• IR receiver is on Front Panel. One 3.5ø mm audio connector for IR extender is located at Back Panel of M811L. 1.8m IR extension cable is equipped in the packing. User can add audio cable to extend the distance up to more than 20 meters.
• IR remote control system is possible to be interfered and cause abnormal or discontinuous operation. Under this condition, PC Tool via USB or Ethernet operation may be the best choice.
  
  

Individual OSD control in multi-unit application

If multiple units of GeoBox is installed together or the IR receiver is put together, in order to avoid interference among multiple GeoBox during the installation, user can set different ID number for each GeoBox under [Options] Setting] Box ID] Menu. Press number keys in Remote Controller to determine which GeoBox can be controlled.

• 851: control GeoBox ID No. 1
• 853: control GeoBox ID No. 3
• 850: to unlock all units and user can control all GeoBox.
• If user presses 851, only ID #1 GeoBox can be controller through OSD. The rest units of GeoBox will be locked. The channel key LED will show blinking light with 1 second interval.

OSD menu Lock and Unlock

When continuously press [Menu] key in IR Remote Controller or front panel for 5 seconds, the OSD function will be locked and channel key LED will light up with 0.5 second interval. To press [MENU] key for 5 seconds will unlock OSD Lock.

System information and in/out LED indicators

• Once input signal and output ports are properly connected, LED indicator on the front panel will show up. If any of the LED in each channel is not lighted up, please check the in/out connection and cable.
• User can check detailed system information by pressing [INFO] key on remote controller: Select press [INFO] show system information on OSD.
  
  

Geometry Alignment

Geometry alignment is to align the image position to let the projection image match the screen and also let image grids between two adjacent projectors be stacked together

Geometry alignment via IR controller & OSD

IR receiver is on the center of front panel. Please be familiar with OSD operation from remote controller, including activating grid pattern, channel switching and hot keys for [Input selection], [Output resolution selection], [4 Corner], [Warp], [Video Wall], [Edge Blend], [Pattern] and [INFO].

• User can install IR extender receiver near screen for easy GeoBox operation (Please add audio extending cable to extend the distance up to 20 meters). If multiple units of GeoBox are used and IR receivers are put together, please set [Box ID] for each GeoBox so that user can control each GeoBox separately through [85x] command. (Please see Section 2)
• Each channel should execute geometry, video wall setting and edge blending setting separately.

Select appropriate Grid pattern color

• The default grid size is 32*32 pixels. User can select different grid size under [Anyplace] Blend] Grid].
• Use channel selection keys and [Pattern] hotkey to show grid patterns in all projectors. Press [Pattern] key again will change grid color.
• To set two different pattern colors in adjacent projectors will be more convenient during geometry alignment.
• User can select the last pattern mode [OSD Value + background] and apply external test pattern for geometry alignment.

[2×2] 4 corner geometry alignment

• In most of applications, no need to do keystone correction in the projector before geometry alignment.
• If using short throw ratio projector in curved screen display, the image will have big distortion. Please use projector to do geometry alignment first before GeoBox.
• [2×2] alignment will adjust whole image with the same scaling factor. [Warp] alignment will adjust only some portions of the image.
• Please follow the sequence [2×2] 3×3 [5×3] 9×5 [17×9] to do geometry alignment to ensure entire image will have uniform scaling factor.
• If the screen is curved, it is possible to have some image inside or outside the screen after 2×2 adjustment. However, it doesn’t matter once the image covers entire screen before 4 corner adjustment. [Warp] alignment can adjust the image position back to required position.
  

[3×3], [5×3], [9×5], [17×9] Warp alignment

• After finish [2×2] corner alignment, apply [3×3 Curved] geometry alignment to let 9 adjusting points be located at the required position including 4 corners, edge center points and center line position.
• Please use [5X3], [9×5] & [17×9] for further geometry alignment.
• For curved screen, the image side edge and center position will have difference grid size. The adjacent projector grid size will also change gradually, user can use Linearity Grid Line adjustment (in next section) to adjust the grid size and correct the image position within shorter time.
• After finish Warp alignment, user can use [2×2] for complete image position fine tune without changing the Warp result. If user executes [3×3] alignment again after [17×9] alignment, [17×9] grid position will be reset and only keep [3×3] grid point information.
• Geometry alignment range from remote controller can be up to 600 pixels in [2×2] + 600 pixels more in [3×3] for one corner/edge.
• If over GeoBox geometry adjustment range, the image will be broken. Please adjust projector installation position or use projector geometry alignment function to cover some adjustment.
• Ultra-short throw ratio projector is not suitable for curved screen display due to big image distortion. Once user can execute geometry alignment to required position, the image quality will be reduced, especially in the Text mode.
  

Linearity Grid Line adjustment

This function can quickly shift complete pattern grid line in both H&V directions.

