If you think it looks "sharp at almost any resolution", then you should try it with test patterns and/or a strong magnifying glass.

Incandescent light bulbs do not have the minimal attributes of a vacuum tube, i.e. having at least an anode and a cathode like a diode tube.

FYI there's a vacuum tube in your microwave oven.

Although tubes in the TV chassis circuitry have been replaced by solid state (i.e. transistors), the CRT display has not (at least not yet).

Maybe that's possible, but it would require a perfectly focused electron beam with a really wide-bandwidth gun (i.e. fast turn on/off), and it could just look dim.
Ditto.
No, display a...

If you considered the construction of three-gun color CRTs, you would realize that you're repeating a fallacy.

From my experience, I would disagree.
A side-by-side test of a Sony 27XBR15 (4:3 SD) to a KV-30HS420 (16:9 HD) (using a CECB as input) is my basis of comparison. By itself the the old SD TV looks...

That's a statement that's often made (along with it's corollary "CRTs don't have a fixed resolution"), but that doesn't really apply to color CRTs. It's really meant to describe a monochrome CRT (or...

Yes, I've done that.

Sounds like you're describing posts I've written.

Then be extremely shocked.
There is absolutely no indication that Linux is running on these boxes as shipped.

A 720p program can be just as large as a 1080i (eg. FOX versus CBS). ABC gives 720p a bad rep because it over-compresses its signal. But FOX does not.

There are low-cost (less than $50) HDMI-to-VGA+stereo converters that have decent performance.

I worked on a HS420 that ended up with similar distortion only on the bottom.
I believe it's called "flagging".

Similar adjustments on an XBR910 were distortion free.

This distortion should have nothing to do with pincushion (i.e. curvature).
You seem to be describing a (horizontal) linearity issue.
