10 bit is the chip processing used for colours.. Some higher end lcd like Eizo used 12bit processing per colour. The lcd panel itself is still 8bit for each colour or 256 shades capable 256x256x256= 16.7 million. The processing of colours will in theory add more vibrance to certain images being displayed.

Most lcd tv are 1366x768 resolution .. except for the high end models of 37 inch and above that are able to output 1920x1080 resolution

6 bit panel commonly known as TN screen which doesnt offer very wide viewing angles and its actually able to produce 256colors only, but manufacturers found some ways to dither the colors that they can display up to 16.2m color which is pretty close to 16.7m colors on typical 8 bit panel (honestly thats what they claimed, who knows).
6 bit panel only produce 64 shades for each colour, three colours ... 64x64x64= 262k of colours not 256...It is using a dithering method which combines adjacent pixels to simulate the desired shade to form 16.2million

Btw, i'm just curious whether a 7600GT would be able to support
1) a single 30" OR
7600GT should support at least one 30 inch 2560x1600 display, some 7600GT come with 2 DL-DVI so you will be able to run 2 30 inchers in 2d.

Dell will be releasing new 3007wfp-HC just for additional info, get rid of stock maybe or more likely sell together with the newer model at a premium.

30 inch has a tighter pixel pitch 0.25mm and 0.27mm on 2407. (4Mpixels on 30 inch, 2.3Mpixels on the 24.) So the human eye perception differs from one person to another.. but because of the smaller pixel pitch u will have to sit close on a 3007 when compared 2407 for the same pixel perception. If you have very good near sighted perception 30/24 will not make that much of a difference. Bigger screen/more pixels is always better.. with that said for one 3007 you can get two 2407

Does anyone know how to link 4 lcd screen into a single screen and where to buy such hardware? I been searching a few local computer shops here in Kota Kinabalu and none of them got such hardware or software to do it.

I have searched a lot on the net and the most closes hardware is Matrox, which could split the signal into 3 screens only as 1 BIG screen. I have asked a lot of local computer shop and none of them knows how to do it nor have any idea what am I saying.

I would like to use 4 lcd screen, and it should look something like this:
I am not to sure myself if it is just a software to do it or do I need a special hardware  sad.gif
Me, borned & raised in KK..
For 2d desktop use, or 3d app/movie watching

Matrox TH2Go supports only 3 monitors, DH2Go only 2

You have many options (Expensive to cheap) ..assuming 1 display is 1280x1024;
1. 2x2 display or one 2560x2048 display in Windows....2 Matrox DH2Go and one Nvidia/ATI ..Quadro FX/FireGL with Genlock&FrameLock function... ...no problem with movie/2d/3d in all monitors. All analog solution(or mostly)

2. 4x1 displays...or one 5120x1024 display.. One TH2Go and one Nvidia/ATI ..Quadro FX/FireGL with Genlock&FrameLock function ...no problems with movie/2d/3d in all monitors. All analog solution

3....cheapest... 2x2 display or two 2560x1024 stacked or 4 individual 1280x1024 display in Windows.... Any 2 pci-e/agp/pci graphic cards. (but some graphic card dont play nice with each other).. (no problems in 2d.. movie only with selected players..like Apple quick time player) in all monitors...3d app only in the primary monitor. Best quality if you have 4 dvi output.

Ultramon software for desktop/wallpaper setting

Many other combinations.. for preview..please see my workstation setup (you tube) in Hardware Q&A

And for 10.8Mpixels displays

One thing u will have to watch for if using 7600GT/GS, is this chipset/card does not have enough horse power/sofware quirk... if you indent to power direct-x app. in windowed mode on a 2d display desktop mode of 4MPixels displays (3MP and below shoud be fine).... No problem in full 3d mode..not windowed... My 8800GTX has no problem thou. Not a problem for those that dont used more than 1920x1200 displays

btw, what is GTG(gray-to-gray) mean??
Time taken for 50% of 3 subpixel (one pixel) twisted to 100%/0% to back to 50% (same state as before). That would be at 45 degrees to 90/0 degrees to back to 45%....polarization of light plane.... Black to White to Black ,...in theory ..should be 2x GTG...

