Was ClearType made for only LCDs that utilize DVI or was it just for LCDs in general?

I brought my 2001FP to work and it's running through a KVM so there is no DVI out. I'm using the standard VGA out. Basically without ClearType on the text looks like crap because I'm so used to DVI at home. I turned on ClearType and to my surprise it actually looks like how it does at home even though it's using VGA.

Was ClearType meant just for DVI or both and just specifically for LCDs?

All I know is that on my 2005FPW, when I trun cleartype on, it looks like someone rubbed vasoline on my screen. It's awful.

It works better with DVI. As every pixel and subpixel is where they are expected to be.

Cleartype was made for LCDs. I hate cleartype, it makes my LCD look like a CRT with convergence issues.

For those of you who don't like Cleartype, I wonder if you have it configured correctly. There are varying levels of "smoothing". I can't imagine using an LCD for text-viewing without it.

I set it up on all my LCD systems. CT looks much better than w/o it. You just need to configure it properly as daniel1113 stated.

idk what configuration you're talking about. It's either on or off.

That's if you don't use the configuration tool or ClearType tuning utility on the MS website. Both of those tools allows you to modfy the ClearType settings.

i use cleartype on both analog and dvi lcds. it works fine. the reason they do it is because the pixels are square. its like FSAA for your 2d.

with crts the pixels are not in place so it doesnt matter so much, but it can even help on a very good crt like a trinitron.

Cleartype can only work if there is a digital DATApath to the display - else, the graphics engine has no control over whether the RBG subpixel rendering gets reproduced correctly on the display end of the affair.

Furthermore, since CRTs do not have discrete RGB pixels, they can't reproduce ordered subpixel rendering at all.

So yes, Cleartype can only do what it's supposed to do if given a digital signal path and a non-scaling, 1:1 display LCD screen.

With an analog signal path to an LCD, or a CRT, only "Standard" antialiased fonts make sense.

The rendering isn't being done in the LCD; the graphics card does that.

You absolutely must run that LCD at its native resolution ... and you might have one of those LCDs whose subpixel ordering is reversed.

Also note that ClearType is supposed to make font rendering SMOOTHER, not CLEARER. What it does is triple the horizontal resolution for font rendering, at the expense of some potential for rainbow effects on the edges.

A calibrated LCD and calibrated ClearType gamma will prevent the color fringing on fonts. Though Linux's subpixel rendering is still miles ahead of ClearType IMO.
