This is AnandTech's first monitor review, and with what a great monitor to start it off! We are going to take a look at iiYama's VisionMaster Pro 450. Thankfully, this is one area of computers that isn't advancing at 90 miles an hour, requiring a weekly upgrade. But the market is changing in that purchasing a larger monitor is more common, and the fact that they have definitely lowered in price adds to that appeal.

The 19" monitor market is quite large these days, considering every manufacturer is making at least one 19" model; there are so many to choose from. Making that choice is a very, very tough decision. Buying a monitor can be the most expensive thing to add to your PC. That's why no matter what you read, try to test the monitor before buying it. I can't stress this enough - if you have to sit in front of it for a long period of time, you might as well buy something you enjoy looking at.
The VisionMaster PRO 450 uses Mitsubishi's DiamondTron NF TM Tube, which is a natural flat tube. Is it more flat than the older Trinitron tube? Yes. I have viewed this monitor along side a 21" Sony Trinitron and a ViewSonic SonicTron tube and there is no comparison. They look like bubbles beside the VisionMaster Pro 450. During the first few viewing hours, you actually get the impression that the tube is concave, but you get used to it; and after your eyes adjust, there is no turning back. |

iiYama has been around for over 20 years. They are the US subsidiary of "iiYama Electric Corporation" of Nagano, Japan. The company's track record is very good. They are recognized as a quality monitor manufacturer. So not to fear - you are not sinking your money into a company that has no idea how to construct decent monitors.

However, it has the twin analogue and digital signal inputs which I believe were discontinued with the later 454 model, possibly for cost reasons. The digital connection, even though ironically it is then converted back to analogue inside the monitor, results in a marginally (but still useful) purer image especially with text. https://telldunkin.usushandyman - Saturday, July 18, 2020 - link
