Generally, the answer is no: the sound output will be directed either to the "speaker out" jack or the HDMI jack. There may be some computers in which you can make both active at the same time but I am not aware of any at the moment.
I would suspect that the most likely circumstance in which you could manage this would be if you had a sound card installed in your computer rather than using the integrated audio that came with the computer. Some sound cards have both HDMI and "speaker out" jacks and both may be active at the same time, thus providing the functionality that you seek.
Usually yes. BenQ is a computer monitor manufacturer and they make various Computer Monitors with varying feature sets. Most of their monitors contain HDMI ports but not all of them do. A PS3 also contains an HDMI port. If your monitor contains the same type of port as the PS3 then the monitor may be connected to the PS3 via an HDMI cable. However, if you want to play the PS3 with sound, then the monitor must either have built-in speakers, or have a headphone or audio-out jack that you can plug speakers or headphones into. Not all computer screens have these features, so you should check that they support these features before you purchase the monitor.
HDMI is not the same as SCART. HDMI is digital interface while SCART is analogue.
at the same time
No, HDMI converters and HDMI extenders are not the same. An HDMI converter is designed to change the format of the HDMI signal, allowing it to be compatible with different types of connections, such as converting HDMI to VGA or DisplayPort. In contrast, an HDMI extender is used to extend the distance over which an HDMI signal can travel, typically using Ethernet cables or other means to maintain signal quality over longer distances.
Yes all hdmi cables are the same
you can both play but you will see each others worlds
DVI cables and HDMI carry the same video quality, HDMI however can pass audio.
Playing PS3 on 2 screens is not possible since the PS3 only has one HDMI output. It is possible to clone the screen to another TV if your TV allows that. Playing a PS3 on 2 screens separated requires an extra PS3 and a console link.
All HDMI cables are manufactured to the same standards. If an HDMI cable can physically connect to a device, then it should be compatible. This applies to different variants of Playstations as well as video players.
same thing
No, all HDMI cables are created equal and will give you the same high-definition quality regardless of price and there are many inexpensive HDMI cables; there is no reason to pay a lot for an HDMI cable.
Yes. Hdmi cables are all the same. They are not console specific
