Greetings Colleagues,


Herein are the hdmi settings for the Sharp Aquos LC 26SB28UT, using DVE and AVS Forum 709 disks. The brightness technique used was the 21 bar blinking on the AVS Forum brightness pattern. Color temperature warm was used because standard and cool settings washed out color tone too much. Color and Tint settings used blue filter with AVS Forum color pattern.


Colorimeter was not used for greyscale calibration, due to suggestions in this forum that the service menu for this model is too complicated. Besides, this is my wife's tv that I rarely watch and I was not going to put that much effort into greyscale calibration. The picture quality looks pretty good.


If using a cable box, make sure the box's internal settings are set for 16:9 picture type with output set to native.


Picture Settings:


DBC: Off

Film Mode: Off

DNR: Off


Brightness: 25

Contrast: 50

Sharpness: 14

Color: 17

Tint: -2

Color Temperature: Warm

Blacklight 10

New Settings Based on AVS Forum 709 Disk APL Clipping Pattern.


Greetings Colleagues:


Here are the revamped settings for Warm and Standard modes, using AVS Forum HD 709 Disk, APL Clipping Pattern, which is the 2nd pattern that comes after the Black Clipping Pattern, and is described as an APL for use in a "typical viewing environment." This pattern was used to adjust brightness level because the previous setting was too dark. As recommended, the brightness was adjusted where bar 19 was barely visible. Calibration patterns used were full field patterns from the Gamut Calibration Disk from this forum.


For you calibrators, this television has some pretty even red, blue, and green gains and cuts. Warm setting was measured at temperature of 7000K, and standard setting measure at D93 (9300K). Gamma graphs were pretty much level without any significant adjustments. These graphs are attached for your convenience. I did not go into the service menu.

Picture Settings:

Color Temperature Warm - Preferred Mode


DBC: Off

Film Mode: Off

DNR: Off


Brightness: 27

Contrast: 50

Sharpness: 14 (20 using maximum sharpness technique)

Color: 18

Tint: -1

Color Temperature: Warm

Blacklight 10


For movie mode: contrast setting of 50 produces light output of 59 ftL @ 100% ire - good for a very bright room - recommended. To reduce light output to 50 ftL for average room lighting, change contrast to 38 and brightness to 28. For darkly lit rooms for a light output of 40ftL, change contrast to 34 and brightness to 29.

Color Temperature Standard


DBC: Off

Film Mode: Off

DNR: Off


Brightness: 27

Contrast: 50

Sharpness: 14 (20 using maximum sharpness technique)

Color: 18

Tint: -1

Color Temperature: Standard

Blacklight 10


For standard mode: contrast setting of 50 produces light output of 60.9 ftL @ 100% ire - good for a very bright room - recommended. To reduce light output to 50 ftL for average room lighting, change contrast to 38 and brightness to 27. For darkly lit rooms for a light output of 40ftL, change contrast to 33 and brightness to 27.

The Calibrated Settings (Service Menu Tweaked)

Greetings Colleagues,

[Updated tweaked settings in bold]

It has been some time since this television was tweaked due to my inability to access the service menu. Then Eureka! I discovered that this Sharp LCD was manufactured by Orion, according to another forum member. Service menu access was easy, using a different code.

The calibration process is easy for this television and the rgb levels track perfectly without the need for any CMS. Changes in the service menu will affect each individual temperature setting (standard - listed as "N" in the service menu, warm - listed as W, and cool - listed as C) but the user menu settings will be okay for all temperature settings without the need to adjust them for the individual temperature settings.

The gamma curve, after calibration, is just about flat as can be (see graph below) and adjusted for 2.1 @ 0% ire field window. Contrast setting was reduced to eliminate tinting in grey scale pattern and backlight setting adjusted to have 50ftL @ 100% ire field window. Pre calibration service menu settings for warm temperature showed that the red color was too low and blue color to high (BDrive (W) reduced from -24 to -27 and RDrive (W) increased from -4 to 1). Standard temperature showed that blue color was way too high (9100 color temperature) and BDrive (N) was decreased from -8 to -14 and RDrive (N) was increased from -8 to - 3 to achieve a 8000K color temperature for the standard temperature setting.
Picture Settings:

Color Temperatures Warm (6500K) and Standard (8000K)

DBC: Off
Film Mode: Off
DNR: Off

Brightness: 29
Contrast: 38
Sharpness: 09
Color: 18
Tint: -1
Color Temperature: Warm and Standard
Blacklight 10
