How to troubleshoot the External Display or a TV connected to theComputer

If you’ve connected an External Display to the Computer and you’re getting the symptoms “Television is not recognized” or “Unable to activate TV-out”, what can you do? No Ideassss??
No problem, because earlier we too had no ideas about this issue. The main reason for this issue is improper Display Settings, a Computer without a TV-Output Port, a cable requiring replacement, an outdated Graphics Driver or any other factors.
Okay, let’s come to the point. If you want to resolve the issue and you don’t know what to do. It’s okay, just follow the following steps as exactly mentioned to resolve the issue.
Solution:
To resolve most problems associated with TV-out activation, use the following steps to enable TV-out from the Intel® graphics driver tab:



1.    First, it is required to shut down and turn OFF the Computer.
2.    If you’ve not connected the TV-Out Cable, connect it now.
3.    Then, power on the TV.
4.    Thereafter, power the Computer on.
5.    Now, you have to open the Intel Graphics Driver window.
a)    Go to the Control Panel from the Start Button.
b)    Then, double click on the Display icon.
c)    Now, select the Settings tab.
d)    Then, click the Advanced Tab.
e)    After that, select the Intel® Extreme Graphics tab or the Intel® Graphics Media Accelerator Driver tab
6.    If you can see the display as shown in the image 1, you can skip the 10th and 11th steps and select the Television as the Single and Primary Device under Display Devices fro the Intel(R) Graphics Media Accelerator Driver.
7.    Then, click on Apply and then click on OK.



8.    At the same time, if you don’t view the image 1 and view the second image or the third image, you can follow the 10th and 11th steps.
9.    The latest version of the Graphics Driver displays a different screen as shown in the second and the third image.
10.    Remember, you have to skip this session if you’re viewing the first image. If you’re using an HDMI to connect the External Display (TV) or DVI, it will be recognized as a “Digital Television” as show in the second image. Now, you have to confirm the Operating Mode if it is a Single Display and Digital Television is the Display Selection.
11.    Then click on Apply and then on OK.
12.    If you’re using a newer Driver, you have to confirm if the Television is selected from the Display drop down menu.
Note : if you’re not able to resolve the issue with the above provided steps, please follow the following instructions.
•    First, try to reseat the both ends of the Television cable.
•    You can use a replacement TV cable. Remember, that should be the same kind of the connectors.



•    Consider if your Computer has no TV-output port and has VGA Port, the TV-Out may or may not be supported by the Computer.
•    Therefore, check the User Guide of the Computer.
•    At the same time, if you’re using an External Monitor, you’ve to shut down and power OFF the Computer.
•    Unplug the Monitor, let the TV be connected to the Computer and then power ON the Computer.
•    You may also try adjusting the Desktop screen resolution to 1024 x 768 or below.
•    You can also check if the Computer is shipped with BIOS settings to enable TV-out during bootup.

New Micro battery, power packed for high performance

For a size of a few millimetres, the new micro-batteries are powerful enough to jump start a car battery and then quickly charge the cell phone. Researchers from the University of Illinois have developed the micro batteries which can be used to drive compact electronic devices and new applications for radio communications. The micro batteries are so good that they can even out power the super capacitors. The results were published in ‘Nature Communications’ in the April 16 issue. The micro batteries have energy and power and with the researchers tweaking the structure of the micro batteries a little bit, its use can be for wide range applications.

The high performance of the micro battery is based on its 3-dimensional micro-structure. Based on the design of fast charging cathode by Professor Paul Braun’s group, researchers developed the matching anode and integrated it with the fast charging cathode at a micro-scale and made a complete battery with high performance. These batteries cou…