b.t.w. human brains usually dont register/cannot perceive differences in time below 16 to 20ms (actual .... not as quoted by lcd manufacturers)

U means for ur GC or 7600GT?
I have 3 7600GS..2 with ddr2 one with ddr3 all at default 500MHz for gpu...which I roughly gauge slight deficit in performance compared to GT... that and I do own one 8800gtx.

sorry asking a noob question here.
I still cant figure it out tat dell 2407wft height adjustment...

i manage to find a button behind the stand but i cant move up or down..
pls help thanks..
the oblong button on the stand is to lock the stand at the lowest position... to release apply additional pressure down on the monitor,,before pressing the button will release the monitor.. at least on some stand reversion...that are at least 2.. 1st one was easier to release.. manually push monitor up/down for height adjustment.

Hi, i have problem with my samsung 15' lcd monitor, the monitor colour just fade, and everything just went black. Still able to see, but blurish and have to move really close only can see a blurish image. Should i sent to samsung service center for a checkup? how much they usually charge?
mostly defective analog vga cable... 15 inch..likely builtin? harder to replace...

..tats the max tat i cant rotate the screen? hmm..? wonder how u did it?
mind to teach me? coz it seems i do not have enough space for my screen to rotare vertically
For 2407wfp with the ori. stand you cant rotate the monitor while the screen is at verticle position without hitting the table or stand.. logic would have it that u would have to tilt the monitor backward...screen facing the celing.. to the max..before u can rotate 90 degrees... then tilt the monitor back to the position u desire.

1080p on dvi/vga at 1:1 with 2407wfp A04 still have problems... screen splitting.. on and off to solve... but maybe wait for A05?

yes, at loss now
4 pins are for analog signal.. which is carried by the graphic card (dvi-i) and the monitor's dvi input (dvi-d) is only for digital... therefore do not require the extra 4 pins..

Therefore getting a 24 pin dual link-dvi or 18pin single link-dvi (recomended and cheaper) cable for your monitor will do...

presently i am using my lcd samsung 932b vga port for computer, so got a extra DVI port, so i thought of using it for my DVD player to hook up with the lcd( DVD player - it's comes with a video VGA output ) so no need to switch on the computer or plug in and out  the vga cable, i was looking for a DVI to VGA adaptor, but the adaptor on the DVI side got this extra 4 pin , but my lcd DVI port didn't have the extra four holes, so i was thinking of using some tools to take out the 4 pins from the adaptor? can work ?
cannot shakehead.gif ... DVI is digital...vga is analog... your dvi input on your monitor handles digital only... I suggest you use sl-dvi (pure digital ... not vga cable with a dvi-i to vga adapter)cable to connect to your computer .... and the vga input to your dvd player...

That is assuming that you have a discret vga graphic card with dvi output... If not you have to purchase a vga switch (RM 15 or so ...cheapest, manual) to switch between your vga source...

dvi-i to vga adapter is purely a analog signal cabling by pass adapter.. by routing the 4 pins and utilizing some of the other dvi pins to pass on the analog vga signal...it does not magically convert analog to digital signal.
U can say the extra 4 pins is security feature to stop uninformed user like you from inserting an analog signal to the dvi-d port on the monitor which may damage your monitor.

document??? if ur using lots of spreadsheet....trust me widescreen helps. ALOT!

but if ur gonna be opening 2 documents at the same time and making comparisons, dual screens helps even more. im using dual screens in the office and i make lots of comparisons and also spreadsheet like documents (SPSS data etc).

but if u ask me to choose between wide and non wide....my vote goes to wide.
19/17inch 4:3 has more pixels than at 16:10 wide... go for the cheap 22 inch 1680x1050
