

 

i found a m17xr4 antenna but no idea if it's the same for m17xr3. 

 

I also ordered the vizio receiver/transmitter pack on eBay but now need to figure out the DMC port cards. 

 

the part numbers I have for m17xr3 are different from the ones for the other models I found online but some listings show aw14/17/18/m18x/m17x all together
