Have you changed the HDMI drive in config.txt?

Had similar problems with a RPi 4B couple years ago.? It's HDMI output would work with some TVs and monitors, but not others.? Ended up buying a HDMI booster and that solved the problem.

Greetings,
I'm sure that the problem is the user (me) and not the RPI4.?
I just got a new RPI4 4GB and hooked it up to my 7-inch HDMI display and could get nothing but a black screen. I did the mod where you go in the micro SD card and go into the Config.txt file and changed the HDMI Mode to 16 and that did not work. Here is the link to the actual monitor that I am attempting to use:?
Out of curiosity, I unplugged the HDMI cable from the monitor and plugged it into my TV and it works great. I must have a setting wrong or something, if you know what I am doing wrong please help me.
Thank you
