i am shooting with the xha1 + sgpro rev3...
i really need an external monitor to see if the picture is sharp, i think an ikan monitor is not so bad? do you know an alternative HD monitor??
7" with batteries?!

An alternative is making your own. Im doing it because:

1. 1440x234 isnt good enough, 800x600 is "nah nah" but not 100% and higher res ones cost shitloads of money :)

2. I like to build stuff.

If you willing to build a case and a little extras for the panel-kit you will have kit for around $400 with a 7.2 " 1280x768 panel. Dont know which connections you need, but this alternative only features hdmi, vga and component. The rest of the money is up to you, its all in the design of case and so on.

Any info besides links to pictures of the monitor?
 
First of all, what is your budget? It's really a case of getting what you pay for. Cheap monitors like Ikans I don't really like as the build quality is terrible and the image isn't that great; useable, certainly, but not my first choice. The best bang for the buck monitor IMO is the Carrion monitor, but with everything you need to make it work it'll run you in the neighborhood of $2200. Then midway is the Marshall, Varizoom, Nebtek monitors.
 
yes thats a really big point, i have a budget about 800 dollar
thats not so much, so i am looking for a monitor in this section
 
The picturequality is insane :) Compared to a generic 10" 800x480 and the Varizoom 7" tft this one is soooooooooo much better.

Not something to think twice about if you feel like making the case yourself, then youll have a kickass monitor in the end.
 
The only problem is the power requirements of those LCD boards. I got that same Manhattan board linked above and I'm still figuring out how to power it with stable 5V and 12V from single battery. (maybe this m3 atx PSU will work off the batteries but I haven' t received mine yet)
By the way did you know that the standard PC VGA ports can take component video signals? I´ve used 720P component signal to standard VGA and it worked well.
 
Why do you need 5v? =)

It only use 12v for the board and then 24v for the backlight? OR its just the board for another panel that need 5v?

I plan to convert an old canon charger later on, the ones that does BP-XXXXX
and fit a 4000mAh battery on it.

As it is now ill just use a single ledbattery and go like this:

12v>board 12v>convert to 24v> to backlight.

And later itll be 7.2 > convert to 12v converted 12v > convert to 24v

Powering this stuff is the least of the problems, lots of circuits to use.

If the pictured MST board is from Pixelworks it will require +5 and +12V and it has it's own power supply circuit for backlight that connects to the main MST board and to the backlight. This Pixelworks board btw can be connected to a additional panel that will give you all the other imaginable AV inputs inc TV antenna but it doubles the size.

I dont know about that but I just put 12V to the board and 24V to the backlight itself and it works flawlessly :)


And the case is just a quickrender :) So it doesnt excist just yet =)

How do you power that Pixelworks controller? Is it straight 12V and no +5 as I don`t see that connected on this board of yours. If so how it tolerates the voltage drops as the battery slowly discharges?

Thanks,
T
 
No ilarger tests yet, but its straight 12V from a 7.2Ah battery. I dont plan to use it that much so it drains it but it should work fine.
 
A little push to this thread.

My 7.2" screen running of a single 12V battery now

So no issues running this12V and 24V monitor off a single 12V battery.
 
Oddname, there must be something different in our pixelworks board as power LED even won't lit up without +5 connected and mine doesn't have that green onboard led. By the way how do you feel about 1/8th of the screen width cropped off? Mine still has some really heavy blue cast and I'm running 12" Toshiba with Pixelworks controller. There are no free lunches.

Havent really tried it fully yet, I just hooked up and run. Ill see what issues it has later etc etc. The picturequality so far is amazing :)
 
Looks nice Oddname.
Where did you get the 12>24 step-up?

DIY-beamer seems to be out of 7.2s :/
