3 Ways to Display Your Raspberry Pi On a Monitor Or TV

muo rpi overclock intro   3 Ways to Display Your Raspberry Pi On a Monitor Or TVBack in the 1980s and 1990s, home computers didn’t rely on dedicated monitors to display operating systems, applications and games. In those days, things were far simpler. Instead of paying extra for a monitor, the majority of home computer and console owners were happy to use their televisions. It might seem odd now, but 30 years ago people thought little of ignoring TV programs to play video games.

For some, the situation hasn’t changed all that much, with games consoles often connected to the family TV. But as far as computers go, the PC model of a dedicated monitor was eventually widely adopted. It would be unusual to see a home PC connected to a television, even if it isn’t impossible.

If you think about it though, the option to connect to different types of display unit is pretty flexible. This must surely have been in the minds of the Raspberry Pi developers when they were deciding upon how their users might use the computer. Despite its modest dimensions, the Raspberry Pi supports three methods of visual output, enough to cover pretty much any domestic display unit.

What The Developers Say…

When I spoke to Raspberry Pi Foundation co-founder Eben Upton recently, he explained that the stripped down computer was borne from the spirit of the 8-bit era.

“It’s a very cheap Linux PC, device in the spirit of the 1980s, a device which turns your TV into a computer, plug in to TV, plug a mouse and a keyboard in, give it some power and some kind of storage, an operating system and you’ve got a PC.”

Three different connections are supported from the Raspberry Pi – HDMI, VGA and RCA. Yet the device only has two connections, HDMI and RCA – so what is going on? How do you connect a Raspberry Pi TV display?

It’s Got HDMI!

One of the most exciting things about the Raspberry Pi is that it comes equipped with a HDMI connector, meaning that anyone with a HDMI-compatible TV (which is the majority of people in North America and Europe) can easily connect the device to their living room television with an inexpensive cable.

Of course these days, many families have televisions in ancillary rooms and bedrooms, many of which are flat screen devices usually equipped with a HDMI connector.

Along with the SD card and power supply, the HDMI cable is one of the most important pieces of equipment that you can use with your Raspberry Pi, which means that in theory you can connect it to a wide selection of televisions and even modern desktop computer monitors.

Sadly, not all televisions and monitors have HDMI connectors.

Using a HDMI To VGA Adaptor

In the event that your chosen display unit doesn’t have an HDMI connector, the first thing you should do is check whether or not it has a VGA connector – the D-shaped connector that has been commonly found on computer monitors for the past 20-plus years. If your monitor is VGA-compatible, then all you will need is a HDMI to VGA adaptor in order to use your Raspberry Pi with that device or cable type.

You will also need to make a small change to the config.txt file that Raspberry Pi uses when it boots.

Using a memory card reader on your desktop computer, insert the Raspberry Pi SD card and open config.txt in your preferred text editor.

Look for the following lines:

#hdmi_force_hotplug=1
#hdmi_drive=2

Both options need to be enabled, which you can do by removing the hash symbol and saving. These options enable VGA output through an HDMI adaptor and sets the screen resolution to a low 640 x 480.

If you want a higher resolution Raspberry Pi TV display, remove the hash symbols from the following lines:

#hdmi_group=1
#hdmi_mode= 4

You will also need to edit these two lines, changing hdmi_group to 2 and hdmi_mode to 16. Remember to save your changes before safely removing and replacing in your Raspberry Pi.

Display Output Using RCA

A third option for displaying output on the Raspberry Pi exists – the RCA connector. This is found on the opposite side of the device to the HDMI port, just next to the audio port.

Using a standard RCA cable you can connect your Raspberry Pi to any compatible TV or monitor (the vast majority of those produced in the last 25 years), although note that as soon as an HDMI cable is connected the Pi will switch to that output.

Depending on your screen resolution, you may need to alter the way in which the Raspberry Pi displays windows. This will affect you if the monitor has a low resolution, but by changing the overscan settings in config.txt you can configure the video output to suit your monitor.

Conclusion

The Raspberry Pi continues to be a remarkably flexible device, surprising users in so many different ways. I had mine for several weeks before I discovered the RCA port (to be honest, I was too busy playing with operating systems and software) and the news that HDMI to VGA adaptors can also be used is just another reason for anyone who doesn’t already own the Raspberry Pi to head out and buy one.

When my Pi is not headless, I have it connected with HDMI to my HDTV that I use for a monitor for my desktop. 37″. But, mostly, I use it headless. and once IO have all the sensors set up to it for weather, it will be out in the shed, in a container, logging the data and sending it to CSOM.

Are you on crack? (You apparently know nothing about computer h/w “back in the ’80s and ’90s”.) Unless you were one of the few people using WebTV or something like, *EVERY* home computer used a “dedicated” (CRT) monitor for a display. Now, there were some game consoles that attached to the typical TV (for Pong et al), but computers… same then as now.

