Can I use it as tv with my set top box via hdmi cable?
I also want to buy a seperate cpu unit for that LCD Monitor. What specifiction needed in my pc to use this monitor?
Intel graphic card is okay to use it or not?
ANSWER: Yes if it offers an HDMI input, as specified, it will connect to the cable box. As far as a computer, it would need to have a video output that can connect to the monitor - such as VGA. Modern Intel graphics ("Intel HD Graphics") would be suitable for that; if you wish to play demanding 3D games you will likely need a more powerful graphics card, like an nVidia GeForce.

QUESTION: Can I use hdmi and vga port of lcd in a dual use? Means when my set top box is on(cpu is off) and while using my pc cable box should be off. To avoid ReInsert of cables again and again I think it could work?? Both cables connected to lcd for cable box(via hdmi) and pc via(vga cable)?
I think you understand my concern?
Yes that makes sense - and yes that will work. The monitor will likely automatically switch inputs based on what's powered on (it also probably has a "preference" if both devices are on) as well as allowing you to select input via the on-device controls (buttons on the monitor); thus overriding the automatic switching.
