AThis is a link to a website that you can do side by side comparisons.

A Glass for both Xenon/Neon gas is not a semiconductor, it is a plasma in the display Both will also have metal conducting films to get the signals to the display pixels.

Athey have really. the companies are slowly phasing them out, by flooding the market with TFT and LCD screens. As the technology is still comparatively expensive to CRT, it's still being offered as a cheaper alternative.Give it a couple more years and there won't be any new CRTs on sale

AAGP (Accelerated Graphics Port) is an interface on a motherboard for connecting a video card.XGA (Extended Graphics Array) is an IBM video standard from 1990 that supports resolutions of up to 1024 x 768.

AHolographic display technology is still very far off. Holograms are static(non-moving) images. At best, you can only get simple animations that change as you walk past or rotate them side to side. You won't be seeing a holographic TV for quite a while and anythign that claims to be showing you an animated holographic "projection" is simply not using holograms.Other aspects of holograms in science fiction are pretty far from the truth as well. They always show holograms as 3D images projected into space, into thin air...but holograms can not do this. They are not projections. In order for this to happen light needs something to bounce off of and to bend light rays from a point in3D space with nothing there would take tremendous amounts of energy and would no longer be a hologram as it would be something else entirely. Just like looking into a mirror, window, or photograph, you have to be looking into the flat 2D surface on which the hologram is stored to see the illusion of 3D.

AThis link will give you far more insight as to the differences and, how your expectations might be served best..Good LUCK`