• Linearity grid line adjustment is under [3×3], [5×3], [9×5] & [17×9] warp alignment menu. User can select the control point, then press ENTER to do grid line position adjustment. Each control point can shift the grid lines in both horizontal and vertical directions.
• When user projects the image to curved screen, the image grid size will continuously change— the grid size at the center will be bigger than both sides. Ultra-short throw projector will be more serious. Linearity grid line adjustment is designed to correct this kind of grid line gap difference.
• This function can co-work with Warp function.
  

Corner Wall geometry alignment

“W” shape Corner Wall geometry adjustment

Important note : When apply Corner Wall function, all the other geomtry alignment function will be disabled. User can only execute geometry alignment through 10 points of Corner Wall adjustment. 4 corner control points can execute 4 corner alignment same as [2×2] geometry alingment function. Edge Blend function will be still available.

Corner Wall alignment allows user to adjust the image at 90 degree corner wall or images at two sides of the pillar at wall corner through 10 control points across the edge of the image. It can execute horizontal and vertical corner wall alignment. User can only select either horizontal or vertical alignment at one time. This function can’t co-exist with warp function. The image position can be adjusted as below:

• 4 corner positions of the image. The whole image position will be shifted the with same scaling factor. The adjustment range is 1200 pixels in both H&V directions.
• The rest 6 control points can correct the image position at wall corner or the images at two sides of the pillar at corner wall. It can shift the image positions in horizontal and vertical direction with the control range up to +_1200 pixels.
• User can’t use ultra-short throw ratio projector for corner wall application. Otherwise, the image distortion will be too big to be adjusted and may also create focus issue. The ideal projector throw ratio should be larger than 0.8:1.
  
  
  

Corner wall application on curved screen

If user wants to implement Corner Wall function on curved screen, user can connect the signal to another G116 or G110 to do warp alignment, then connect the output to another unit for further Corner Wall alignment. Then user can execute curve alignment and Corner Wall adjustment at the same time.

Important notice on curved screen application

The image quality in Corner wall adjustment will be degraded due to big geometry alignment. It is recommended to apply only multimedia content in this kind of applications. User can display the images at different side walls with different projectors to get the best video quality. GeoBox can crop correct image to get the right scaling factor based on the wall dimensions.

Edge mask

There is one edge mask functions in M811L.

• [Edge Mask]: There are 8 control points for edge mask. When user moves the position for each control point, it will result various edge mask effect. The maximum position adjustment for each control point is +_ 900 pixels in H&V directions.
• The starting point for [Mask] is calculated from the original edge position before geometry alignment.
• When implement edge mask, OSD menu will be also masked. User can change OSD location to avoid this issue or to implement through GCT will be more convenient without OSD masked issue.
• Please access [Edge Mask] through [Anyplace] Edge Blend] Mask]
  
  

Video Wall Settings

• The purpose for Video Wall Setting is to split the image and assign specific image to each projector.
  • Zoom: split the image for each projector
  • Pan: assign image location. The location is counted from Left to Right and Top to Bottom.
  • Overlap: set cropping pixels in overlap region.
• Each channel shall execute [Video Wall] settings separately.
  

Zoom—split the image

• Based on the required image cropping size to set the Zoom value. If set horizontal ZOOM=2, the image will be stretched to double size in horizontal and half of the image can’t be seen. User can use PAN to select visual image in LH half or RH half.
• Vertical ZOOM is to stretched the image in vertical direction similar to horizontal ZOOM. If user sets ZOOM H=2, V=2, user will see only 1/4 of the image. User can use PAN to select the visual section.
  
  For 3 displays at horizontal position, Horizontal Zoom=3,
  Vertical zoom=1
  For 3×3 displays (9 projectors), Horizontal Zoom=3, Vertical
  Zoom=3

[Pan]: assign image location

Use [Pan] to determine the location of
each split image in both horizontal and
vertical directions.
– Default setting:
Horizontal Pan=1
Vertical Pan=1

For No. w display: For No. z display:
Horizontal Pan = 3 Horizontal Pan = 3
Vertical Pan = 1 Vertical Pan = 2

Overlap

• Image pixel cropping range is up to +_1800 pixels for image position shift, aspect ratio adjustment, bezel compensation and creating overlap region for edge blending.
• User can crop any location of the image with variable size and shape through video wall function. User can use Zoom and PAN to crop the rough cropping area, then use OVERLAP function to do detailed pixel by pixel adjustment to get the exact required region.

[Position]: shift image position without changing image size

After cropping, user can shift image position at H&V directions without changing image size. Usually, it is for video wall application to fine tune image position. In projector edge blending application, user only changes Overlap value in one edge but not execute image shift.

