vga to displayport adapter
I have use of a v. nice Mac monitor with a display port connection. To
use with my pc laptop. So went looking for a vga to displayport adapter and google brought up Staples, Gearbest, and Amazon, and provided search pages for each of them, and even though I was searching for vga to displayport adapter every hit was for the opposite, displayport to vga. https://www.amazon.com/s/ref=nb_sb_s...KLH 99UU82MWX Am I looking for something that doesn't exist? But this page http://smallbusiness.chron.com/apple...-pc-70386.html says "DisplayPort and Mini Display Port Apple monitors that use the DisplayPort connection standard are fully-compatible with PCs. The DisplayPort standard was designed to compliment the HDMI standard and has similar performance over a smaller port. According to PCWorld, DisplayPort is intended for use with computer monitors while HDMI is intended for consumer devices. PCs that have built-in DisplayPort connections can use Apple's DisplayPort monitors without the need for an adapter. However, VGA-, DVI- and HDMI-supporting PCs can use adapters to connect to DisplayPort monitors. === It says just above that there are adapters but I can't find one. The VGA standard requires a digital-to-analog conversion and consequently features a larger adapter. DisplayPort and MiniDisplay ports can be interchanged with adapters as well." This alternative question seems harder to answer, and I might be able to find out the model number or at least the "name" of the monitor in question, but... Alternatively you could if you want check out this Mac monitor, but you probably don't have to answer the questions below, at B). http://www.bestbuy.com/site/samsung-...rame/5712657.p and then click on the 4th picture and it has inputs for displayport, hdmi, vga, and some round thing I don't recognize. B) But the point is that it has VGA. Is that "standard"? Or is it standard for Samsung. Or do most monitors not have VGA? This series is still for sale, but there was one that looked similar**, was separate from the computer and had a similar stand, a few years ago, that's only for sale used now, None of the pictures show the back. Would VGA have been standard on that too. Or at least on some of them? It's really not worth your time to look at this, because someone will answer my questions without looking, but I'm including it anyhow. The monitors that look the one in my picture are found after these descriptions, which are in chronological order. http://www.macworld.co.uk/feature/ma...ictures-24596/ 28 June 2004: 30 inches or bust Apple calls its 30in Cinema Display “the largest high resolution display ever created.

There is no more beautiful computer. 30 November 2012: Skinny Macs I'm working from a photograph that includes the monitor, and when I looked through Here is a VGA to HDMI. "Portable VGA to HDMI Converter 1080P at 60HZ" --- 1920x1080 http://www.primecables.com/p-331692-...FQMHaQodyHQPBg Here is an HDMI to DisplayPort https://www.startech.com/ca/AV/Conve...erter-4k~HD2DP I think really, it's just a matter of "keep looking" :-) Those are the first hits I could find, to cobble together a solution. No, I don't think finding one will be easy. If you expect an all-in-one solution, the box is liable to be larger than those converters. I would not stop searching, until I found one, as the cobbling might not be as seamless as you would want. But at least I can find two separate functions to get from A to B. Also remember that VGA ports had around a 400MHz bandwidth limit, and maybe 2048x2048 is about as big a picture as they could produce. That means 1920x1080 or 1920x1200 might be theoretically possible, but the image quality doing high res might not be that good. VGA is analog, the 15 pin connector is not the best connector for the job, and so maybe 1600x1200 is a reasonable limit for VGA. You need to compare that to the "native" of the Mac monitor. This is what the VGA connector *should* have looked like. The 13W3 is a better solution to transmitting analog signals. It was the standard connector on Sun computers. The three coaxial connectors could be set up to match the coaxial cable they were connected to. By comparison, the transmission qualities of the DB15 VGA are not as good (reflections off the pins). https://en.wikipedia.org/wiki/DB13W3 ******* It helps to know: 1) Whether the laptop has any output limits on its VGA. Only a really old laptop would have that problem. 2) The native resolution of the Mac monitor. 3) Whether the laptop has enough USB ports to be providing power for the conversion. A 5V wall wart with USB connectors for output, could be used to power the adapters, rather than abuse the laptop :-) ******* The round connector could be a mini-DIN for S-video. That's the connector on the back of your VCR. Four pins would be used, luminance and chrominance, and two ground signals. https://en.wikipedia.org/wiki/S-Video "a signaling standard for standard definition video, typically 480i or 576i. By separating the black-and-white and coloring signals, it achieves better image quality than composite video, but has lower color resolution than component video." The miniDIN has also been used by ATI and NVidia, on their video cards. The two companies do not use the same pinout. The mini-DIN can have 7 pins or 9 pins. The connector can be used for "Output" or for "VIVO". When used for Output, it can do YPbPr, otherwise known as Component Video. There are some nice projection displays that use Component Video, with excellent output. But due to the lack of standardization, when we randomly see a miniDIN on a piece of equipment (like a VCR), it's natural to assume S-Video, and that's all that you're getting. Naturally, 480i sucks. And due to DC restoration problems, very few video card miniDIN outputs look good if used directly on a TV set. I "launder" mine here, by running the S-Video through a channel 3 RF converter, then connecting to the antenna terminal on the TV set. It almost looks presentable then. Without the RF converter, the picture looks like ****. You would think such a conversion would degrade the picture, but the picture actually looks better. I run a DVD player through that converter right now (as running the computer through it was just for testing whether I could fix the DC restoration problem or not). If you have a large screen TV, it may have three coax connectors on the back, with the YPbPr labeling. They stopped making video cards to drive that, maybe ten years ago. Providing such outputs, allows "pirates to copy movies" etc. Terrible. Naughty pirates. Naughty pirates also prevent us from having all the "toys" we might want, like an infinitely capable converter box for Micky. "DMCA". Nuff said. This cable, shows a passive conversion from an NVidia card, to S-video and others. The left hand end plugs into the video card. The right hand end and the miniDIN on that end, would be suited for a VCR etc. The left hand end, has a different number of pins than the right hand end. https://en.wikipedia.org/wiki/File:V...tter_cable.jpg You can see the video card flavors, here. There should be a picture of the seven pin flavor around somewhere. What should happen with these, is the four S-video pins should occupy the same locations on all of the connector flavors. That should be the only "standard"... The other pins, being non-standard, are free to "float around" when they design a connector. Don't lose the adapter that came with your video card. https://upload.wikimedia.org/wikiped...-9_Diagram.png https://en.wikipedia.org/wiki/File:M...-9_Diagram.svg One of the reasons I bought the video card that is on this computer, is it still has the miniDIN on it. I don't have any equipment to connect it to, but at least I own one :-) Mine appears to be the seven pin type. The cable in the box, is seven-pin to YPbPr and that's all. Unfortunately, I don't own anything with YPbPr input, to test the goodness of YPbPr (which is miles better than S-Video). Paul |

The advantage of the Startech products, is they list the chip used. https://www.startech.com/AV/Converte...-1080p~VGA2HDU One reviewer here, mentions that an attempt to output at 720p, the chip output 1080p instead. https://www.newegg.com/Product/Produ...82E16815158397 The MS9282 is the chip in the adapter. And it's not clear whether it is actually passing through the DDC EDID information or not. Or for that matter, how it interacts with the monitor resolution info. http://en.macrosilicon.com/info.asp?...d=2&third_id=3 Paul |

Paul, thanks to you too. I might spend $20 to do this using the adapter you found, but of course that only gets me to HDMI. Then the thing you found to go to Displayport is 90 more dollars!! For 110, I could buy a whole monitor, maybe even a new one. The video card does't put out high def but wouldnt' two conversions still degrade the picture? |
