1/4 size in composition monitor

[ricoca]

On all other computers Arena sets up showing the clip filling both the Preview and the Composition monitors . Not so on m1 chip iMac .., I have faffed around and cannot figure out how to fix this ...i.e. I want the clip to fill the said monitors as on the other computers ..[ both Windows and Mac ] ??? any ideas anyone ???

discovered that its caused by having an external monitor connected [ in this case via HDMI dont know if it does it with any other connection ] any reason why it should do this ?

Could you share some screenshots of what's going on?

however I configure the display on the M1 iMac settings this situ remains . Even if I set the settings the same as on the MacBook Pro ...?

Try resizing the Resolume window, that should update the layout and preview sizing.

this , see pics , seems to solve the problem .. although only if u extend the displays .. if u try and mirror the displays we get the 1/4 comp/pre monitors .. which is no great prob really as u why would u actually want a mirrored resolume ???
