The Digital View ALR-1920 family of LCD controllers support a subset of DDC/Ci commands to enable a computer to send commands to the monitor through the video port (VGA, DVI, HDMI). The specific Digital View controllers supporting DDC/Ci include:
- ALR-1920 : A low latency controller supporting panels & signals up to 1920×1200 resolution.
- ALR-1920-SDI : Adds SDI connection up to 3G-SDI.
- ALR-1920-120 : Adds 120Hz panel support.
- DD-1920: Designed for higher volume display applications.
Functions supported include:
- RGB color
- Input source
- Power states:
- On = Always on, displays “No sync” if no input signal.
- Standby = Power off to the panel and backlight.
- Sleep = “No sync” message displayed for 10 seconds then backlight off.

In talking with one of our business partners this morning I was reminded of the issue of video signal latency and our solutions for the problem. Video latency is where there is a delay between the source of a video or image and the image on the display. Some of the ways this issue can be seen as a problem include:
- Lip sync, in this case you hear the audio before the person appears to say the words. This can affect video-conferencing systems as well as other digital media transmission systems.
- ‘Cursor delay’, you move the cursor or click a button and the image lags behind the action. This is likely to be an issue when the system is operating over a digital distribution system.
The solution: Amongst our extensive range of LCD controllers (the electronics that puts the image on a flat panel display in a monitor) we have various models that are low latency, of these the most popular is currently the ALR-1920 that offers HDMI and DisplayPort digital inputs.
If you are planning a digital signage display system the following LCD controllers are a great place to begin:
- SVX-1920, the most popular choice as it offers a significant number of functions and control options together with support for DisplayMark display and system monitoring as well as support for 120Hz panels when used with the IE-1000 add-on board.
- ALR-1920, when straightforward full-screen video is required and cost is a key factor the ALR-1920 is a great choice. It is compact and easy to work with and gives excellent results.
- SGX-1920, this is the very top of the range providing all the features of the SVA-1920 plus a considerable number of input signal options as well dual digital input and powerful Picture in Picture capabilities.
