Display Internal HP ProBook 4320s:
13.3-inch diagonal LED-backlit HD anti-glare (1366 x 768 resolution)
HP ProBook 4420s:
14.0-inch diagonal LED-backlit HD anti-glare (1366 x 768 resolution)
Optional HP Privacy Filter
External Up to 32-bit per pixel color depth
VGA port supports resolutions up to 2048 x 1536 at 75 Hz, and lower
resolutions at up to 100 Hz.
HDMI port supports direct connection to high-definition displays with up to
1920 x 1080 resolution and 7-channel audio with one convenient cable (not
included).
NOTE: Resolutions are dependent upon monitor capability, and resolution and
color depth settings.
Memory Standard DDR3 PC3-8500 (1066 MHz) * or PC3-10600 (1333 MHz) * SDRAM
Two SODIMM slots supporting dual-channel memory
1024 MB, 2048 MB, and 4096 SODIMMs
Maximum Upgradeable to 8192 MB with 4096 MB SODIMMs in slots 1 and 2
Dual-channel Maximized dual-channel performance requires SODIMMs of the same size and
speed in both memory slots.
* Memory speed is processor dependent.
NOTE: Due to the non-industry standard nature of some third-party memory modules, we recommend HP
branded memory to ensure compatibility. If you mix memory speeds, the system will perform at the lower
memory speed. Full availability of 4 GB or more of memory requires Windows Vista Business 64-bit or
Linux. With Windows 32-bit operating systems, the amount of usable memory is dependent upon your
configuration, so that above 3 GB all memory may not be available due to system resource requirements.
Communications Realtek Ethernet (10/100/1000 NIC) *
Optional 56K V.92 modem **
* The term "10/100/1000" or "Gigabit" Ethernet indicates compliance with IEEE standard 802.3ab for
Gigabit Ethernet, and does not connote actual operating speed of 1 Gb/s. For high-speed transmission,
connection to a Gigabit Ethernet server and network infrastructure is required.
** Designed for downloads from 56K modem compliant sources. Maximum achievable download
transmission rates currently do not reach 56 KB/s, and will vary with line conditions. Modem availability is
subject to country regulatory approval.
