GWarp3 PC Tool Quick User Guide
1. Important concept
1.1. Gwarp3 is a PC tool for convenient operation through USB or Ethernet connection.
1.2. Geometry alignment in Gwarp3 is called [Warp Adjust]. OSD or Remote controller adjustment can
only execute geometry alignment up to 9x5 control points but Gwarp3 can be up to 17x17.
1.3. Under 9x5 control point, the geometry result in Gwarp3 will be executed to the Box in real time. It is
the same result as OSD or remote controller operation. User can switch operation between remote
controller and Gwarp3 at any time.
1.4. 17x17 geometry alignment can’t be executed in the Box in real time. User should execute [Save to
Box] process to save the final data into Box and can find the result under [UserMap] OSD menu.
1.5. The data in [UserMap] is different format and can’t recall for further modification.
1.6. The data saved in Profile Index will save all user settings including UserMap. If the UserMap includes
only up to 9x5 data, user can modify it. If it includes 17x17 data, user can’t modify it and can only
execute 2x2 corner finetune with +_50 pixels position shift in H&V directions.
1.7. The data saved in Gwarp3 through [Save Setting] to PC can be as backup or copied to another unit.
User can execute further modification including 17x17 geometry alignment result.
2. Steps for Edge blending setup through GWarp3 operation
2.1. Set output with the same as projector native resolution.
2.2. Connect GWarp3→Select [Pattern] type→ [Warp Adjust]→ [2x2]→ [3x3]→ [5x3]→ [9x5]→ [17x17].
2.3. After finish one channel geometry alignment, please select # and click [Save to Box] to save the
settings into Box. The data saved in each channel is independent.
2.4. Execute [Video Wall] settings. Can be executed in GWarp3 or OSD.
2.5. Execute Edge [Blend] settings. Can be executed in GWarp3 or OSD.
2.6. After finish all settings, go to [System] → [Profile Save] to save all settings into Box permanently.
2.7. User can save the settings in PC through [Save Setting] as backup. The file name is WBF. User can
load back WBF file from PC for further editing or copy to another unit of the same model GeoBox.
3. Geometry alignment through [Warp Adjust]
3.1. Click keyboard [P] to select grid pattern color. [CTRL + P] can disable the pattern and see
background image for OSD operation.
3.2. Start from [2x2] alignment, then follow [3x3]→ [5x3]→ [9x5]→ [17x17] sequence for geometry
alignment. If go back to lower control point adjustment, it will reset higher control point adjustment.
3.3. [2x2] alignment will not reset curve adjustment result.
3.4. User [M] for adjusting Mode selection (2x2, 3x3…).
3.5. Use [CTRL + Arrow] key to select control point.

3
3.6. Use [Arrow] key to adjust control point position with default step (8 pixels/step)
3.7. Use [Shift + Arrow] key to adjust control point position with 1 pixel/step.
3.8. Click # key under [Save to Box] to save the setting. Each channel shall save separately but can save
to the same # for convenient recall.
3.9. After finishing all channel geometry alignment and [Save to Box], click [System] to save all channel
settings into [Profile Save].
4. Switching between OSD operation and GWarp3 operation
4.1. Up to [9x5] geometry alignment:
✓In most of smooth curved application, 9x5 geometry alignment will be enough. User can
execute [9x5] geometry alignment through Remote controller, WebGui or GWarp3.
✓[9x5] settings from OSD operation switched to Gwarp3:
User can open GWarp3 and directly modify the settings under [9x5] or [17x17]. If switch to [5x3]
to do geometry alignment, only [5x3] settings will be kept.
✓[9x5] settings from GWarp3 operation switched to OSD operation:
After user finished GWarp3 [9x5] settings, user has below method to transfer to OSD operation
by remote controller:
i. Gwarp3 operation up to [9x5] will be executed into Box in real time same as OSD operation
by remote controller.
ii. Use [CTRL + P] to turn off GWarp3 grid pattern so that user can see OSD menu and
operate directly by remote controller. User needs to activate [Menu]→ [Anyplace]→ [9x5]
OSD menu for further editing. Don’t use [Warp] hotkey in remote controller because it may
not locate at [9x5] location. If select [3x3] for operation, then [9x5] data will get lost.
iii. Save GWarp3 result into Profile without executing [Save to Box]: user can LOAD the same
Profile from OSD to do further modifications. This is the safest way because even the
result mixed up by OSD operation, it still can be recovered from Load Profile Index.
iv. Save GWarp3 result into [Save to Box]: user can recall the result from [Profile Index] or
UserMap but can’t do further modifications from UserMap due to data format change. Only
4 corner alignment with +_50 Pixels in H&V is allowed.
4.2. [17x17] geometry alignment from Gwarp3
✓After finishing [17x17] geometry alignment, user needs to execute [Save to Box] to save the
data into Box, then save the settings into Profile Index under [System] menu in Gwarp3. The
setting saved in Profile Index will be kept permanently.
✓User can recall [17x17] result from Profile Index by remote controller and combine with other
functions to finish edge blending setting.
✓If user tries to change geometry settings from OSD, it will only keep the data up to [9x5]
settings. [17x17] settings will get lost.

