It seems like it is fairly common for users to install the display adapter but then get no display or functionality on their screen. There are quite a few things that can cause this and the user manuals can bet a little bit vague as far as troubleshooting. There are a few main reasons this occurs. The most common is that you need to update the display adapter driver. It could also be due to screen settings or resolution settings. It is also possible that your primary graphics car will need to be updated. Sometimes your computer just needs a reboot. All of these cases are common with the video out functions of the docking station products as well so the same fixes are applicable.
Installing an outdated display adapter driver is by far the most common reason that users are not getting a display out of their adapter. The website www.j5create.com always has the latest driver versions available and tells you the version number on the support page. Check your driver version in control panel>programs and features to cross reference which driver version you have installed. If your version does not match the version on the site then it is very likely that you will need to update it. This is a fairly simple process that anyone can do but, depending on your system, it can be time consuming. The first thing you want to do is disconnect you adapter from your computer. Then you will want to uninstall your current driver version and restart your computer. Once your computer has rebooted, download and install the latest version from j5create.com. It is located under the support and services tab. Once the installation has completed you must restart your computer. It is prudent to note that sometimes on windows xp and windows vista it will not prompt you to restart when the installation is complete but this is a necessary step none the less. Once your computer has fully rebooted and come back to the desktop you may reconnect the adapter to the machine. Your computer should notify you that it is installing device driver software upon connection. Some computers will require another reboot once this step has completed, usually windows xp and vista machines. After this step has completed you should see your screen activate and show a blank desktop background. Do not be alarmed that there are no icons or taskbars on this screen. This is how it is supposed to be. The screen is running as an extension and can be utilized by dragging windows from your main display onto the secondary display. J5create has instructional videos on how to use these devices in this way on youtube. There will be links to such videos at the bottom of this article. The biggest thing with this issue is making sure that your adapter is disconnected throughout the entire installation process, this is where most people run into trouble.
Sometimes when connecting additional screens, especially big screen TVs, the device will be working properly but you would never know it because the settings on the computer are preventing it from displaying properly. The biggest issue here is resolution. Most TV screens operate at a native resolution of 1920 x 1080 pixels. Because of this they often cannot display at lower reslutions which alot of computer set the too at first. First of all you will want to make sure your TV's is not net to mirror your main computer display. When it is set to mirror it is forced to use the resolution of the main screen which typically, especially when connected to a laptop, is far too low to display properly. In your screen resolution right click desktop>screen resolution/properties/personalize depending on your version of windows) set the monitor to extend your windows desktop and set the resolution as high as with will go, typically to 1920 x 1080. This should fix that issue and bring up the display on your TV or monitor.
If your computer is a little bit older, running windows xp or vista, or if you have tried everything mentioned above with no results, it is likely that you will need to update your primary graphics card driver. To do this you will simply navigate to control panel>system>device manager and then open up the display adapters tab. This should display your primary graphics card. Right click on it and select update driver software. Tell it to search automatically and then let it run it's course. This process can take several minutes so do not be alarmed if it is taking a while. Once it has completed you will need to restart your computer and once it has finished rebooting you should have you display up and running.
