Color, brightness and contrast are very good to exceptional. I am a CAD user and the monitor works great for that and standard office applications (no gaming here). The tilt and height adjustments are greatly improved from my 3 year old screen.
The Power Switch is located on the lower right corner of the frame. It is not a recessed button and there is NOTHING to inhibit accidental power cycles. You will find that you accidentally shut off the monitor regularly.
There are quite a few good monitors in this price/size/performance range. Seek out another choice unless your organization forces Dell products, as mine does.
