Hello, from a arduino point is there a way to get an LCD monitor information such as the make and model, screen resolution? I know on a desktop pc it knows the make and model same with hat screen resolution it can go up to.
Edit: I’m not trying to display anything on the display. Only trying to get the information from the monitor that have i2c or something that can identify it.

If you look at the library .h file, you can see if there are any methods for that. I doubt it, though.
What exactly do you mean by an LCD monitor in the context of your question ?
@UKHeliBob computer LCD monitors can tell a pc the make and model as well the screen resolution size.
If on hdmi it has i2c. I haven’t tried it yet but I’m going to try to see if there is a i2c address then trying to figure out how to read whatever is on the i2c.
It knows that only for USB connected devices. That is the initial part of the data exchange when the device is plugged in. A device driver is called that is supplied by the manufacturer and that driver supplies the data for that model of device.
@sonofcy I know I’m the i2c library I can do a read. However I can do a read and write from one arduino to another but I don’t know how to read it it from something like a pc monitor.
@Paul_KD7HB Not through USB’s I’m speaking of HDMI or vga.
Exactly the same communication steps for all devices. The factory driver supplies the information.
@Paul_KD7HB That is what I’m trying to do. But I have no clue in arduino how to do that.
Do you have a factory driver program for your Arduino?
You did not answer my question but from your reply and others in the topic I assume that you are trying to get that information from a PC LCD monitor using an Arduino
Is that correct ?
@Paul_KD7HB Noo. Don’t know what that is or how to get something like that if its possible?
I guess you will have to contact the company that built/designed the device and see if they will help.
Give an example of one Arduino interrogating another Arduino for I.C. type, RAM size, manufacturer.
I have never heard of such a thing, but maybe.
@xfpd There is none. That is what I’m trying to do.
@sonofcy me either. I’m just trying to get the information off the monitor like what the computers can do when a monitor is connected to it.
@Paul_KD7HB not going to happen.
You wrote that you already know how to do this... here
@xfpd No I wrote I can send and receive data from one arduino to another through i2c. I did not say I can read information from the monitor to arduino. Which is what I’m trying do.
