Ask Slashdot: Portable High-Resolution External Displays? 141

First time accepted submitter paragonc writes "I am a software engineer who works remotely. I'm amazingly lucky to live in Austin, Texas where I have access to multiple high quality co-working facilities within biking distance. While these places are great for networking and establishing a rhythm to daily life, not having a permanent desk forces me to pack my gear in and out each day. This means i pack light. My current Go Bag includes a 13.3 inch MacBook pro, and an iPad running avatron Air Display. This has worked well, but i'm sorely missing having a real high resolution external monitor. I've looked at a few of the USB powered external displays, but the resolution seems to only hit 1366 X 768. I'd be curious if slashdotters have any tricks up their sleeves on how to implement a high resolution portable external displays."

    WTF is a 'real high resolution' monitor for you and what do you consider 'portable'.
    Your Mac and iPad are already pretty good, so what are you actually looking for?
    There are USB2HDMI adapters that work up to 1080p so this must not be enough for you.

    • The thing is... he is not looking for an USB powered adapter, but actually for an entire USB powered display.

      As he seems to be looking for a replacement of his iPad as an external monitor, I suspect that he is looking at something like 1080p and somewhat larger, maybe the size of his macbook pro.

      The only thing that comes to mind for me is the old, ridiculous ThinkPad W700ds with the built-in second screen.

      WTF is a 'real high resolution' monitor for you and what do you consider 'portable'.

      While he should have been more explicit, it is obvious that what he wants is more vertical lines of text on screen and more characters per line. High resolution displays like retina screens are great for images and crisper text, but they don't actually help fit more text on a screen. The new MacBook Pro Retina may have 2880 x 1800 resolution, but for software enginers it isn't much better than a 1440x900 screen because it doesn't fit more text (at a readable size) than this smaller resolution.

      For someone like myself who is used to working on either two 27" 2560 x 1440 monitors at work or a 30" 2560x1600 + 24" 1920x1200 monitor at home, the removal of the macbook pro 17" laptop left a big hole in the marketplace for 'high text density' laptops. If someons starts making a 1920x1200 laptop again along with a 1200 vertical resolution portable external monitor, they would have my business.

      Since I won't need a new laptop for a couple years, I am really hoping that a 17" Retina display laptop comes out by 2015. That would be essentially the same thing as the old 17" macbook.

      • The new MacBook Pro Retina may have 2880 x 1800 resolution, but for software enginers it isn't much better than a 1440x900 screen because it doesn't fit more text (at a readable size) than this smaller resolution.

        I disagree. The rMBP runs very nicely in "more space" mode, which is the equivalent of 1920x1200 mode. It's quite usable for smaller and still readable text.

        • Still readable text is wholly subjective. And I'm still holding on to this 2008 17" MBP until I can buy a 17" replacement.

        • Sorry disagree with you. I use a Macbook Pro 14", but have a REALLY old Dell Inspiron 6000 (10 years old now), with native 1920x1200 res. Yes Dell had such a beast back then. It was only for a year or so and I bought it right away. Even though the CPU is woefully underpowered I use it as thin client for my Server VM's and have to say it is awesome working on such a screen. You really have quite a bit of real estate to code, debug, etc... So yes Apple should bring out another 17" notebook.

      • And you just hit the big issue of portability: it's not resolution as much as overall size of the screen that's the most important factor.

        So what the original poster is looking for is a huge screen that is somehow still portable... and until we have foldable/rollable screens, that's always going to be a trade-off.

      • The Retina MBPs can be run scaled (1680x1050 for the 13"er and 1920x1200 for the 15"er), or in their native resolutions (using third party software). If you like OSX and Apple, they're pretty awesome for high-res coding and so on.

        For the OP, I'd recommend simply replacing his MBP with an rMBP, or at least a device with a 1080p display (available anywhere from 12" [Zenbook] to 17")... since external high-res displays aren't to be had, a decent internal display is the next best thing.

      • the removal of the macbook pro 17" laptop left a big hole in the marketplace for 'high text density' laptops.

