There's not much incentive to do it anyway. If they spend an extra
couple of quid or whatever and fit an oscillator that's well up to the
job, then claim that the TV can handle 1920X1080 on the VGA port, how
many extra TVs will that sell? How many complaints will it bring in
from customers who plug in cheap video cards and find it doesn't work?

I think if you look at a few circuit boards you'll find that crystal
oscillators are pretty much standard wherever oscillators are needed in
digital circuitry, except where there's a special requirement for a
different type. A designer who wanted something with the much lower
stability and accuracy of an LC tuned circuit would probably have to go
out of their way to design it with discrete components instead of using
a ready-made module, or an integrated circuit with a couple of terminals
intended for a quartz crystal. Somehow I doubt this would reduce the
price, and might even increase it.

The alternative is to save a bit of money, down-spec the resolution of
the VGA input and expect anyone that wants full resolution to use an
interface that was designed for the job from the outset rather than
one that's now well into "legacy" status.

I thought VGA *was* designed for the job, the job in this case being
that of conveying RGB analogue video signals along a couple of metres of
cable, though I have used 10 metres with no problems. I can't think why
it should suddenly stop working just as well as it ever did simply
because somebody has invented something else. Legacy or not, all my VGA
monitor connections still work, and in the one instance where I've been
able to make a direct comparison with digital, simply because all the
equipment can handle both interfaces without altering anything else, I
cannot see any difference.
