Older 21" CRT and HDTV Video Problem (blurring of high-speed motion)

[nocona_xeon]

I am still running a very nice (yet quite old, yes) 21" CRT in the 1600x1200x85Hz mode and 32bit color depth.

Here is the question: If HDTV from my OTA ATSC capture card can only be outputted at 60 interlaced FPS when in full screen mode, is that what is causing the noticeable "blurring" of athletes during high speed movements/motions because the monitor is not synced-up to that output rate (ie the monitor at 85Hz versus the WinTV software window at 60Hz)?

I am using the mobo's onboard Intel GMA X4500XD chip with WinVistaUltimate64, best drivers, and the CPU usage of WinTV is extremely low, at around 6%, likely due to WinTV interacting with the X4500HD chip efficiently.

Or, is something else causing the image to appear smeared? Like "poor HDTV encoding on the part of the EPL soccer broadcast?"

I have seen not just the regular HDTV's but even 4K HDTV's now advertised as running at 240Hz which is supposed to eliminate all blurring (or is that some hardware/software interpolation of frames magic?). I wouldn't really know because I don't watch movies at all on a large cinema HDTV meant for non-computer-use (ie meant for home theater use) because I have no interest. A small window of a sporting event while working is nice though and switching it to full screen after a goal is even better.

Just seeking some help on this one. Thank you.

You've hit most of the high- (low-?) lights ... you may be able to help your cause a bit by dropping your monitor refresh rate to 60Hz when watching TV.

The difference in aspect ratios certainly impacts image quality as does the GMA X4500 post processing for video quality... and WinTV is just not that good with no support for 3rd party encoders.