        There are plenty of 17" HD laptops around, just not from Apple. That's what you get if you tie yourself to a single vendor for your software and hardware.

          The Macbook Pro 17" was the only one with 1920x1200 resolution. There are now no vendors that sell that level of resolution or higher on a screen big enough for the equivalent of 1920x1200 to be very readable.

          • You're saying that 17" 1920x1200 is good enough but 18.5" 1920x1080 is not? Sorry, that's silly.

              Why is that silly? 1920x1200 has 200 extra vertical pixels, meaning quite a bit more vertical room for text. Considering most development environments probably lose around 300-400 pixels to toolbars, debug windows, etc., that is around a 15% increase in vertical screen size for your actual code.

              I agree that a 18.5" 1920x1080 screen is very readable but it loses significant screen real estate that some laptop owners have enjoyed for over 10 years.

              • 1920x1200 has 200 extra vertical pixels, meaning quite a bit more vertical room for text

                No, it has 120 extra vertical pixels, i.e. 10% more. But that's irrelevant, since HD resolutions on laptops are high enough that you simply choose a 10% lower DPI and your text is going to look fine. On an 18.5" diagonal laptop with 1920x1080 resolution, you are going to have more room, not less, than on a 17" 16:10 display, even if your DPI are a little lower.

            Which is interesting because Apple was the LAST vendor to offer a 1920x1200 17" display in a laptop. Every PC vendor did that until the price fell out. Apple had to be dragged kicking and screaming into the >100 dpi club. Now they pretend to have invented it.

            And, of course, there are 1920 displays available, it's just that 16x10 is regrettably gone.

    I keep the monitors in two oversized suite cases. The trick is to get foam padding that fits the suite case and the monitors.
    I found a place that cuts the form. I went with my suite case and monitor and they cut everything just right.
    The form cost me about $200. The suite case is about $300 (each).
    I've been all of the world with the monitors. My only issue is that international airlines only allow one bag
    and the cost of check a heavy second bag can be equal to the cost of flying business class. So my solution
    is to fly business class.

    I don't think you would be so crazy to travel with a 27" monitor but the short answer is you should get custom form made so you can travel with any monitor you like.

      That is pretty awesome. Can you provide the names of the suit case you bought that is big enough for this, along with the type of foam you bought? I don't travel very much for work, but if you have found a reasonable way for me to transport my two apply thunderbolt displays I would be very interested in knowing the details. It would be useful even for times where I have to move my monitor setup to another area of the office to work with another team temporarily.

      Your math does not add up. A ticket Paris-NYC is roughly USD 700. The business class ticket is roughly USD 2200. The case solution you mention costs about USD 800, the monitors are USD 1000 each.So for the surplus of business class alone, you can buy a brand new cinema display every flight. Looks like you take the least economic option possible. But since you travel around the world first class carrying two cinema displays in tailored cases, you must be loaded. Right.

      • You could also buy a storage locker at the far end and leave the monitors there (assuming you don't have an apartment or office you could leave them at)... if you travel often enough, it'll be more economical that way. You aren't factoring in the cost of extra oversize baggage.

      For the cost of the difference between business class and economy on most international flights you could outright purchase 2 27" monitors when you go there. Plus, if your presence is sufficiently valuable to be worth a business class flight then your employer should be more than happy to provide you with the screens. The only possible exception I can think of is if you need color calibrated displays, in which case you'd be better off carrying a 1kg calibrator instead.

    I'll take my guess at what the OP is asking. He refers to USB-powered displays, but complains that they are too low-res. They really are a great idea and I could see a bunch of uses for them.

    Here is a 16" USB-powered display [amzn.to], which combines a DisplayLink USB display adapter with a flat-panel LCD display. The problem is that its pixel resolution is only 1366 x 768, which is pretty low density for that panel size. It's like a typical entry-level 15.6" laptop panel. If you look at 15.6" laptops, they start at 1366x768, then as you move up the model range, the pixel res goes up to 1600x900, then further up, 1920x1080 is about as high as it goes at this size.

