Probably not, if you need all 80 images visible at once and some contain text. A 1080p TV is 1920×1080 pixels total—about 2 megapixels. In an 80-image layout such as 10 across by 8 down, each photo would only get about 192×135 pixels. That is very small, so fine detail will be limited and text is unlikely to be readable.

If the goal is just to display many images attractively, a simple option on a Mac is the Mosaic screen saver, which can show photos in a grid and cycle through them. But for a static 80-photo board where each image needs detail or readable text, a single 1080p screen is not a good fit. You would need either fewer images on screen at once, larger individual images, or a higher-resolution display.
