Using Laptop Screen As A Video Monitor

Success! I was able to install and use my old K-World PlusTV USB ($10 or so after rebate) with their Hypermedia software on my i7 using Win7 and I can now get full screen live video/audio from RF on my laptop screen. It's a shame that I can't do this with my Roxio USB capture dongle through composite video (RCA)... now I have to use a Coax and modulate the signal instead of straight from an analog camcorder. Come on Roxio, how about providing full screen video preview capability? It can't be all that hard, right?

I don't quite understand what you are asking.
You can only see the video in "full screen" after it is captured.

Problem is, there is a lot going on during capture and if you divert the CPU to producing a Full Screen image, you are bound to lose frames of capture while it is kept busy painting your screen
If anyone knows of any, please post your results.

I've a digital tuner/hard drive recorder here and I also tried using the capture device for full screen working (and it won't work).
You need a dedicated TV card with A/V inputs to actually grab the full screen video and all my older ones (Hauppage, Avermedia, etc) will NOT work in Windows 7 so the chances of the Hypermedia card working are extremely slim (all the TV capture cards from that era used basically the same decoder chip)

I tried another capture software I have and it doesn't do any more than about 60% of screen size...
I have an AverMedia capture card that will play full screen in my PC. But that is a $300 PCI Card which is not what you are after

I doubt you will even see what you are after from the Roxio USB Device, it requires so much more than you realize
As gi7omy pointed out, the computer CPU simply cannot keep up with this and it requires dedicated hardware to reduce its' load.
I capture and/or watch full screen HDMI (1980 X 1080) and I have a $300 card that handles the load. Even then there are glitches
