Projecting a slide show from computer to TV screen

Why does the picture immediately get very small on both the computer and the TV screen.

I’m using a HDMI cable to connect both.

MacBook Pro 13″, macOS 10.13

With no further information, I would guess the following:

Your TV has much higher screen resolution (maybe HD or 4K?) than your MBP, so the pixels in the slide show take up a smaller portion of it.

You probably chose to use screen mirroring with the MBP adjusting its resolution to conform to that of the TV, so they both show the slideshow small.

Try one of the following:

Use the TV as a second monitor, move the slideshow to the second monitor, and expand it to full screen.

Continue to use mirroring, but have the TV adjust its resolution to simulate that of the MBP.

I think those options were both possible back in macOS 10.13.
