Unhappy Consumer Electronics vs Computer Display

here are a few thinks about display quality that I've always been confused about:

1. Why do most of the times DVDs look better (brighter/cleaner) playing with a consumer dvd players on a television then on a PC using computer hardware & software? Monitors have so much higher resoltion support than standard TVs. I aint talking about HDTVs or anything!

2. Consoles (XBOX/PS2) have so less resolution than computer games, why do they look so good on Television? If we use a game in console res and play it in PC, the low vidoe quality is so EASILY noticble!!!

Because you don't sit on the other side of the room with a pc, and also pc displays show much more, like you said they are higbher resolution and their refresh rate is higher, so you see more of the same image than is displayed on a tv and all the imperfections are more apparant, for instance I watch a divx file on my pc and I can see artifacting and clear signs of lossy compression, my TV just doesn't show that as clearly because it isn't as high a resolution.

And I'd say that from the same proportionate distance dvd's look better on my monitor than through my tv

The scanlines on a TV blur the image and smooth out the edges so you can't tell the quality is worse.
Thats why a weaker signal almost always looks better on inferior equiptment, because you notice the static easier.

There's several reasons why DVD looks better on TV. One reason is that a TV has a very different gamma to a monitor. Broadcast and DVD material will usually look too dark on a computer monitor unless you do some serious gamma correction.

A TV also has limited bandwidth. Typically they struggle to do much over 6MHz video bandwidth, compared to 150MHz for a monitor. One side effect of this limited analog bandwidth is that it acts as a line orientated antialiasing filter. Additionally, as the TV isn't as high res as a monitor, the image is a little soft, meaning that those low resolution pixels are less square and more rounded and diffuse. A monitor on the other hand is working hard to ensure that each pixel is visible as sharply as possible.Throw low resolution pixels onto such a display, and it's really obvious where the edges are!
