Thread: DWW-750J Motorized Screen-Full Review

UPDATE: One other item of note that I have noticed with this screen is that it does not seem to have any form of onboard memory to save your settings once it closes. So as is mentioned in this thread, it will always open to the same position, and at the default brightness.


Ok, so as promised in another thread, here is my review of the DWW-750J. If anyone else has one of these units, please post your reviews, opinions, etc... in here.

OVERALL RATING: 8 out of 10. Very Good

Ok, so I received my new DWW-750J in the mail today. Marina at Digital World Wide has been wonderful helping me out with my less than adequate DWW-700M. So thanks again for all your help. According to Armen it uses the same Hitachi LCD panel as the Lilliputs, but a different VGA controller. Which I hope means that it won’t be subject to all the problems I’ve read about the Lilli’s. Now on to the review:

After opening the box I found the following:
-DWW-750J Screen
-TouchKit 3.1.5 CD
-Barrel connector for power
-Remote
-Antenna for TV tuner

There was no manual included. After talking to Marina she said that the unit doesn't come with one, but Armen is working on writing one for it. (this may be the reason it's not being publicized much right now on their site, but that’s just speculation on my part)

A manual would be very helpful because the unit is laid out a bit odd.You can see the back of the unit in this picture. I forgot to take my own pictures before I installed it, so we'll work with Armen's.


First Impressions:

The unit feels much more durable than the 700M, and is all metal construction instead of the plastic front that the 700M has. One thing that struck me as a bit odd is the absence of a back plate. Not a big deal really, just strange. Another odd thing is that the TV tuner card (not shown in the pictures) actually sits on top of the unit with sticky tape, and has a ribbon cable attaching it. I assume this is because it was added in later when it was too late to put the whole card inside the unit. This is a bit cumbersome, but not something terrible IMHO.

The USB cable is hardwired into the unit itself but all the other connectors are plugs on the back of the unit. Power is supplied through the barrel connector. Red to battery+, Black to Ground, and that funny yellow wire that is hardwired to the unit goes to ACC. This is where a manual would have come in handy, but after a bit of tinkering I figured it out.

The unit has a VGA connector, S-Video input, Composite input, and what I'm assuming to be a stereo pair of audio Outputs for the TV tuner. There are also three 1/8" Mini Jacks on the unit that I'm not sure of their use, I'm waiting to hear back from Armen on that.


So I went out to the car after figuring out the wiring of the unit and started the install.

Installation was a piece of cake. You have more depth for the screw holes on the sides than on the 700M, which meant I didn't have to worry about finding or cutting short screws again.

Once installed I started to tinker and figure the unit out. The front panel of the unit looks like this. The buttons are a bit sensitive and it is real easy to double-clutch them. This unit does offer an Auto-Open/Close function, which is controlled by the "Manual/Auto" switch. When set to Manual the unit opens and closes only but pushing the open/close button. When set to Auto the unit opens as soon as that ACC line has power, and closes approximately 5-10 seconds after it looses power. The screen stays on after you close the unit if there is still a signal which seems a bit odd, but the unit auto-powers down if the signal disappears, and auto-powers on when it receives a signal. This can be disabled by just turning off the power.

I know that I've been mentioning a lot of tiny things that aren't so great about the unit, but they are tiny things. Now to all the good stuff

The motor used in the unit is much more solid, and powerful. It opens and closes smoothly, and quickly. I LOVE that it turns side to side. Although it's a manual adjustment, it makes viewing SO MUCH EASIER.

It's much less flashy than the 700M, and on that note, there are no annoying LED's that stay on all the time or any crap like that. Although I did like having the Clock since I had to take mine out for the top screen.

The image quality is superb. with a great viewing angle, and the colors are very vibrant. It is just as bright as the 700M, but not washed out, and the "brightness" adjustment actually adjusts the backlight and (I think) the LCD "brightness" together instead of leaving the backlight at full like the 700M.

The Touch screen is very responsive, accurate, and stable. It's not having any of the issues that I had with the 700M like loosing calibration, totally quitting, EEPROM errors, etc...

I have not yet tried out the TV tuner or the two video inputs, so I can not comment on these.

Overall I really like the unit. It gets an 8 out of 10 from me. Only loosing points for the small weirdisms like the backplate, not shutting off the LCD when closed, and TV Tuner being outside the unit. I would recommend it to anyone looking into a motorized 7" TS.

I will post again after about a week or so of use to add any other thoughts or things that show up.


Again, please post your own thoughts on the unit if you have one. I would like to hear what other people think

Here are a few pics of the unit installed. I had to cut a tiny bit to make it fit, but not too much. I had the brightness turned down to 15 for night driving.
