Exron DSC 301 HD and custom resolution C3 preset!!

[Kiki2024]

Hi everyone!!

Thank you for the great forum as always very helpful
I have an extron DSC 301 HD (more than one actually) all updated to the latest firmware version. I have (in all of them) same issue...i can upload custom edid (i can do it by assign the single edid after imported bin file through CRU into the edid page on the pcs sodtware...very not intuitive) but only C1 and 2 while C3 cant do it in any way!!still same 720p default one. I remember on DSC hd extron that i have i had no issue at all and could put all 3 preset (as always not intuitive at all, like put the edid each time same assignment and the scaler will rotate the save of the edid) but on the 301 it seems impossible.

Any of you tried with success?
