HDMI Output in Lenovo® ThinkCentre A70z All-In-One PC
Lenovo ThinkCentre A70z all-in-one launched from Lenovo is designed to enhance the response speed. The screen is about 19” wide promising excellent gaming and movie experience. It features high definition audio and video effects along with the multimedia technology. The OS set in by default is the Microsoft Windows 7 Professional. HDMI is a means of interface to control two devices with a single remote, provided both the devices are connected to each other via a strong cable. If the AV port of the TV, play station is inappropriate, the vital sound or video will not be produced. If the NMD signal used to carry the digital data in the uncompressed format is found defective; the HDMI output will not produce the efficient result. A number of issues concerning the image and sound quality have to be dealt carefully for efficient data reception at the other end device.
- Defective cables
- Poor image clarity
- Sound mismatch
The HDMI output of Lenovo ThinkCentre A70z all-in-one PC is connected to the TV, play station or set top boxes with the help of a cable similar to the USB connector, DVI connector or a DB8 connector. The connector is the physical link that connects the two devices. If the cable is faulty, proper data transfer will be hindered. This will not produce the desired video clip at the receiver end. Hence, make sure the cable is effective and properly insulated before performing the connectivity.
Poor image clarity
The data transmitted and received might be dissimilar, in case the signal strength supported by the two devices is diverse. Then the image quality rendered will not match with the transmitted image. It may also cause improper image rendering where the alignment, sequence and clarity of the image will be compromised. If the signal strength is not uniform, it can cause image over-scaling, zooming etc.
The audio-video synchronization at the transmitter and receiver will be different if the signal transmission or reception is delayed. If the audio and video carrier signal frequencies are delivered at the receiver ends at different instants, the sound and picture will suffer from mismatch. The Lenovo ThinkCentre A70z all-in-one PC supports high definition super sonic effects. Hence if the cable fails to render the sound quality with the exact signal strength, it will be unpleasant to hear.
