Why is Acer X115 image stretched when displaying widescreen DVD?
When playing a DVD encoded in anamorphic or 16:9 aspect ratio, you might need to adjust settings. If playing a 4:3 format DVD, change the format to 4:3 in the projector OSD. If the image is still stretched, adjust the aspect ratio and set the display format to 16:9 (wide) on your DVD player. For Letterbox (LBX) format DVDs, change the format to Letterbox (LBX) in the projector OSD.
