12 ways Windows 8 dominates the OS competition

While we’re on the topic of hardware, let’s talk monitors. More specifically, let’s talk lots of monitors.

Display die-hards love Windows 8’s deeply improved multi-monitor functionality—it’s a huge step up over Windows 7’s several-screen support. Is it perfect? Nope. But it’s pretty darned good, and an absolute cinch to set up.

Macs and Linux boxes have dead-simple multi-monitor software, too, but they can be a hassle to set up on the hardware side. Mac desktops drive video via
Mini DisplayPort or Thunderbolt connectors. Both technologies are utterly awesome, don’t get me wrong—but neither is anywhere near as
ubiquitous as HDMI, DVI, or VGA. Linux multiple-monitor support works great, except for when it doesn’t. Finding working monitor drivers can occasionally be a hassle, and Linux sometimes stutters while trying to drive multi-monitor setups in multi-GPU rigs.

How DisplayPort multi-streaming delivers new levels of multi-monitor madness

When a vendor sends us a demo system, it typically take great care to ensure that we experience the system exactly as the maker intends us to. So when VESA, the trade group responsible for the DisplayPort standard, said that it was sending PCWorld a multiple-monitor demo system similar to the one it exhibited at CES in January, I expected it to arrive bundled with a detailed guide and all the software needed to present DisplayPort in its best light.

Imagine my surprise when an MSI GX60 gaming laptop, two 24-inch Dell U2413 displays, and a 21.5-inch HP Elite L2201x showed up in the PCWorld Labs without so much as a user manual for any of the four devices. “Wow,” I thought. “They must be pretty confident that setting all this up will be self-evident.”

Robert Cardin
The Mini DisplayPort connector is located on the MSI GX60’s rear panel, between the VGA and HDMI ports.

As things turned out, setup was pretty much self-evident. The GX60 has HDMI and VGA video outputs, but obviously I was more interested in its Mini DisplayPort. Both of the Dell monitors have full complements of digital video inputs (HDMI, DVI, and full-size DisplayPort, along with ports labeled ‘DisplayPort In’ and ‘DisplayPort Out’), but the HP display has only a DisplayPort input.

I connected the full-size DisplayPort on the first Dell to the notebook, plugged a second cable to that monitor’s DisplayPort Out, and connected that to the other Dell’s DisplayPort In. Then I attached a third cable to the second Dell’s DisplayPort Out and plugged it into the HP display to complete the chain.

Taking stuff apart

Last Saturday, I took apart an old and broken laptop of mine: a Sony Vaio VGN-TZ31XN. That was once a top of the line executive laptop. I bought it in 2009 when the model had just been discontinued and superseded by a new one, so it wasn’t too expensive.

The laptop had an 11″ 1366×768 screen, a 1.2 ghz Core2duo, 2GB of ram and 120 GB hard drive. The reason I paid 1000 Euro for such lowly specs is that it had a weight of 1.25 kg, doing about 6 hours on a battery charge.

Impressive piece of tech

I’ve been wanting a new laptop since I started to bump into performance issues during 2011. 2 GB of ram is not sufficient in a time of HTML5 – there are web pages which eat several hundreds mbs of ram. And unfortunately the Linux desktop isn’t getting lighter either (it’s part of why I decided to help Will and Klaas with Klyde for hackweek). And I’ve been doing some light video editing lately as well as more image editing. So when the screen of my laptop finally gave beginning of last year, I simply ordered my new Samsung Series 9. That Series 9 was actually more expensive than the Sony (prices have gone down since then). It is a step forward, but it is sad that it took the IT world over 5 years to finally eclipse what Sony did in 2007. And not even on every level – my Sony included a DVD burner, 3-antenna wifi, TWO card readers, mini-PCI-express, 120 GB spinning rust, FULL ethernet and VGA ports, Firewire and a removable battery in barely 100 gram more!

Opening up

When you open up the Sony, it becomes apparent how they managed to cram so much functionality (essentially everything a ‘normal’ laptop offers) in such a thin enclosure: they must have worked with the assumption of an unlimited budget. Seriously, it is clear why this laptop was over 2K: the target user group seemed to be entirely unwilling to compromise on features. This thing is far more complicated inside than modern ultrabooks. My Samsung S9 is mostly battery inside: it has a single, laptop-wide motherboard with 2 boards (wifi and mSATA) attached to it.

Nothing compared to the Sony: taking it apart reveals a square motherboard, a battery-power related board inside a casing, wifi board (the usual), blue-tooth board (tiny), audio board (2 chips & capacitors, audio in/out, 2 speakers, microphone all attached), 2xUSB+card reader board, touchpad board (the touchpad itself also has logic, of course), quick function keys board, 2 more small board I can’t identify. Then the DVD burner has its own internal boards (2) and one on the outside, apparently to interface between the mobo and the dvd burner. Oh, and of course, memory is separate and can be replaced. The webcam also has its own 4 cm long/half wide/double sided board.

Crazy, huh? All that is connected via a

dual monitors possible (2)?

