Another interesting article on HDMI cable.

Spend more on Cables?

it's very simple, to proof it one and for all, just take photo of the image of of the TV screen.. like they do when comparing projector A and projector B image quality.

cos for video quality , no need the "golden eyes" to see the diff, photo shots with the same room conditions and camera settings and pause at certain scenes can already proof if there is difference or not.
(unlike those mythical golden ears elites when comparing Subwoofer/amp/speaker/CD player)

so far I still haven't come across any professional website/magazine who review the HDMI cables this way (they seem to only review it with the digital signal analyzer for signal integrity)

which is surprising cos they do so this way (image capture) with different projectors to analyze the whole image quality down until sub pixel level quality (like those out of aligment subpixels and even screen door effect)..
so why is that?

so not worth spending on cables?

Yep, first time I read about those HDMI details.

Depends on your hardware and budget

I just got a China brand HDMI 1.3b cable for my NMT. Comparing with the free HDMI cable came along with my pioneer dvd player, the picture is now slightly brighter then before.

if china HDMI1.3b vs Monster cable, I wonder if it's even more "clear"

Not too sure about that

Seriously I am now seeing more of the "rainbow" effect on 720p movies which is not seen before. However with 1080p movies there is no "rainbow" effect

wah..rainbow.. you using DLP ar?

DLP with low speed color wheel kua

Dunno the technical terms for it but it is those rainbow like vertical lines due to compression lost.

Just saw at Carrefour Kepong a 2m HDMI cable for only RM23.50.

ok,below are 2 screenshot taken using 2 different HDMI cables,one "MP Acoustic( RM35 )" and the other " Panasonic RP-CDHG15 ( RM170,maybe kena potong:P)".Both picture taken with same camera/setting/time/place/scene,original pic without processing,reduce size in CS3 for posting.

1)


2)


i'm sure there're some kind of compression and lost in quality during the process of "reduce size,web hosting" but both using excactly same methob for above action,no a proper serious comparison,just corious to know the result,guess which one by which cable? Or no different at all?

looks like exposure levels/lighting conditions from camera's each shot are different... (did you use the SOP** i.e. "graycard" and manual white balance, shot in RAW)

could say that the top one is more white balanced (bottom photo, lefthand blue screen side looks white washed)..
but then again the the bottom one can see more details near the right side, on the darker feathers.. so how?

maybe a rm1k HDMI cable would have best from both images?




"The single WhiBal card is light Gray, certified to recommended Luminance level of L* = ~75, which is optimum for use in all RAW converters.

Having a "GrayCard" reference is the best assurance that the digital pictures that you capture will have the ability to be properly White Balanced. Only with a proper White Balance can you be ensured of proper and accurate color, regardless of lighting conditions. Unlike your eyes, a digital camera does not automatically see whites as white. It sees the color of the light reflected from it, hence blue-ish in Daylight and Orange-ish in incandescent lighting. By photographing a Gray Card reference for each lighting situation that you are in, you are assured of being able to achieve a proper White Balance for all of your pictures.The Gray Card reference picture can be used with today's software to balance the color casts that various lighting conditions produce with all digital cameras. The best method to properly White Balance your digital pictures is by using a Gray Card properly and shooting RAW. RAW Conversion Software such as Adobe Camera Raw and RawShooter can then perfectly adjust all the captures that were shot under the same lighting conditions."

thanks ar188,i'm using the same AE900 like urs

Both pics taken without grey card but with 40D,mount on tripod,shoot in RAW at iso100,F4.5,speed < 1sec and AWB.Tripod was not move at same location and lighting condition everything same.I din adjust the WB when open in CS3,just cropped and resize.I found both pics the white part wash out.One thing i found quite hard is when u try to pause the scene(maybe only in PS3?),the still image is not "sharp" compare to the when the playback the movie.That lost a lot of details from the original pics.

For me,the difference in both pics is on the 2nd pic,the brightness looks a bit high,can see more details on the black portion and the contrast is good.The advantage is even the brightness is higher,the black portion still doesnt looks too "grey",almost same compare to 1st pic.The wash out on the "white" portion maybe becos of the contrast was setting a bit too high.( i'm using "cinema 3",contrast at +10 and brightness at -8 ). Bro arr188,mind to share which mode u normally use and what's the setting? U got Happy Feet US version too?

However,the different only can be seen after taking the pics and do comparison like above.When in movie playback i cant really tell the different.Hopefully can pinjam someone 1k HDMI cable?

below is another pic taken with Pana HDMI,i adjust WB a bit with the RAW pic

myqd.. off topic, our AE900 can accomodate any firmware updates ar? hehe!

hehe,our panny like old men oledi,still can makan,but never can take too spicy 1080p's food U can try to hack the firmware to enable pure 1080p (not downscale to 720p),make sure u let me know only,otherwise panny jepun tau sure they are at ur door step tomolo

i can c that the contrast bit too strong on top part and below pic looks more natural. same length for both HDMI cables?

In terms of signal i believe there's not much difference right?..i mean..it's digital signal '101010101'..but if we're talking about the built...then probably got difference..

Simple way of looking at it, the newer version of HDMI cable (v1.3a & b) is all about faster transfer speed plus other stuff.

not forgetting to support deep colour too.
