Force the Mclassic to output 1440p with an EDID emulator!
If you have a TV, monitor, or Capture card that won’t show 1440p with the Mclassic (usually because the edid for these devices is set to 1440p 120hz which the Mclassic won’t see) you can use an affordable EDID emulator that will force the Mclassic to output 1440p 60hz.
