INPUT ARTICLE: Article: An HDMI port resembles a thin, wide slot with a slightly tapered base. If you have a receiver with enough HDMI input ports, and your TV has at least one HDMI input, you should be able to connect all of your devices to get the best possible quality from your home theater. Most new receivers will have multiple HDMI inputs that allow you to connect all of your HDMI-capable devices, as well as an HDMI output for connecting to your TV. You can buy an HDMI splitter for a one-port receiver. Check that your TV supports HDMI 1.4 ARC (Audio Return Channel). This allows the TV to send audio back to the receiver, which routes your TV sound through your home theater speakers. Most TVs made after 2009 support HDMI 1.4 and newer. If your TV does not support HDMI 1.4, you will need to use a separate audio cable to connect the TV to the receiver (e.g., digital optical). If you are watching TV through a cable box via your receiver, you don't need to worry about ARC since the sound is coming from the cable box into the receiver. These could include DVD/Blu-ray players, game consoles, and more. If you have limited HDMI inputs, use HDMI cables for the most recent devices first, as they will benefit the most. For example, if your receiver only has two HDMI inputs and you have a Roku, a PlayStation 4, and a DVD changer, plug the Roku and the PS4 in with HDMI, and use a component connection for the DVD player. The Roku and PS4 will benefit much more from the HDMI connections. HDMI plugs only go in one way, so don't force any connections. Plug one end of an HDMI cable into the receiver's HDMI slot, then plug the other end into the TV. This allows the image from all the devices connected to your receiver appear on your TV. Since your devices are now routed through the receiver, the TV can be set to the HDMI input that you plugged in from the receiver, allowing you to switch between inputs using your receiver remote. Since everything has been connected via HDMI, all the sound from your devices should go through your receiver's speaker setup. Most devices should configure automatically when they detect the HDMI connection, though you may need to tweak some settings for certain devices. If you aren't setting up a home theater system, you can still plug your HDMI devices directly into your TV and then control the inputs using your TV remote. Most modern TVs have at least two HDMI inputs. If you have more HDMI-capable devices than you do input ports on your TV, you can purchase an HDMI switch that will expand the number of available HDMI ports. HDMI-CEC allows you to use your TV remote to control your other HDMI devices. To enable HDMI-CEC, you'll have to access each device's settings menu. HDMI-CEC is called different things by different companies, including Anynet+ (Samsung), Aquo Link (Sharp), Regza Link (Toshiba), SimpLink (LG), and more. Refer to your TV's manual for more information.

SUMMARY: Locate the HDMI ports on all of the devices. Check what version of HDMI your TV supports. Connect your devices to your receiver inputs via HDMI. Connect the receiver to the TV. Use the receiver to switch between inputs. Connect your devices directly to your TV. Enable HDMI-CEC if you like.

INPUT ARTICLE: Article: The running water in your shower loosens surface dirt and softens soap residue on your travertine tiles. For optimal results, tackle shower cleaning after your shower has primed the tiles for you. Travertine, like all limestones, is extremely sensitive to acids. Use a non-acidic stone cleaner, such as Granite Gold Shower Cleaner or MB-3, and spray the travertine thoroughly from the top to the bottom. Let the cleaner sit on the stone for 10 minutes to begin dissolving any soap scum. Given travertine's acid sensitivity, always avoid applying vinegars or other citrus cleaners. Fill a bucket with warm water, and begin scrubbing the tiles with it. Use a diamond-shaped brush to wash the entire top row of tiles, applying firm pressure to loosen soap scum. Progress to the next highest row, methodically working your way to the bottom row. This way, dirty water will run down on tiles you've yet to clean. Focus particular attention on any surface holes in the travertine when cleaning, as they can collect soap scum. A diamond-shaped brush makes it easy to clean your shower's innermost corners easily, but any shape is fine. Be sure to choose 0000-grade steel wool, as it is very fine and shouldn't scratch the tiles. Lightly buff away hard water stains with the steel wool. Turn the shower on and rinse your newly cleaned travertine tiles with warm water. If there are any spots you can't reach with the showerhead, fill your bucket up with clean water and rinse the tiles clean manually. Use a towel to wipe down your travertine to remove any traces of stone cleaner. It may be helpful to open a window to dry the area more quickly.

SUMMARY: Clean your shower after you use it. Spray your wet tiles with a non-acidic soap scum remover. Use warm water to scrub the tiles. Remove hard water stains with fine steel wool. Rinse the shower with warm water. Dry your travertine with a clean towel.
