Wireless HDMI problem

I am having an issue with my wireless HDMI to my projector. When viewing through Dish network receiver I have a full 1080 picture. When I switch to my computer for the display, the signal cuts in an out about every 2 seconds. I have just about tried everything I can think of. My PC has an onboard Intel HDMI out, I also have a GeForce gtx 1060 graphics card. I have updated drivers for both, used different cables and still have the same result. When I connect a smart TV as a display for the computer, it works perfectly. I have gone as far as using a VGA to HDMI adapter. This worked for awhile, but now it cuts out. My thoughts are the refresh rate needs to be below 60hz but the options I'm given for either outputs don't give me that option. I'm guessing the signal from the PC is in a format the wireless transmitter has a hard time recognizing, at least at the speed it is sending. Any thoughts?

You left out the make, model of the HDMI Wireless adapters.

I've seen this and since one worked and the other did not (HDMI wireless) I chalked it up to the HDMI wireless and not the PC. Some of them are iffy barely working devices.

Also, I've seen this when the projector was not really 1080p. Let's get the model numbers of the projector and HDMI Wireless system in this discussion next.

Additional information

The wireless HDMI is iogear GW3DHDKIT. Supposedly one of the top 5 for 2019. The projector is a WiMiUS P18. A direct connection to o the projector from the PC works perfectly. The HDMI transmitter and receiver are about 10 feet apart in direct sight of each other.

That only finds complaints about the Iogear unit.

But it does share what I have tried before.

Put your HDMI signal through a receiver as that would change how HDMI handshaking works. Also try some HDMI SPLITTER as that has been known to help.

I can not endorse or write which splitter to try. Example best seller cheap:

Try this.

A google does kick around where it fails with other sources. I'll try a tiny link in a reply next.

Answer
You are on right path

If the resolution and refresh rate is higher than usual TV, it's quite possible that's causing the cut out. The HDMI adapter may only support the standard 1080 with 60Hz refresh rate and cuts out when pushed above that. See if you can change the display settings to match that standard when you want to use the PC for this.
