    Projector settings help(?) for a beginner

    It is unknown whether the noise (you can call it snow) is in the source or was created in your equipment. If the noise is in the source, you can't fix it, only possibly make it less obtrusive. You will have to try a few things, one after another. 1. Try turning down the contrast. The...

    What is the difference between a $17 and a $150 HDMI cable?

    For speaker cables, Romex cable works just as well as Monster cable (assuming the same gauge with or without oxygenation) although Romex doesn't look as nice. For video cables, bandwidth can pose a limitation. If the el-cheapo cable works fine at 480p and not so well at 720p, or if the...

    Selling a DLP

    Does it have an HDMI input? Does it have native input, for example if it is 1080 it accepts 1080p? If not then consider it a giveaway.

    Screen gain of every day items like white paint; construction paper, and a sheet.

    Flat as opposed to glossy Not flat as opposed to curved Have to make a new post instead of edit my previous post because the edit button did not do anything.

    Screen gain of every day items like white paint; construction paper, and a sheet.

    White flat surfaces have a "screen gain" roughly equal to one. But the bed sheet has a gain less than one because a lot of light is lost behind it. Alas the classroom projection screen or the home slide projector screen from days gone by is obsolete because it is square as opposed to "wide".

    5.1 vs 7.1

    You may not connect two sets of amplifier terminals to one set of speaker terminals. Generally you may use the 7.1 receiver with the 5.1 speaker set leaving two sets of amplifier terminals unconnected. In a few cases you have to turn the volume for those two channels all the way down. Check the...

    OSD not working, suggestions needed

    How old is the receiver. Many older models provide on screen menus only in standard definition. Just the green cable going from a single video out or monitor out yellow or green jack to the TV green component input jack will display menus not requiring colors quite well.

    connecting 5 output wires to 2 speakers?

    No, you may not connect more than one set of amplifier terminals to one set of speaker terminals. There may be enough blending of the sound tracks as mastered so connecting just left front and right front outputs to the respective two speakers gives correct stereo (2.0) sound, or with a...

    Need Help! Muffled/muted sound from reciever?

    Verify that the tweeter and midrange are working properly by putting your ear up to the front of speaker unit. Adjust the brilliance (tweeter level) and presence (midrange level) controls, if any, in back. >>> the kids play their games, etc. Do they turn the sound up really loud? Could they have...

    choosing between 720p and 1080p LCD TV

    Given the size constraints and in turn the constraints on high definition viewing, this may well turn into a matter of price and weight. THe 720p models cost less all other things being equal. CRT's weigh a lot compared with the newer technologies. If use as a computer monitor is planned check...

    lcd tv on e bay

    I do not recommend buying the TV using eBay. EBay is a means of selling secondhand goods. There is no guarantee it will be working when it gets to you. Quality of packaging depends on how well the seller packed it. Somehow I do not trust even the original box it came in to survive a trip that...

    Repairing a broken projection tv screen; Can one from another TV be used?

    The outer layer (lenticular lens), with the vertical ribs, will probably work well on any TV. The finer the ribs the better. Note that the horizontal resolution is limited by the rib pitch. The inner layer (fresnel lens) with the circular ribs may or may not work out well. If it did not work...

    New basement project- help me choose!

    (copied from another post) The same paint will behave the same way whether put directly on a wall or put on a cloth surface. If you buy paint from "an ordinary paint store" you will want to be sure it is pure white or neutral gray, as opposed to off-white or otherwise having a bluish...

    DIY Screen Paint

    The same paint will work the same way on the wall or on cloth you stretched over a frame or on a "real" screen that is now too shabby to use as-is or whose color/texture you wish to change. When you use a wall for your screen, you may notice that the surface is not as good as it first looked...

    SD DVDs on LCD monitors: Is it just me?

    Does your player output your choice of 480i (native; unaltered) and 480p (already de-interlaced; partially upconverted if you insist)? Try both of these kinds of output to your TV using component video (or HDMI). Poor de-interlacing still exists and at least you can see if the TV does a...

