FireTV and large display issues

I’ve been trying for a while now to get a full screen calendar card working with a few extras on a 32" tv hooked up to a fire stick. The closest I’ve come is the grid view which sometimes works, but only with the native browser in “desktop” mode. It seems like it’s not detecting the display at the size that it is and then shrinks the content to a single column. I’ve tried Fully Kiosk and WallPanel without good success. What I’ve noticed is that if I change the theme, I can see a rectangle in the background and it looks like it thinks my cards expand well past where it thinks it should. If that makes sense. Thanks all!
