The PC will either have a full size or mini HDMI style of video output connector or maybe a DVI connector that can also be used with HDMI displays with a simple adapter cable.
Yes
DVI
HDMI splitter is compatible with Digital Audio. HDMI cables and splitters are carrying audio and video signals without any data loss or downgrading quality.
There are multiple converters and cables that are compatible with both HDMI and VGA, which is some sort of an adapter to an adapter. I do not know how well these products work together.
HDMI capable laptops are sold directly from most major manufacturers such as Apple, Acer, Asus, Dell, Lenovo, and HP. In addition electronics stores and online stores such as Amazon offer HDMI capable laptops.
It has to come with your video card.. normally the older models won't have Hdmi ports
No. Consumer VCRs are not compatible.
with the compatible cables like HDMI...
Yes they are. Bluray players have an HDMI output for their high definition signal output as well as analog connections for compatibility with displays that are not HDMI compatible.
You have to get an HDMI cable with an HDMI compatible TV. Then split - screen should work.
Not explicitly. The dreamcast did support VGA output through an optional adapter, and by interfacing that adapter with an additional VGA to HDMI adapter, HDMI-compatible output can be achieved.
HDMI cables are used as digital video and data links between video sources and televisions. HDMI is compatible with DVI interfaces so if the laptop has a DVI output, a DVI to HDMI cable can be used. If the laptop does not have HDMI or DVI, then there is no way to connect the VGA output to an HDMI input. There are several USB based video displays that can be purchased to connect to the laptop. The display can be used as a copy of the internal screen or it can extend the desktop across both screens. Select a display port that has either DVI or HDMI outputs.
