HUD and elevation data are tiny when displayed on a TV

Running 7.0.9 (latest Fulgaz rev) on iphone 17 ios 26.6. I display Fulgaz on my TV by connecting the USB C on the iphone to the HDMI port on my TV. The older Fulgaz version correctly displayed large HUD and elevation graphs when I selected “large” in Fulgaz. Now, with the newer version, changing from large to small doesn’t result in HUD size displayed on the TV, and the HUD and elevation data is unreadable.
