Operator Controls
The monitor comes with a complete OSD (On Screen Display) menu. Listed below are all of the menu functions included in the OSD.

1 (Screen Control)
2 (Distortion)
3 (Color Control)
Color Temp
RB Adjustment (Red/Blue)
Sync on Green
4 (Landing)
Top Left
Top Right
Bottom Left
Bottom Right
5 (Function)
Signal Select (BNC/D-SUB)
OSD Position
Display Frequency
Reset (Factory Defaults)

So as you can see, it has pretty much everything there that may need require adjusting; some you will probably never use. I found the factory defaults to be just fine, except for a brightness/contrast adjustment for my own personal preference. The menu is easy to use, and the manual explains the OSD very well, so you shouldn't have any issues here whatsoever.

DisplayMate Tests
Using the handy utility, DisplayMate, I went through all of its tests and was able to have a good close look at the display quality of the monitor. For all of the tests, I ran them at various resolutions and color depths. I have broken it down below into the various sections tested, and then summarized my findings.

Geometry & Distortion
This test displays various line patterns and geometric shapes, which gives you an accurate representation of the monitor's ability to properly display geometric shapes. The monitor performed excellent in these series of tests with no visible geometric inconsistencies found.

Sharpness & Resolution
During these tests, the monitor was put through various patterns and lines. The most noticeable thing you will usually see here is Moiré. Moiré occurs when there is interference between the phosphor layout and the video signal. The iiyama has an adjustment to compensate for this, and it did a fairly good job of it. There was a small amount of Moiré here, less than that with the the Pro 450. I had corrected this by adjusting the Moiré OSD control.

Screen Pixel Resolution
This test is similar to the Geometry test. It displays various line patterns and shapes. Here again, you are looking at the Moiré effect - jagged lines, rippled effects in the images, and lines that start to mesh together. Some of the patterns brought out the Moiré effect more than others did. Finding a monitor that does not display this effect in certain patterns is not an easy task.

Color and Gray-Scale
Now we get into the monitor's ability to display colors. One of the most important things to look for here is misconvergence. Misconvergence is essentially the misalignment of the red, green, and blue electron beams. The 510 performed very, very well here. There was a minimal amount at the edges of the screen (where it's most common), but nothing that causes visible problems elsewhere.
