ASUS PQ321Q UltraHD Monitor Review: Living with a 31.5-inch 4K Desktop Display

Many consider me to be a 4K hater. The past few trade shows I’ve attended have been pushing it on consumers to replace their TVs, but I see less value in it. When it comes to a computer display, it is a different game. Unlike a 50” TV, we sit close to our monitors, even if they are 30” in size. We also have no worries about a lack of native content, since everything is rendered on the fly and native. There are no issues with the lack of HDMI 2.0, as DisplayPort 1.2 can drive a 3840×2160 screen at 60 Hz.

When it comes to 4K on the desktop, my main question is: how much difference will I see? ASUS is one of the first with a HiDPI display in the PQ321Q. While not truly 4K, it is a 3840×2160 LCD display that can accept an Ultra High Definition (UHD) signal over HDMI and DisplayPort. It also clocks in at a wallet-stretching $3,500 right now. The question is, are we seeing the future with displays here, or are we seeing a niche product?

What does 4K/UHD/HiDPI bring to the desktop? We’ve seen it for a few years now in smartphones and tablets, making their smaller screens more usable for reading and general work. My initial thought is more desktop space, as that is what it has meant before. With a 32” monitor and a pixel density this high, running it without any DPI scaling leads to a desktop where reading text is a huge pain. Instead I believe most users will opt for DPI scaling so elements are larger and easier to read. Now you have something similar to the Retina screen on the iPhone: No more desktop space compared to a 2560×1440 monitor, but one that is razor sharp and easier to look at.

To get to this pixel density, ASUS has relied upon a panel from Sharp that uses IGZO technology. IGZO (Indium gallium zinc oxide) is a material that replaces amorphous silicon for the active layer of an LCD screen. The main benefit is higher electron mobility that allows for faster reacting, smaller pixels. We have seen non-IGZO panels in smartphones with higher pixel densities, but we don’t have any other current desktop LCDs that offer a higher pixel density than this ASUS display. IGZO also allows for a wide viewing angle.

Monoprice 27″ IPS-G Pro LED Monitor WQHD 2560×1440

Monoprice is among the more interesting companies you probably haven’t heard of. Started out of an apartment around a decade ago, the company initially sold everything at a single price, hence the name. That business model may have worked when the product line was mostly cables and connectors, but the company now offers a diverse array that includes monitors (more in a moment), home theatre screens, graphics tablets, headphones, apocket-size pico projector, an action cam, even electric guitars – and, yes, cables, connectors and accessories as well. It’s a lineup with no seeming rhyme or reason, other than quality products at bargain prices.

