The above article is correct.

You say "monitor" though I assume you mean HDTV. Pretty much any HDMI cable will work fine, though there are different qualities of cables so it's a good idea to have more than one cable for troubleshooting purposes. HDMI version 1.4 is pretty much standard now. HDMI version 2 is for 4K screens.

240Hz:
It may not be explained too well in the above link, however if we're talking 120Hz or 240Hz motion smoothing for example, it works like THIS:
a) 24Hz (Frames Per Second) video is turned into 60Hz signal to HDTV*
b) Several frames are analyzed and THREE MORE (for 240Hz) are artificially created for each "real" frame
c) 240Hz signal is displayed

*In some HDTV's the 24Hz signal is taken in and only displayed at 24FPS (24 times per second) to avoid any pulldown/conversion issues.

Artificially SMOOTHING the signal inside the HDTV causes problems. It's not a good idea for movies for example, because the amount of BLURRING was factored into the Frames Per Second (the lower the frame rate the more it needs to be blurred. It's an eye/brain thing.) It's useful for things like SPORTS where we want to artificially add more frames to track a ball and don't care about the optimal blur amount.

HDMI cables and signal quality:
1) Perfect (no loss from HDMI cable itself)
2) NOTHING (broken cable)
3) Sparkles (in rare cases it's on the verge of not working)

PC Monitors:
Just in case you meant PC monitors, then all you need do is ensure the proper Displayport, DVI or HDMI cable for whatever connection type you are using. The monitor will specify what cable you need to achieve the desired refresh rate and resolution.
