To meet the needs of installations that require electronics to have isolated ground the following LCD controllers have been designed with this as an option. Enabling the option means that the mounting holes are no longer connected to ground of the controller.
LCD controllers providing the isolated ground option are:
- SVH-1920v2 and HE-1920v2
- SVX-1920v3 and HX-1920v2
You can see a summary of all our LCD controllers with a link to specific web pages here. HE models are designed for harsher environments and typically have conformal coating and provide enhance vibration and temperature resistance.
In contrast to the consumer market where everyone is used to seeing new models every 6 to 12 months many Digital View customers look to us to keep products in production for as long as possible. The SVH-1920 is a good example, first launched in 2005 it was kept in production for 10 years until we were unfortunately forced to discontinue production due to serious component issues.
However to meet continued demand Digital View has released the SVH-1920v2, it is almost identical to the original SVH-1920 but features an updated scaler as well as new panel connectors so as to meet changes in the LCD panel market over the years.
Here is a picture of the two boards (click on the image to see a larger version):
Compared to the original, the SVH-1920v2 provides:
- 10 bit color support, the original provided 8 bit
- Updated LVDS connectors
- eDP panel support
- 18 PiP options on the v2, there were 3 on the original
- Ceramic capacitors
- A different color PCB.
Samples are now shipping, for availability and technical questions please contact your reseller or contact us directly.

The following Digital View LCD controllers have been updated and Revision Notes posted to their web pages:
For more information please see the Revision Notes from the respective product pages.
The Digital View Windows based Controller Utility software has been updated to version 1.02, the principle modification being to add support for the ALR-1920 LCD controller. It is available for download here.
The Controller Utility provides a graphical user interface for many of the RS-232 commands supported by the following Digital View LCD controllers:
- ALR-1920 (start from V1.12.00 firmware)
- SVH/HE-1920 (start from V0.48.00 firmware)
- SVH-1920+ (start from V0.27.00 firmware)
- SVX/HX-1920 (start from V0.10.00 firmware)
- SGX-1920/HG-1920 (start from V0.39.00.00 firmware)
- SGX-1920L (start from V0.50.00.00 firmware)
Furthermore it enables replication of settings from one controller to another.
Not all functions are available for use with all controllers, for example the ALR-1920 does not support the extensive gamma control functions supported by the SVX family of controllers. Also the newer SVX models, SVX-1920v3, SVX-2560 and SVX-3840 are not supported as yet, these will be added in an upcoming release.
All Digital View controllers support a comprehensive and consistent command set though the specific commands supported depend on the functionality of the particular controller. In addition to communication via the RS-232 interface the command set is also supported via Ethernet on some models such as the SVX / SGX & HX models.
The webpage for the Digital View SVX-3840 LCD controller for 4K Ultra-HD LCD panels has been updated to include the manual and 2D and 3D drawings as downloads. See here for details.
The SVX-3840 is a feature rich controller model supporting 10 bit LCD panels with a resolution of 3840 x 2160 pixels. The 8 or 16 string V-by-One panel connection supports both 60Hz and 120Hz LCD panels from Sharp, AUO, LG, Samsung and Innolux. For dedicated use with a 60Hz panel the SVX-3840
Inputs for 4K include HDMI and DisplayPort with other inputs such as VGA and DVI for lower resolutions.
Non-consumer 4K applications are continuing to increase as the cost decreases and people recognize the benefits of higher resolution. We have seen digital signage, corporate AV and retail applications all making use of the larger size 4k LCD panels of 65″ and up. As more smaller size Ultra-HD LCD panels become available there will be an increase in medical and broadcast display requirements. Overall as 4K becomes more widely adopted the display requirements will extend into many other market sectors as well.
A common comment has been about the lack of 4K content however this is primarily a consumer market issue. In the commercial market we have met many creators who work exclusively in 4K producing considerable amounts of Ultra-HD resolution video. Most non-consumer applications can source or create suitable 4k content to meet their needs.
We have already verified connection with quite a few LCD panel models from different manufacturers, if you have a particular requirement please contact us via our contact page.
Update 13 Mar 2015: Here are the 4K LCD panels already tested:
- AUO 55”, 3840×2160 (60Hz), model P550QVN01v0
- AUO 65”, 3840×2160 (120Hz), model P650QVN01.0

