TFT means Thin Film Transistor. It is just a specific type of LCD screen, so yes, it has the same native resolution issues.
If you think about it actually, even a CRT has a "native resolution", because there are a fixed number of RGB phosphors on the screen, and a fixed number of holes in the shadow mask.
So really, if you get an LCD with high enough native resolution, then you're gonna get to a point where you'll get the same qwuality as a CRT in non-native resolutions. But I bet by that point it will become painfully obvious how blurry crt's really are at high resolutions. :-)
Btw, there's a new technology coming to retail in the next year which will allow CRT like pictures on screens as thin as an LCD, and cheaper than an LCD, and with the same low latency as a CRT.
A CRT has a single electron gun at the back of the screen, and magnets steer the electron beam to scan across and down the screen to illuminate the phosphors. This gun is why the CRT is so big. It's been a physical limiations that they can't put it closer to the back of the screen I guess because the angle would be too great to reach the sides and get a proper image.
Well this new technology does away with a single electron beam and instead makes one tiny electron beam per pixel using carbon nanotubes as tiny electron guns.
An LCD doesn't make pixels glow like a CRT, it has a transistor at each pixel and makes crystals opaque or transparent, showing through a backlight on the display, and light will sometimes bleed at the edges of the screen, and around pixels, which is why you have a hard time getting high contrast ratios. (Meaning how black black is, vs how white white is)
This new technology doesn't have that problem. It should look just like a CRT display. In fact, I suspect it will look quite a bit better than a CRT display, because CRT's rarely have a perfectly square image, that's why you've got "pin balance" and "rotation" and "skew" and all those other adjustments you can make to try to fix the picture up. With one electron gun per pixel, ALL that crap should go away comeplely. So it combines the best of CRT and LCD.
I wish I could rememebr the name of the technology. I think I heard it was coming out next August.
