[REVIEW] Lilliput 669HB TouchScreen Monitor

What is it?

The Lilliput 669HB is the latest version of the 669 series. It offers all of the benefits of the 669GL (reviewed here), with the added function of a high-brightness display. See the Lilliput 669HB specifications here.

What’s in the box?

As with most of the Lilliput touchscreen devices out there, the box is packed with everything you need to use the device right away. Included is the 7″ TFT display, an HDMI to HDMI/USB cable, DVI to HDMI/USB cable, VGA/composite cable with sub-connector, home power brick, cigarette port power supply, Remote control, touchscreen driver CD, and instruction manual.


As most of us know by now, the ability to clearly see and control the touchscreen in most car PCs is paramount to the system working as intended. With all of the technical innovations the first-gen 669 series Lilliput carried one gaping flaw in design was the “new” controller board’s ability to only display with 200nits of brightness. This new display, the 669HB (high-brightness) addresses this issue. While its still doesn’t boast the visual quality of the transflective units that are out there, it does have key features that they still lack. The 669HB excels at providing installation flexibility with it’s 4 different methods of signal connection.

While the VGA and composite cable option is still available (and frankly, still viable), the digital connection options (DVI-I and HDMI) allow for users to get the most out of there 7″-diagonal display. The digital connections allow for the bump in brightness to shine through in a greater light than the 669GL provided. Now you can enjoy the crisp colors and sharper contrasts in the daytime!

450nits isn’t the only change from the first-gen 669. Now also included from the factory is the accessory wire which allows the Lilliput to automatically change to the composite 1 connection upon powering. I found it pretty strange that this was excluded in the 669GL considering there are other, older Lilliputs which have the feature, but now it exists in the 669HB and works as described.

The 669HB uses the same 5-wire touchscreen controller found in the 629 and 619 7″ units now, and the uniformity should come in handy when installers look for double DIN options on the market now. The 669GL used a different, oddly shaped board which made the Double DIN frames available incompatible.

The only holdover negative from the original 669 device is the lack of auto-dimming control found on many other Lilliput and Xenarc devices. While this technology generally doesn’t make or break a monitor, it’d still be nice to have so users wouldn’t have to look for alternative means of controlling the screen brightness at night.

The Positive:

• Brightness increase means the 669 is on par with other Lilliput LCDs in the daytime
• HDMI connectivity remains a huge plus
• Auto-Power and Auto-Switching available from the factory

The Negative:

• Still not transflective from the factory (see here for the new transflective version)

The Verdict:

The new version of the Lilliput addresses the one main complaint most people had with the original. The brightness of the display when in direct sunlight is definitely an upgrade over the 669GL, and while the difference may not be enough to upgrade, new potential buyers should look at the 669HB as the first choice in the lilliput product
