Random blurry question

Hi, i have a random question that just hit me. Whenever I watch streaming video, even in 600k-800k quality (so reasonable for streaming) and also when I watch tv with my usb2 tv card (a nebula digitv) the video is blurry.

Its only really noticeable when watching sport such as soccer or hockey when the ball/puck is being moved around quickly. Its not a big problem, when i sit far back its hardly noticeable (i mean you dont sit 6" away from your tv so!) but its still more blurry than regular tv. Is it just because tv's are generally less blurry? I couldnt say whether it happens in dvd's or not because as i say its only noticeable watching sport.

My monitor is a samsung 225bw
# Screen Size: 22 inches
# Aspect Ratio: 16:10 (Standard PC Widescreen)
# Resolution: 1680x1050 (60hz)
# Colors: 16.7 Million
# Brightness: 280cd/m2
# Contrast Ratio: 700:1
# Response Time: 5ms
# Viewing Angle: 160°/160° (CR>5)
# Inputs: Analog RGB,DVI Digital Link (with HDCP support)

Graphics card is a geforce 7900 GS.

Maybe just the screen being 60hz?

Not a problem just a curiosity, cheers
 
Whenever you has different types of signals passing through your computer to be viewed, they have to be adjusted to your output device. For example, a normal old fashoned American TV signal runs at 720x480 with a 0.9:1 pixel ratio and a refresh rate around 29.9 or 23.9 (depending on the equipment used to record and broadcast it), while your PC uses a 1:1 pixel ratio at the res of your choice, and refresh of your choice (usually 60).

Any time the signal is altered for display, it will lose quality and seem either blurry or blocky, depending on how it is resized. Besides all that, you also have to consider compression formats, compression rates, decoder quality, decoder filters, fixed and variable frame rates, and stuff like that.
 
No the 60hz wouldn't have anything to do with it. Thats about standard for LCD. I have a Samsung 22" 226BW myself and haven't noticed any blurs using my native resolution of 1680x1050@60Hz either.

Are you using the Samsung driver or the default Plug and Play Monitor driver?
 
thanks for the response that makes a lot of sense. I was using the pnp driver but have installed the samsung one, i'll let you know if i see a difference