“Are you on crack? ”

Nice start, polite, tactful, etc.

“(You apparently know nothing about computer h/w “back in the ’80s and ’90s”.)”

I’m 37. I got my first Vic 20 in 1981, and a Commodore 64 in 1984. I could go on, but you’re boring enough without me making matters worse.

“*EVERY* home computer used a “dedicated” (CRT) monitor for a display. ”

I’m also British. Go research. That didn’t happen here, not for computers nor consoles.

Or, just perhaps, you’re the one on crack.

But seriously, don’t jump onto a post with such aggression and rudeness.

Hi I am new to the PI! i just got yesturday as a matter of fact. Now My question is can I setup duel monitors with the PI since it has output for rca/hdmi. I have a flat screen that has rca inputs and a flat screen vga that I would like to split the PI between the two.

And by the way that guys comment was rude. I am a year older than you christian and I remeber my friends having the atart computer and commandor hooked up to reguler t.v.s

Hi Gary

As far as I have been able to tell, the Pi will use HDMI or RCA, but not both at the same time.

http://plugable.com/ sells usb graphic adapters that might work. Be sure to contact the company first and ask if they will work with the RPI before you order.

Mike

I had a ZX80 and later a Commodore 64 both of which required a TV to function. Maybe that guy was talking about office machines. Nevertheless, a rude post.

JD

good answer lol

It is sad to see those kind of comments everywhere. Internet moved people’s standards way too low. I’m not british but I worked with Sinclair computers all through the 80s and beginning of the 90s.

Thanks for the post. I was trying to figure out how to build an arcade machine with the Raspberry using a simple CRT monitor. Now I know :-)

Frederick Blosser

Glenn, that was a very rude comment. *EVERY* home computer did
NOT all use a “dedicated” (CRT) monitor. The Commodore Vic and
64 did not as Christian mentions, and the Atari computers did not, and
many more early computers did not use a “dedicated” CRT. Just
because you don’t know the historical facts doesn’t give you the right
to be rude. Let’s have a little civility here.

CuriouslyYellow

All of my early home computers used a tv output, in 35, and agree with Christian!! My first monitor was bought a long time after my first computer….fairly sure my oid spectrum looked good on the TV

>Are you on crack? (You apparently know nothing about computer h/w
>“back in the ’80s and ’90s”.)

Kind as that may be, you forget Apple I and II, TRS 80, Coco, Commodore 64, Sinclair… I could go on… And, before you ask, no, I’m not on crack.

I am wanting to have a goat several projects using Raspberry Pi and the more technical information information that I receive from an article like this I’m sure will not only make me more comfortable in using it but will lead to some of own ideas.Bring on more Pi.

Rameez

Hi there ! I just wanted to know if i’ve ruined my Raspberry Pi, Model B 512 Mb, as I used it on a TV supporting RCA connector. I used it while I also removed the SD Card cuz, nothing happened when I turned the TV on the COMPOSITE MODE. And also, I have copied the image of RiscOS on the 2 GB SD drive using the external card reader and LiLi USB Creator.

Now I want to say that, Nothing happens, only the red light on the pi standby and nothing else happens ! No video or screen or anything is detected by the TV screen. Tell me what to do, please ? I AM NEW TO RASPBERRY PI, SO PLEASE HELP…PLEASE !

Christian C

Hi Rameez

You’re unlikely to see anything unless you have a working image on the SD card, as everything boots from the image – there is no BIOS screen that you can easily access, for example.

Make sure your Rasbian (or whatever OS) image is correctly written and use the best quality SD card available. To be honest, as good as RiscOS might be you should probably use Raspbian if you’re new to the Pi just to get to grips with the device rather than the OS.

See our getting started guide for some Raspbian details: http://www.makeuseof.com/tag/started-raspberry-pi/

TroubledPi

Hi! i need help here..
i have a raspberry pi connected with the following layout.
didn’t want to buy any other cable yet, so i was testing out with what i’m able to grab around me. however it does not work.. :(
Raspberry Port -> [ HDMI (male) -> DVI (male) ] -> [ DVI (female) -> DVI (female) ] -> [ DVI (male) -> VGA (female) ] -> VGA Cable to Monitor.

i don’t really think it will work in the first place, just trying my luck wondering if theres anything in the config file where could go about it.
need help please! Thanks!

Christian C

Hallo! I should stick to RCA and HDMI as it was meant to be if you’re looking for some success. AFAIK, there are no settings to change things to allow the above cable config.

brian

you could theoretically (i dont have a Pi yet) use a USB to VGA adapter. i know they work in windows, and i assume linux, but that is also an option. you may be able to run multiple monitors that way.

HL

Talking about all this old hardware makes me remember the composit video to rf modulator so you could connect it using the antenna connector. Anyone tried that?

wdwd

Crack? Now there’s a throwback.
