Q & A About Using a USB to DVI HDMI VGA Video Display Adapter

There is a lot of opportunity in how to display your computer signal to other external video display devices, such as a PCI based Video Card, USB or Firewire Based Video Adapter and multi-functional usb display adapter. And now, it seems that dvi hdmi vga to usb display adapter is more and more popular in graphics card converter. Of course, there are significant problem in how to install and debug video display adapter (no signal, no audio, driver compatibility and etc.). Today I want to list some common questions about it. Let's start with one of the most important questions:

Q1: why there is no audio after installing the dvi to hdmi adapter

There's potential for oxidization or dirty or even the bazillionth of a fraction (exaggeration) difference in different metal to different metal contact conduction at the adapter points, but overall both should provide an equally good picture. So, in this situation, you need make sure 2 points:

1.Onboard speakers in monitors usually suck pretty bad, externals are usually much better for pretty cheap.

2.Audio can be outputted over DVI as long as it's a newer ATI video card (not NVidia) using PCI-Express

Q2: The display on the add-on monitor is blank?

A: If the monitor or display screen power LED is green, wait a moment for the monitor to show the video as sometimes it takes time for the add-on monitor to show the video. And if the power LED is red, you should check the power line and battery DC interface. You can also reboot your system to try again. After that, usually it will work!

Q3: The add-on monitor is flickering or low definition

A: This is usually caused by a low refresh rate. In mirror mode, increase the refresh rate of the main monitor. Sometimes, other wirelss devices (cell phone, wireless receiver) may disrupt the display signal. You know, if you use an interference free USB to HDMI Adapter and high quality HDMI Cable, it's ok!

Q4: When I play MPEG/AVI file by Windows Media Player on the extended monitor, how come the display becomes abnormal when I switch it to full screen mode?

A: If your system is Windows XP SP1, we suggest you upgrade it to SP2 to solve this problem. And there is no problem with Vista or Windows 7.

Q5: When playing the video in full screen mode, the motion is not smooth

A: Terminate any other CPU intensive applications running on the computer. If you still have issues playing media content on the adapter, try the following steps: As some media players require DirectX hardware support to correctly operate, try a different media player which requires less DirectX support. Also, if you want to watch full HD movies, you need to use an 37 inch or larger HDTV. Only in larger Monitor, the USB to DVI HDMI adapter can work absolutely. Or, you can only watch edit-movies. Drag the media player to the add-on screen and close the player. Restart the player and it should open on the add-on monitor. Now try playing the media file again. The video playback may be unusual when the add-on monitor is mirroring the primary display and there is another extended screen connected to the computer.

Q6: In extended mode, the add-on monitor appears to have a black border around the desktop

A: This happens when the resolution used by the add-on monitor is larger than the resolution used by the primary monitor. Let's me show you a case that I often play football games on my 42 inch HDTV, and at first, it can't display in full screen mode or extended mode and I change the game setting finally. To solve this problem, configure the add-on monitor to use the same resolution as the primary monitor.

Information About Video Cards

I needed to produce a uncomplicated how-to guide for overclocking video cards because today's newer cards are totally capable of modest overclocking without having damaging them, therefore giving you a free of charge performance upgrade. Nonetheless is particularly essential to note; overclocking technically voids most manufacturer's warranties and can trigger damage to or even ruin your video card if a high degree of precaution will not be taken. This guide is for employing overclocking utilities: ATI Tools and RivaTuner, and we will benchmarking with 3DMark06.

RivaTuner is really a utility employed to adjust GPU core voltage and memory clock speeds. ATI Tools is usually a program for checking efficiency stability and core temperature levels. As soon as you may have downloaded and installed each utilities you will wish to begin with RivaTuner first. )

Do not run any other applications and for those who just booted up let it method all of the startup programs and come back to idle Go ahead and open the RivaTuner application. In the Target Adapter section, find the Customize arrow. Click that and then go-to Hardware Monitoring, to see what your present core temperature(s) are at and write them down. As soon as you could have that go ahead and open up your ATI Tools. Stop the artifact scan in ATI tools and go back to RivaTuner. (If you are liquid cooled, ignore the following step): Click Customize Driver Settings, click System Settings, click the Fan tab, after which click Direct Fan Control. Move the slider to 100% and click Apply. If the fan becomes too loud, minimize the fan speed in modest increments until you discover a speed that you are comfy with. When that is done, click Save, and name the profile.

A desktop video card also referred to as graphics card, video adapter or graphic adapter can be a piece of hardware inside your laptop that is definitely accountable for generating what you see on your computer's screen. Many video cards nowadays have additional attributes for instance video capture, 3D scenes, 2D graphics, FireWire, TV-tuner adapter, light pen, and TV output as well as the capability to project images across a number of monitors.

Most desktop graphics cards are detachable from the mother board and have a port in the back to which the monitor cable connects. Some desktop video cards use the computer's RAM while other people are programmed to make use of their very own memory recognized as video memory. The high quality of graphic cards that computers are fitted with have a direct impact on the excellent of the monitor's output too because the end user's experience. One area exactly where the superior of video cards gains prominence is in gaming.

Next, in RivaTuner beneath Driver Settings click the Customize arrow then click System Settings. Click on the Overclocking tab, and click on Enable Driver-Level Overclocking. Click Save, and name the profile.

You'll start the overclocking by growing the Core Clock slider 10Mhz and click Apply, go back to your ATI Tools and click Scan for Artifacts again. Click Apply and go back to your ATI Tools and click Scan for Artifacts. If no artifacts appear again, repeat this approach until your satisfied or until you do commence to determine artifacts. Go back to RivaTuner and verify your present core temperature against your previous temperature threshold.

Many of today's laptop or computer games call for video cards that have a certain minimum level of functionality. Essentially the most prominent functionality needed of desktop graphics cards that can be utilised for gaming is recognized as 3D acceleration. Since several forms of gaming are characterized by rapidly moving and changing images, the graphic cards ought to have the capability to rapidly switch these photos in tandem with the altering flow of the game. The absence of a video card with 3D acceleration will typically outcome within the game not loading.

Now you are going to need to install 3DMark06 (if you haven't already), which is benchmarking utility (used to test 3D graphic performance). Go ahead install and run the program, and appear meticulously for artifacts and instabilities.

Is a firewire 800 laptop card adapter faster than USB 2.0 for pc to external hard drive transfers, etc.?

Im looking to upgrade the transfer speed to my LaCie external hard drive, but i only have USB 2.0, would adding a firewire 800 adaptor be faster than USB 2.0? thanks

¶ Absolutely;

the USB 2.0 Bus has a maximum bandwidth of 480Mbps
and Firewire 800 has a maximum bandwidth of 800Mbps

my suggestion would be go to e-SATA which depending on the PCMCIA slot can be SATA-I @ 1.5Gbps or SATA-II @ 3.0Gbps

there's two types of PCMCIA slots
the original wide card
and the newer narrower card which is basically laptop card equivalent of the desktop PCI-express slots
if your laptop has a PC-Express cardbus then you can use an e-SATA -II with a total bandwith capability of 3000Mbps / 3.0Gbps

3000 is a lot faster than 800,
even if you get a e-SATA-I @ 1500Mbps / 1.5Gbps
1500 is a lot faster than 800

for the same or similar cost you can add an e-SATA card and e-SATA enclosure for your external HDD and the external HDD will run as fast as if it were installed internally.
