I got my hls-5687w calibrated and i've noticed that the contrast/brightness is different for each of my components (i.e. dvr, xbox, hd dvd player)

Meaning....my xbox's output is a little darker than my dvr...and my xbox is darker than my xbox

How do i fix this?

Greetings

Calibrated as in calibrated by yourself or a professional guy?

Are all signals being sent to the TV directly or through a switcher of some form ... ?

Ability to individually compensate depends on this ...

Professionally calibrated for $300

the signals are being sent directly to the TV.

Then it comes down to what was asked for in terms of calibration ... by the input? For stuff he wasn't aware of or not asked for ...

If you have a test disc ... you can usually put it into the xbox to set brightness and contrast and stuff ... but that would only apply for DVD played on the game box ... not the games themselves. Games that come in 720p flavor might need unique settings versus 1080i/p flavors. Need a signal generator to set that part up ... and the TV may not actually permit multiple settings in the SM .

Sad thing here is that game companies ... although supposed to develop games on calibrated displays, don't always do so. As a result ... you get variance from game to game ... too dark ... too light ... just like cable TV/satellite.

Well the guy only had a component signal generator, but he said since my tv upconverts everything to 1080p, that the grayscale settings will apply to everything at 1080i/p

I can visibily tell that my dvd is much darker than my cable box...i am forced up my brightness in my user controls

seems like this is a flaw in the whole ISF calibration thing....u can use a signal generator to do a consistant signal...but that doesn't account for the actual device that's hooked up....like it's clear my dvd is darker than my dvr....kinda makes me question the real benefit if ISF calibration

it's only beneficial if my components generate the same signal as the signal generator

he set my orange based on his signal generator...but the bottom line is orange is variable based on the component that is outputting the orange

i'm kinda bummed out

On your television, brightness and contrast need to be individually set for each input type and scanrate that you use.

A good calibrator will run through each device that you're using and make further adjustments as necessary after the signal generator is put away.

So....what do i do now? all i really want is a dvd that lets me set the contrast and brightness. I'm not paying some other isf "specialist" to do this.

The flaw is you hired someone who does not know what they are doing. These displays have idiosyncrasies with various source types (YCbCr, RGB...). This needs to be considered in the setup and calibration.

I used my star wars dvds, which have the THX calibration on them

my brightness went from 33 (set by isf guy) to 53 on my hd dvd player

my brightness went from 33 (set by isf guy) to 45 on my xbox

pretty significant difference

i could visually tell the image was too dark.

remind me why i spent $300 for an ISF certified calibrationist?

Like in any profession, practitioners vary in skill and discipline. You should call your calibrator back and work it out. If he has integrity, cares about his customers, and values his reputation, he will be interested in getting this right. Did you ask for references?

There are differences in equipment too. My hddvd player outputs darker than both my 360 AND my HDDVR. I have all of my equipment running through my receiver and then to my TV. All HDMI. My brightness is set to 36 when I play my hddvd player, but using HDNET's test pattern or my 360 with DVE, I have to adjust it down to 26 for it to be accurate. It's just the nature of the best (so to speak).

And the calibrator should have explained this to his customer.

HDNET test pattern? how can i git ahold of that? I have the HDNET channel.

I agree completely with this. Any professional calibrator worth his salt will come back and correct this to your satisfaction. In addition, source components MUST be accounted for when calibrating individual inputs. We don't watch signal generators!
I would demand that he return to correct his poor job. Make sure he remeasures gray scale after adjusting contrast and brightness. They do interact on this display.

Keep in mind, the Sammy HL-S5687 has a multitude of adjustments that can deliver a very accurate image. I have a pretty good feeling that this individual may not know how to perform these adjustments. i.e. color decoder, color gamut, wobulation, index delay... This display calibrates differently than most. The end result should be excellent.

did he print out results from the Sencore machine?
