Display failing after a couple of years.
358348
For the first two years it worked fine. After that the display started to fail.  I can no longer read the display, even with fresh new batteries installed.  It's now useless.  I probably got my money out of it, but expected it to last more than a couple of years.

this works fine when it works, I purchased one from a different seller in 2015, I noticed yesterday that the display goes out now when a load is put on it. I'll go with a different make.

I bought my Dell E172FP monitor less than two years ago and it has died -- appears to be a power supply issue.  It was good as long as it lasted, but I expected it to last longer.  My old CRTs are still running after 10 years.

Original review (two updates follow):
I bought one of these in January 2011.  It worked great for the past 2.5 years, but is now developing problems (bad pixel colors for one of the two attached displays).  At $250 retail, I may have to write it off as an "$8.33 per month rental."  The most frustrating part of the problem is that I haven't been able to find documentation for the length of the product warranty -- everywhere I look seems to refer elsewhere.  I've sent an email to IOGEAR's support; if the unit is still in warranty I may be able to raise the star rating.

Update #1 - September 13, 2013:
IOGEAR's support was very responsive to my requests for info on the unit's warranty (which I found out was 3 years), and when I requested an RMA.  They shipped a replacement unit to me one or two days after they got the failing device.  Unfortunately, the replacement is as bad or worse than the original -- bad pixels show up as quickly, maybe sooner after boot-up, than they did before.  So, I'm now out the original price plus the postage that I paid for the warranty work.  Guess I'll try another brand / model of KVM for the replacement.

Update #2 - December 21, 2013:
Since September, I've replaced the video card that was displaying the green pixels.  I put the (RMA replacement) KVM back in the sequence and everything has been working fine again.  I can't explain why the problem surfaced after two and a half years (presumably something going bad in the video card), or why it only showed up -- intermittently -- when the KVM was in the sequence (i.e., no problems with the card wired direct to the monitor).

Segments of the LCD display stopped working after about 2 years, but it still works great.

I've been using this for almost 2 years and it works well. The display turns off after a minute of inactivity to save power.

It was awesome for 2 years but then the display started to to go.  We'd miss half of a given number on display so an 8 looked like a 3 on the oz. portion.  That was hard enough to decipher but battery changes made no difference so it's now useless.  If you want one that's good for 2 years and then need to throw away, this is the one.  Not sure if anyone makes a better one so giving 3 stars.

Display started to fail on second use. Fortunately, the backlight LED still turns red/green so it is still useful.

Display problems since new. Dell tried to fix it, but couldn't, and then refused to replace it. Now I'm stuck with a $800 paperweight.
This was my first Dell, and the last.

Display stopped working after a couple months. I thought it might be the battery but a new battery did not fix the problem. Warranty says to contact the seller and they will replace or refund but I could not find any contact info on the page.

Just like a few other reviewers commented, my display does not work right (only parts of numbers display) after about 2 years of very light occasional use.  HP used to make good calculators 20 years ago - no more!

Terribly expensive and the display starts going bad after a year.

Lasted for about 2 years and the screen stopped working. It would not respond to touch but everything else was working fine. It would restart, charge, behave as a storage device when connected to the laptop. The screen just completely stopped responding.

I purchased this TV in May of 2008 and I loved it. In November of 2010 the LCD panel broke. The picture is darker on the left side and the image leaves trails. Sometimes the screen is black when I turn it on but after about half an hour the picture will come on if I turn the set off and then on again. They have since offered me a deal on their new 55 inch TV for $1400.

I purchased this back in December 2011. The TV sits on a stand in my master bedroom.  Only me and the wife uses it when we are getting ready for bed.  I've recently noticed that the "Frame" around the actual screen is coming apart. This TV is not hanged on the wall and has never been dropped, but I noticed a shadow in the corner of the screen one day when I was walking by.  The shadow was coming from the corner plastic bezel that has now popped out.  I tried taking the screw out and try to retightening it, but it won't tighten. This is the 2nd LG TV that has failed on me, so LG is no longer a brand I will support.
