Yesterday evening I had the pleasure of having Michael Chen perform an ISF calibration to my System which consist of, among other things, an InFocus 7210 front projector with an ND2 filter and a Lumagen Vision HDP video projector.

Although Michael did an excellent job – the image is much improved – the following LUMAGEN SPECIFIC issues remain for which I would appreciate the input (no pun intended) from Ofer, Gordon and others more knowledgeable that I:

1. What is the command sequence to save/store the settings as the ISF DEFAULT settings? Also, in this regard, does the command sequence have to be issued once (i.e. is it global and applies to all INPUT/OUTPUT combinations) or does it have to be issued for each INPUT/OUTPUT combination?

2. What parameters/settings in, for example, IN1A change (i.e. are variable / are not global) in the INPUT-RESOLUTION-BASED sub-memories?

3. As part of the calibration process I noticed that OUTPUT MODE, per page 18 of the manual, was changed from SAME to INDEPENDENT noting that the setting for the two inputs that I use (IN1A for my cable box that outputs 480i, 720p and 10870i, IN2A for my DVD player which outputs 480p) is 0/0/0/0. As it relates to the foregoing:

-- Why would the OUTPUT MODE be changed from SAME to INDEPENDENT given (i) DVD resolution is always 480p and (ii) cable box differences for BLCK, CONT and COLR should, based on my understanding be handled via the INPUT-RESOLUTION-BASED sub-memories (i.e. what, if anything, is gained in going from SAME to INDEPENDENT)?

-- What is the intent/purpose of setting the OUTPUT MODE to INDEPENDENT (i.e. what parameters/settings in for example, IN1A OUTSEL 0 versus IN1A OUTSEL 1, change [i.e. are variable / are not global] in the INDEPENDENT MODE? Please also provide an example as my understanding here is less than clear.

-- Should I change the OUTPUT MODE from INDEPENDENT to SAME? If not then why not?

Much thanks in advance.

1: You need to first have service menu of scaler enabled, MENU 0 9 1 0
Then you save the entire config to non volatile memory by pressing MENU 0 9 9 7

It will say something like ISF settings saved on screen. That is every single parameter you have on the scaler saved. You should now turn off the service menu, MENU 0 9 1 0

Now you cna muck around and if you make a mess just press MENU.SAVE>RESTORE and it'll reload the ISF stuff. Of course, you can always muck around anyway and as long as you never save anything then when you power down the product then power it back up it will go to the last saved state anyway.

2: All the stuff to the right of IN on the menu tree are per res based from memory, (480/576, 1080i, 720p, other) but I would want to check that to be sure.

3: Output mode is generally set to independant when you want to use different OUTPUT resolutions on different memories on the same input. ie, In1A may use 720P@59.94 output while In1B may use 720p@47.95Hz output. If you always use the same output res and refresh to your display then it's not going to make any difference.

Hope this makes things a little clearer. The logic behind the input and output configuration and memories is explained in the Basic Setup Guide you can doownload from the Lumagen website

Gordon:

1. Appreciate the reference to the basic setup guide. As a long time user I have read this guide many times but wanted to confirm that I had not missed something in my interpretation of same as it was indicated to me that the purpose of the INDEPENDENT output mode was to control screen positioning (i.e. 480i output vs 720p output vs 1080i output could require different manipulation to ensure all were properly centered on the screen).


2. As it further relales to item OUTPUT MODE:

a) If I understand you correctly that the SAME/INDEPENDENT OUTPUT mode is used when one/multiple resolutions or refresh rates are being out for a given input THEN it follows that:

i) MENU-->OUT-->RES-->VRES and MENU-->OUT-->RES-->TIMING are global for a given input while in SAME OUTPUT mode.

ii) As is the case with the RESOLUTION-BASED sub-memories it would be WONDERFUL/HELPFUL for Lumagen to publish a list of global/non-global variables to assist.

b) As I am feeding my projector a singular diet of 720p@60Hz then there would be no harm in changing MENU-->OUT-->MODE back to SAME


As always, much thanks.

Joel: You appear to understand precisely. Adjustments to MENU.OUT- everything relate solely to the OUTSEL number you are using. So every INPUT memory that is tied to that OUTSEL number will be affected by changes to it. You have 8 OUTSEL numbers to play with. In your system you use just one. So changing to SAME mode should not be a problem

Gordon:

One quick point of clarification -- are you saying that the parameters for a given OUTSEL apply GLOBALLY to ALL INPUTS or LOCALLY to A GIVEN INPUT. Before responding, consider the following:

-- OUTSEL 1 set for 720p @ 60Hz and OUTSEL 2 set for 720@24Hz

-- IN1A set to OUTSEL 1 and IN1B set to OUTSEL 1 where IN1A is used for nightime viewing while IN1B is used for daytime viewing.

-- Is it not the case that DESPITE setting both IN1A and IN1B to OUTSEL 1 that the "other MENU-->OUTPUT parameters" can be customized for each of IN1A and IN1B...in other words, the OUTSEL X (where X = [0,8]) only controls/sets the output resolution and timing?

A final questions -- in calibrating my system the calibrator used the MENU-->IN-->COPY-->COLOR-->ALL command to copy the "color settings" from IN2A to all other inputs while viewing a 480p source. The question here is simple...were the grayscale parameters copied to the 480i, 720p and 1080i sub-memories of the other inputs noting the following:

-- I am not concerned about the BLACK, CONTRAST, COLOR, HUE, COLOR OFFSETS OR HUE OFFSETS as these were individually set for each of 480i, 720p and 1080i; and

-- I believe that the answer to be NO based on my reading of page 24 of the manual which I downloaded today.

-- If I am correct that the answer is no, is there an easy way to copy just the grayscale as everything else has -- per the above -- been tweaked or must I manually enter the grayscale settings through the 11 point convergence available in the service menu?

[EDIT: FWIW, I did check this when I got home and found the following -- the grayscale settings WERE copied to all resolution sub-menus while the black, contrast, color and hue settings WERE NOT...this is exactly what I wanted to happen despite it being different than the manual suggests. Perhaps someone more knowledgeable than me can explain this.]

As always, thanks in advance.

Gordon:

Can you please double check the MENU 0997 command as it did NOT work...that is, no message appeared advised me that any setting were stored as the ISF DEFAULTS...and yes, I was in SERVICE MODE....

Much thanks.

Much thanks.That is the correct command for my HDQ. I just tried it and it worked as described.

Citation444, appreciate your confirming that the command is correct...that said, did you get a message that the settings were being stored as the ISF DEFAULTS as I got no such message....

[EDIT: Never mind...found the problem...I had miscoded the 7 button on my universal remote control...have now fixed this and all is well...HUGE thanks to everyone.]
