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

Yes I use the KVR0Y antenna, it's for M17X R4 and it fits in the backside of the top lid.

 

So this is strange the M17X R4 and the 17 R1 are using the same DMC card.

 

But they are using different mux switches.

 

M17X uses a DP MUX: DP to DP to send the output to the DMC. The same MUX it uses to drive the eDP signal.

 

Meanwhile the 17 R1 uses a HDMI MUX: HDMI to HDMI then to a HDMI Redriver and finally sending the output to the DMC.

 

Does the SIL-SK63100 chip interpret the video input as DP++? I think that's what it does. So it means the RTX 3080 I installed can work with the WirelessHD in DP_A

It means as long as I order the correct antenna board and cable, the wihd card should also work in M17xR3 then. 

 

Someone told me the DMC cards are limited to iGPU but if it's wired through MUX it should work with dGPU.

 

I'm still trying to figure out all the parts. hard to find proper info and a place where I can get all the parts in US
