0.1 Recommendation of PC and Graphic Card

• PC : Tower PC with extra slot.– CPU:Core i7 or more. Memory:4GB or more

• OS : Windows 7– Win7 only support overlapping multi display function

• Graphic Card– Matrox M9120 PCIe x16 (Blending 2 projectors only)– Matrox M9148 LP PCIe x16 (Blending 4 projectors)

0.2 Setting of PC Software (Matrox_M81203 ）

Install “Matrox PowerDesk”

 

1. Open “Matrox PowerDesk”

 

2. Select 1: Multi-Display Setup

　　 2-1) Resolution of "Display1&2" ->1920x1200.

　　 2-2) "Basic Configurations" ->"Use stretched mode“.Confirm and return to Home. 

 

3. Select 3: Edge Overlap and Bezel Management

　　 3-1) Select "Edge Overlap" and click "Modify“.

　　 3-2) "Hidden pixels" ->"Horizontal" Set “480 pixel(s)”*

Now PC can output multi-display for edge blending.

* Around 20~25% overlapped image seems to be natural in general.

1. Adjusting flow outline

Calculate the position of projectors

Set edge blending width in PC software attached in the graphic board

Set a different ID number for each projector (ID:1~3)

Set “Picture Menu” of each projector as same setting.Picture Mode : Standard/Color Temp/Gamma Mode : Graphics2 is better

Adjust color and brightness of each projector by using “Color Matching.”

Set the positioning of Edge Blending in order that the green line of one projector overlap with the red line of the other projector.

Adjust the black level of no blending zone using “Zone Black Level Adj.”

Set “Blend Gamma” of blending zone.

2. Position of projectors

• What is your screen size ?– Recommended screen aspect w 3,360 : h 1,200

i.e) Screen size of demo roomW 4,100mm x H 1,610mm

Overlap area 480 dot

Image size : 4,100mm x 1,464mm

• Throw distance ?– You can get the distance using “Projection Simulator”

– FHZ55/FH36/31 with standard lens case,the distance is almost same as the screen width !

2. Position of projectors

• Positioning is most difficult in edge blending process– Ceiling mount is better than desktop setting. If someone touch them, the position of

projector would change on the desktop.– Vertical and horizontal lens shift : “0” is ideal. If you use shift function widely, we can’t

project correct rectangle especially horizontal lens shift. It would be a little distorted. So we can’t lap over the red and green line.

• Screen– Don’t use silver screen because we can realize the difference of brightness depend on

the standing point.– Check the screen before you adjusting.

• Set the same dot numbers of overlap zone (edge blending width) as PC software and projector.– PC software may be able to display the adjusting test pattern. So please check it.

3. Adjust “Color Matching”

• What is “Color Matching”– For correcting the brightness and color of the whole projected image

manually from the signal level in six steps, Lv1(black) ～ Lv6(white).• Brightness

• Color (“G” is fixed, adjust “R” and “B”)

• How to adjust– We can only decrease the brightness and color in Lv6(Highest

level). So adjust higher brightness and color projector to lower one.• It is easy to adjust it by using “Incident Color Meter” or such devices.

• Once you set “Picture Menu” of each projector as same setting, it’s easy to adjust them.

– Adjust from Lv6 to Lv2. Don’t need to adjust Lv1.

– Had better to adjust color matching before adjusting edge blending.

• When you adjust color matching, you should set each projector not to overlap. (zooming out is useful)

3. Adjust “Color Matching”• How to adjust using “Incident

Color Meter”

Lv6

1. Adjust brighter brightness to darker one

2. Adjust lower “y” value to higher one decreasing “B”

3. Adjust higher “x” value to lower one decreasing “R”

4. Fine adjust to repeat 1-3 if necessary

5. The result of “x,y” value is goal for lv5 to 2

Lv5 to 2

6. Adjust brightness

7. Adjust “y” value to the goal controlling “B”

8. Adjust “x” value to the goal controlling “R”

3. Adjust “Color Matching”

Incident Color Meter

BrightnessAdjust to 10ths digitIn this case, you can read approx. 310

“x, y” valueAdjust to 3 places of decimalsIn this case, you can read approx. (0.375, 0.394)

4. Edge Blending

• Adjust black level of “A” and “B” to “C”(Zone Black Level Adj.)• Adjust gamma of “C”(Blend Gamma)

Set the same dot numbers of overlap zone as PC software

and projector.

Brightness decrease linearly in this blending zone.

5. Adjust “Zone Black Level Adj.”

• Black level of Zone “C” is brighter than zone “A” and “B” because 2 projectors project this zone at the same time. Adjust black level of zone “A” and “B” brighter to zone “C”.

• Basically don’t change the black level of zone “C” (Zone 6 of PJ-No.1 and Zone 4 of PJ-No.2).

• Don’t need to adjust “Color Matching Lv1” because we must adjust black level here.

• Had better to adjust black level using “Incident Color Meter” when it is difficult to adjust it only seeing– Measure in the dark place.– Had better to measure around the boundary line of blending

(When adjusting using xy value)Adjusting (x,y) value of zone ”A” and “B” to zone ”C” .• Adjust “x”

• Increasing ： Increase “R”.• Decreasing ： Decrease “B”.

• Adjust “y”• Increase or Decrease “G”.• Increase or Decrease “B”.

5. Adjust “Zone Black Level Adj.”

6. Blend Gamma

• What is “Blend Gamma”– Adjusting “blend Gamma” of overlapped zone because the

line of the edge of blending zone become inconspicuous.• Adjusting Range

– 2.3 power （ Mode5 ）～ 1.9 power （ Mode1 ）– Default ： 2.2 power （ Mode4 ）

• Know how– First set “Gamma mode”=Graphics 2 initially and adjust it.– Adjust it projecting all black or all white color– Basically select same gamma of each projector.– Bigger number （ 2.2 power ～ 2.3 power/Mode 4/5) is better

from our own experience.
