Long cables should be of perfect quality with low electric capicitance.
otherise echoes will occure and shadows in picture.
Try a good quality IP- converter set i.e. from EXTRON
You used a shorter cable with better results, so don't look for a cause inside the projector. Picture quality stands with cables !!

There is a lot of cheap rubbish in the market.....

Double image on screen


Hello,
Usualy in these cases I check the VGA cable. If you can buy new one, but not cheap one will solve the problem. Just to be sure that this is your problem hold the small vga cable cylinders with your hands for 5-6 seconds. When you release them you shouldn't see the ghost image on your screen. It sounds weird but it works. By holding these cylinders you remove the static electricity of the cable. Try to understand what device around your monitor causes the problem. The cause also may be lot of power cables or power sources near the VGA cable.

I have an imac, and I just bought an optoma hd65. When I hook my iMac up to the optoma via a vga cable, there is a ghosting effect on the picture. Decreasing the "sharpness" helps a little but...


The adapter would be my first suspicion. Can you find another (better) one to try?

Also check the video output settings of the iMac to make sure its set for a 60hz output (if you're in the us. it's 50hz for Europe)

Hi, I am trying to connect my laptop to my TV using VGA (MALE) to VGA (MALE) cable. I am able to see black lines on the TV with noise.How can i correct this ?


You didn't say, is the TV HDTV??
From Windows help menu, press F1, type in "VGA connection" I found this:

Why can't I hear audio when I connect my computer to an HDTV?

VGA, DVI, and component video cables do not support audio signals. HDMI cables do support audio signals, but not all HDMI-enabled video cards support audio. If your HDTV has an audio input, you might be able to connect a separate audio cable from your computer's sound card directly to the TV. Otherwise, you'll need to connect the audio signal to a different output device, such as external computer speakers or your home stereo system. For more information about sound cards, see Sound cards: frequently asked questions.


From Wikipedia.org search VGA connection:
1.
Video Graphics Array (VGA) refers specifically to the display hardware first introduced with the IBM PS/2 line of computers in 1987,[1] but through its widespread adoption has also come to mean either an analog computer display standard, the 15-pin D-subminiature VGA connector or the 640×480 resolution itself. While this resolution was superseded in the personal computer market in the 1990s, it is becoming a popular resolution on mobile devices.[2]
VGA was the last graphical standard introduced by IBM that the majority of PC clone manufacturers conformed to, making it today (as of 2010[update]) the lowest common denominator that all PC graphics hardware can be expected to implement without device-specific driver software.[citation needed] For example, the Microsoft Windows splash screen appears while the machine is still operating in VGA mode, which is the reason that this screen always appears in reduced resolution and color depth.
VGA was officially superseded by IBM's Extended Graphics Array (XGA) standard, but in reality it was superseded by numerous slightly different extensions to VGA made by clone manufacturers that came to be known collectively as Super VGA.

2.
The same VGA cable can be used with a variety of supported VGA resolutions, ranging from 640x400px @70 Hz (24 MHz of signal bandwidth) to 1280x1024px @85 Hz (160 MHz) and up to 2048x1536px @85 Hz (388 MHz). There are no standards defining the quality required for each resolution, but higher-quality cables typically contain coaxial wiring and insulation which make them thicker. A quality cable should not suffer from signal crosstalk which occurs when the signals in one wire induce unwanted currents in adjacent wires, ghosting which occurs when impedance mismatches cause signals to be reflected (note that ghosting with long cables may not be the fault of the cable but may instead be caused by equipment with incorrect termination or by use of passive splitters), and other signal degradation effects; shorter VGA cables are less likely to introduce significant degradation. Some higher-end monitors and video cards featured 5 separate BNC connectors for RGBHV signal, allowing highest quality connection using five 75 Ohm coaxial cables.

I hope this helps, I find the sales reps at Best Buy very helpful.

Try with a shorter enet cable and see if you get internet, if you are able to get internet with a shorter cable then the cable might not be working fine. Else get a wireless card installed on your computer since the 2wire modem has wireless connectivity. It would be more easy and convenient to connect to wireless using the 2 wire modem.

Is it possible to connect my computer with a VGA output to my HDTV with HDMI inputs?


hi there, sure it is.
either check if the video card has two output interfaces(VGA and HDMI) so use the white HDMI-otlet with a cable and your TV, else do get an VGA-to- HDMI adaptor and try connecting the VGA outlet and your TV-set.

Good luck

The longer one will work, no problem.
Now if the cable was 25 or 50 foot long, that would be a completely different story.
6' is what they consider as the "ideal" length.

Ghosts on my tv


if you can, try hooking up the tv to a different cable line in the house or bring a different tv into the room where the bad picture is [ you may have a bad connection or wire ] if this doesn't help, try rabbit ear antennas just to get a picture. if you still have ghosts on your tv, the problem is with your tv.if the picture is fine, there maybe a problem with your cable service.
hope this helps
