I'm trying to stream some nintendo switch gameplay. I have an hdmi splitter so I can send video to the capture card and to a monitor. When I plug both in, the monitor suddenly has a bunch of blue and green horizontal lines all over the screen. If I unplug the hdmi cord going to the capture card, the video looks fine again. I only have problems when the splitter is connected. Is it just a cheap splitter? I've had similar looking issues when using an hdmi auto switcher. Please help
