How to greatly reduce input lag on the LG 42LW650T 3D TV

A while back when I was browsing the web and retail stores for a 3DTV, my main concern was the input (or display) lag of the TV – since I would be using the TV primarily for gaming. So it was essential for me (and will be for a lot of you gamers out there) to do a bit of research on the TV’s that are good for gaming and also the work-a-rounds to lowering the input lag so that you can game happily.

Input lag occurs in every LCD or HDTV and is the time difference between a signal input being pressed (i.e a button on your controller) and the time is takes that signal input to be displayed on the screen. For example, if your playing a racing game and are approaching a left hand turn, when you press left on your controller you want the car to turn left as soon as you push left, not a second later or you will crash, probably. The same in shooting games, when you pull the trigger you want the gun to fire immediately, not 2 seconds after you tapped the fire button. The good thing is, most TV’s come with either a gaming mode and there are a few things you can do to greatly reduce the input lag to a point where you cannot even notice it (at least with this TV you can). Thus, making gaming an absolute joy.

Before I purchased the TV, I read a few reviews specifically about the input lag on the LG 42LW650T model (the TV I ended up purchasing in the end) where some people managed to reduce the input lag of this model so that it was not visible to the human eye, and others complained they couldn’t do it at all and inevitably had to return the TV.

So, after unboxing the TV I touched nothing, no settings, no nothing and deliberately set up my Xbox 360 and PS3 right away so I could get an idea of how bad the input lag was. I could instantly see the input lag, to a point where I was like ”this is bad, like really bad” – when rotating the camera and trying to manoeuvre my character about the screen, there was a very annoying 1-2 second delay which caused it to be rather clunky and I always felt the TV was a second or two behind me whenever I hit a button on the controller.

How to install Mac OS X Theme for Ubuntu 11.04

Upon installing Ubuntu 11.04, the first thing I done was play about with different backgrounds and themes. After wanting something a bit more than what was available, I decided to try out the Macbuntu theme.

Which, funnily enough, makes your Ubuntu desktop look similar to a Mac running OS X.

Real Deal: This is Ubuntu 11.04 Running the Macbuntu Theme

How to locate and reset Acer 5920G CMOS Battery – without dismantling the whole laptop

The other day I had to reset the CMOS battery on my Acer 5920G laptop. I found a nice little short cut in getting the job done quickly and efficiently. After reading a couple of tutorials online most of the people said that I would literally have to completely dismantle the laptop (apart from the monitor of course), which seemed a little long-winded, seeing as that I was able to spot the CMOS battery just by removing the back cover.

The problem lies in its location. It is extremely difficult to get your fingers in where its connect to the circuit board without dismantling the case and circuit board (”No disassemble number 5” – Johnny 5). This guide will show you how to reset the CMOS battery by only removing the back cover of the laptop.

How to permanently turn off wi-fi power management in Ubuntu

How to permanently turn off wi-fi power management in Ubuntu – Fixes loss of wi-fi connection when on battery power.
 
My better half recently installed Ubuntu 11.04 (Natty Narwhal) on her notebook and quickly realised that when she removed the AC power lead the wi-fi connection would cut out, only resuming when she plugged the power lead back in.  This meaning she could not access or use wi-fi whilst running on battery power alone – which kind of defeats the purpose of having a laptop/notebook if you need the power cable plugged in at all times to surf the web.
 
 Anyway, the root of the cause is that Ubuntu’s new default power management setting turns ‘on’ the power management for the wi-fi device when on battery power. Meaning you lose the wi-fi connection if you unplug the AC power from your laptop/notebook.  There is a simple little solution that can fix this problem. 
 
All we need to do is run a couple of commands and create or edit a file in /etc/pm/power.d that will basically tell Ubuntu to turn the wi-fi power management off and to keep it off permanently when in battery mode, so we can use the wi-fi wherever and whenever we choose to.To apply the fix, follow the steps below but make sure you do NOThave the AC power plugged into your laptop/notebook, follow the steps on battery power.

How to boot and install Windows (XP/Vista/7) from a USB stick

So you want to put Windows XP/Vista/7 onto a USB stick but are a little bit unsure on how to get it done? Well look no further, this guide will help you to do just that, no matter how inexperienced you may be using computers.

This can come in real handy if you need to reinstall Windows but don’t have an installation CD or maybe your using a notebook that doesn’t have a CD/DVD drive. Or maybe you have a Windows installation CD but want to make a back-up of it incase the disc gets damaged.

Things you will need:

1). A USB stick (preferably up to 4GB, although my Windows Xp SP3 was only 622 MB’s roughly so a 1GB stick would have work fine – Windows Vista and 7 will be bigger in size). Note – if your USB stick has any files on it just now, back these up as all data on it will be erased during the process.

2). WinToFlash (http://www.wintoflash.com/download/en) – This is an excellent freeware program that has worked flawlessly for me time and time again and can be downloaded here, or from the downloads section of iTech Online.

3). A Windows installation disc – If you do not own a Windows disc you can also burn a .iso image file to the USB. Once you have your .iso file you can either burn it to a CD (if you have a CD/DVD drive) or if you are using a notebook (with no CD drive), please download and install Daemon Tools: (http://www.daemon-tools.cc/eng/downloads) (this will act as a virtual CD/DVD drive and will allow you to copy the Windows installation files from the virtual drive onto the USB stick as explained in the steps below).
