By panel, are we talking the screen or the electronics board??
The screen is probably compatible with a range of other models, and even brands.
The electronics might be compatible with a small range of equivalent models from other brands, and will physically fit other models in the same series from Acer.
You would have to take your existing monitor apart, make a note of the part IDs and research who makes them; you will often find they make the same part for multiple brands.
