1 Introduction
VWC-44 is a dual channel professional curved screen edge blending processor. I was designed for
sophis ica ed edge blending as well as image warping, s acking, projec ion mapping, irregular video wall and
passive 3D…e c.
5 inpu s and 2x HDMI ou pu s are in egra ed in VWC-44. Inpu por s suppor up o 2560x1600 /
3840x1080 @60Hz and 4k UHD @30Hz resolu ion wi h 4:4:4 full color sampling. I is in egra ed wi h 10-bi
high end processor wi h mo ion adap ive de-in erlace, 3:2/2:2 pull-down and suppor s non-VESA s andard
inpu iming Advanced warp echnology is embedded in VWC-44. User can use fron panel keypads, IR con roller
and PC ool o perform edge blending and sophis ica ed geome ry alignmen up o 17x17 grids. Independen
color (whi e balance) adjus men for each projec or, overlapped area colour correc ion and non-overlapped
area black level uplif are also s andard func ions VWC-44. Users can see real ime geome ry and colour
adjus men and ge op imized resul .
HDMI loop ou suppor s daisy chain connec ion up o 3840x1080 @60Hz or 4k/2k @30Hz and allows
large display wi h mul iple VWC-44 cascaded. Video wall func ion in VWC-44 is o crop and alloca e source
image for each projec or. Comple e curved edge blending can be achieved wi hou PC, video dis ribu or and
spli er.
If PC tool is required for sophisticated geometry alignment, user can save the final result into
VWC-44 and remote PC. During operation, no PC is required. It will provide a flexible and reliable
system. Wi h VWC-44, users can replace high end projec or wi h low cos projec or wi hou lens shif , warp
and edge blending. I provides easy configura ion, lower sys em cos , reliable and flexible solu ion.

4 Help ul Tips or system installation and setup
a. Selec digi al inpu o ge be er image and avoid image posi ion shif .
b. If 4k signal connec ion dis ance is more han 10m, please selec a cer ified HDMI cable o avoid
uns able signal connec ion.
c. The quali y for signal adap er or conver er, such as HDMI o DVI adap er and DisplayPor o HDMI
conver er, may downgrade he signal quali y and cause issue. Please selec qualified ones.
d.
If user can see blue background image wi h [Power Saving Mode] message, i means he signal
connec ion be ween projec or and AV-BOX is OK bu no inpu signal de ec ed by AV-BOX.
Please check signal source or replace a differen inpu source o es .

d. User needs o do geome ry adjus men and warping func ion o align he images on o curved screen
and le he images be ween wo projec ors have he same grid size and wi h necessary overlap pixels.
e.
Af er geome ry and warp adjus men , user can apply Video Wall func ion in VWC-44 o spli he
image, cropping he correc area and assign o each projec or.
f. The las s ep is o do edge blending o combine he images in o one seamless big screen.
g. If he applica ion is in dark environmen , o do [Offse ] compensa ion is required o elimina e black

1. 4 projec or edge blending can be configured as below:
2. 4 projec ors edge blending in o one con en
3. Independen wo discre e con en s (2+2)
4. Two projec ors edge blending and one single projec or display wi h original aspec ra io.

