The 2233RZ has the typical onscreen menu of modern Samsung monitors except that it is always located in the bottom right corner of the screen, next to the button labels. You cannot move the menu.
The setup options are grouped into six sections. The menu remembers your actions and opens the section you were in the last time you closed it.
The first section contains brightness and contrast settings and MagicBright modes. These modes are screen brightness presets that can be enabled with a quick button without entering the onscreen menu. This is a handy feature for a home monitor which is used for work, play, movies and what not.
The monitor’s default brightness is too high for normal work. You will have to lower it.
The second section is about color temperature and gamma. The first option allows to choose a color temperature out of a few available values. The second option allows setting it up manually with RGB sliders, and the third option allows to change the value of gamma, increasing the contrast of the image or making it lighter (the option can take one of three values).
Despite the lack of analog connection, the monitor offers a sharpness setting. You should not touch it unless really necessary. When Sharpness is increased above the default level, there appear annoying contours around letters on the screen. When it is decreased, the image gets fuzzy.
In the next menu section you can choose the menu language, transparency and display time, but the option of adjusting the menu’s position is missing here.
The next section allows you to reset all the settings to their factory defaults, assign a function for the programmable button (it is second from the bottom; its default function is to switch MagicBright modes but you can use it to switch the interpolation mode), enable a timer for turning the monitor off after a specified time, and select an interpolation mode. There are two interpolation variants: stretching the image to full screen with and without restrained proportions.
The last menu item shows information about the current operation mode. You can make sure that the refresh rate is 120Hz indeed.
