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.
As all engineers do, if there’s a problem we always strive to find a solution to help resolve it…
Listed below is a step by step guide on how to greatly reduce the input lag on the LG 42LW650T TV:
N.b – This test was carried out on TV firmware version: 04.00.18. I am aware there are updated versions of the firmware, however, I’m still very happy with 04.00.18
1). Connect your HDMI cable from your PC/console(s) into the HDMI 1 port of the TV. Don’t confuse this with the HDD/USB IN 1 (shown in the red circle) or with any of the other HDMI 2,3,4 ports. HDMI IN port 1 is shown in the green circle below:
2). Rename the HDMI 1 input to ”PC” – this can be done by first pressing the ‘‘input” button (situated at the very top of the TV’s remote control – see below)
Then move the cursor over HDMI 1 and press the green button (found at the bottom of the remote) to rename it to PC.
N.b – In the photo below you can see my HDMI 1 port has already been renamed to PC (As its showing a picture of a laptop and has ”PC” written in the top right corner). Before you rename it to PC, there shouldnt be a picture of the laptop there, it will show a HDMI port instead.
After pressing the green button, this brings up another menu (below) and allows you to change the name of the input, scroll along and select ”PC”.
3). Very important – once you have done this, press the ‘quick menu’ button (Q-menu) on the remote and make sure ”AV mode and Picture mode” are set to ‘Game’ mode (See photo below). Setting these both to ‘Game’ mode auto turns off the TrueMotion setting, which is what we want ! If you don’t set AV & Picture mode to Game then you probably wont see any improvements!
Calibrate Display settings on consoles.
4). If your playing on an Xbox 360, go into Console Settings –> Display Settings and make sure 1080p is selected and 42” is put in as your screen size.
5). Similarly if your playing on a PS3, go into Settings –> Display settings –> video output settings, and make sure you set the TV output to 1080p and the screen size to 42 inches (see photo below).
N.b – Some games are made at 720p resolution, so setting your display settings to 720p instead of 1080p may also help !
Once you have done all of this, you will see for yourself how much the input lag has greatly reduced. On my TV I can’t notice it at all any more (obviously there is some there, however, its unnoticeable to the human eye as the delay is so small).
**Input Lag Before**
Since I didn’t record any digital footage of the input lag (It’s stored only as horrible memories in my mind) before sorting the input lag out, just to give you an idea of how bad it was – have a look at the Battlefield 3 video below courtesy of ”Patricio1790”. Although his TV isn’t the LW650T, this is how bad my input lag was (camera was sluggish/unresponsive and made manoeuvring around a pain in the backside, guns wouldn’t fire immediately either).
I was aware BF3 had more intense input lag issues and a patch was released by DICE to clear it up, however, I had pretty much the same input lag issues with the following games: Gears of War, Forza, GT5, Call of Duty, Fear 2, Dead Space 2, Uncharted 2 and BF3 (to name a few). All of them were unplayable due to the severity of the lag.
**Input Lag After**
Finally got round to setting up a proper YouTube channel for iTech Online so our first upload was, yup you guessed it, the video below ! We also measured the input lag to be around 0.018-0.019 seconds (18-19ms) using a CRT monitor, this was done once the camera decided to run out of battery, so I may run it again and record it next time. As you can see in the video below, button presses are much much more responsive now and gaming is a lot more enjoyable.
