Question concerning tv screen size compared to seating arrangement in movie theatres.
Many questions have been asked as to distance of seating arrangement compared to screen size when buying large screen tv's.
I sit 15' from my 60" tv and knowing that the theatre picture contrast doesn't compare to my tv display I have never heard anyone complain about the theatre movie experience picture being to large because of the seating arrangement. Let me explain...
In a movie theatre the screen looks huge compared to the seating arrangement but no one complains about screen size.
Is there a standard the industry uses comparing the seating distance as to the screen size?
What is the screen size and seating distance? tough question..I know
Seems that most people sit in the front 1/2 of the theatre making the movie experience at least twice as large as their home theatre experience. But most of us,myself included,was concerned about screen size being to large for home viewing. After the initial eye adjustment period we wish the screen was larger.
Just thinking out loud

Also, bear in mind that the THX recomendation doesn't take in account differences in resolution between HD and SD. Although HD may look great on a 60" SXRD at 7 or 8 feet, SD is another story.

There are guidelines and suggestions regarding viewing distance, but no hard and fast rules. It comes down to your personal preferences and what distance your most comfortable.

I sit about 9' from my 60" and this is by no means too close especially when viewing DVDs or HD material.

When you first get a large screen it will look huge, but believe me, it will start looking smaller and smaller and soon you'll want something bigger. When I got my last set, I went for a 50" because I thought the 57" of the same model was too big, and kicked myself for six years for not getting the bigger set.

I am really questioning the guidelines because as I mentioned above the movie theatre experience (screen size) is really large but nobody complains and really gets enveloped to the movie experience. Over a year ago when I was looking at which tv and screen size to get I was lookng at the 42" displays. My bride and I went to the theatre and as we were watching the infomercials b/4 the movie I thought the 42" display would be a little larger than my existing 36"crt. Here I am paying money to see a movie on the biggest screen in the area and loving it so why not get the biggest display, for the best buck, for everyday entertainment at home.
For those in the market for a new display for home viewing...GO LARGER SCREEN!

I read that review the other day.Does it seem right to anyone else thinks you should put the Iris on "min" and advanced iris on "high" to get the best contrast ratio cause im in a room with no lighting.

Thanks everybody for thier input!

I'm doing the upgrade to the 60". I am going to call HiFi Buys today(Tweeter) and see if they will do an exhange since it has only been three weeks since the purchase. Has anyone heard of anybody doing this before. Do I just say that I am unsatisfied w/ my purchase and "need" the 60". Do they charge extra fees (restocking fees etc..) for something like this? I hope this does not turn into a headache!

This briefly describes using the Sony SXRD internal service menu white balance adjustments in the neon green menu PANEL NVM OK menu section. I'm not an expert and this is not definitive, so use at your own risk and write down any values before making changes.

For getting in and out of the service menu, refer to this post.

If you follow that post to check lamp hours, you are in the correct service menu when you see PANEL NVM OK at the top left.

Using the remote, simply press the [2] or [5] key to navigate until you see 2 WB category menu top left. From that point, you'll use the [1] and [3] keys to navigate to items within that category menu. Then use [3] and [6] to make changes to the items shown below.

The white balance values correspond to the color temp mode in effect when you enter the PANEL NVM OK menu. If you change values, you'll need to save them before choosing a new color temp mode or the settings will be lost. The following documents the gain and bias white balance adjustments within the WB menu along with my (Feb build) original factory values:

2 WB category menu:

---------- Cool, Neutral, Warm

3 R_GAIN 130, 128, 128
4 G_GAIN 136, 124, 112
5 B_GAIN 128, 105, 67

6 R_BIAS 128, 128, 128
7 G_BIAS 128, 129, 129
8 B_BIAS 128, 130, 131
To save changes, press [MUTE] [ENTER].

The menu button on the remote does not seem to work in the PANEL NVM OK menu, so I press [JUMP] (pause 2 seconds) [JUMP] to get to the QM INFO SERVICE DTV menu first. The menu and navigation buttons on the remote work in this QM INFO menu. To return to the PANEL NVM OK menu, simply press [JUMP] 2 times. You need that pause for the first set of 2 JUMP presses because of a delay in getting to the first screen.

These changes appear to affect the baseline white balance for all inputs for the 3 color temperature settings; cool, neutral and warm. I was able to make cool look like neutral for example. There may be a way to adjust specific inputs individually, but I've not explored beyond the WB menu too much.

The smaller step values in this WB menu appear to provide a finer level of adjustment compared to using the PRO mode user white balance section. You may want to feed a grayscale ramp from your DVD or PC during adjustments or use the built in test patterns described from this post. If you use the built in test patterns, the jump button works, but you'll be driving in the dark since the test patterns are on top making ALL other menus invisible.

Caution: On my screen, increasing the B_GAIN (blue) created temporary color uniformity issues on the right side of the screen with my grayscale ramp fed from the HTPC. In fact, cool B-GAIN at 128 is just over the edge of creating an issue on the right side of the screen that I don't see with the lower value neutral and warm settings. Extrapolating this, for those with uniformity issues, you might be able to reduce uniformity issues by reducing the GAIN on all 3 colors?

