Benefits or advantages
Unlike direct output from speakers, HDMI® provides high clarity of sounds and video. In addition, it reduces the costs of purchasing additional sound system by making use of the HDMI® cable to attach to a music system or TV set. The extra advantage is the easy installation procedure when making connections. It is a plug and play device, thus the user does not have to go through the manual to learn the connection procedures.
In case of power fluctuations, the laptop or the device connected to it or both in some cases can short circuit. Power supply via the HDMI® cable is direct, which raises concern on devices short circuiting in case of power spikes.
Different systems have altered sound quality and thus the sound clarity produced may not be of the expected performance.
The costs of acquiring the cable is high and in most cases some users would prefer to, just get the laptop without the cable itself.
The laptop is also likely to over heat as the HDMI® cable uses extra heat meaning more heat is generated by the laptop to support the connection. The major arising issue is the differentiation between two displays when set to clone mode by the ATI™ driver. The ATI™ displays them as two branches in the same hierarchy. In addition, the 570 HDMI® does not support a full 1080p (1,080 horizontal scan lines) in the real sense of the word.
To solve some of the arising issues, set the receiver to another input such as the radio the PC that will detect the primary monitor as not connected, just as if the cable was unplugged when the output feeds through the receiver set as the primary display. It is possible for clone display to work if it expects the primary display to, always be connected and in use while in the setup, it may not be raising problems of driver compatibility.
Try setting the output connected directly to the TV as the primary as the PC should see that as connected so long as the TV is on (possibly even if off/in standby depends on the TV), even if the TV is not actually set to that input, might solve your issue if I'm guessing correctly.
Using the VGA cable as an option is a good idea in reducing the extra power generated and the possibilities of short circuiting in case of power fluctuations.