By sgull

In reference to my previously started thread http://www.doityourself.com/forum/co…-possible.html which maybe tended to drift away from addressing my issue somewhat, I’d just like to ask again about the possibility and/or method by which I might be able to hook up my TV and desktop pc via VGA video cable and have my TV screen display the identical video display of my desktop monitor but without having a dual-output (or “dual-head”) video card in my desktop pc. Without a dual-head video card, is my only other option to get an adapter such as this?: Matrox DUALHEAD2GO D2G A2A If | eBay
And if I did obtain such an adapter, is it likely to significantly degrade the video output quality of the connected monitors? Any comments appreciated. thanks.

Lenovo IdeaCentre Q190 review: Call it a full-figured micro PC

Compared with Intel’s diminutive NUC and Sapphire’s slim and sexy Edge VS8, you might think of Lenovo’s IdeaCentre Q190 as a full-figured micro PC. It’s not the smallest such model, but it boasts a ton of ports, it has enough interior space to move air over its components, and it has a Blu-ray drive option. If you’re looking for a home-theater PC, those are important features.

Design and ports

The Q190 is a small monolith measuring 6.10 by 7.55 inches. It’s 0.86 inch thick (expanding to 1.5 inches thick with its piggyback slot-feed optical drive attached). A stand that stabilizes the unit when upright adds about another half-inch of height, but Lenovo also provides a VESA mounting bracket so you can mount the Q190 on the back of a display.

Robert Cardin
A drop-down panel (lowered here) hides the Q190’s front ports.

Mic and headphone jacks, two USB 3.0 ports, and a six-in-one media-card reader are hidden behind a door on the front of the unit. On the back you’ll find HDMI and VGA video outputs, three USB 2.0 ports, ethernet, an optical S/PDIF port, and the power jack for the AC adapter. The computer and the optical drive both have Kensington lock points. The Q190 also has a built-in 802.11b/g/n wireless network adapter. The bundled keyboard and mouse are middle-of-the-road units, but Lenovo’s palm-sized Enhanced Multimedia Remote, which combines a backlit QWERTY keyboard and fingertip mouse and costs $80, is worth a look if you plan to use the system from your sofa.

The Q190 is not quite as quiet as the nearly noiseless NUC, or the Edge with its super-quiet fan, but we didn’t find its noise signature to be bothersome.

Samsung Chromebook 3: Cheaper, more productive alternative to a tablet

Samsung’s latest Chromebook – the Series 3 XE303C12-A01US – is small, slim, and speedy. This little laptop weighs less than 2.5 pounds and packs a decent performance punch, assuming you’re comparing it to the right machines.

A laptop-shaped improvement to a tablet or smartphone

Google
The Samsung Series 3 runs the browser-based Chrome operating system.

The Samsung Series 3 looks like a laptop, but it’s not. It’s equipped with a mobile processor and very little internal storage, and it runs the browser-based Chrome operating system instead of the Apple Mac OS X or Microsoft Windows platform. It performs more like a tablet or advanced smartphone than an ultraportable. If you’re looking to do much more than surf the web and create cloud-based content (via Google or another service), then this is not the laptop for you. But if you’re looking for a tablet with much better content-creation functionality–namely, an integrated keyboard–then the Samsung Chromebook is an appealing option.

Our review model, which costs $249.99 as configured, sports a 1.7GHz Samsung Exynos 5 dual-core ARM processor, which is the same mobile system-on-a-chip found in the Google Nexus 10 tablet. Like the Nexus 10, the Chromebook pairs the Exynos 5 with 2GB of memory and 16GB of hard drive space.

The Chromebook also sports built-in Wi-Fi 802.11 a/b/g/n, two USB ports (one USB 3.0, one USB 2.0), a 3-in-1 card reader, and a headphone/microphone combination port. There’s also an HDMI-out port on the back of the machine. Samsung offers USB dongles for VGA-out and Ethernet (sold separately).

Screen Resolution on External Monitor from RHEL 6.3

By rchaud10

Hey everyone,

I have a KVM or External monitor (19″ Dell) that I am trying to hook up to a laptop running RHEL 6.3 (via VGA which is the only option). When I connect it, and go to System->Preferences->Display, the max resolution option it provides me for these external devices is 1280×1024. Now, the KVM should provide a maximum resolution capability of 1600×1200, and the Dell monitor should have a capability of 1920×1080. Neither of those come up. How do I get this to work? I was reading online that Red Hat OS needs to be configured for the graphics card on the laptop in order to provide higher resolutions. I would hope it’s simpler to this. Any hints or tips?

Redirecting console output to ILOM during installation

By u_paludan

Hi,
I need to install solaris remotely via the ILOM port on a x4170 box, and I have downloaded the Solaris 11 for x86 – text install image and burned it on a DVD.
When I boot the box, it’s showing the boot_archive loading percentage on the SP console, but when it’s done and start the interactive install menu, it’s not displayed on the SP console, only on the VGA screen.

In solaris I would solve this by using the eeprom console command, but I don’t know how to set the redirection during installation.
Do I need to somehow set it up in the BIOS?

