Hi, which small small and portable monitors would you suggest to combine with Raspberry Pi.

As Raspberry Pi is part of huge range of different project please suggest which would be best in each of these categories.

  • Home PC
  • Smart home touch screen mounted in the wall
  • Car PC
  • Portable learning device

If there are multiple choices in each category please rate it also by quality and price: best quality and best bang-for-a-buck

Take a look at the Lilliput HDMI monitors. I have not tried them myself but have seen them used in youtube videos about the Pi. –  Steve Robillard Jul 4 '12 at 18:33
    
I was considering this one, £150 is probably as cheap as they come. However, it's practically the same price as Google's new tablets... –  Jivings Jul 4 '12 at 19:53
    
I'm not sure if it would work, and you would definitely need a powered hub. But you could try the Mimo USB monitors. mimomonitors.com/products/mimo-720-s –  Kibbee Jul 4 '12 at 19:57

I think you have to decide what matters most to you in the monitor.

Do you want:

  • The highest resolution possible?
  • Easy portability?
  • A mountable screen?
  • An articulated monitor arm?
  • Battery/DC/AC power?
  • HDMI/Composite input?
  • Touchscreen functionality?
  • On-board speakers/sound?
  • An inexpensive solution?
  • A warranty?

The answers to these questions will help you to determine where and how to search for your monitor.

Some options:

Portable DVD players/Second DVD player screens/Portable TVs

Some portable DVD players, car rear view mirror camera screens, and portable TV screens have composite inputs. They are made by a large variety of manufacturers. They often have built in speakers and sound inputs. They may or may not come with car/AC adapters. They may have included batteries. The resolution is usually much lower than comparable computer monitors. Verify that the screen has composite input, and then verify if the connectors are on the device, or if the composite A/V input requires some sort of "AV-in" conversion cable. Re-purposing these screens for your Raspberry Pi may save you some money and still fit your needs.

Professional photography/videography screens

Some monitors have been created for use in digital photography and videography, such as those made by Lilliput. They usually have an internal/external battery and often have HDMI input, and have the option of sun shades to deflect sunlight, as well as mounts (usually for being mounted to a camera or tripod. The resolution and brightness may be the best you can find. However, the price is quite a bit higher than some of the other monitors available in this size.

Car PC / Carputer monitors

There are also a fair number of "carputer" screens, some of which have DVI/HDMI input and even touchscreen functionality. The cost for these screens is higher, and the touchscreen may or may not be easy to set up in Linux, and they may only accept DC power natively (due to being designed for use in cars) but it may provide you with a more complete solution when all is said and done.

Standalone monitors (USB)

The next set of monitors to look into would be the standalone USB monitors, such as those made by MIMO and Lilliput. Upon first glance, they seem like the best option, because they only require USB input, but display drivers may be hard to come by, and the Raspberry Pi may not be powerful enough to feed the screen the power it needs.

Small computer monitors/touchscreens

Some small computer monitors or touchscreens also exist on the market, mainly by Mimo and Lilliput again. Some of these monitors have touchscreen functionality. These are differentiated from professional photographer screens by their lack of battery power. Driver support for touchscreens may work, or may not. Tread carefully. These monitors tend to be on the more expensive side, in general.

Conclusion

If price didn't matter to me, I probably would have purchased one of the Lilliput monitors, but price does matter to me, so I didn't. I ended up deciding on a DVD "second screen" that had an included mount and AC adapter on eBay. second screen Sound inputs are included, and it has AC power. I don't plan on my usage requiring anything too fancy in the resolution department, and I was looking for the most cost-effective way to get my Raspberry Pi running. Getting it from ebay meant that I paid a pittance ($20), but I had to lurk around a lot of different auctions to find it at that price, since they're usually closer to $50. This also means that I don't have a warranty and I'm purchasing a product more or less sight unseen, so I may not have the image quality that I was originally hoping for. In my case, it worked fine when I hooked it up, as evidenced below: running the Pi

It all depends on what you value most in your screen. Your mileage may vary.

Awesome answer. –  Alex Chamberlain Jul 6 '12 at 15:18

@AlexChamberlain Thanks. I've had a couple months to think about this while waiting for my RPi to arrive. –  Zoot Jul 6 '12 at 15:25
    
Thanks for really detailed answer. I would like to see a list of small compatible HDMI displays, especially cheaper ones –  valentt Dec 31 '12 at 8:57
    
There aren't many cheap small HDMI displays. Up to this point, that size has been used predominantly for car computers and professional photographers/videographers. Check out Lilliput for most of your options, but keep an eye on ebay and other places. –  Zoot Dec 31 '12 at 15:30

I know this isn't exactly what you're looking for, but you might find this interesting.

You can purchase a lapdock, made for a cell phone, that will provide you a portable keyboard and monitor for use with your RPI. Simply connect an HDMI to HDMI micro female adapter to the lapdock.

They are often on sale for ~$60. Likely far cheaper than any other monitor you will find. and it's designed to be portable.

Here's a website that gives you a full rundown on how to accomplish this. http://rpidock.blogspot.com/2012/05/raspberry-pi-and-motorola-lapdock.html

Here is where you can purchase the cable needed for hdmi specifically. http://www.ebay.com/itm/280761232832?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_2827wt_1163

This is actually a really clever idea in general - it's certainly cheaper than similar devices built for rack cabinets, which is exactly what I'm going to use it for now. –  David Perry Jul 5 '12 at 17:57
    
@DavidPerry, yes, I've been thinking about buying one just in case I might need to do something like that. –  user606723 Jul 5 '12 at 18:29
    
This si a great answer, thank you. This makes Raspberry Pi great replacement for cheap home PC. –  valentt Jul 18 '12 at 9:55

If you there going for THE cheapest display, I think this would be it.

We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations. Answers that don't include explanations may be removed.

    
Thanks @euphorbium for an answer. Maybe you could expand it by including a description of the screen and why it might be cheap? –  Alex Chamberlain Jul 19 '12 at 9:39
    
This display comes with the caveat that it only has DC power hookups, so if you're looking for it to run on AC power, you'll have additional work to do. –  Zoot Jul 19 '12 at 15:34
