The specs say up to 2 external 6K@60Hz displays are supported, but doesn’t say how many 4K@60Hz monitors are supported.

Can it support up to 4 external 4K displays at 60Hz?

Up to two external displays with up to 6K resolution at 60Hz at over a billion colors (M1 Pro) or
Up to three external displays with up to 6K resolution and one external display with up to 4K resolution at 60Hz at over a billion colors (M1 Max)

Hi,

My question was about multiple 4K displays, not a combination of 4K and 6K displays as it is mentioned in the tech specs.

In other words, the tech specs don’t say how many 4K (and only 4K) monitors can be connected to the M1 Pro version version (nor the Max version).

Thanks.

anything whose horizontal and vertical resolution is equal or smaller than 6K can be supported very easily in almost the same way as 6K.

or simply read the specs as "6K (or smaller)".

HDMI port is limited to 4K max.

I gave it a google and indeed I cannot find tech specs for only 4K displays
