Clean_your_projector_air_filters Cleaning your air filters should be done on a regular basis.

Regular maintenance on your projector keeps your projector running smoothly. Part of that is a regular cleaning of air filters.

Today’s 1080p projectors generate a lot of heat from their sophisticated optics. To prevent overheating, projectors have a system to draw cool air in via a intake vent. Since you only want cool air coming in, these air vents have filter covering them to catch dust and grime. Unfiltered vent allow dust particulars to settle inside the projector and these can actually catch fire if they get hot enough.

Most manufacturers recommend cleaning the filters once every 100 to 300 hours. Clean or replace the filter whenever you notice an excessive build up of dust or if any warning signs appear on screen.

Prevent clogs

Air filters that are not cleaned on a regular basis become clogged and prevent the cool air from being drawn inside.  This can cause the projector to overheat and even shut down. You also want clean air filters to prevent dust from  settling onto the  projector lens. When this happens, the projected image may become distorted or the colors may dull and you’ll need to get the projector professionally cleaned.

Warning signs:

It’s time to clean your air filter when you notice these warning signs:

  • the temperature warning starts blinking orange or red. The color depends on the manufacturer and projector model. A solid color usually indicates that the projector has overheated and will shut off automatically.
  • You can see dust on the projector’s fan exhaust vent.
  • The projected image gets noticeably darker or starts to deteriorate

To clean the filter:

Some manufacturers don’t recommend cleaning the air filter and will supply a new air filter usually when you purchase a new projector lamp. Consult your manual for more details.

  • Don’t wash the filter with soap or water as this can damage the filter membranes.
  • Vacuum the filter with a vacuum cleaner designed for computers and other office equipment. DO NOT use a regular vaccum cleaner.
  • Use a can of compressed air to blow the dust away.
  • Gently shake out the filter to release any dust.

NOTE: Never clean the inside of your projector with compressed air. All this does is blows the dust deep inside the projector.

Consult your manual for step-by-step instructions on how to clean the air filter.

Projector_DVD_Tvs_hook_up_AV_source

No need to throw out the old TV or even replace the DVD players if you want to use your DLP projector. Learn how to hook them up to your projector through your AV source and watch TV in a cinema-set up.

Step 1: Determining output

Projector_Connected_Cable_TV_hook_up_AV_source

Follow these steps to get your AV source set up:

Older TVs are not going to have an outgoing video connection. The newer smart TVs do have this connection making an AV source hookup easy. Check out the back of your TV to see if you have a VIDEO OUT section with any of the following plugins:

  • RCA: composite video (yellow) and stereo audio (white and red) plugs. Similar to headphone or video gaming plugs.
  • S-video: All in one cable using a four-pin DIN connector
  • HDMI: High-Definition Multimedia Interface connector integrating 19 cable pairs. This single-cable, all-digital solution is becoming the industry standard. Used with most HD devices.
  • DVI: Most common digital video cables, similar to VGA connectors, with up to 24 pins. Supports analog as well as digital video so it most used with desktops and LCD monitors. It doesn’t do video so replace it with HDMI cables.
  • VGA: Video Graphics Array connector has a 3-two, 15-pin connector and is used for video cards, computer monitors and HDTV.

If your TV has any of these plug-ins, then you can hook up directly rather than using cable. You should visit our How to connect your DLP projector to a TV for step-by-step instructions.

Step 2: Hooking up the AV source

Projector_DVD_cables_hook_up_AV_sourceIf your TV doesn’t have a outgoing video connection you will need to attach it to an AV source in order to convert the older broadcast signal into a useable video and audio signal. You can use either a DVD player, Blu-ray player, cable/satellite box or game console.

Most cable boxes are going to have either the RCA (composite), S-video (DIN connector), red/green/blue RCA jacks (component) or HDMI or DVI outputs.

