Different between TV screen and PC monitor

[GangstaRap]

for some of you it might seems like a stupid question i guess...
but there's something i don't get and i'll be very grateful if someone can shed some light for me.

I have Peerless TV (4:3 PAL broadcast) and it doesn't support HD video/broadcast,
it can only play the "sane" resolutions (STV)...

my question is - how come my PC monitor (20' SAMSUNG 206BW) can display any
resolution i want - even the most highest and yet - the TV screen cannot display
video above 720 width?
what does the PC has that the TV hasn't?
is it the graphic card?
or maybe it has nothing to do with PC hardware and it's all about screens limitations?

Thanks in advanced!

TVs, being based on 1940's broadcast technologies, are designed only to show television signals of very specific characteristics. Computer monitors, using much more modern technology, are designed to be much more flexible because computers can output a wide range of resolutions and refresh rates.

so it's nothing else then appliances limitations...

does CRTs PC monitors can display HD video too?
what if i'll get a TV card for my PC, would i be able to watch HD broadcasts? (when it will be available in Israel)

It will depend on the monitor. CRT monitors usually only accept DVI or VGA as inputs. HD players, satellite and cable boxes typically only support HDMI or component for HD output. HDCP free sources may play via an HDMI->DVI cable.

I don't know what the case is/will be in Israel. In the USA over the air broadcasts must be unencrypted so any TV cards with an ATSC tuner can display those sources. Cable TV is supposted to transmit local OTA sources unencrypted but cable uses QAM encoding rather that ATSC. So you need a card with a QAM tuner. But even with that only a handful of channels are unencrypted.

Blu-ray is AACS encrypted and requires HDCP support by the graphics card and monitor. Without HDCP you won't get high definition (there may be some exceptions to this).

You will likely be better off getting an HDTV that supports computer input via VGA or DVI/HDMI. I have a Nvidia 8600GT graphics card and Samsung LNT-4665 HDTV hooked up via a DVI->HDMI cable.
