1st Gen. Sony SXRD?

[1BAD3V]

I was at a local Best Buy looking at the Sony BDP-S1 when an employee walked up and asked if i had any questions. I asked if he had any Sony BD players and he said he had 2 left. He then asked me what TV I had. I told him 50" Sony SXRD (not sure of the model #). I told him that the speakers were on the side and then he said oh that is a 1st Gen model. He then said that it'll display 1080p but won't display 1080p through any input including HDMI. Is there any truth to what he told me?
