VIDEO CARD: INNO3d NVIDIA GEFORCE 7300GS GRAPHICS CARD (256Mb)
CPU: PENTIUM D915 2.8Ghz (dual core)
RAM: 2Gb DDR2 6400
MOTHERBOARD: ASUS P5W DH DELUXE DIGITAL HOME ATX
PRIMARY DISPLAY: SAMSUNG SYNCMASTER 205BW 20.1" TFT-LCD MONITOR (over
SECONDARY DISPLAY: STANDARD CRT TELEVISION (over S-Video)
HARD DRIVE: SAMSUNG SPINPOINT P120S (SP2504C) 250Gb SATA II
DVB-T TV CARD: PINNACLE PCTV DBV-T PRO TV TUNER
I record and playback freeview (Uk) digital television (DVB-T) using
the Pinnacle card.
I playback recorded Tv to a standard CRT television (as the secondary
display) over an S-Video cable from the Inno3d Graphics card.
What is the best display resolution setting for the CRT television for
best picture quality of a DVB-T broadcast? currently the graphics card
for this display is configured for "I/PAL" and the resolution is set
1024x768 (the other options are 960/600 or 800x600)?
Incidentally, the resolution for the Samsung TFT display (which I use
as the primary display, not for watching recorded Tv) is set for the
native resolution of 1680x1050.

Re: Optimum Display Resolution (to CRT Television over S-Video)
Freeview uses standard-def 576-line signals and so using higher
resolution than that will not improve picture quality. As such
you'll be best off driving the screen at 800x600 to save the
processor power and bandwidth needed to operate at a higher
resolution. If possible look for a 1:1 or pixel-to-pixel mode in
your software. That will result in a small border around the image
(or bars top and bottom if in widescreen) but will avoid the need
for scaling the image, which both harms quality and takes time.
