LLC-1920 Ultra Low Latency

Close to Zero Latency

From HDMI signal in to LVDS signal out: 0.00054ms.

We have been providing latency results for over 10 years now, some models have been very fast. But now we have a new model that is ultra fast…

The Digital View LLC-1920 is an HDMI-in, LVDS-out LCD controller board for signal and panel resolutions up to 1920×1200. The latency of this board compared to a few other models is shown here:

• LLC-1920: 0.00054ms
• ALR-1920: 0.0186ms
• SVX-1920v3: 19.6ms

Measurement Method

The above measurements use an oscilloscope to measure the time from the HDMI signal input to the LVDS signal output, purely for the controller board, ie no panel.

Our normal method for measuring and stating the latency is to use a meter from Leo Bodnar, that sends a video signal to the controller board and then measures how long it takes to show on the LCD panel. So it will always give a longer latency figure than the oscilloscope method, the panel adds latency.

LLC-1920 Introduction