While this post documents the ability to make these changes, mine are at factory values because I found that the PRO white balance adjustments (in the user menu) are currently meeting my needs. I'll update this post periodically as more information becomes available from feedback.

Great post. Has anyone found the overscan offsets? I need to reduce overscan. Thanks.

Can changing these settings help reduce the "green blob"?
Has anyone had any experience with that?

I recently ran Avia on the Sony, and on the Overscan and Pixel cropping screens, it appears that the screen is decentered vertically. Ie; it shows an overscan % of 2% at the bottom and 4% at the top. Side to side is perfect.

How do you correct for this?

There was a big upsurge of troll activity from akastp et all. So I guess the moderators had to remove the threads to sanitize them, then put them back.

Actually akastp is being trolled upon by somebody that keeps creating numerous accounts which the mods end up deleting. Maybe the mods had to clean house.

It wasn't AkaStp, it was a troll, one of his names was "Aka5tp" with a 5. He's been rather pesty, and the mods cut out couple hundred posts.

I just read the "Test Bench" article on the SXRD from Sound and Vision Mag and they mention that the default Pro/Warm grayscale is very close to D6500. This is in line with the review over at CNET. Should I just leave it at that setting and just adjust color, contrast, brightness, etc? It seems that all the white balance settings posted here are just drifting further from a very good default color temperature.

Since I won't have an ISF calibration for at least six months when I move, is it best to just leave it at the default Pro/Warm? Or are some of these user posted white balance settings more accurate? I'm currently using rlb's, which he stated were very close to correct except for the blues. I've adjusted the blues and my settings are:

RGain: -9
GGain: -15
BGain: -3
RBias: 3
GBias: -3
BBias: -4

Please help! I'm a stickler for an accurate picture and since I can't get a good ISF calibration here in Boise I'm stuck with user modified settings. Thanks!

Well that name isnt registered anymore, so whichever name variation, they all got booted for some violation.

AkaStp didn't get booted. He had enough of the conflict, and took an AVS vacation.

As part of that vacation he ask to have his messages purged since so many of them were involved in "contesting" with the troll.

I'm having a lip sync issue on some material that I'm hoping someone can give me some insight on how to correct it. DVD's look wonderful and no problem at all with lipsync. But occasionally on some OTA HD recordings (Fox a few times) and also with the HD channels on DTV (especially HDNet) I'm getting some annoying lipsync problems. Thanks for any help you can provide!

What more can we do to help you with this? I gave you my white balance settings a couple of weeks ago, and you weren't satisfied with them. Rlb has given you his, and you don't seem to be satisfied with them either. Lots of other settings have been listed on this thread. None of them satisfactory either?

It seems like you want some sort of reassurance that you've got the best white balance settings for your set. Short of an ISF calibration, or buying one of those Spyder TV gizmos, there's no way you're going to get perfect white balance. For now, at least, you're stuck with your eyes. The best you can do is try some of the settings others are using, and adjust from there to find settings that look good to you.

Sounds like you like the defaults better than the settings others are using. Great. If the defaults look best to you of everything you've tried, leave it there until you get your ISF calibration.

Phenwick,

So I took your advice and bought a DVI-HDMI cable to hook up my PC to the Sony. The picture looks a lot crisper but I am still having issues with resolutions. When the PC is booted up and loaded, it displays a 1280x720 resolution and everything that is not true 780p, 1080i, etc. resolution does not show. If I choose a different resolution, the screen flashes and shows nothing but black. Then the sceen pops back up with the old 1280x720 resolution setting. I am assuming that this black screen is where the popup window is asking me to confirm my settings. If nothing is inputted, it defaults to the original resolution. The problem with the 12980x720 resolution is that the desktop is now off the monitor viewing area and there is no option to scroll the mouse to move the desktop. That is okay since I would rather have it all on screen.

Now that you guys mention the overscan issue, I am correct to assume that the resolution is properly set on the PC but the monitor needs to be adjusted to compensate for the overscan? If I enter the service menu and change the overscan numbers, will this affect my other inputs as well?

I must say that this is frustrating. I also recently purchased a Sony HDMI DVD player (DVPNS70) and its showing most newly released DVDs with the black bars still. I have tweaked with the settings a bit but I believe the DVD is the culprit. I really love this TV and if I can just get these issues resolved, I think I will be okay.

Anything with an aspect ratio greater than your TV's 16:9 (1.8:1) will give you black bars on the top and bottom. Anything with an aspect ratio less than that will give you pillars on the sides. Simple geometry. The aspect ratio of a particular dvd is usually listed on the box.

What bhollis wrote is correct. Check the link at the bottom of my message for more aspect ratio information than you will ever need.

htwait,

Thanks for the link. I guess I was naive when it came to the presence of black bars on DVDs. On my old 47inch Panny, I guess my settings were established in a way that I did not realize the black bars. Maybe I was in Zoom or something. Thanks for educating a newbie.

I am have the same problem, A 60" SXRD and a DTV HR10. I made it alittle better by removeing the optical audio line feeding the av receiver, and feeding the av receiver direct from the SXRD. The SXRD is feed by a HDMI cable. I do not know if this is good or bad.
