Philips defines different resolutions accepted from pc and other sources (same port)

As we all know many companies and also philips specifically hqave different

resolutions accepted for

pc format

and

video format , through the same hdmi port


i am interested in the 37pfl7603D for example full hd tv (1080p)

which has the following specs


Supported Display Resolution

Computer formats 640 x 480, 60, 72, 75, 85 Hz , 800 x 600, 60, 72, 75, 85 Hz , 1024 x 768, 60, 70, 75, 85 Hz , Via HDMI/DVI input,


Video formats 480i, 60 Hz , 480p, 60 Hz , 576i, 50 Hz , 576p, 50 Hz , 720p, 50, 60 Hz , 1080i, 50, 60 Hz , 1080p, 24 Hz, 25 Hz, 30 Hz , 1080p, 50 Hz, 60 Hz


How is it technically explained the resolution is divided in to 2 different categories , pc and video.

I thought that if the panel was (1920x1080) then it could support this resolution even if the signal is from a pc or an external bluer ray player for example.


Which is the explanation?? thanks for your help

is there a difference between a resolution form a pc or a resolution from any other source ?

are there two diferrent types of resolutions?????
