Testing SD 480p

Model : 3050x - Roku 2XD
Software 8.1.0 Build 4131-02

I need to test our application in true 4x3 , is there a way to force the Roku to use 4x3 ? Or is this limited to what the Roku supports ?

The only options available under Roku settings displayType are 720p and 1080p.

Gotta buy a Roku Express+ and use the RCA connector to an old-school TV, then you’ll get the option.

Roku 2 XD has composite output, if i remember?
Yank the HDMI and connect composite cable, that way will get SD option
