how do you adjust gamma? I'm at a low 1.6-1.9 depending on measurements...does my static gamma control in my user settings help gamma overall? and does it affect any other settings...

everything else looks pretty good after calibrating...but i want to address the gamma number...i'll add a calibration file soon.

so static gamma adjustments don't help overall gamma...i guess i will live with 1.69 gamma...damn, grayscale and color temp tracking look great...oh well...

Sometimes lowering the contrast will improve the gamma.

eventhough i'm at 50ftL for brightness...should i bring contrast further down?

LCD should be between 50-60 ftL right?

That's far too bright if you're viewing in a dark room, I'd have it calibrated somewhere between 24-30fL. (80-103cd/m2)

i have a slightly lit room...Tom Huffman states LCDs should be 50-60, but plasmas should be 30-40...why are you stating it should be less? but if that helps, i'm there!

SMPTE recommendations. (But assumes total light control and controlled room environment)

Regards

which is smpte recommendation, Tom's 50-60 or Andrew's 24-30?

i guess it is subjective then...i'll play with it a little bit more when i get less light from outside tonight.

Greetings

The low numbers are the smpte range.

thanks again...wonder where Tom got his numbers from then...again, this is an LCD set

I think the higher brightness for LCD compensates in some ways for their higher black level v other technologies.

Well, depending on the display, 50-60fL may maximise its contrast ratio (difference between how bright white is and how dark black is) which is fine, but in a darkened room I find anything over ~30fL to be painfully bright. (even 30fL is a bit on the bright side with an LCD in my opinion)

While there are specs on display brightness, in the end it's all about what you prefer really. Many of us in the calibration section prefer to be as close to spec as possible.

by the way I'm trying to nail down the calibration on a very similiar display so please share any fixes you find on gamma.

Could you please post the smpte standard ranges for the different displays (in dark settings)? I've seen a couple different resources quote 35 ftL for LCD.

i have a slightly lit room...Tom Huffman states LCDs should be 50-60, but plasmas should be 30-40...why are you stating it should be less? but if that helps, i'm there!These were intended as ballpark recommendations only and largely motivated out of a desire to stop people from using white clipping as a method for setting peak output (for LCDs especially). Many LCDs do not clip even when the contrast is set at 100% where the peak output can easily reach 100 fL or even higher. 50 fL is a more reasonable setting. If you watch in a totally light-controlled environment, then lower is certainly better, but what causes eye-strain will vary greatly from person to person.

My guess is that most of us do not watch flat panels in completely dark rooms (as we do with front projectors, for example). Most people I have spoken to who are averse to front projection are so precisely because they do not want to watch TV in a completely dark room.

i went with 24ftL i think...bringing down both backlight and contrast brought my gamma up to 2.1...so that helped a lot. my Toshiba sings now...and this was the last thing I needed to address...thanks to Michael, Andrew, and Tom for their insight...I'm a happy TV watcher again

What kind of specific settings are you running, I'd love to know.

thanks.

what do your cuts/gains, backlight, contrast number look like obviously I'm not going to copy exact, but a ballpark so I can get my gamma in the same 2+ as you.

okay so it looks like contrast and cntx are the very same control.

Between those and the drives that will set where you start clipping out your colors on the highend, but more importantly, dropping contrast (via user or service menu) will eventually start getting you more and more into the space where you will have better gamma.

But, it seems you are essentially removing the top 30% of your range though.

hmmmmm trade offs.

the tech from comcast set my cable box to 720p . i have 52xbr4 tv . my tv is 1080p.is that ok? the picture on sd is not clear..hd is just ok.. help! thanks

You really should've started a new thread instead of tacking onto this one, but try setting the cable box to 1080i or p, whichever it'll do, and see what happens. At 720p from the box, the set has to scale and maybe deinterlace the picture, plus any native 1080 content is downrezzed by the box before it's sent to the set. At 1080, any native 1080 content is passed straight through, and the set just has to deinterlace if 1080i is the best your box can output.