4
✓User can save [17x17] settings in PC without executing [Save to Box]. The file can be re-loaded
for further editing.
✓Before executing [Save to Box] or [Profile Save], [17x17] setting will not be saved into Box.
When power off the system, 17x17 settings will get lost but 9x5 settings will be still inside box.
PS. 17x17 geometry result will not be saved to Box automatically. The data format saved into Box is
also different from other setting. User can’t do further modification through OSD operation.
4.3. Switching GWarp3 to OSD operation
[CTRL + P] in keyboard will turn OFF pattern in GWarp3 and see OSD menu for further operation.
4.4. Switching OSD operation to GWarp3 operation
GWarp3 will detect OSD adjusting result and user can do further modification directly.
5. How to save [Warp Adjust] geometry alignment result
5.1. [Save to Box]:
✓[Save to Box] is a process to save geometry alignment settings into the Box for permanent
keeping inside the Box. It will save the settings for selected channel only and not save all
channel settings at the same time.
✓Select the # and click [Save to Box] on GWarp3 will execute this function. The location to store
this geometry alignment settings are in [Anyplace]→ [GWarp]→ [UserMap #1-#10].
✓Before Save to Profile, user needs to click [Save to Box]. Otherwise [17x17] settings will get lost
and only the setting below [9x5] will be saved.
✓Each channel will save to different [UserMap] location. It is independent. User can save all
channel settings to the same # for convenient recall.
✓The data from Load Profile can’t be saved into [Save to Box]→ [UserMap].
✓If user wants to save warp settings created from remote controller into UserMap, use needs to
switch to GWarp3 operation, then save it into UserMap through [Save to Box].
5.2. [UserMap] data
✓After [Save to Box], user can recall the settings from [UserMap] OSD and combine with Vide
Wall and other functions to create flexible display system, such as all-in-one edge blending or
discrete content in each projector.
✓Regarding Geometry alignment settings inside [UserMap], user can only execute 4 corner
position alignment through [Finetune] menu under [GWarp] OSD. The adjustment range is +_50
pixels in each corner at H&V directions. This is for image position finetune after change lamp,

5
maintenance or position shift.
✓When execute system reset, UserMap will be kept without erase. User can see the result from
OSD or GWarp3 [User Map] menu.
5.3. Save to Profile [Index] through GWarp3 or remote controller
✓User can save [Warp Adjust] result in Profile under [System] menu or through [Save] hotkey in
remote controller.
✓Before save Profile through remote controller, user needs to execute [Save to Box] to send data
to the Box in advance. If not go through [Save to Box] process, [17x17] data will get lost.
✓[Profile Save] will save the settings from all channels at the same time.
✓User can Load the Profile setting through Gwarp3 or Remote controller and do further
modifications. However, 17x17 warp adjustment result can’t be modified.
5.4. Save in PC
✓PC [Save Setting] process will save all data inside Gwarp3 from all channels at the same time
with WBF file extension name, no matter user executes [Save to Box] process or not. User can
load WBF file for further modifications.
✓While executing [Save Setting], user can select to save all channel or single channel data
through the file type selection. If save all channel data, the file extension name will be WBF and
if for single channel data, the file extension name is SBF.
6. Permanently save the final settings — [Profile Save]
6.1. [Profile Save] is to keep settings into Box permanently.
6.2. During the setup stage, we propose user to execute [Profile Save] at each important stage.
6.3. [Save to Box] process shall be executed before Profile Save.
6.4. [Profile Save] in GWarp3 and WebGui will save all channel settings at the same time. If it is saved
through OSD, it will only save one channel settings at selected channel.
6.5. The data Load from Profile Index can be modified by WebGui & OSD.
6.6. If the data is created from GWarp3 [warp adjust] [17x17] and store into Profile. When user recall this
Profile settings and modify it through remote controller or WebGui, all the [17x17] settings will be
reset and only settings under [9x5] will be kept.
7. PC back up and copy — [Save / Load] Settings
7.1. User can use PC to back up all channel settings through [Save Setting] and [Load Setting].
7.2. The file format is WBF. It will include the data in all Profile Indexes.
7.3. The file saved in PC can be served as backup or copied to another Box.

6
7.4. Before the data is saved into Profile Index, it is only kept in PC but not inside the Box. When user
powers off/on the Box again, the system may not show up all settings.
7.5. User can execute [Load Setting] from PC and do further editing. The final result must be saved into
Profile. Otherwise, some settings will get lost after power off the system.
7.6. GWarp3 will detect the information in the Box when it is connected. Some setting in the OSD may not
be implemented in GWarp3 (such as PIP data) and can’t be saved into PC at the same time.
8. System Reset