Any help is much appreciated

The Day My Mac Died

By Tim Beyers, The Motley Fool

Filed under:

I’d been having trouble with my nearly three-year-old MacBook Pro since the holidays. Last week, the problem elevated from occasional to frequent as my writing days were suddenly overrun with forced restarts called “kernel panics.”

A visit to my local Apple Store confirmed my fears: I’d need to leave the machine for repair, with the likely fix either a new hard drive, new logic board, or both. A two-year-old Chromebook, given to me at Google‘s early 2011 developer conference, would become my primary tool for getting work done.

Two reasonably productive days later, I think it’s fair to say the Chromebook is a useful machine but a lousy Mac substitute.

3 reasons the Mac still rules
This isn’t the new Pixel we’re talking about. Rather, I use an original Samsung 500 series Chromebook with just 2GB of memory and 16GB of storage. A lightweight machine in every sense of the phrase, you might say. Comparing it with my full-fledged MacBook Pro was always going to be unfair.

Thing is, I didn’t start the comparisons: Google did when it introduced the Pixel and priced it as if it were a Mac substitute. Unfortunately, its dual-core 1.8 GHz processor clocks in much slower than newer Macs. Even my old Pro and its single-core 2.66 GHz processor hold up well thanks to 8GB of RAM, important when you’re working with lots of open tabs connected to cloud-hosted software.

Now imagine how the Series 500 might perform under the same conditions, and you’ll get a sense of what my days were like. Every task took longer. Writing. Research. Just the act of switching between tabs forced the built-in Chrome OS to reload pages made idle in order to save on spare memory.

I’d need a USB adapter before plugging into the wired Ethernet network, only to find it faster to stick with Wi-Fi. And finally, try as I might, I’d fail at connecting my Chromebook to an external monitor. Samsung built a custom VGA adapter port into the Series 500 that a service rep I spoke with said was obtainable only via mail order.

So what’s the good news, sparky?
For all the 500’s drawbacks, it’s important to note that I still got a lot of work done. Support for USB peripherals such as my external mouse and keyboard made writing easier, while the Chromebook’s built-in Wi-Fi radio consumed bandwidth almost as fast as I needed.

As an investor, I draw three lessons from all this:

  1. The Chromebook is a decent alternative but not a substitute. Bring me a machine that’s so loaded with memory and CPU power that there’s never a need to idle a page. Performance matters on the Web, and constant loading and reloading make the Chromebook less a workhorse and more a luxury machine. Alter the equation, Google, and profits will follow.
  2. Google Drive and Dropbox are disrupting storage. Computer makers are displacing high-capacity magnetic hard drives in favor of power-friendly …read more

Dell OptiPlex 9010 business desktop PC review: small but powerful

The small form factor Dell Optiplex 9010 Desktop takes up little space, packs a nice performance punch, and is very easy to repair or upgrade. If also has all the service and warranty options and legacy connectivity businesses need. Couple that with Dell’s promise of a long product lifespan and plenty of warning for upcoming changes, and you have a powerful compact PC that won’t stress out your purchasing agent or IT personnel.

Design

Dell refers to the small form factor 9010 as a Desktop, which it is in the older sense of the word–a PC that literally sits on top of your desk. At only 12 inches deep, by 11 inches tall, by 5 inches thick it will fit easily beside a monitor, or flipped on its side, serve as a monitor stand. Styled in black and gray, it also looks like it belongs on your desk. Being small also makes it easy to hide away, if that’s your preference.

Input Ergonomics, Connectivity

Our small form factor 9010 Desktop shipped without a display, though there are a number of 20-inch or 24-inch LCDs ($250 to $400) as well as dual-display options available. We did get a mouse and keyboard, which, while obviously not top-tier items, get the job done. The mouse tracks well and the keyboard, despite being very light in weight, has a better than average typing feel.

The 9010 Desktop small form factor offers a large array and logical mix of modern and legacy ports. There are a whopping 10 USB ports; four on the front of the unit, six on the back, and two in each set are USB 3.0. There are also dual DisplayPort connectors, VGA output, a gigabit Ethernet port, and a serial port. That latter is to support the still rather large fleets of serial port devices such as hand scanners still used by businesses.

Lenovo gives Chrome OS a try with Chromebook for Schools

In perhaps a sign that Chrome OS hasn’t been a failure, Lenovo plans to release its first Chromebook laptop, which it calls a “rugged” model for K-12 schools.

Before now, only Acer and Samsung have offered computers based on Google’s Web-based operating system. Their first Chromebooks launched in 2011, and both companies released new models late last year, including a $200 laptop from Acer and a $250 laptop from Samsung.

Lenovo’s ThinkPad X131e Chromebook

Lenovo’s newly unveiled ThinkPad X131e Chromebook runs on an Intel processor (no word on which one) and has an 11.6-inch, 1366-by-768 resolution LED display. It also has three USB ports, HDMI output and VGA output. A blog post from Google says the X131e lasts 6.5 hours on a charge, and it weighs about four pounds. A bumper for the top cover, stronger corners, and reinforced hinges account for the laptop’s rugged design.
