Yes, the set itself has two tuners so it can have the PIP feature.
When you hookup your unspecified PC you have introduced an entire host of possible problems. Though Macs are generally considered more a piece of cake than generic PCs as Apple has included user friendly software to do so.
The TV has the dual view capability, but evidently your PC does not. Perhaps you must have the PC doing either the TV picture or PC controlled blank screen, but not both.
I'm not the one up to this, but specify more detail.
I'm trying to set up PIP on my tv, Hitachi 50VG825 rear projection. The TV has a dual tuner so it can do the PIP on it's own via the various inputs and cable/air connections however it's not working the way I would think it should be. I'm hooking up my laptop (via a s-video cable out of the laptop converted to an RCA connection and then connected to the TV and it seems to work fine except when I try to do the PIP to watch the cable on one window and in the other surf the web. The coax is coming into the HD STB and then out via the HDMI connection. Anyone have any insight on why the PIP isn't working the way I'm expecting it to? I've looked into the manual to see what it said about PIP but it was a bit confusing. It said the following:
This Two Tuner feature allows you to view antenna inputs on both the main and sub picture simultaneously, with separate tuning control for each. When a Digital channel is viewed in the main picture the Digital channel can not be viewed in the sub picture. And when the Analog channel input is viewed in the main picture, the Analog channel input can not be viewed in the sub picture.
Can someone clear this up for me???? Especially since I'm using the HDMI instead of a standard RCA connection I'm pretty confused.
