Backlight Bleeding


I did some research online and found that most LCD monitors suffer from this. From the most expensive to the cheapest ones. I still trying to decide whether I should return it for a replacement or not since the next one might come worst. When I bought...

This is a great monitor. It has very good brighting and good contrast. The picture quality is very good for the price

The only bad thing that I have found is the it has a big portion of the middle with backlight bleeding. Is not noticeable in bright images but if you plan to see movies with dark scenes is very bad. However if you see the monitor from the right is less...

Great Viewsonic Product


Inexpensive as far as LCDs go. Bright Display and great image quality. Built-In speakers work great for the non-audiophile

Not the best monitor on the market, but cheap enough for most people to think about buying. I would not recommend for playing games, but is great for all "office" type applications.

Very good Monitor. I currently have 6-8 of these setup at my work for dual monitors. No dead pixels between all of them. Very bright, clean picture. Would definitely purchase again

I wasn't able to buy from My work has agreement with other vendor. If did "Net Terms" for businesses, I would switch over quickly though

Very good for the price


This is a very good monitor for the price for average office and light gaming use. It's not for hardcore gamers (choose a 2 millisec refresh rate for that). I found that this monitor looks best with a 60 Hz frequency instead of the standard 70 Hz (if...

Very clear, high resolution for both pictures and gaming (hence the 5 millisec refresh rate). FOR THE PRICE, this is an excellent montior. I personally don't like the widescreen and the selection of normal screens is harder to find. The viewsonic brand...

The speakers are really under powered (very tin-metallic sounding) DO NOT BUY THIS LCD FOR ITS SPEAKERS = they stink hardcore! Make sure you have your own speakers (at least 5 watt for good sound) ; This first LCD I ordered had zero dead pixels but...

Works Great!!!!!!!!!!!!!!!!


I see feedback about these being cheap looking, they are great monitors with plastic frames, get over it. I see no problem at all, they are more than sturdy enough for my taste, I look for function not esthetics's. Go spend a $100 more for a better...

I bought 4 of these for 2 workstations (dual monitors) and I could not be happier. Very bright, you walk in the dark office and hit the mouse to do some work and you almost go blind. Not a dead pixel in the bunch

Very nice monitor


Very nice monitor at a reasonable price.

This monitor has outstanding brightness, contrast and color ; It self-adjusts very well to many different resolutions, and look great even at its non-native resolution

Don't even think of buying this for the speakers. They are terrible. If you EVER listen to music, don't use these speakers

Great Monitor for Price


This is a great monitor and I love it, I want one like this at work, bigger, better. I only have a 15" flat screen. Maybe someday. I order on Tuesday and recieved by Thursday ; Fast delivery

Got rid of that old big monitor, this works good, what I was looking for

Consumer review (



I replaced an aged 17 inch Sharp that liked to flip colors from washed out grey (which was supposed to be white) to an off yellow. After plugging in this second Viewsonic (my other one is a VG2230) I was blown away.

Extremely bright vibrant colors. Black levels also very good. Newegg got it from their NJ warehouse to my doorstep (Wash DC) in 2 days. No dead pixels either. If I could marry it I would. Least with a monitor you can turn it off when your not viewing it

No DVI cable included
