Yes, any screen needs to be set up and calibrated. Straight out of the box from, no computer screen is properly set up for photographic work. They are generally set up for office use, where the light levels are far higher than what is optimal for photo editing.
For photo editing you should profile and calibrate the screen with a Spyder or i1 tool and the screen should be set for somewhere between 80 and 120 candela / square meter. The workspace for editing should be dimly lit (below 70 lux at the workstation and ideally below 30 lux). Most Indian photographers I have spoken with tell me that the Datacolor Spyder line is more reasonably priced than the x-Rite / Calibrite hardware/software.
