Is it normal for my MBP to run much warmer say 20 degrees warmer when connected to an external display?

Higher temps

I agree with you that an external display will increase the Macbook Pro's temps

I find that just the Macbook Pro by itself, it tends to run @ 110-120, however when it is connected to a Samsung 24" monitor, the temps seems to be @ 135-145.

What are your temps that you are seeing?

It definitely will. It runs the discrete GPU when when you have it connected to an external monitor.

I have an early 2011, 13" Macbook Pro, so it uses the onboard Intel 3000 graphics, so is this still normal that the temps increase by 20-30 degrees when connected to an external monitor?

Perfectly normal, I have mine running wirelessly to a 1080p TV extending my desktop and the CPU right now is currently showing 81C and often peaks to 93C.

Normal. Takes more horsepower to run a higher res.

It is not the higher res.

An external screen always requires the dedicated GPU and a GPU usually has around 3 power states low, mid, high. With any external screen of any size attached it usually never goes lower than mid.

If Apple allowed using the Intel GPU for an external screen it would be much cooler.
