 It's not the Pi it's the TV.

 There are certainly some TVs (mostly cheap ones) for which the lag
between signal and display is enough to produce a noticable and irritating
mouse lag, other than that the only real difference between a monitor and a
TV is that the has a bunch of stuff (tuner at least) that the monitor
doesn't.

 I get the impression that this applies less now than it did a few
years ago when I learned to be wary of this issue - but that's just an
impression.

 Sure for watching TV where the sound and video come over the same
HDMI link the delay doesn't matter - a tenth of a second lag in responding
to the remote control of a TV is nothing, the same lag on a mouse is
hideous.

 Try it (anything with a mouse or touch screen and HDMI will to to
test) - if you're in a big place like PC wormed then look at a laptop and
then say - "Can I see how it would look plugged into my TV - I have one of
those --->" - then buy the TV you wanted :)

 Some are fine some not so much. Also much depends on your personal
sensitivity to the lag.
