Awesome, inexpensive 7" monitor!

On eBay I've found several inexpensive "secondary" screens for the Insignia NS-D7PDVD. This monitor is just awesom if you are looking for a small -but NOT too small, portable, TFT composite color monitor. The seven inch size just blows away anything smaller -you can actually see the content to be workable without squinting! The colors are great, the switchable screen aspect ratio, and especially the built in speakers ---AND THE PRICE, easily makes this your best choice for the cost range.

I'm using mine as the portable monitor for Raspberry Pi. I teach two Unix/Linux classes with it. I most highly recommend Raspberry Pi owners to give this monitor a real hard look... and then buy it!.

Hey,

Just bought one of these monitors off of Ebay. I am hoping that it is not broken and maybe I am missing something. What power supply are you using for yours? I have tried a 12v 800mA power supply and got it to light up ones with a blue screen. Nothing from the raspberry came through the screen. Then tried 12v, 1500mA. Could not get a screen at all. When yours has nothing plugged in, what kind of screen do you get? I am really hoping to get this to work, so far it has been a disappointment. Any help greatly appreciated.

Thanks!

For those who go this route for a monitor. 9v 1500 mA power supply works fine. For the price... the monitor is good. But you get what you pay for. It is not the greatest screen by any means.

I'd really appreciate if everyone is honest about a product and not plugging their own with phony aliases... (Not saying that this is such an example but it'd be a schoolbook classic ;) )

In the end of the day you get what you pay for - no more, no less.

I work professionally with Android HW/SW graphics at one of the biggest phone manufacturers and I can spot an "Awesome" panel easily and they never fall under the category "inexpensive".

If you want to play around with descent quality then you have to spend a few quid as well - or be a helluva scavenger in various skips etc... (I still can't resist a skip-dive at my age :p)

Please keep the forum free from sales pitches and similar... (unless you contribute with code/libraries/demos/SDK's for your hardware - at reasonable price)

That's my view anyway and if you want a descent 10" panel with touch capabilities - which is what everyone want today - you simply can't find anything under 100$, unless you're really lucky.

Professor Harris,

Could you please comment on how you set this screen up, modifications to the config.txt file, etc? I picked up one of these and the quality of the display is, in a word, terrible. Quite blurry.

So far, I, too, would put this device in the category of you get what you pay for unless you have configured it using something other than the defaults.

Thanks.

Hi all,
There is an HDMI to VGA adapter available for $10.43 US - free postage. Surely this is a cheap option.
Can be found on ebay.com. I hope this will help those who have a limited budget.
Cheers

Hi,
Re my post regarding the $10.43 HDMI to VGA adapter - It would need a mod done for it to be usable.
The adapter runs off the raspberry pi and it would need a separate power supply connected.Easy enough to make if you are into electronics or else a separate plugpac with a USB output.Requirements
5 volts@ 1 amp.
Cheers

Yep same problem. Its usable... but i would rather not strain my eyes. I invested alot more than I should have in the monitor. Its just not worth it. Save the money, get something good.