    I suspect that the OP would like a product just like this display, but with a 1600x900 or 1080P display panel like those used on higher-end laptops. This would totally make sense, but some quick searches didn't turn anything like this up on Amazon. So his real question is if anybody knows of one of these types of displays that has a higher-res panel. Personally, I'd consider one of these as well for on-site video editing.

    There is a similar 21" USB-powered display [amzn.to] which does run 1080P but it's up to the OP as to whether he still considers that portable or not.

      Maybe it's a bandwidth issue. At 480Mbit/s you can push 1366x768 24 bit colour at 20 Hz. There would possibly be some compression, but it can't be too fancy as you'd have to drive it from USB power (if you allow an external adapter then just use DVI or DisplayPort anyway). Now with USB3 there is 10x as much bandwidth and more power, but that only equates to a factor sqrt(10)~3 in linear resolution (i.e., bandwidth increases greatly with pixel density). Still, a factor 3 on 1366x768 is amazing resolution, so

      • by Collin ( 41088 )

        well, they do have a 1080P 21" version [amzn.to], so it's unlikely bandwidth is the gating issue. DisplayLink has been doing this for a while with USB video adapters. I am not exactly sure how they implemented the link protocol, but it likely isn't pushing raw pixel data since it needs special drivers. It likely sends API calls for the chip at the other end to execute and only sends raw pixels for bitmap areas like photos or videos.

    • I tweeted this [twitter.com] to @AOCusa, so maybe if enough people get on their case about it, they will make a 1080P version: "@AOCusa Please make your 16" USB Display with a higher-res panel (1600x900 or 1080P). Great idea, but 1366x768 too low to add much value."

    It looks like you now have a new company idea. Assuming the market for one of these is anything other than minuscule for whatever price point you are able to hit while building them in China or Japan, assuming you can drive something of that resolution from USB power in the first place. Personally, given the proce differential between "retina: and "non-retina" devices, all other things being equal, I think that these would be of limited use for everyone except professional video editors or the idle rich.

    If you are actually serious about needing the external display space for something other than field video editing, then you have picked the wrong coworking space, since plenty of them have pluggable displays available, and some of them even have cable vending machines, in case you are lacking the necessary cable to hook up to your laptop.

    For the Austin area, I know of at least Conjunctured is one company that has so-called "community monitors", but they are first come, first serve, so if you wanted one there, you'd need to get there pretty early to claim one before they were all spoken for already.

    It's 15", has a 1600x900 resolution, and does everything else perfectly. I doubt it would be hard to get one of those portable battery extenders to interface with it and make it untethered as well as portable. Something like this, perhaps? http://www.amazon.com/gp/product/B005NGLTZQ [amazon.com]
  • Aren't there all kinds of cheap 1080p projectors on the market? I got one from Costco a few years ago for about $900. Use it to play Xbox mostly, but somehow it's still working on the original bulb, and is still plenty bright when projecting onto a 9 foot wide screen.

    A projector is often smaller than a monitor, and your screen size is only limited by your available wall dimensions.

      900$ is cheap for 1080? you are a special kind of stupid

      • Well, he is projecting a 9 foot wide screen. Even assuming that's diagonal, that's the equivalent of a 108 inch display. If you wanted an LCD panel that size, you'd be paying thousands, if they even exist. I think the largest consumer LCD I've seen is around 80 inches. So $900 for a 108 inch display isn't that bad at all.
  • Get an inexpensive LCD screen (about $140 at Newegg), I have a slightly older version of this Asus 21" 1920 x 1080 LCD back-light monitor, works great and is fairly light weight:

    Make a case with some foam padding and cloth that won't scratch the screen. Maybe something like a Pelican case (the monitor above is about 15" x 20").

    Looks like there is a Hackerspace in Austin. Go visit them and maybe they will be able to help you hack something togeth

  • I just saw this article: http://blog.laptopmag.com/asus-mb168b-portable-monitor [laptopmag.com] Looks like ASUS is coming out with a 2lb 15.6" 1080p monitor for ~$200. Comes with case that converts to stand, and monitor can be driven by a single USB 3.0 connection. Looks like a steal.

For God's sake, stop researching for a while and begin to think!