    RPTV video problem

    Unplug and replug each cable end twice. This should clean and improve the connections if that happens to be the root of the problem.

    Projector Aspect-Ratio Issue

    Don't forget: If you do not get an anamorphic lens, an XGA projector cannot use more than 576 of its (768) pixels vertically for 16:9 and in so doing downrezzes itself to standard definition. Unless you want the overall bigger picture for 4:3, there is no great loss in never using the upper...

    Poor contrast = light around my 16x9 screen!

    Put black material (velvet is very classy) above and below the projected area on the screen.

    can I connect more than one speaker on the same receiver speaker connection?

    If you need to connect two speakers to the same amplifier output, you should connect them in series. This way the total impedance is not less than either of the two and burning out the amp or disrupting a transistor is no more likely than using one speaker. A third speaker, if desired, may be...

    projector...computer...and reciever

    The receiver may or may not transcode from VGA (RGB) to HDMI (Y/Cb/Cr) or VGA to component (Y/Pb/Pr) depending on its features. In addition it would have to convert to another resolution (for example 768p (1024x768) to 720p (HDTV) unless the PC video card offered 1280x720 or another resolution...

    How to test speaker wiring?

    Yes the 9 volt battery test works quite well. Disconnect the wires from the amplifier or receiver before doing the test. For polarity you need to be able to see the speaker cone through the grill. Touch the battery contacts to the wires and the cone will move either in or out. Mark each...

    Newb question about projectors

    Yes you will have problems with light in the rest of the room. Turn the projector off. What the screen looks like is what your black will be. Very dark gray, dark gray, somewhat dark gray, etc. will "scale" up from there. When you calibrate the projector for a room where other activities such...

    When anything movies fast, I get this halo, or blanks space effect.

    This is a wild guess. Movies are shot at 24 frames per second yielding 24 poses per second for moving subjects. Traditional U.S. video, both analog and digital, both standard and high definition, is 60 poses per second. Some LCD TV sets put 120 frames per second on the screen. The...

    New guy needs A/V help.

    On your player, try a different setting from the group 1080i, 1080p@24, 1080p@60. For a 720p or 768p TV set also try the choice 720p on the player. Is the audio fed to the TV set via the same HDMI cable or via separate red and white ended cables? Try this both ways if possible. Aside from...

    Question about laying speaker cable correctly

    No problem if the speaker wire runs past the plug socket. You do not want the speaker cable to run right next to and following the same path as the power cable to the plug socket, there should be a few inches separation, some experts say a foot. Since the power cable is inside the wall, it is...

    Best way to preserve Projection Bulb Life?

    (1. If/when the set or projector is turned off, wait a half hour before turning it back on.) 2. Use the set's remote, not a power strip or wall switch, to turn it on and off. The fan needs to run the full cycle to make sure the bulb is cooled down. 3. Use the "low" bulb setting if there is...

    Image retention/burn in using plasma as computer monitor

    Keep the contrast no more than halfway for TV and movie viewing and no more than a third for computing and gaming. You may do your calibrations around the 1/2 contrast and don't bother calibrating for the 1/3 if the TV does not have presets to remember both sets of settings. This way you...

    Is CRT better than LCD (with OTA digital tuner)?

    Perhaps the digital tuner doesn't have enough processing power to regenerate the 1920 x 1080 high def. picture without having to pixellate (checkerboard) here and there. Perhaps these defects don't show up in a SDTV rendering of the picture (S-video is SDTV regardless of the nature of the...

    Pillarboxing problem

    For a wide screen (16:9) TV you set the DVD player to 16:9 period. (The other choices are 4:3 letterbox and 4:3 pan/scan.). You then choose whichever zoom or fit or aspect ratio setting looks best using the TV remote. A program put on an anamorphic DVD as 1.66:1 will have some side bars...
