Adding Monitors; Planning For Additional Monitors - HP Z238 User Manual

Adding monitors

Planning for additional monitors

All graphics cards provided with HP Z series Workstations support two simultaneous-display monitors (see
Connecting and configuring monitors on page
The process for adding monitors depends on your graphics card(s) and the type and number of monitors you
add.
Use this process to plan for adding more monitors.
1. Assess your monitor needs.
Determine how many monitors you require.
●
Determine the kind of graphics performance you want.
●
Note the type of graphics connector used by each monitor. HP provides graphics cards with
●
DisplayPort (DP) and DVI interfaces, but you can use adapters and third-party cards to interface to
other graphics formats, including DVI-I, HDMI, or VGA.
TIP:
compare the cost of acquiring adapters with the cost of getting a newer monitor that doesn't need
adapters.
2. Determine whether you need additional graphics cards.
Consult the graphics card documentation to determine how many monitors you can connect to the
●
card.
You may need to acquire adapters to match the card output to the monitor connector. (See
Matching graphics cards to monitor connectors on page
If necessary, plan to acquire a new graphics card to support additional monitors.
●
The maximum number of monitors that a graphics card supports depends on the card. Most cards
●
provide outputs for two monitors. Some provide three or four outputs.
NOTE:
either Dual Link DVI (DL-DVI) or DisplayPort output. To get native resolution with DVI, you must use
a DL-DVI cable, not standard DVI-I or DVI-D cables.
HP workstations do not support all graphics cards. Be sure that a new graphics card is supported
before purchasing it. See
Some graphics cards support multiple monitors by multiplexing the monitor signal across multiple
outputs. This might reduce graphics performance. Consult the graphics card documentation or look
up information on the card according to the procedure in
on page
Be sure the card outputs match the input required by the monitors. (See
connection requirements on page
The different models of HP Z series Workstations have different limits on the mechanical size, data
speed, and power available for additional graphics cards. Note that the usual practical limit for
graphics cards is two per workstation. See the Maintenance and Service Guide for expansion card
slot identification to be sure a new graphics card will work for your workstation.
