On a Raspberry Pi 4 with no GUI, I have two monitors connected and I have a video playing using omxplayer on screen 0 (display 2) and just the login screen on the second monitor. All screenshots are from HDMI0, I can't get one from the second screen. I tried the following commands...

/usr/bin/raspi2png -D 1 --pngname /unit/hdmi1_screenshot.png /usr/bin/raspi2png -D 2 --pngname /unit/hdmi1_screenshot.png /usr/bin/raspi2png -D 7 --pngname /unit/hdmi1_screenshot.png

My mistake. This binary is awesome. This seems to work....

/usr/bin/raspi2png --display 7 --pngname /unit/hdmi1_screenshot.png