To start:

  • You’ll be connecting the TV to the cable box and then the cable box connected to the projector.
  • Use a coaxial cable (orange RCA cable) from the back of your TV into the cable box VIDEO IN jack.
  • Connect a set of audio/video or S-Video cables from the VIDEO OUT of the cable box. A DVI component is preferable but you can use the RCA jacks. The red/white jacks would be connected to the AUDIO IN jack on the projector and the yellow RCA jack would go into VIDEO IN.
  • If you are using the VCR/DVD as your source, it’s the same procedure but you will be using the RCA combo. Connect the TV to the DVD player. Then connect the VIDEO OUT and plug in the yellow jack, find to VIDEO OUT jacks and plug in the red/white jacks. Plug the other end into the projector.

Step 3: Adjusting the picture after the AV source connection

Projector_Image_Adjustment_Connect_Via_Cablehook_up_AV_source

  • Turn on the projector.
  • Go to the MENU or SETTINGS menu on the projector. Go to the INPUT SOURCE and change to the appropriate jack used. Some projectors have an SOURCE SEARCH button or function that will automatically find the video source.
  • Remember that your projector will be reading what is on your TV screen. So if the TV screen in dark or blank so will be the projector.

Step 4: Tweaking the sound quality after the AV source connection

Since most projector don’t have high quality, you may want to use surround sound speakers. This is easy to do it you are using the RCA jack set-up. Simply unplug the RED and WHITE cables from the projector and plug them into the AUDIO IN slots on your sound source.

Happy viewing.

No matter what the brand, at the heart of any DLP TV the DMD chip invented in 1987 by Dr. Larry Hornbeck of Texas Instruments. This optical semiconductor contains an array of up to 2 million hinge-mounted microscopic mirrors, so small they measure one-fifth the width of a human hair.

As the chip receives the signal, small mirrors rotate, either tilting away or towards light to produce those stunning images that have made RPTV a favorite for viewing. Since they are mounted on a yoke with an axle that twists in the middle, these micro mirrors get stuck so they can no longer reflect the signal. The result is a white or black dot on the screen. As more and more mirrors become stuck, more white dots appear on screen creating an un-viewable image.

Here’s what to consider while buying a gaming projector.

 

Video_Game_Projectors

Video gaming is now a mix of data and video where you need clear text alongside with cinematic visuals. Sophisticated game consoles have become hubs for gaming but also staying connected online.  Projector technology has also progressed while prices have dropped making it possible to build a home entertainment center with a video gaming component. For just a few dollars more, you can replace the flat screen TV for a gaming pro.

Video_Porjectors_Specifications

Resolution

While the conventional  VGA, SVGA and XGA projectors are sufficient for an office Power Point presentation, they tend to disappoint when it comes to gaming.  HD is the for advanced visuals, particularly with projectors geared specifically for gaming on the big screen. These day all video and sound quality have an output of 720p or 1080i. Except the next generation and the whole industry to be moving to 1080p projectors for the best graphics possible. However, while the cost of some 1080p projectors is still quite high, the prices for 720p projectors have dropped considerably so there are some great gaming projectors out there.

Video_Projectors_What_to_look_forBrightness

When it comes to gaming brighter is always better. You need to consider the ambient light that will be coming into the viewing room. More brightness can add to the cost of a projector but invest in a more lumens can be a smart choice in the long run. Video games always look better with at least 350 ANSI lumens on a 16:9 screen. The brighter the ambient light, the higher the lumens need to be. Rooms with average ambient light will need projectors with 1500 lumens or brighter. Those with lots of bright light will need a projector with at least 3000 lumens or more. Most video game console controllers are not backlit so that extra lights can make a big difference.

Contrast Ratio

Most video games include a high dynamic range – which is needed for those dramatic, dark moments in a game. So, you need to pay close attention to the contrast ratio in the projector. A passable contrast is 5,000 to one, a  mid-range would have a contract of 4,000 to one. The absolute best contrast ratio would be 100,000 to one that gives greater clarity.

Video_Gaming_Projectors_ChoicesRefresh Rates

When gaming you want a crisp, seamless image. The refresh rate refers to a projectors ability to process the video signal. The faster the refresh rate the shorter the lag time getting the image on screen. Flat panel HDTVs often suffer from motion blur that cause ghosting or an after image left on screen after the scene has changed. With the improved technology ghosting and motion blur have been cut down A refresh rate of 120hz is good and you won’t notice any lag more seamless and crisp the image will be. The highest refresh rate is 480hz.
