You need one RPi per screen there is only one output HDMI interface so it can ONLY drive one HDMI device. You can then use software to divide the image into segments and spread it across each RPi.MrMax wrote:
How do you add more than one screen to the pi? I know how to connect standard monitors but im talking portable monitors (More than 2). Does'nt matter about size and spec now, the framework comes first.
That would cost more... because you would drop away each RasPi modified that way... and maybe a monitor or two would also be victims of this idea.MrMax wrote:This is going to cost abit more than i thought..
What about modifying the actual Rasbpi board by ripping out say the RCA video port, audio jack and ethernet ports and replacing them with hdmi ports so it can handle 4 screens?
It's not about time consumption... this idea is simply impossible to implement.MrMax wrote:Yeah i agree after thinking about it thats a bad idea, too time consuming etc etc.
I don't expect this to be cheaper (& better) than RasPi multiplication mentioned previously.MrMax wrote:Someone seriously needs to make a hdmi splitter or just a splittter in general (VGA, DVI) with video cards incorpoarted...
The chip on the Raspi only has one HDMI output so that is a no-go.MrMax wrote: What about modifying the actual Rasbpi board by ripping out say the RCA video port, audio jack and ethernet ports and replacing them with hdmi ports so it can handle 4 screens?
These connect to the yellow RCA jack on the RPi. They usually have 2 inputs one is for a reverse camera. If the reverse input is used then you have to connect the reverse signal wire to 12V. Also if you used NOOBS then you may have to do some config changes to get the RCA composite to work.MrMax wrote:Hello ALL,
So from the majority multiple pi's are the way to go. That means i am going to have to de-solder alot of the bulkier components to trim it down, which should'nt be a problem (Fingers crossed).
What about the actual screen's? I have already bought a bog standard one from amazon with no luck of it working.

Ripped it down to screen and PCB but it did'nt work when i tried connecting to it the pi for some reason. Maybe me not connecting it right.
On that note how do you connect one of these types of screens to a rasberry pi? Again any tutotials anyone knows of would be appreciated.
