What is the difference surge protectors for computers versus those for HDTVs?

Some surge protectors indicate protection for computers and equipment while others say HDTV and their equipment. Is there any difference between the two or is it just marketing?

PCs are generally gonna draw more power. its probably a dummy way of telling you what level of protection it offers.

on the other hand, surround sound equipment can draw the power of 10 PCs...so maybe it is just marketing.

A surge protector is an appliance designed to protect electrical devices from voltage spikes. Surge protectors attempt to regulate the voltage supplied to an electric device by either blocking or by shorting to ground voltages above a safe threshold. Following text discusses specifications and components relevant only to the type of protectors that diverts (shorts) a voltage spike to ground.

A power strip is sometimes miscalled a surge protector, but provides no such protection.

Important Specifications

Here are some specifications which define a surge protector for AC mains and some communication protection.

* Clamping voltage - better known as the let-through voltage. This specifies what voltage will cause the metal oxide varistors (MOVs) inside a protector to conduct electricity to the ground line. A lower clamping voltage indicates better protection, but a shorter life expectancy. The lowest three levels of protection defined in the UL rating are 330 V, 400 V and 500 V. The standard let-through voltage for 120 VAC devices is 330 volts.
