Cannot get Intensity Pro 4K to work

Hi. I've looked through all the posts here, and I've looked through the manual numerous times, but for the life of me I can't get my IP 4K to work!!! I've downloaded the drivers, made sure the versions match, everything is seated properly in my PCIe slot. The monitor works, the output device (Nintendo Switch) works just fine, but no matter what settings I put things on, I can't get it to output video. I'm pulling my hair out!!! I've even tried swapping the HDMI cables with different ones, and all of them are known to work just fine. Plug in Switch dock into a TV and it's golden. The auto updater is enabled and all the startup things are active.

Hi Collin,
Seems you missed some helpful threads here (it is easy to get overwhelmed by the sheer amount).

To make it clear: neither do I have a IP4K nor a Nintendo Switch. So I just can give advice from what I found while looking up your problem on the internet.

It seems the Switch got a problem with EDID handshake. That's when two devices talk about their capabilities and change to the best common settings for video signal transfer.

There are several standards and if they do not match you get no signal. Unfortunately I haven't found the specifics of the Nintendo Switch capabilities.
There are two standards for the framerate in NTSC: 1080p60Hz and 1080p59.94Hz
And there are two different color spaces: YUV and RGB

The IP4K does support all of those.

Set the IP4K to 1080p60 for INPUT and OUTPUT.
Make sure you are plugging the Nintendo Switch to the INPUT of the capture card.

Try connecting in this order:
Has to be done in this order (start with nothing plugged into the dock)
Plug in USB-C power adapter.
Plug in HDMI to Dock.
Plug in HDMI to TV.
Put Switch in the Dock.
Turn on TV and select input.

If that does not give a signal, try the same again with IP4K set to 1080p59.94 for IN and OUT

If that does not work, your best bet might be an external HDMI splitter with EDID management, like it had been recommended in this thread:

An alternative splitter has been tested here:

Thanks for the reply. I can get the Nintendo Switch to display on any TV and on the monitor by itself, but when I'm trying to use the IP4K, all I get is a black screen.

So you have tried everything I suggested to try?

Aside from purchasing a splitter, yes.

Then the splitter is your best bet.
