Trying to get a wireless HDMI adapter working

More of a general Linux question but it's probably been a decade since I logged into any of my old Linux forums lol. 
My CNC machine is on wheels and my monitor sits on top of a file cabinet next to it. I broke my last monitor absentmindedly pulling the machine out to work on it and have almost done the same with my new monitor. 
My new monitor has HDMI or VGA. 
My computer internal GPU only has displayport. 

I bought an HDMI wireless adapter I would love to try to get working but it hasn't gone so well so far. 
I plugged it into my displayport to HDMI adapter cable but the internal GPU doesn't seem to see it and won't send signal to it. 
I bought an active displayport to HDMI adapter hoping that would fix it but no luck. 
I also have an old quadro 600 card that has a displayport and DVI. I haven't tried a DVI to HDMI yet. I might have an adapter laying around somewhere. 
With the HDMI wireless adapter plugged into the quadro with the active displayport to HDMI adapter it displays the boot manager to boot up but deactivates before it gets to the login screen. 

Now I'm trying to figure out the best way to move forward. I think I could probably figure it out on my own but I think it could take hours more. Possible options I think might be worth persuing. 


1. It seems like there is a way to force a signal to be sent to a displayport but it seems like the displayport still needs to detect something being there before it registers as a device to have that command work? 

2. The built in displayport doesn't display anything on startup with the HDMI wireless adapter into the displayport adapter, into the computer. 
The quadro card does but goes off before the login screen. 
Maybe it would work to force the signal to this port instead?
A semi related topic I found online suggested installing the Nvidia drivers. This is getting into a much bigger box of worms than I had hoped for my little Linux machine but if this would likely solve the problem I would do it. 

3. I think I can find a cheap graphics card online with an HDMI port. If this would be a better option and work out of the box, even just if it saved me needing to mess with installing proprietary drivers or anything I would be open to that as long as I was confident it would work. But if it puts me in the same situation as I have with the Quadro then I might as well just go with that. 

4. if there is an option, a wireless adapter, or anything else that would work better than anyone knows of let me know. 
If it's any help this is the one I currently have.

It doesn't look like displayport wireless transmitters are really a thing which is kind of interesting. 

 

To late but would have been better and probably cheaper to get DP-HDMI cable with more length, higher quality one should be 20-30$.
Do not install NVIDIA drivers on a machine PC with RT kernel, it does not work to be happy with it, and sometimes at all.
Now some better news, boot with the add on graphic, wait for it to go blank, wait a bit more, after roughly 2-3 minutes press and hold CTRL+ALT and press several times backspace, this should reset the X server and maybe, just maybe switch to working monitor.
Tip 2: connect another monitor to VGA port, boot Linux, go to prefernces and screen or monitors or displays, there chose and turn on the monitor on WiFi link, apply. If it works, reboot to check if the settings stick.
Tip 3: power on the PC with a working monitor, press or beat the right SHIFT key till you get the GRUB menu, hit E, use arrows to go to line containing "quiet splash" or similar and add after it "nomodeset", press F10 to boot, connect the WiFi monitor and disconnect the working one, wait for it to boot.
If any of those do not work, probably the WiFi dongle does not comply with HDMI standard communication, as i doubt the DP-HDMI adapter is not working, although i have seen DP-HDMI cables failing miserably to work on some PC's while worked fine on some other PC's.

For what it's worth, did you try to connect USB power to both adapters? They appear to have a 'charger port' in the side. I think HDMI can supply some power but it seems quite limited.

A longer cable was definitely my first thought but it's still one more thing to trip over and need to remember any time I move the machine or anything.

Thanks for the heads up about the Nvidia driver. Glad I didn't try it.

The wireless setup does display the GRUB menu when plugged into the quadro card, just not when plugged into the Optiplex 9020 (or whatever it is) internal graphics port.
I'll try the "nomodeset" test.

If that doesn't work I'm still torn on whether it would be worth getting a cheap GPU with HDMI to try.

I am also considering trying to attach a smaller monitor to my machine. At the time a bigger monitor separate made sense but maybe I could find a way to attach an arm and a 12-15 ish inch monitor in a way that wasn't too obnoxious.

Of course then that gets me wondering.
Is there any sub $100ish touchscreen in that size range that would have 1920x1080 for Probe Basic that would be relatively plug and play?

Yeah I got it casting with the quadro card installed and plugged into that card it does work up to the GRUB menu then turns off during boot.

Look for Asus ZenScreen , usually over 100$ but often under on sale.
For some reason, 15.6" are cheaper than 14" !
Also, get the IPS version, not the TN or VA versions.