And that actually is the rhyme and reason behind Monoprice products. According to CEO Ajay Kumar, the company looks for categories where vastly overpriced products predominate. That gives Monoprice room to create and sell products at dramatically lower price points, while still maintaining strong profit margins.
“We are in the right place at the right time with our business model,” says Kumar, who joined the company in July 2011. “We offer the same cable or accessory as national retail brands, but for much less cost. However, we are not cutting corners as we employ high-quality manufacturing partners who work with our specs. Our markup is much lower and we pass those savings to our customers. Monoprice brings them a value proposition they can’t find anywhere else.”
And that leads us to the Monoprice 27″ IPS-G Pro LED Monitor WQHD 2560×1440 Product ID 10489, which is what you came here for. I’ve been rocking this 16:9 (widescreen) monitor for over a month now and it’s stunning. Let’s take a look at the stats and find out why.
Start with the size, 27″. You don’t have to join Grindr to know that size matters. A larger screen means that you can work easily with more windows at once. It makes copying files and editing text and spreadsheets easier and obviously makes working with pictures and video more convenient, if that’s your thing. And if you’re a gamer, a large screen is essential. Ditto if you are, for instance, a daytrader or a designer.
Hand in glove with size is resolution. “WQHD” may sound like a Minneapolis TV station, but it means 2560 x 1440 pixels. Some 27″ screens max out at regular Full HD, which is 1920 x 1080. The higher resolution of the Monoprice unit means that more detail is visible, if your PC’s graphics card supports it. If not, you’ll be limited to 1920 x 1080 (or less, if your PC is really old). A large screen with high resolution allows you to display more information. It makes it easier to do more with your PC.
Since we’re talking graphics cards, another nice feature of the Monoprice 10489 is that it supports four different types of interface: HDMI 1.4, DVI, VGA and DisplayPort 1.2. That means that the monitor is bound to work with your existing graphics card. The package includes VGA and DVI-D cables, but these are standard length (around 6′). Because of the size of the monitor, it’s much easier to use longer cables – you can plug in the cable before maneuvering the monitor into place on your desk. Monoprice has you covered with available 15′ HDMI, DVI-D, VGA and DisplayPort 1.2 cables. Choose the one you need.
The monitor uses LEDs for the backlighting, rather than cold cathode fluorescent tubes. The benefit: more even illumination. And it uses In Plane Switching (IPS) display technology, which means you get a wide viewing angle with no color shift even when the screen is viewed at an extreme angle. Viewing angle is stated as 178 degree in both the horizontal and vertical planes.
Covering that screen is a glossy glass laminate with an antiglare coating. The antiglare coating is not a matte finish; the screen is glossy, but the antiglare coating reduces the intensity of any glare from reflected light. As with any monitor, you’ll want to position it so that ambient light is not reflected directly back at you. I’ve found the screen easy to use.
The monitor comes with a removable stand and has a 100×100 VESA mounting size for use with desk or wall mounts. The stand (which is completely removable) has rotate and tilt adjustments. It doesn’t have height adjustment, a feature found on a small number of other monitors.
The bezel is black plastic and is relatively thick. The OSD controls (brightness, etc.) are easy to reach. The connectors are in the usual awkward place for monitors, along the bottom bezel.
Several other stats are key. One is dead pixels. The monitor has over 10 million subpixels (2560 x 1440 pixels x 3 colors per pixel). If any one of those subpixels is stuck in the on or off position, you get a dead pixel – a spot that is always dark, or always white, red, reddish, green, greenish, etc. Unfortunately, dead pixels are a potential fact of life on all monitors – but Monoprice tells me they offer a zero dead pixel guarantee for a year. It’s an unusually strong guarantee, since other manufacturers often will only guarantee that the dead pixel count won’t exceed 5 or 10. The unit I received had no dead pixels.
Also important are brightness and contrast. Monoprice advertises a brightness rating of 440 cd/m², which it says is more than 15% brighter than most comparable displays, and a maximum dynamic contrast ratio of 80,000:1.
The display is indeed bright, but this is the one area where I noted a difficulty with this product – the screen is a bit too bright, even with the brightness adjustment turned down to the lowest setting. As a result, black areas on screen are rendered slightly grayish. For most people and most applications, this won’t be a problem – and it’s a phenomenon that’s scarcely unique to the Monoprice unit – but graphic designers will want to carefully compare this screen with others to see what meets their needs.
The panel features 109 pixels per inch, which translates to a 0.2331mm pixel size. The unit also includes builtin stereo speakers, which can be fed via a stereo audio cable, as well as audio from the HDMI connection. As with most builtin monitor speakers, the sound was tinny and unimpressive, so I don’t recommend using them. Buy a pair of standalone computer speakers instead.
Another stat is response time, which the company says is 6 milliseconds (gray-to-gray response time). That’s a measurement of how long it takes the monitor to change the image when the PC tells it to, and is an issue for almost no one except gamers.
Bottom line: if you’re looking for a high-quality 27″ WQHD IPS LED monitor at a great price, pick up the Monoprice 10489.

Variabel di Shell Script

In the previous issue we’ve become acquainted with a shell script and managed to create a very simple shell script. If we look, we did not perform any processing on the shell script. We only show a message on the screen and execute commands on the shell through shell script. What if we want to make the program more interactive shell script?

As with any programming language, shell script also serves to recognize the variables that can hold information temporarily for a variety of purposes, for example to compute or determine the output results. You may make as much as possible or use a variable in your shell script. Name the variables are independent, large and small letters should, but make it easier to remember, make it a habit to create standard rules in the manufacture of the variable name. At this writing, all variables will be written in lowercase.

Variables can be divided into two types, namely environment variables and user variables. Environment variables are variables that have been previously determined as a part of the shell used (bash). By default, the name of this variable using all capital letters. Example of this is the $ USER variable that will contain the user name you are currently using, $ HOME home directory which contains the address of the user that is used, and so forth. To display the entire value of an existing environment variable, you can use the set command in the terminal (Figure 1). User variable is the variable name specified by the user themselves and not by the shell used.

Variables can be accessed by using the dollar sign ($) before the variable name, for example, we have a variable named “my name”, to access the value stored in the variable, we use the $ my name. To give value to a variable, we use the sign “=” is immediately followed by the value we give without any spaces, for example my name = Willy. What if the value that we want to give is a sentence? Use double quotes as the opening and closing value of a variable, such as my name = “Willy Sudiarto Raharjo”. For example, see listing 1 and try running on your computer. Seen that the value of the variable Sudiarto be regarded as a command and not part of the variable because it is not enclosed in double quotation marks. Please be careful in giving a value to a variable.

