You need to tweak the sensor on the lightgun to be more sensitive, I have seen it done before.

Not possible if you want a perfect experience.

From what I've read on a random forum, if you replace the matte screen cover on your screen with plexiglass one, it may work slightly better.

You're far better off with a tube type television.

AFAIK in most (if not all) cases you simply can't. HDTVs introduce video processing delays that mess up the timing of the white blocks the gun needs to see in order to register shots (Nintendo) coupled with the different refresh rates and overall different technology used in LCD and Plasma, there's no scanning electron beam anymore for the gun to calculate screen coordinates on (Sega).

You *may* luck out with a Nintendo gun on a CRT HDTV with a Game mode or similar, but for everything else just forget it.

I suppose you're referring to the lowpass filter inside the Zapper which caps the light detector at ~17 kHz. If I remember correctly some guy tweaked the filter to cap at ~35 kHz instead in order to get the Zapper working on a PC VGA monitor with software of his own, but that doesn't do anything for the HDTV-introduced delays when playing on the real console. Though it makes me wonder if it would work on a VGA CRT with a high performance scan doubler. ::)

He used a professional video scaler to bypass the TV's laggy internal one, and it is a CRT HDTV.

Professional video scalers are expensive. You could buy many old CRT TVs for the price of one.
