It's 120Hz and 1080p. Windows 7 will not give me a 120Hz option when looking in the Nvidia control panel. My TV has a combined HDMI/DVI port but no DVI only port. I've read that using a dual-link DVI connection will allow 120Hz. I do not have that option as my TV does not have that exclusive port.
Take-home whitening kits include custom-made trays and typically use a stronger bleaching agent than over-the-counter systems. In-office teeth whitening treatments by a dentist can cost $300-$1,000 or more, but average about $500-$700. These typically use a high concentration (15%-43%) of fast-acting hydrogen peroxide; the teeth not being treated and the surrounding gums are covered with a protective coating or rubber dam.
Teeth whitening options vary in price and effectiveness. Laser treatments tend to be at the higher end of both ranges. Although the price will depend on your dentist and the discoloration of your teeth, you can expect to pay around $1,000 for the procedure. Looking at the time cost. If you are a busy person on the go, time costs are important to you. If something takes too much time, some people tend to move on to the next thing. Fortunately for these people, a laser teeth whitening appointment can fit into anyone's busy schedule easily. The whole procedure takes about one hour.
