Currently I'm attaching my MBP to 26" LCD TV.
Unless you extend to external monitor and play game with ultra high resolution and ultra setting that your MBP's GC doesn't support.
In that case, it will generate more heat and might cause your GC to overheat. It won't be a problem if you use it for normal daily surfing.
Ah i see, yeah that what im afraid. Im afraid if use ex. monitor will produce extra heat. I'm using for normal daily such as doing my Thesis research, web browsing, and writing
Hope its okay for me to connect with ex. monitor most of the time when using for daily works

Btw, I'm using SmcFanControl, and it's show my current temperature is around 40-49c

Hope its a normal temperature.
