you did not say dual port GPU card nor using 2x GPU cards.
so must be DAISY CHAINED Display card, there, NOT TOLD IT.
on all PCs on earth , (NO OS told at all why?)
the correct software drivers for the GPU card must be loaded
from the card makers site
if no card then from Lenovo.
yes horz = DP? daisy chained. mon to mon link.
you meant
IntelliStation Z Pro Type
6221 (made 2004, 14 years ago)
that>?
nobody knows what is inside any desktop (added)
for sure GPU cards 12 makers, + and vast models.
if all IBM is it?
the card choices are listed in the free IBM manual
Video adapter: Accelerated graphics port
(AGP) Pro 50 video with one of the following:
v Matrox Millennium G450 (DVI-I) 4X with 32
MB double-data-rate (DDR) synchronous
dynamic random access memory (SDRAM)
video memory and a single DVI-I or dual
analog connectors (or dual VGA monitor
capability with the pigtail cable that came
with the system)
v NVIDIA Quadro4 NVS 280 (LFH-60), AGP
8X, with 64 MB DDR SDRAM video
memory and dual analog connectors (or
dual digital monitor capability with the
purchase of an additional pigtail cable)
v NVIDIA Quadro4 980XGL (DVI-I), AGP 8X,
with 128 MB DDR SDRAM video memory
and dual DVI-I connectors
v NVIDIA Quadro FX 1000 (DVI-I), AGP 8X,
with 128 MB DDR2 SDRAM video memory
with dual DVI-I connectors
v NVIDIA Quadro FX 1100 (DVI-I), AGP 8X,
with 128 MB DDR SDRAM video memory
with dual DVI-I connecctors
v NVIDIA Quadro FX 3000 (DVI-I), AGP 8X,
with 256 MB DDR SDRAM video memory
with dual DVI-I connectors
v 3Dlabs Wildcat4 7110 (DVI-I), AGP 8X, with
128 MB texture buffer DDR SDRAM video
memory and 128 MB frame buffer video
memory, and dual DVI-I connectors.
only Display port allows daisy chaining monitors
but there is no such card from IBM in 2004
worst of all AGP is dead technology.
how you get DP here?
we can not see back of your PC nor what is inside
and desktops can be expanded greatly , no limits. really. if savvy
worst of all this relic has not one, PCI-express slot.
so only old relic cards fit.
