Question: Where can I buy an audio cable?
Document: The monitor isn't a true LED. Its not half an inch thin like higher quality. In fact, its really LCD.Second, it comes only with a VGA cable. Who uses that any more? I had to buy a new DVI cable.
I never buy anything but ViewSonic monitors and have NEVER been disappointed. They are a super value, especially for the larger units...
For the money you can't go wrong with this monitor. Great color  and contrast. Really happy with this purchase and I had a friend buy one and he's very happy as well.
The monitor works well. I've had several Viewsonic monitors. They usually last a long time. I was disappointed to realize this monitor has no HDMI port. Pretty surprising nowadays. It does have VDI, so I had to buy special cables to get it to work OK.
In creating a garage workspace, we needed air cooling (see my other reviews) and a way for customers to view details on guitar work and references online for customers and owner. HDMI cable provided plugs right in. This works great allowing customers to see clearly from a few feet away without straining. It's a perfect office tool.
Did not last one year before brightness went out and the screen basically turned pink. The customer support at ViewSonic was terrible and no one truly wanted to help. Had picture turning off and on for while before the screen went bad. Overall, I am very disappointed and will never buy a ViewSonic product again. I went to ASUS and it is incredible.
I decided to buy this ViewSonic monitor because of the brand's good reputation, because I wanted something 'bigger' and because the price appeared to be right. Six weeks later, I am coming back to my four year old, smaller but superior in every other aspectHP W2207H 22-inch Widescreen LCD Monitor.
I love this monitor. Say goodbye to the horizontal scroll bar with this baby. My ancient 19&#34; CRT monitor finally died, forcing to to upgrade. I wanted max. viewing real estate and this monitor delivers. I could not be happier with this monitor. The price was great too with free shipping. Amazon rocks again as usual. Buy this monitor. You will not be disappointed.
The 27&#34; Viewsonic monitor is a very good buy. It is clear and crisp. The colors are excellent.viewsonic has always made good quality monitors.
-This is the second monitor we've bought in the last month (the other was a Samsung bought from Best Buy) that included a CVGA cord but not a DVI cord. The DVI cord is essential to gain the best image.Apparently these companies would prefer to waste their buyers' time to save a few bucks.
Answer: This is a video monitor with no speaker.  Your computer probably has a built-in low fidelity speaker, or you could purchase a set of external computer speakers.
