Testing Methodology

Use the following link for a description of our testing methodology and the equipment we use, and for a brief explanation of what the specified and tested parameters of LCD monitors mean: X-bit Labs Presents: LCD Monitors Testing Methodology In Depth. If you feel overwhelmed with the numbers and terms this article abounds in, check out an appropriate section of the mentioned article for an explanation.

You can also check out the Monitors section of our site if this review doesn’t cover the model you are interested in.


The monitor is based on a 22-inch TN matrix. Its specified response time of 3 milliseconds (GtG) indicates Response Time Compensation. Well, the monitor just wouldn’t be fast enough to switch between frames at 120Hz without RTC.

The brightness, contrast ratio and viewing angles specs are all normal. It is good that the manufacturer specifies both static and dynamic contrast.

Besides the high refresh rate, it is a noteworthy fact that the monitor is equipped with a dual-link DVI only. It does not have an analog input. The dual-link version of the interface is necessary to ensure the high refresh rate. At a resolution of 1680x1050 and a refresh rate of 120Hz the video data stream amounts to over 4.7Gbps whereas the peak bandwidth of the single-link DVI is somewhat lower than 4Gbps.

This should provoke no compatibility issues. Every modern discrete graphics card has dual-link DVI ports. Connecting a SyncMaster 2233RZ to them would not be different from connecting any other monitor. Integrated graphics cores and notebooks mostly have a single-link output, but this only means that refresh rates higher than 75Hz will not be available with them.

A Dual-Link DVI-D cable is included with the monitor. If you have to purchase it separately, take note that you will not be able to get the 120Hz refresh rate from this monitor with a Single-Link cable.
