Can't get 1020p on HDTV from Bose V20

[biswasg]

I recently set up a Home theatre system
Bose V20
Sony KDL-W4000 full HD capable of 1020p connected with the V20 with the HDMI and optical audio cable
Sony RDR=HX980 DVD recorder.

As both the RDR-HX980 and the Bose V20 advertise to upscale video signals to the highest resolution supported by the TV, I assume the Bose V20 should upscale to 1020p. However, when I play a DVD it shows 720p. I have gone through all the settings but can't figure out why I can't get 1020p resolution.

Have you gone to the settings menu and set it to 1080P? Also, be sure to check your source resolution...
