Q: Connecting your computer to your TV requires connecting the two via a video cable. On the back of your computer, you'll see multiple ports and connectors. Video connectors may be located near the USB, speaker, and Ethernet connections, or you may have a separate graphics card further down the back of the computer. There are three main connectors that you want to look for on your computer:  HDMI - This is the current standard for connecting HD devices, and most modern computers will have an HDMI port on the back. HDMI carries both picture and audio. The HDMI port looks like a longer USB port. DVI - This is a digital connection that uses pins. DVI connectors are rectangular and have three rows of eight pins each. DVI only transfers the image signal. VGA - This is the old standard for connecting display devices. It is a trapezoidal connection with 15 pins arranged in three rows, and is typically blue. Avoid using this connection if you have access to DVI or HDMI, as VGA is the lowest-quality. VGA only transfers the image signal, and cannot display HD images. Once you know the types of connections your computer supports, you'll need to find out what types of connections your TV supports. Most TVs have input ports on the back of the TV, though some have ports along one of the sides.  Most modern HDTVs have one or more HDMI ports. This is the quickest and most pain-free way to connect, and also provides the best quality. HDMI is the only connection method that transfers both audio and video through one cable. DVI is not as common anymore, but can still be found on many HDTVs and standard definition TVs. VGA is typically not available on HDTVs, but can be found on standard definition TVs. This will help you select the correct input when switching to your computer's display. Buying a cable can be a confusing experience, as companies often throw buzzwords around to make their cables seem better than the competition. When it comes down to it, most people won't notice a difference between a cheap and an expensive cable. If you're buying HDMI, the cable either works or it doesn't, so a $5 cable will result in the same quality as an $80 cable. If you don't have a matching connector on both your computer and your TV, you'll need an adapter. For example, if you have a DVI connector on your computer but only have an HDMI port on your TV, you can get a DVI-to-HDMI adapter or cable. In this case, the HDMI wouldn't transfer any audio since DVI doesn't support audio. If you are connecting HDMI to HDMI, you won't need any other cables. If you are connecting using a different method, you'll need an audio cable as well.  To connect an audio cable from a laptop, use a 3.5mm audio cable and connect it to the Headphone jack on your laptop. On a desktop, use the green audio jack on the back of the computer. When connecting the audio cable to the TV, you may be able to use a single 3.5mm audio plug or the stereo (RCA) 2-plug cable. If you're connecting via VGA, turn your computer and TV off first. For DVI and HDMI, you don't need to worry about turning your equipment off. Make sure to select the input that you connected the cable to on your TV. Most TV remotes have an "Input" or "Source" button that will allow you to choose. There are several ways that you can do this, depending on the type of computer that you are using.  Many laptops have a "Display" key that will switch between connected displays. You may need to press the Fn key to access it, and it may just have a symbol instead of the word "Display". In Windows 7 and later, you can press the Windows key + P to open the Project menu. You can then select which display mode you want to use (computer, TV, extended desktop, or duplicate displays). In any version of Windows, you can right-click on the desktop and select "Screen Resolution" or "Properties". The "Multiple displays" menu will allow you to select between the different display modes (computer, TV, extended desktop, or duplicate displays). Your computer's monitor and your TV may have different resolutions, and your TV's display may be blurry when you switch over. Use the "Resolution" slider in the "Screen Resolution/Properties" window to select a clear resolution. Most HDTVs have a native resolution of 1920x1080. Select the "Recommended" resolution if possible.
A: Determine how your computer can connect to the TV. Determine how your TV can connect to the computer. Note the input label on your TV. Get the right video cable for your preferred connection. Connect your computer to your TV using your cable. Switch your TV to the correct input. Switch your computer to the TV's display. Adjust the resolution of the display (if necessary).

Q: In order to create a henna paste and apply a henna tattoo, you will need a few basic supplies. You are going to need two black tea bags, water and a kettle (to make tea), one plastic baggie, and a small plastic bottle with a pointed lid. You will also want to keep some paper towels handy, because henna can be a bit messy. You can find a small plastic bottle with a pointed lid at either a craft store (they are typically used for paint) or a beauty supplies store (they are typically used for hair dye).
A: Gather supplies.

Q: If you'd like your sand dollars to be whiter, or you're having trouble cleaning them with water alone, you may consider using bleach. Mix equal amounts of bleach and water. and gently place your sand dollars into the solution.  If you're cleaning a number of sand dollars, fill a baking tray with the bleach-and-water solution. This will allow you to spread a number of sand dollars evenly over a broad surface. Make sure that there's enough solution in the tray to cover the entire sand dollar. You can also use a bowl, a bucket, or a Tupperware container. If you're only cleaning one sand dollar, find a small bowl, lid, or other container. You won't need much bleach to get the intended effect. Be careful not to soak the sand dollars in bleach for too long: the shell will begin to soften and disintegrate if it's left in too strong of a solution. If you want to soak the shells for a longer period, reduce the bleach concentration. Be careful when handling bleach. Don't get bleach in your eyes, and don't swallow the solution. Wash your hands with soap after any contact with bleach. Move the sand dollars from the bleach solution into a bowl or tray of fresh water.  The bleach may continue to disintegrate the shell even after you've removed the sand dollar from the solution. Rinse the bleached shell thoroughly in fresh water to neutralize the bleach solution and remove any remaining dirt. When you're sure that the sand dollar is clean, leave it out to dry. Within a few hours it should be ready to decorate, display, or store as a keepsake. Sand dollars will harden over time, but you should continue to handle them carefully. This may come in handy if you plan to use if for craft projects, or if you want to display it without worrying about breaking it.  Mix together equal portions of water and white craft glue. Use a sponge brush or a paintbrush to completely cover the sand dollar with the mixture. Let the shell dry, and the glue solution will harden like a glaze. Sand dollars will harden naturally, over time, the drier they become. Bear in mind that thicker glue mixtures may conceal some of the natural texture of the shell. Once your sand dollar is hardened and dried, it's ready to use or display. You can paint or decorate your sand dollars, give them as gifts, or display them as they are.
A:
Soak the sand dollars in a bleach solution. Rinse after bleaching. Consider hardening the sand dollar with glue.