- LG 84”, 3840×2160 (120Hz), model LD840EQD-SEM1 (LG 98″ also supported)
- Sharp 70”, 3840×2160 (120Hz), model LQ695R3xxxx
- Samsung 75”, 3840×2160 (120Hz) model LTA750FJ01
Update 17 Mar 2015: Modifications to the Specifications page to clarify panel and input signal support. See here.
In Q2 of 2015 Digital View will be releasing an LCD controller supporting HD-BaseT called the DD-1920-HDBT. Details are preliminary at this stage but the advance specification is:
- Input type: 1x RJ45 (HDBaseT interface) supporting Cat5e or Cat6 up to 70 meters (230 feet)
- Panel Interface: LVDS (dual channel)
- 8-bit panel output
- On board RS-232 control interface
- IR remote & OSD control
- Backlight control: DPMS, analog or PWM, serial port
- Audio line out (stereo)
- Power input: 12VDC
- Optional On board LED backlight driver
- Board size: 107.44mm x 91.44mm (same size as the ALR-1920)
This will be HD-BaseT standards compliant and compatible with other compliant equipment however we will also be releasing an HDMI to HD-BaseT converter and transmitter board to provide a complete end-to-end solution. The cabling requirement is Cat5e or Cat6.
Although HD-BaseT is not an IEEE recognized standard it is becoming increasingly popular for installations requiring an extended video source cable and is supported by many AV extender and device manufacturers for the commercial market. We see it as being suitable for many installations such as digital signage where the video source may be centrally located to feed multiple displays around a retail store or sports bar.
As a note, the standard provides for video, audio, Ethernet, control and power with HD-BaseT2.0 supporting 4K – the DD-1920-HDBT will concentrate support on video up to Full-HD as well as stereo audio with a view to additional functionality being implemented on more advanced controller models in future. Digital View can also implement HD-BaseT on a custom engineered basis for OEM customers.
If you would like to know more about Digital View support of HD-BaseT please send an enquiry to our sales and support team here.
The SVX-1920v3 LCD controller, designed for input signals and LCD panels up to Full-HD and 1920×1200 resolution, was recently updated with firmware v1.12.00.00 enabling many new functions for this model. These include:
- Support for SDI input adaptors, HD-1000/2000/3000
- Picture-in-Picture support

Here is a quick look at the Digital View LCD controller product families for 2015…
- All models feature built-in multi-panel support (dip switch selectable), consistent RS-232 & Ethernet commands, consistent panel signal and other internal cable connectors* (see note).
- SVX for LCD panels with resolutions up to 3840×2160 (4K Ultra-HD), these are feature rich, fully memory buffered controllers enabling a function such as video-lock ‘off’ (explained here), Ethernet & serial RS-232 control, Picture-in-Picture. Ideal for sophisticated display systems and high quality video displays.
- ALR are cost effective models supporting panel resolutions up to 1920×1080 featuring low latency and RS-232 serial control. Ideal for general commercial monitor applications.
- DD these compact LCD controllers are single input connection type such as VGA, DVI, HDMI, DisplayPort with more versions coming soon. These are designed for higher volume applications, these models have a MOQ.
- HE models are designed for harsher environments, they are based on SVX and ALR models but enhanced for higher temperature tolerance and with conformal coatings.
For a complete summary of current models please click here.
* Note: With the introduction of the ALR-1920 family, DD-xxxx models and new SVX models we have transitioned to a new generation of LVDS connector and OSD cable connector. An exception (proves the rule – right?) is with the RS-232 and IR connectors where we use two types depending on model.
The new SVX-2560 LCD controller with scheduled availability in January 2015 is now live on the Digital View main website, click here for details.
In addition to support for LCD panels and input signals with a resolution of 2560×1600 and 1920×1920 the SVX-2560 offers support for 4K Ultra-HD input with downscaling to 1920×1080 for Full-HD LCD panels.
Other advanced features include image flip (horizontal & vertical) which is good for teleprompters and similar applications, sensor monitor and fan control in addition to the normal suite of Digital View LCD controller commands over RS-232 (serial) and Ethernet suitable for digital signage applications, as well as dual digital Picture-in-Picture (PiP).
As discussed in the previous blog article the SVX-2560 with its full frame memory buffer supports turning video-lock off meaning that the output frequency to the LCD panel is decoupled from the input frequency. The memory buffer also enables functions such as image overlay markers and more advanced color and image management.
Sometimes the solution to a display noise issue can be elusive. For example it may look like a cable or system noise issue or a firmware related panel signal mismatch. Or it may be simply a signal timing issue resolved by turning off video-lock.
So what is video-lock?
Video-lock is when the timing of the output signal to the LCD panel is locked to the timing of the input signal. So input a signal of 50Hz and the result will be an output signal to the LCD panel of 50Hz.
Conversely if video-lock is turned off, as is possible on Digital View’s fully memory buffered boards such as the SVX family, then the LCD controller can provide an output timing different from the input timing. This output timing can then be matched to within the tolerance of the panel’s input signal.
How might this be important?
As in the example above if an LCD panel has a timing range that doesn’t match the input signal the LCD controller it will be necessary to turn off video-lock so the LCD controller can deliver the correct timing to the panel irrespective of the input signal timing. In some cases this might be obvious such as in the case of a 50Hz input signal where the panel has only narrow tolerance around 60Hz, however we have seen other cases where both input signal and LCD panel specification may be noted as the same but for some reason don’t match but turning video-lock off resolves the issue.
When would you want video-lock on?
In most case having video-lock on is appropriate as it will ensure the LCD display scans at the same rate as the input signal which will prevent shearing artifacts in panning video.
An LCD controller with full memory buffer offers other benefits such as the ability to manage and enhance the image, motion compensation and better de-interlacing as well as support for a wider range of input frame rates.
The full frame memory buffer such as in the Digital View SVX family of LCD controllers does introduce additional latency as the image has to be loaded into memory for processing, approx 16~20ms. If near zero latency is required then LCD controllers like the Digital View ALR-1920 and ALR-1400 are suitable with approx <0.3ms.
