A VGA splitter is a device that duplicates a VGA signal. In other words, in accepts one VGA input, and clones it to multiple VGA outputs.

VGA Splitters Explained

VGA Splitters and Screen Capture

VGA Splitters are often used in screen capture solutions where a VGA signal needs to be captured. Since a VGA splitter clones a single VGA signal into two or more feeds, this allows the user to retain the use of a standard computer monitor, while at the same time sending the VGA signal to a capture device like a frame grabber.

Active and Passive VGA Splitters

Two different types of VGA splitters exist. Active VGA splitters and passive VGA splitters. Passive VGA splitters, pictured below, are also known as simply Y-splitters or Y-adapters:

Passive VGA Splitter

Active VGA splitters, on the other hand, consist of hardware devices that need to be powered to operate and often have more than 2 ports on the output side. A VGA Splitter from Kramer Electronics is shown below:

When to use a Passive Splitter

A passive splitter has only a few advantages over its active counterpart. Firstly, passive splitters are extremely cheap in price, as they can often be found for under $10. Secondly, they are compact and require no power source.

Unfortunately, passive splitters also have some downfalls. They are not compatible with all equipment, as passive splitters don’t let monitors properly identify themselves to the VGA source. Passive splitters support  a maximum of only two outputs and, since there is no amplification of the signal, the outputs are often of inferior quality than if seen without the splitter.

It is suggested to use a passive splitter when you are connecting two of the same model monitor to the splitter’s output, no power source is available, or when picture quality is unimportant to you.

When to use an Active Splitter

Active VGA splitters have countless advantages over passive VGA splitters. Active VGA splitters can clone one VGA port into virtually any number of outputs. Furthermore, an active VGA splitter identifies itself to the computer as a monitor, meaning that there will be no incompatibility issues with the different models of monitors and VGA-based equipment connected to it.

Furthermore, active VGA splitters slightly amplify the signal (not to be confused with VGA amplifiers) which means that the resulting VGA output will be of significantly superior quality when comparing to that of a passive or Y-splitter.

Realistically, the one and only disadvantage of an active splitter is that it requires a power source for it to operate.

Conclusion

If possible, using an active splitter is recommended for all applications. However, since proper active splitters retail for well over the $100 mark, a passive splitter will sometimes suffice.

When choosing an active VGA splitter, always make sure to check its specifications in order to see if it is compatible with the resolution you plan to use it with.

According to the product page, shipping of the Lecture Recorder will start sometime in November. Epiphan Lecture Recorder, or ELR in short, has some promising features that, at the price tag of $2000, are unbeatable by similar offerings.

ELR’s Unique Features

Even though this product seems to be aimed at the educational market, Epiphan Lecture Recorder has some unique features that make it a perfect frame grabber for pretty much any application. Firstly, ELR supports not only DVI and VGA capture, but also has on-board inputs for composite video and stereo audio.

Furthermore, Epiphan Lecture recorder has a very generous 32GB of buffer memory, which is expandable via portable flash sticks, network drives, or external hard disks.

Finally, ELR features 5 USB ports for external devices and peripherals, meaning that you can create software that will allow you to connect external control devices such as IR remotes, CD/DVD writers, wireless modules, an so on.

Open Source

As mentioned earlier, Epiphan Lecture Recorder will be an open source device. What this means for developers is that it is possible to access all features of the frame grabber. And, because the ELR is more of an embedded computer or internet appliance, many interesting applications can be written for it. For example, the ELR, as it has an Ethernet network interface, can function as its own server, as pictured below.

In a Nutshell

The Epiphan Lecture Recorder is more of a computer with on-board frame grabber and video and audio capture cards than it is an actual frame grabber. While this might not be the ideal device for the general public, the ELR could be used as a platform for a wide variety of applications.

ScreenSnapr is a simple screen capture utility. The free version has no expiry date and lacks some of the more interesting features such as posting screenshots to Twitter, something that the full version includes, for a fee of 5$.

Since paying for screen capture applications is nonsense (browse our website to see that there plenty of free apps available), let’s have a look at the features of the free version:

• Unlimited 1-click uploads
• Custom FTP uploads
• URL shrinking
• Custom GUI
• Dual-monitor support

Using ScreenSnapr

ScreenSnapr is launched by a shortcut that is predefined within the program. The program settings are very simple and self-explanatory. FTP settings are easily configured.

A simple window pops up as soon as you create the shortcut. Note that the Tweet option is not functional in the free version of ScreenSnapr.

Conclusion

ScreenSnapr, while still in beta, is a very simple application with no real features that make it stand out. Even free web-based screen capture tools such as Aviary are more advanced than ScreenSnapr, and do not require a payment to use the full version.

Overall, it’s a nice program if you often upload screenshots to FTP, but otherwise it’s best that you evaluate some other alternatives, many of which are available by browsing this site.

You may read more about and download ScreenSnapr at ScreenSnapr.com.

