Yes, you can send video & audio via HDMI from notebook to HDTV. Just settings in your control panel.

Comments from PCB designer for LCD;

Critic about poor quality & cheap HDMI cable in the market now without HDMI specification compliance!!!
Especially china-made & even some Monster cable also without HDMI compliance .


As we know for our every PCB design must pass the imedance test in order to get the compliance approval or certificate.

Impedance Control is very important in HDMI signal, from the Processor to the Source including the cable,
bcs it is very High speed digital intense data rates which are traveling through the cable. (4pair of data clock must be 100ohm impedance)

Impedance, in particular, becomes a really important concern any time the cable length is more than about a quarter of the signal wavelength, and becomes increasingly important as the cable length becomes a greater and greater multiple of that wavelength. The signal wavelength, for one of the color channels of a 1080p HDMI signal, is about 16 inches2, making the quarter-wave a mere four inches--so impedance is an enormous consideration in getting HDMI signals to propagate along an HDMI cable without serious degradation.
There are a few considerations that start to cause real trouble:

1. Time: electricity doesn't travel instantaneously. It travels at something approaching the speed of light, and exactly how fast it travels depends upon the insulating material surrounding the wire. As the composition and density of that insulation changes from point to point along the wire, the speed of travel changes.
2. Resistance: electricity burns up in wire and turns into heat.
3. Skin effect: higher frequencies travel primarily on the outside of a wire, while lower frequencies use more of the wire's depth; this means that higher frequencies face more resistance, and are burned up more rapidly, than lower frequencies.
4. Capacitance: some of the energy of the signal gets stored in the wire by a principle known as "capacitance," rather than being delivered immediately to the destination. This smears out the signal relative to time, making changes in voltage appear less sudden at the far end of the wire than they were at the source. This phenomenon is frequency-dependent, with higher frequencies being more strongly affected.
5. Impedance: if the characteristic impedance of the cable doesn't match the impedance of the source and load circuits, the impedance mismatch will cause portions of the signal to be reflected back and forth in the cable. The same is true for variations in impedance from point to point within the cable.
6. Crosstalk: when signals are run in parallel over a distance, the signal in one wire will induce a similar signal in another, causing interference.
7. Inductance: just as capacitance smears out changes in voltage, inductance--the relationship between a current flow and an induced electromagnetic field around that flow--smears out changes in the rate of current flow over time.

Poor impedance control cable can affect the data/clock/time/ loss in every micro second signal change.

Good HDMI cable should be tested with critical parameters includes Impedance, Attentuation, Crosstalk & Skew in "Eye-Pattern" technique.

monster cable rocks!!!
u can get pretty good bargain in evilBay

Tesco Technika RM19.90 HDMI also rocks! Boleh di dapati di seluruh Malaysia!
If on offer it is only RM15!

All I know is, in high resolution Hi Fi system, different cables sometime do sounded differently. In fact, many people do hear a difference. Just because we do not know the reason why does not necessarily mean that should not happen.

Therefore I am open minded about this HDMI thing. But I do not want to open up a can of worm so never bother comparing whether this is ore there isn't any difference.

This topic has been discussed to death. The general view is that any HDMI cable will either work or it doesn't and it does not add or take away anything from the digital data regardless of the cost as long as it works. There is a difference in the physical aspect, an expensive one will probably look much better and MAY last longer than the cheaper variety with frequent handling and pluging in and out. Just my view.

Poor HDMI cable will loss some colour bit rate (colour deep), dot pixel missing, & loss of sharpness.
I don't think you can see thru by yr eye in LCD TV, unless you have Color Spectrum Analyzer equipment.

i had test BELDEN HD2003 & HD2001 is the best in term of colour deep.
Anyone who interested, u can PM me for detail.

TQ.

I also fall into the camp of people that been branded "something loose inside the skull" as I "believe" there is something out there by "using" the branded, expensive, designer HDMI that cost many time more than those Tesco one.
I do not dare to comment on "there is improvement" as I do not want to open a can of worm, but I just "dare" to say that "I pray I did not spent my hard-earn foolishly" but anyway, its my money.
Also, I am not a saint, therefore I spent my money my way, not the "charity" way......

I always use the word "difference" and never use the word "expensive sounded better". No such thing.

As for whether you will hear a difference or not, it is best to go listen to a high resolution setup yourself. NOTE: It must be a high resolution setup because with lower end resolution setup, there is not likely to be any difference.

And if you have done that with an open mind, the majority will hear some differences in sound.

Here is some test done by audioholics & their conclusion.

have you tested tesco house brand hdmi cable?

yes but most of these differences are discussed with regards to analog cables

Anyone know where can get good quality long HDMI cable (around 12 to 14 meter 22AWG) at cheap price within M'sia?

Are HDMI optical cable?

He means analog signal as in waveform such as RCA and speaker output. HDMI is using digital signal as interpreting peak and null as 1 and 0.

Cheapest HDMI cable just get from Monoprice. For the 22AWG at 40ft is around RM 100 not including shipping.

Try monoprice, good quality with reasonable price.

I'm planning to get from there too, just wanna know if I could get it within M'sia, then I can save the shipping cost

omg

just a refresher course on the current thinking about HDMI

C|Net 2011 HDMI article

hello there.

where can i get cheap 6-8m hdmi cable ?

want to connect my pc to my lcd tho.
