VGA to HDMI Converter

[R3nOSlaPP]

so are you saying that a converter box is unnecessary in my case??

dont wanna waste 60 bucks on one if i dont need to

Just...

They might sell VGA to HDMI converters somewhere on the net, yes. Do they work? not very well.

VGA is analog (which cannot at any point be High Definition) and HDMI is digital. that's two different languages. Can they communicate? Yes, with the assistance of some sort of converter which, from what i've seen, are absolute shit. it will likely break within the first few months of ownership, and will likely never really work properly.

to the person who said converter boxes can convert an analog signal to HD, think about what you just said. if you're sending something an analog signal, that's the best quality the device will see. a converter box is not going to magically insert pixels to make the picture more sharp. even if there was a hypothetical device programmed with such complex algorithms that it could do that, you'd be paying a shit ton of money for it.

a converter box simply translates the signal. it's usually used on older analog TV's to convert digital cable channels to analog so the TV can read the signal.

OP, even if you find a VGA to HDMI converter, it's probably a gimmick. and hell even if it isn't there's not a lot of point trying to convert an analog signal to digital. that's like using 1/0 wire on a 200 watt amp... yeah it will work, but why the hell would you do it?

your wrong about this

thats exactly what a DVD with upconversion does

Just stick with vga to composite

Run the lappy res as low as it will go

Thats it.

Cost ya 40.00

That's not exactly what DVD upconversion is... but whatever. point is VGA to HDMI, not the best idea.

here ya go

When you watch the same DVD in an HD DVD or Blu-Ray player that features HDMI upscaling, the device will automatically add pixels to the video to help smooth out those pixelated images and match the resolution that is being output to the resolution of the viewing area. This is considered a form of interpolation, where new data is constructed within the range of known data points.

HDMI upscaling can also create a progressive scan picture. Progressive scan is when all of the video's frames are drawn in sequence rather then being drawn alternately.

I also was on Amazon trying to figure out how to plug my laptop into my 43 inch Samsung..

A few things to note about my situation..

1. my laptop is VGA only
   
2. my 43 inch, 500 dollar, plasma tv only supports RCA and HDMI where as the 32 inch Toshiba I bought my mother for christmas supports all those AND VGA (go figure)
   

So as kick ass as my TV is at playing xbox.. my puny laptop just won't see eye to eye with the TV

Later on down the road I'll just get a new desktop and a graphics card with an hdmi port built in..

As cool as you would think watching your comp on a tv might be it doesn't really work that well and the resolutions at which your forced to use with said tv can be problematic as well. I tried it for a while when i had my lcd tv hooked to my computer and thought it was cool and all but it just wasn't as good as using my xbox or dvd player was able to play movies, games, and anything else you can now do on an xbox hooked to your tv and internet. Honestly the xbox if you have one would be the better alternative to your lappy since you can pretty much connect it to your computer through the internet and play movies, videos in mp4, music without actually connecting to the tv with the lappy.

The image and table detail the 15-pin VESA DDC2/E-DDC connector; the diagram’s pin numbering is that of a female connector functioning as the graphics adapter output. In the male connector, this pin numbering corresponds with the mirror image of the cable’s wire-and-solder side.

A VGA cable

A Video Graphics Array (VGA) connector is a three-row 15-pin DE-15 connector. The 15-pin VGA connector is found on many video cards, computer monitors, and some high definition television sets. On laptop computers or other small devices, a mini-VGA port is sometimes used in place of the full-sized VGA connector.

DE-15 is also conventionally called RGB connector, D-sub 15, mini sub D15, mini D15, DB-15, HDB-15, HD-15 or HD15 (High Density, to distinguish it from the older and less flexible DE-9 connector used on older VGA cards, which has the same shell size but only two rows of pins).

VGA connectors and cables carry analog component RGBHV (red, green, blue, horizontal sync, vertical sync) video signals, and VESA Display Data Channel (VESA DDC) data. In the original version of DE-15 pinout, one pin was keyed and 4 pins carried Monitor ID bits which were rarely used; VESA DDC redefined some of these pins and replaced the key pin with +5 V DC power supply.

[edit]Cable quality

See also: RAMDAC

The same VGA cable can be used with a variety of supported VGA resolutions, ranging from 640×400px @70 Hz (24 MHz of signal bandwidth) to 1280×1024px @85 Hz (160 MHz) and up to 2048×1536px @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.

[edit]Adapters

There are HDMI to VGA [1] and DVI to VGA adapters, and VGA to SCART converters. [2][3][4]

For a simple VGA to SCART adapter cable to be viable, the display card must have sufficient features. Namely the ability to provide interlaced output and adjust the frequency, number of total scan lines and number of visible lines (the actual resolution) to match those of the prevailing TV standard. [5] Signal incompatibility rises from the fact that SCART uses composite sync, so either display card must be able to do so too, or sync signals must be summed with a simple circuit. Additionally some TV sets may require 1 volt voltage on SCART pin 16 as explicit signal to use component instead of composite signal. [6] Likewise, three conductor analog RGB signal uses composite sync on green, but a converter circuit for to achieve that is simple as well. http://www.epanorama.net/circuits/sync_r.html

HDMI/DVI to VGA adapters do not carry the audio channel. Separate audio cables are used.

HDMI to VGA adapters generally won't be useful as most displays can't read analog over the HDMI port. The display's EDID can still be read.
