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.
The gel stays on for 15 or 20 minutes. That process is repeated once or twice. Sometimes the dentist aims a light at your teeth to speed up the whitening (although most studies show the lights donât do much). This whole treatment costs around $500 or $600, but many dentists offer discounts to attract new patients.
