LED Monitor Review: LG FLATRON E2041

My Old AOC CRT Monitor began to show signs of dying. It would occasionally black out for a few seconds. Sometimes lightning streaks  would run across the screen.

I bought that monitor way back in 2006. It served me well for 5 years. It was very durable and AOC is a good brand.

And so I had no choice but to buy myself a new monitor. I would have preferred another CRT Monitor but they were no longer available. Even the more recent LCD screens are being phased out in favor a the newer LED monitors.


(This was not my first choice but it was the next best thing available in the computer store I visited).

1600 X 900 Resolution (16:9 Aspect Ratio)
Contrast Ratio: 5,000,000:1
Brightness: 250 Cd/m2
Dimensions W/Stand (WHD): 17.44" X 13.78" X 6.54"

My Feedback

This monitor comes with two connectors VGA and DVI.

It comes with a CD that is supposed to contain the manual and monitor drivers. However, when you install the monitor driver contained in the CD it will always give you an "Installation Aborted" error.

An Amazon customer wrote about this problem. But don't worry. The monitor is plug and play. It works fine with the default Windows 7 driver.

Content of the CD

What you will actually find in the CD are PDF manuals. But I did not find them helpful. Explanation on the various features and functions of the monitor are very sparse.

And the CD also contains a color calibration file, E2041 ICC Profile. But I also ended up using the default Windows 7 calibration because the one given by LG was too dark.  You could not distinguish the lighter shadows from the dark shadows.

The CD also contained the monitor driver setup information. It is a text file. If you are an expert in Windows Registry editing, perhaps you can enter it manually. Otherwise, don't touch it. You will do fine without it.

Monitor Control Panel

The Monitor Control Panel is found at the right lower side of your monitor. They have no label. You will have to refer on the display on your screen when you are using them (this had me confused at first).

Overall Experience

It is a pretty good monitor. LED is really better than LCD. Picture quality does not change even if  I view it at different angles or when I am far from the screen.

I would still say that CRT monitors produce crisper images but LED monitors are one step closer compared to LCDs.

Privacy and Your Digital Identity

If someone had access to everything you have posted all over the internet they will know who you really are - perhaps even more than many of your close friends.

Imagine me as this person. I know who your elementary, highschool, and college classmates. I know who your former and current officemates are. I know your preferences and your interest based on the websites you visit.

I know your hobbies based on the photos that you shared and the organizations and clubs that you've joined. I know your favorite hangouts based on the statuses that you posted.

I know your Social Security Number, your Bank account, and your Credit Card information – every data about you.

I could use this information for something harmless as giving them to commercial companies so they could send you offers that you will probably like because they are based on your personal data.

Or this data could get leaked to individuals who have more malicious intention.

What are the bad ways your personal data can be used against you?

1. Stalking
2. Criminal Intent (Kidnapping, Theft, Robbery, Murder, etc.)
3. Slander / Mud Slinging / Destroying your Reputation

You would probably say I am just paranoid.

Just the past week we've heard that someone hacked into Sony's Playstation Network and into the members personal details. It is not stated whether credit card information were leaked but it is not far fetched.

And then Facebook admitted that they have been leaking personal data to third parties for years. And only because it was revealed by Symantec, the security company.

Facebook also admitted to hiring a PR company to run a negative campaign against Google. If a company would stoop so low as hire a company to do something unethical, could you ever trust them with your personal information?

Apple is also being sued because of the Ipad and Iphones location tracking because they store the information in their databases and it can be restored using itunes. The main concern was, what if someone hacked into these databases?

Lately, I have been weary with this Internet companies since they seem to bent on using their customers' data to every profitable way they can imagine. And hackers have become bolder and more sophisticated in their methods. So right now I am being more careful with the information I share. For starters I think there will be no more personal social network accounts for me. They actually do more harm to me than good.

Again am I being overly paranoid?

I have a former classmate who works abroad. She often receives SMS messages from relatives asking her to send money. The sender even used some personal information that only my classmate and her relatives will know. My classmate is fortunately a cautious person. She called her relative and she found out that her relative did not send any such SMS.

Now who would get a hold of her Cellphone and some information about her. The only thing she could recall is the company she hired to send a package to her country.

Firefox 4 vs IE 9 vs Chrome vs Opera 11

If you download Internet Explorer 9, Firefox 4, Google Chrome, and Opera 11 you will find out that they all look the same. It feels weird really that find myself confused which internet browser I am currently losing.

The differences of course is under the hood and they are very subtle.

For me Opera is the best when it comes to downloading large files. It allows you to resume downloading from where you left off when you turned off your pc or logged off the Internet.

Firefox is the best when it comes to add ons. My favorite is Firebug. It is a very good add on if you are a developer.

Chrome is of course the original clean browser.

Internet Explorer 9 recently followed the interface design of the other internet browsers. It boasts a feature that will prevent advertising companies from tracking your surfing behavior. The only browser to have this feature at the moment.

But as I have said earlier, they all now look the same. It’s kind of funny. I never thought I would see this happen.

Upgrading Oracle's VirtualBox

As I have posted earlier, VirtualBox is a virtualization software. What it does is allow you to install multiple operating systems in one PC or server.

An update, VirtualBox 4.0.4 was recently released on February 17, 2011. To upgrade VirtualBox 4.0.3 to the latest version:

1. Download VirtualBox 4.0.4 from the official website.

2. Uninstall your existing VirtualBox. Don't worry this will not erase your currently installed Operating Systems.

3. Restart your computer. You will be asked to restart your computer after uninstalling the existing software.

4. Install VirtualBox 4.0.4. Your previous OS installations should still be there.

Running Multiple Operating Systems in One Computer

For a long time I was unable to brush up my skills in Linux because there was no available computer to install it. I did not want to make my PC dual booth since in the past it proved to come with a lot of hassle. Sometimes if something goes wrong with one OS it also affected my other OS. That is why I did want to do that anymore.

Fortunately, I recently stumbled upon VirtualBox. I was helping a friend create a forked process in her program and we needed to do it in Linux. And instead of installing Linux on a separate partion, we decided to use a virtual machine software instead.

VMWare is the most popular virtualization software but I wanted to look for something that is opensource and free. Luckily there is VirtualBox.

VirtualBox is the only free and opensource virtualization software. It is licensed under GPL 2. Development is currently being spearheaded by Oracle. It works with Intel and AMD processors.

I am currently using it to run Ubuntu 10.10 and Kubuntu 10.4. I am hoping to use it to run Android and Apple's IOS.

Firefox vs Opera : Downloading Large Files

When it comes to rendering web pages, I think Firefox is the best. Sometimes when I am using Opera or Chrome Browser there are some javascript codes that does not function correctly but seems to work fine when I am using Firefox.

But if you are going to download large files, I would recommend using Opera. Opera is able to continue from where it last stopped after you paused the download. Firefox, on the other hand would often restart the whole process.

Windows 7 Media Player

One of the things I like about Windows 7 is the new Media Player. The interface has been simplified so you get more screen space when you are watching a movie. As you can see from the above picture, the program does not display the controls when you don't need them.

But if you need the controls simply hover your mouse over the program.  It will display only the most essential buttons that you will need.

If you want to see the more advanced controls, just right click over Media Player. You will see the option to chance the Visualization or Enhancements like in the previous Media Player versions.

Another great thing about Windows Media Player 12 is that it supports more video and audio format like Divx right off the bat.