5.2 Case C: High resolution Edge Blending with multi-windows display card
a. Usually, each full HD signal can feed up o 3- 4x projec ors for 10m screen and s ill keep accep able
video quali y (i will also depend on he wa ching dis ance).
b.
Many video cards can easily provide up o 4x 3840x1080 ou pu s for VWC-44
c.
Each PC ou pu is fed in o one VWC-44, hen o wo projec ors. 4 ou pu s will be fed o 8 projec ors.
d. If he overlap pixels is 250, hen i can provide a video wall wi h 13,610x1080 ou pu resolu ions.
e. If he wa ching dis ance is 5m, he video pixel pi ch can be abou 5mm. In his case, he o al screen
size can be up o 13610x5mm=68m and s ill keep accep able video quali y.
f.
The display card should have he func ion o se overlapped pixels be ween wo ou pu por s. In he
case of four ou pu display card, PC should be able o se overlapped pixels be ween ou pu P2/P3,
P4/P5 and P6/P7. The overlapped pixels should be up o abou 20%-25% of he ou pu resolu ion.
The res overlap areas (P1/P2, P3/P4, P5/P6, P7/P8) can be se by AV-BOX.
g. If he display card doesn’ have above men ioned overlap se ing func ion, hen user needs o crea e a
con en wi h some overlapped pixels up o abou 20%-25% be ween ou pu s.
h.
AV-BOX can do geome ry alignmen , spli he image, assign image for each projec or and cap ure
he righ size of he image for edge blending.
i.
If one ou pu can be connec ed o wo VWC-44 hrough daisy chain connec ion, one 3840x1080
ou pu can be connec ed o 4 projec ors and o al projec ors will become 16. If one PC ou pu can
be daisy chain connec ion o 3x VWC-44, hen 4 ou pu will connec up o 24 projec ors and he o al
video wall can be more han 50m and s ill wi h good video quali y.
j. The advan age for his kind of applica ion is high ou pu resolu ion. However, i s ill has some
limi a ions.
The major inpu source shall come from PC bu no from mul iple inpu sources
The PC shall have enough processing power o handle mul iple ou pu windows. More video
ou pu por s from display card will occupy more PC resource.
Differen playing con en s may also require differen CPU resource. User needs o es before

VWC-44
13
implemen his kind of display sys em.
The ou pu aspec ra io will be changed depending on he display sys em. User needs o ake
care of he aspec ra io in he source con en in advance.
k. Edge blending will increase he o al resolu ion. Usually, he video quali y will be good enough for mos
of he applica ions if ou pu resolu ion in each projec or can reach XGA resolu ion.
l.
User can connec wi h o her signal sources like Blue Ray or Media Player o o her inpu por s in VWC-44. By
selec ing differen inpu por s and applying differen AV-BOX se ings, i will provide differen display modes. For
example, for 3 projec or edge blending, user can se all hree edge blending, wo projec or edge blending and one
has discre e display or each projec or has independen con en .
m.
AV-BOX can reduce he CPU loading in PC and reserve more CPU resource o handle in erac ive
or o her opera ion wi hou image lag.
5.3 Case D: “L/M” shape video wall with edge blending
Below is example of he applica ion in res auran wi h “L” shape video wall:
a. 3x WXGA projec ors: wo projec ors edge blending on he fron screen and ano her projec or is loca ed
a side wall.
b. The image is me a he corner. I is no necessary o do edge blending a he corner. User jus needs o
do geome ry alignmen o le he image mee a he corner.

6 Internal Grid Pattern or Geometry Adjustment
To press [PATTERN] key in Remo e Con roller or a fron panel, i will show in ernal grid pa ern. By

or other signal sources or see OSD menu instead of internal grid pattern, user can continuously click
pattern key to show it. A flashing indica or a he adjus ing poin will appear. User can see real ime grid
pa ern change during he adjus men . I is recommended o connec hrough digi al in erface (HDMI or DVI)
o he projec or o avoid any posi ion shif af er ins alla ion.
If user wan s o show he adjus men value (pixel #) while doing geome ry alignmen , user can
con inuously press [Pa ern] key o show he adjus ing value.
Note: he grid size of VWC-44 is 32x23 pixels and other model is 50x50 pixels. If user wants to do edge
blending with VWC-44 and other model, user needs to apply external grid pattern so that all AV-BOX will
show the same grid pattern. Please download [Edge Blending grid pattern] from AV-BOX website.
Continuously press [Pattern] hotkey, user will show the same external pattern in all projectors for easy
geometry alignment. If user uses Gwarp PC tool, user can set grid size to 50x50 to get the same grid
size in all projectors.
