I rented teh HD Video Essentials video to try and calibrate my LCD HDTV, but im confused. On contrast it says I should have Brightness on 50 (or halfway) but waht about the changes I made in brightness during the brightness calibration test? do I jsut not use those? also, im confused on how much contrast and brightness should be sued in calibrating contrast. It says it should be so its not clipping, adn that the colors should be dynamic or something, but what does that mean? I seriously spent 7 hours trying to calibrate this thing,and its not working. after I was done doing what I thought was right, I had about three sets of Calibrations I thought were waht teh video wanted me to do:

1. 70 Brightness
70 Contrast (this one seemed to even to be correct)
77 Color
0 Sharpness

2. 70 Britness
61 Contrast
70 color
0 Sharpness

3. 65 Britness
62 Contrast
Color 70
0 Sharpness.

I really dont know which is better. 65, 62 made things dark.

It all depends on what the range for your settings are. Contrast is the most difficult thing to set correctly because there are numerous things to look for. As far as what your settings are currently set at, there is no way to tell if they are currently set correctly since we are unable to evaluate it.

Well, the 65, 63 one makes the Dark Knight look dark (heh) when in dark palces. like, really dark. I did waht teh video said I thought it said to do, get it so teh Blacks adn whites dont clip. but the problem is there\s multiple setting shere they dont clip, so I dont know waht to do from tehre. the video isnt very good at explaining stuff.

Generally on a digital display I would say to set contrast as high as possible, so long as there aren't any undesirable effects like mentioned in http://www.avsforum.com/avs-vb/showthread.php?p=12471330#post12471330

When I rented and watched the settings section I noticed that they didn't thoroughly define clipping (maybe it's in another section). Basically for contrast clipping just means that beyond a point you won't be able to see any change in brightness. They try to show this in the demonstration by how at a low setting there is a change in brightness across the image and with high contrast the brightest part of the image ends up being the same shade. Some TVs behave that way and some TVs can be set to maximum contrast without any easily noticeable clipping.

So high Contrast is good? wahts teh highest i shoudl probaly go? 80? 90?

BTW: waht is white Crushing? when you cant tell teh White in teh scale from teh white in teh background (when using Test patterns.)

Generally crush and clip are similar. If you can't at all tell two different shades apart, that's a good-enough basic way to describe things.

As far as how high to set contrast, that's what patterns are for. They just provide a certain intended image and you can observe how different settings on your electronics affect the image. For a digital display the most basic thing to do is to make sure that you're not clipping below white with your contrast setting. Some displays will be fine with the contrast on max and others will need to use a lower setting. Hopefully the instructions for the pattern you're using explain what to look for to check for clipping or crush, or if your player is compatible and you're able to burn to DVD you could maybe use the link below to see how many bars the White Clipping Pattern flashes with different settings.

waht if the white is clipping (IE it becomes one with teh background color). Is that ok or is that bad? also, waht about setting Color? It said to match the blue in the Reference bar to that of the blue Rectangle they put over the bar, but Im not sure if they meant make it so they blend in with each other (meaning no lines telling them apart, also meaning the color is in the 70s or 80s, which seems high.) because No matter what it looks liek its the same color, but there are lines taht seperate them on lower color settings, adn teh blue gets darker.

waht teh waht meant liek taht, adn teh

What is the matter with you?

I didn't think of dyslexia, Damn. Sorry, Vesh Drown.

Also, while im doing teh contrast calibration test, I dont know if they say i should have the contrast way up or not. They just said turn brightness to 59, and out contrast way down. then increase contrast till you dont see clipping. but the problem is it stops clipping at a mid to low level, and I dont think thats right. Isnt 70 to above contrast better? It seemed to stop clipping at 60 and below.

on an LCD you want brightness as high as you can go without clipping and brightness as low as you can go while still getting 4% stim to be visibile.

Then you control the over lumanance with the backlight.

What they are saying about having a lower contrast setting being better is more geared toward CRT or Plasma where contrast literally controls the voltage to the phosphors.

you mean Contrast as high and Brightness as low right? also, waht is Stim?

er yeah contrast high, brightness low.

4% meaning 4% grey where 100% grey is qhite and 0% grey is black.

stim = stimulus.

There is a general movement away from using IRE since its roots are in analog and digital values need to be converted into IRE taking into account the analog signaling standard in use. So just saying 4% stimulus is much simpler than saying 4IRE where that may be above or below black depending on weather or not the standard uses a 7.5 IRE black pedastal. If you didn't understand any of that don't worry, just say 10%, 4% 100% instead of 10 IRE, 4IRE, 100 IRE.