You can combine environment variables and user variables in a shell script is the same, as in listing 2. What if want to write a message using the $ character, such as “It cost me $ 15”? If we are not careful, it could be a shell script would be wrong to interpret the information that we provide and try to take the value of variable 1 (which will not contain any) and display it as a “price 5”. To fix this, use the escape character to indicate that the next character will be recognized as a regular character and not as a substitute for a variable, which marks the backslash “\” as in listing 3.

One character that needs more attention is the backtick character “` “(position number 1 on the left side your keyboard) because this character has a special function in shell programming, which is able to accommodate the output of a shell command in a variable. As an example, we will hold the result of the date command into a variable date and display its contents using the echo command as in listing 4.

To be able to receive input from the user and store it into a variable, we can use the read function is followed by the name of the variable that we want to use to store the values ​​as in Example 5 listings.

Mozilla ponders blinkers for your browser

Mozilla Labs has outlined an experiment it’s conducting in improving the personalisation web publishers can offer readers who browse their sites using Firefox.

The outfit says it’s been working on the idea since last year, when it “conducted a series of experiments in which a user’s browsing history could be matched with interests in categories like technology, sports and cooking.”

In return for opting in to the trial, lab rats were offered “insight into how they spend time online.”

Mozilla Labs is now wondering “what if these interests were also available for the user to share with the websites they visit to get a better, more personalized browsing experience” so that “content creators and consumers could benefit from Web-based interests”?

Here’s one scenario the outfit has imagined as resulting from this line of thinking:

“For example, let’s say Firefox recognizes within the browser client, without any browsing history leaving my computer, that I’m interested in gadgets, comedy films, hockey and cooking. As I browse around the Web, I could choose when to share those interests with specific websites for a personalized experience. Those websites could then prioritize articles on the latest gadgets and make hockey scores more visible.”

Some publishers have already pressed the API for this kind of thing into service, according to the Mozilla Blog, but the code is not in the wild and is being tested – technically and conceptually – as Mozilla figures out how people will react to websites that dynamically change content based on readers’ past behaviours.

One example of successful personalisation mentioned in the posts announcing the initiative is The Guardian’s offer to ensure its readers see no news about the birth of George Alexander Louis Windsor. That’s a service many will doubtless enjoy. Whether such personalisation can result in readers choosing only to encounter lines of inquiry and opinions they already agree with, and therefore deciding to consume media that re-enforces their feelings rather than offering broader perspectives, is a wider debate for another day. Or the comments.

Pre-Order Asus 31.5″ 4K IGZO Monitor for $3500

Asus is reportedly now taking pre-orders for its 31.5 inch monitor (PQ321Q) featuring Sharp’s anti-glare LED-backlit IGZO technology. It sports a screen resolution of 3840 x 2160, 140 pixels per inch, and not only cuts down on energy consumption but features an extremely long durability given that Sharp’s tech doesn’t constantly refresh the images. It’s all static until something moves on-screen.

The company introduced the new monitor last month, reporting that Sharp’s IGZO tech supports smaller transistors than amorphous silicon thanks to significantly higher electron mobility. It also not only reduces energy consumption, but reduces the monitor’s overall bulk as well: at 35 mm at its thickest point, the PQ321 is the thinnest 4K UHD monitor available today, the company said.

A Sharp rep said during CES 2013 in January that the 31.5 inch panel will be marketed to professionals first given the end-price. The prototype also had ten-point touch input which apparently didn’t make it into the company’s own PN-K321 31.5 inch IGZO monitor selling for $5,000 USD. The Asus model also doesn’t support touch.

The upcoming PQ321Q supports wide 176° horizontal and vertical viewing angles, 10 bit RGB “deep” color, and an 8 millisecond gray-to-gray response time. Other features include a 0.182 mm pixel pitch, a max brightness of 350 cd/m2, a max contrast ratio of 800:1, picture-by-picture support and HDCP support. The monitor’s typical power consumption is 93 watts.

On the connectivity front, the I/O panel has two HDMI ports, a DisplayPort, and an RS-232C port for old-school VGA connections. There’s also a 3.5 mm mini-jack for PC audio input, a 3.5 mm mini-jack for AV audio input, and a 3.5 mm mini-jack for earphones (for HDMI and DisplayPort).

Last month the company said that the new display is the “equivalent to four Full HD displays stacked side-by-side.” It can now be pre-ordered on Amazon here, and on Newegg here, both requesting $3,499.99 USD. The monitor is slated to arrive on July 16, 2013.