Features:

• take a screenshot of your complete desktop, a rectangular area or capture a website
• take screenshot directly or with a specified delay time
• save the screenshots to a specified directory and name them in a convenient way
  (using special wild-cards)
• Shutter is fully integrated into the Gnome Desktop (TrayIcon etc.)
• generate thumbnails directly when you are taking a screenshot and set a size level in %
• Shutter session collection
  • keep track of all screenshots during session
  • copy screeners to clipboard
  • print screenshots
  • delete screenshots
  • rename your file
• upload your files directly to Image-Hosters (e.g. http://ubuntu-pics.de), retrieve all the needed links and share them with others
• edit your screenshots directly using the embedded drawing tool

It works like your standard screen capture program (we review such programs all the time) and does not yet have a video recording feature. The program can be set to run automatically as soon as you press the PrtScn or Alt+PrtScn buttons. Read here about configuring Shutter to activate automatically.

Extended Features/Plugins

One neat thing about Shutter is the support of plugins.

These plugins are able to create effects similar to those in GIMP and PhotoShop but directly in Shutter, making it a nice tool for web developers who want to add effects to images on their website, but either don’t have the expertise or the time to do so. All plugins have a slate of settings to make your image look just the way you want it.

Uploading your Images

Shutter lets you upload your screen captures to a wide variety of free image sharing websites. One of the neatest feature of the upload feature is that you get embed and direct links to the uploaded images right away, without the need to launch a browser.

Conclusion

Shutter is a very powerful and fully-featured tool for capturing still screenshots within a graphical Linux environment. As a matter of fact, it surpasses many of its’ Windows counterparts in features, ease of use, and usability. For more information about Shutter for Linux visit http://shutter-project.org/.

Epiphan Systems, the manufacturer of external frame grabbers, recording, and broadcasting solutions for VGA and DVI has announced that all of its’ devices run smoothly under a Windows 7 environment and that the latest version of their software includes full support for this new operating system.

However, users may encounter some difficulties upon upgrading to this new OS, so it is still recommended that you reinstall the software when upgrading from XP or Windows Vista, as the drivers might not remain after the update.

ScreenCaptureNews will keep you updated as more software and hardware developers announce their products’ compatibility with Windows 7.

1. Capture your screen with the PrintScreen button
2. Annotate, draw, and add notes to your screen capture
3. Upload screenshot directly to Facebook, Twitter, Picasaweb, Flickr, or PrintScreen.Me’s free image server.
4. E-mail, print, or archive the screen capture.

Using PrintScreen.ME

You must first download and install the PrintScreen.ME program, it is available as a free download and works with Windows machines only. Once you install the program and run it, it will prompt you for a user name and password:

You must set up an account over at PrintScreen.ME. Luckily, the only personal information that is asked for is an e-mail. If you don’t want to disclose your e-mail address, however, anything may be entered into the box, as PrintScreen.ME does not require e-mail verification. After creating your account, you will be prompted to enter your account names and passwords for photo sharing sites like Facebook, Flickr, Twitter, etc.

The entire setup process takes less than 2 minutes. Once the program is installed, an icon should appear in the lower right (this screenshot was created with PrintScreen.ME):

Now, upon pressing the PrintScreen button you will be able to use PrintScreen.ME to edit and upload your screenshots. Here is a more detailed breakdown of PrintScreen.ME’s annotation features:

The verdict?

PrintScreen.ME is an extremely easy tool to use and comes in very useful. However, it has one huge drawback which is my reason for removing this program after using it for a day - no dual-screen support. This means that there is no way to capture the image on your second screen. It’s very upsetting that a fairly good program would not support such features, when the standard PrintScreen functionality in Windows camptures multiple monitors without a problem.

TV-out devices

The first way to output your DS’ screen to a monitor or TV is by using a third party TV-out device made specifically for the Nintendo DS. Initially, there were two different models available, but only one is being produced now.

The now discontinued DS to TV adapter was made in Taiwan by Q-Mark. This is the best TV-out device available for the DS, letting you see the output of both LCD screens on a TV. The downside to the Q-Mark device is that the DS has to be modified in order to accomodate the TV adapter, making it bulky and less portable. The Q-Mark device is shown below.

Another screen capture device for the Nintendo DS is the camera-based “Video Game Controller Adapter,” also made by Q-Mark. It can be purchased here and consits of a small device the slips over the upper screen of the DS, pictured below.

The latter device consists basically of a camera that is pointed at your screen, and, because of the way it is attached to the DS, only one screen is visible. Of course, quality is compromised as the camera optics are not of extremely high quality and lighting conditions severely impact this device’s operation.

Either way, if it becomes hard to find the DS to TV adapter and only the camera-based Q-Mark unit is available, it is still tolerable, as long as you intend on playing on one screen only.

