The following table lists the detailed discrete graphics specifications on your Alienware Area-51 AAT2250.
NOTE: For proper functioning of four monitors on your computer with the below graphic cards, to ensure that the display
pixel clock speed remains below 1335 MHz. If the pixel clock speed of one display exceeds 1335 MHz, only three monitors
are displayed. Similarly, if the pixel clock speed of more than two displays exceed 1335 MHz, a maximum of two monitors are
displayed.
NOTE: The computer is equipped with a Thunderbolt 4 port that supports DisplayPort functionality. However, since the
computer always has a discrete graphics card that is installed, the primary video detection sequence is set to prioritize the
discrete graphics card. Therefore, when a monitor is connected to the onboard Thunderbolt 4 port, it will not be displayed in the
preboot environment (BIOS setup and shell mode).
