GH4 + Leadstar (or unbranded) Portable TV Monitor

Anyone have luck with these? It's the portable TV that appears to be listed in multiple ways.

I just bought one for the heck of it. Needed something larger than an on camera monitor that we could use in our small video village. But the image is stretched vertically, subtle but noticeable. No matter what aspect ratio I put it on, it's stretched. Auto, 16:9, Panoramic, Point-to-Point all result in a vertically stretched images. 4:3 squeezes the image horizontally. Zoom1 and Zoom2 both punch into the image but it's still stretched.

The output of my GH4 doesn't look like this on the SmallHD or on my LG TV. But I've tried C4K and UHD modes of 4K. I've tried 1080p. All of those GH4 settings result in a stretched image. So it must be the TV... right? Maybe someone knows something I don't and can help me - worth a shot.

Thank you!