Recording and broadcasting video from the Nintendo DS if using TV-out devices

If one of the devices mentioned above is used with the Nintendo DS, and the goal is to capture the video in order to record it, share it on a site like YouTube, or broadcast it, any capture card or video card with Video-in (RCA) will do the trick. YouTube even supports on-the-fly recording, so as long your capture card or video card is set as the webcam device in Windows, and  your DS is connected to your capture card via one of the DS-to-TV adapters mentioned above, you’re ready for recording!

For live broadcasts, a variety of software can be used, but we recommend the free Windows Media Encoder. Details on how to use Windows Media Encoder in order to broadcast a video stream from an external device can be found here.

Using an Emulator to Record Gameplay

Using a software emulator on a computer is the cheapest and best way to record gameplay of the Nintendo DS, but is only really suited for short operations and not intended for lengthy game play. An emulator is a software program which replicates the functions of the Nintendo DS. In order to load games to it, you will need to find “ROMs” of each game. Downloading ROMs may be illegal depending on the laws of the country where you live.

Follow this link for a list of free emulators for the Nintendo DS. Once the emulator of your choice is up and running, you must simply capture your screen using either software for screen capture (we have reviewed lots of different programs in our Software as well as News sections) or by connecting a frame grabber to your computer monitor.

How it works

The way it works is quite simple, just place www.aviary.com/ before the URL of the webpage that you would like to capture.

Once that is done, you will be taken to a loading page, it means that your capture was successful and the Aviary image editor is starting.

You will then be taken to a full-blown image editor, as pictured below. The features are pretty self explanatory. Once you are done editing, you may click on “save to desktop” or “save & host online,” depending on what you would like to do with your saved capture.

Advanced Screenshot Editor

The most amazing feature of Aviary is, by far, the advanced editor, pictured below. It can be accessed by clicking on “Advanced Editor” in the top right of the window.

Those that work with Photoshop will have an easy time adapting to the advanced image editor, which tries to replicate the Photoshop interface and functions with some features like layers, history, magic wand, smudge tool, liquify tool, freeform selection tool, and more. All these features definitely make this web based applet more advanced than most free screenshot editors which need to be installed. What’s more, Aviary works with all operating systems including Windows, Mac OS and Linux, and allows for direct uploading of an image to the Aviary web servers, where you can share it with others.

Conclusion

If you don’t have a webpage screenshot editing tool that you’re used to, or if you’re looking to try something new, I would definitely recommend Aviary. It’s easy to use, it’s free, and it’s packed with features that you won’t find anywhere else!

The first thing that you may notice is that the VGA2Ethernet has much higher specifications than any other frame grabber on the market. This is due to the fact that the VGA2Ethernet is a  much more sophisticated device and, as such, is not really comparable to the other grabbers.

Why is the VGA2Ethernet different?

You can think of the VGA2Ethernet as a separate small computer equipped with a frame grabber. As such, it is able to function remotely. In other words, the VGA2Ethernet does not have to have close proximity to the target computer, as is the case with PCI or USB based frame grabbers. As shown below, the only requirement for the VGA2Ethernet is that it be on the same network as the target computer, and within proximity of the source that it is capturing the VGA signal from.

The fact that the VGA2Ethernet can be separated from the target computer distance-wise is not the only thing that makes this device different from others, however. By using the Gigabit Ethernet bus to transfer the images and a PowerPC processor paired with an advanced FPGA, the VGA2Ethernet is able to digitize images at resolutions up to 2048 x 2048 and, depending on the change in content from frame to frame, transfer them at up to 120 frames per second, making the VGA2Ethernet significantly faster than other any frame grabber available on the market.

The introduction of high-speed broadband internet to people’s homes meant that internet users could now share vast amounts of files and information with each-other. P2P and file sharing started out with music and has evolved into a medium through which all kinds of data and information is shared.

ScrnShots has taken the evolution of online file sharing further by offering an unlimited screenshot sharing service. In other words, you can take screenshots from your computer, post them online, tag them and name them. Other people will be able to view your screenshots and comment on them and you will be able to do the same to others.

ScrnShots Main Page

As soon as you load ScrnShots, you are able to search for screen captures simply by typing in a keyword, as in the example above. If you have an account, you may comment other people’s screenshots and upload your own screenshots to share.

Uploading to ScrnShots

Uploading to ScrnShots may be done in two ways. First, you may take your own screenshots, save as picture file and upload using a browser uploader, or you may install the ScrnShots application, pictured below.

ScrnShots capture application

The advantage to using the application is that you are able to instantly upload the screenshot, it is available for Windows and MAC OS.

For developers, ScrnShots offers and API for Windows and MAC OS, allowing you to integrate ScrnShots’ functionality in your own programs. In other words, using the API, a program can be made to upload images directly to the ScrnShots server.

Final Thoughts

While the idea of sharing screenshots is great, there are many other services that would accomplish the same thing, such as Flickr or Google’s Picasaweb, which also allow you to upload large resolution pictures, tag them, and search them. ScrnShots’ interface is very straight-forward and easy to use, which does make it a good service if this is what you are looking for.
