Question about LG 22" FLATRON LCD Monitor

1 Answer

Flatron 22" 16:9 occasionally goes black for 1-2 seconds

I just purchased a 22" LG FLATRON W2253TQ and ran into a snag within the first day of use. I was just surfing the internet and enjoying my new multitasking ability when suddenly my screen went black. I glanced at my power LED to find it still lit, and there was no real way for me to bump the power cord.
Then, to my surprise, the screen came back on. I want to say it was black for only about 1.5 to 2 seconds.
I thought "Oh, no big deal, at least it's back. No problem."
Since then, it's done the same thing multiple times, and it seems to do it about once per hour at least. Occasionally, it does it multiple times in the same minute. The time between "power-downs" doesn't seem to be consistent, and it has happened under varying degrees of graphic intensity. It does not appear to be heat related, either.
Other random information: Running windows 7. I have the latest monitor and graphics drivers. Neither the power cord or the DVI cord are loose on either end, and the black-outs don't happen in reaction to physical movement. I am running dual monitors on my ATI 3300 built in card. This card uses shared system memory, and according to the Catalyst Control Center, is using about 2 GB of my 4 GB of ram.
Some possible thoughts that I wanted to explore before sending it in: Could it have something to do with my underpowered graphics card or the shared memory? Is it likely that it's a monitor issue? Is this a common problem?

    Alright, bit of an update. From my testing, this happens more often when less RAM is available. Logically, it seems to be the graphics card, and specifically, the shared memory. I'm mostly just looking for confirmation at this point.

RAM if under heavy duress when it gets stuck by Page loads , which means " virtual Memory" just dips in . It's like a person who coughs a bit under some common cold simply because it's resistance has gone low .
Kick up some more RAM or use a RAM Booster , or install a " cache" reguling software .

SOURCE: I have a flatron w2253tq and have "analoge power

Is the monitor connected to the computer using a VGA plug (a smaller one, with 15 pins in 3 rows), or a DVI plug (wider one, with flat pins in 2 rows)?

From what you write, your monitor is switched to the analog input (VGA). It doesn't sense any signal on that input and hence goes to power down mode.

You need to go to your monitor's on-screen menu and select the digital input - you should see the picture then.

It could be some sort of "Demo" mode on the display, try going into the menu of the display and looking for settings relating to Flatron F-Engine, it has a demo mode that could be the problem. That is the most likely cause since its exactly half the screen.

I have a L194WT LG Flatron monitor. One day it


Same problem started happening two days ago and ever since. I called LG and the product falls under a 3yr product warranty according to them (from my original purchase date of January 20, 2007). They will send packing slips to me so I can send the defective unit back to LG. I was told I am eligible for a replacement monitor - which will be shipped to me within 10 to 14 days (consecutive days, not business) - although I'm not sure what I'm being sent in return. My suspicion is that this monitor issue is a known issue by LG and they are quietly replacing the unit to those who follow through by calling CS.

Tips: Have your original purchase date on hand (in the form of a receipt) just in case they want proof of purchase.

Monitor colors "pulse"


What video card do you have?? Some older video cards don't display very well at higher resolutions... You may want to get the latest video card drivers which may help the problem.

You can find out what card by opening display settings and going to the screen that shows the 1280x1024 resolution.

Let us know how it goes