Miscellaneous Settings

HDMI vs. DVI Output Signal

• HDMI digital signal is compatible with DVI signal. Most of display devices can support both digital signals. However, some old equipment may have less flexibility in signal compatibility. In this case, user may need to select DVI output format to get normal display in some devices.
• HDMI signal embeds more signal information, such as audio and HDCP. Once some information is missing, it will also affect the display. It may cause intermittent or loss of image. Under this condition, user can try to set DVI output. The connection doesn’t need to change.
  

System Standby and Automatically Turn Off Output

• [Options] [Accessibility] [Standby Time]
• If set [Standby Time] at 60, the system will get into Standby Mode after 60 seconds when no input signal is detected. The output signals from M811L will also be terminated at the same time. If M811L detects input signal again (hot plug signal), it will automatically turn on the system.
• If the projector can automatically turn off/on by detecting input signal, user can control signal source to execute entire system on/off control.

Change Background Color

When no signal input, the system will show blue color background with [Power Saving Mode] message on the screen. User can change background color to black on the screen with no text message on it through [Options] [Accessibility] Black Screen] [On]

Turn off splash screen Logo

• Use can turn off splash screen Logo through [Options] [Accessibility] [Logo Time Out] and set the value at “0”. Default setting is 10 seconds.
• It will reduce the boot up time.

Trouble Shooting

Front Panel LED indicators

• User should see Input / Output LED lights in each channel. If no light illuminated in specific channel, please check Input / Output connecting cables, signal source & projector in that channel.
• If user sees continuous blinking in some channel LED, it means OSD may be locked. Please press [Menu] key for 5 seconds or press 850 number keys in remote controller to disable [OSD locked].
• If user sees blinking LED on Input/Output LED indicators at the same time with 1 second interval, it means the system gets wrong FW/MCU code or HW failure. User can turn off/on the system again to see if it can solve the issue. User can also update the MCU code and FW through GUU PC tool.
  If the issue is still existing, user needs to apply RMA and send back the unit to factory for checking.

No image in the projector

• If user can’t see the image, please click [Menu] key to activate OSD. If user can see normal OSD, the system should be normal. Please click [INFO] key to check input and output timings.
• If user can’t see the OSD, please change signal source, HDMI cable or display device to find the root cause of the failure.
• HDCP may be the reason for no image. Please make sure display device is HDCP compliant.

Intermittent or Loss of Input Signal

• Check the HDMI cable quality and make sure all cables are fitted correctly. 4k/60 signal requires high speed certified cables.
• Cable length: Connecting cable length should be as short as possible. Replace a short cable to verify the possible root cause.
• HDCP compliant issues: If the input source or the monitors are not HDCP compliant, it is possible to stop GeoBox from negotiating HDCP link and show intermittent, abnormal or no image. Please check HDCP condition in signal source or display device.
• Resolution issues: check if signal source and connecting cables can provide source signal supported by GeoBox.
• DVI/HDMI signal compatibility: some display devices may only support HDMI or DVI video signal and execute wrong signal format detecting. The default output is HDMI. User can change output with DVI format through [Options] [Setting] [DVI] [On].
• Usually, to swap with different cable, output channel, signal source and projector can verify the root cause for the failure.
• User can connect a monitor at the end of the Loop out port to check signal source stability.

Video quality issues

• Use the highest resolution and number of color bits (RGB 4:4:4) images allowed by M811L to be used as a signal source whenever possible. Please click INFO key to verify input/output resolution.
• There are a number of lower-quality AV players, the specification and actual output are difference, or because of the use of lower color sampling bits or poor image compression technology, resulting in lower quality or image is not smooth (LAG).
• If the use of H.264/H.265 compressed files, please select a player with hardware decoding to get smooth video quality.
• If the input signal is interlaced signal (interlaced-1080i), and the image is rotated, then the channel will have no [3D Motion adaptive de-interlaced] processing function. If user applies static image source, the output video will have a slight jitter phenomenon. The processing channel quality will be reduced. Use a progressive signal source setting (1080p/2160p) whenever possible.
• Please press [INFO] shortcut key to check the input/output signal settings.

Power ON/OFF by IR controller

• When the system is power off by IR controller, user needs to power on by IR controller as well. If user power off/on directly from power switch, it will not work.

System Crash and Malfunction

• After FW update, please reset the system through a pin inserting to reset hole on the back panel for 5 seconds to avoid abnormal settings inside the system.
• When the input source is 4:4:4 PC graphics signal, only [Brightness], [Contrast] and [Sharpness] three items under [Picture] menu can be executed. If the input is YUV video source, all the items are functional.
• When implement [Corner Wall] alignment, other geometry functions will be not functional.
• Remote controller may be interfered by environment and can’t be smoothly operation.
• When geometry alignment is over the maximum adjusting range, the system may crash. It can be recovered by decreasing adjustment range or system reset
