Do you mind posting your calibration settings for others to try.
Which model T430S do you have? When you say you have discrete graphics, do you mean is has the dual GPU Optimus graphics?
I am not sure of the exact model number, but when I say I have discrete graphics I mean I have just the one Optimus GPU. the 5200 I believe the number is.
Can you try setting the BIOS to integrated only and disable Optimus and OS detection for Optimus. This setting essetially converts it to an Intel HD4000-only machine. I am curious to see whether the T430s can then still drive 2 external displays.
When I do this on my T420s optimus on a Series 3 Plus dock, limitiing it to Intel HD3000-only, I lose one of two external DP displays.
Results with the i7 t430s and integrated Intel HD 4000 Graphics (16GB RAM)
WEI: Processor: 7.2, Memory: 7.5, Graphics: 6.5; Gaming Graphics: 6.5, Primary hard disk: 7.9
3DMark Vantage: P4200 (Graphics 3464, CPU 11570)
Now it seems obvious why the Nvidia Optimus is not an option on the i7 T430s. $200 seems like a lot to pay for improving the score by less than 200 on a benchmark like this...
Are you able to run 3 displays simultaneously on your i7? If so, what is your graphics driver version and how did you configure it? I find it strange that the i7 integrated graphics option may be required to power 3 displays rather than the i5 with dedicated graphics, but that may be the way it is. If so, I may push for a return and get the i7 instead.
Disabling Optimus in BIOS makes no difference. I can still only power 2 displays total, either external (internal LCD off), or 1 external + internal.
I can power 3 displays at once, but not at their highest resolutions. See my previous post in this thread for detailed info.
Your previous post is about the WEI figures.
Regarding the displays, what three external displays are you using? How are the connected? What are their native resolutions?
Hi. Would you please share which 16GB kit you ordered and from where?
I want to add a single 8GB to make it 12GB in total (4GB original).
Does anybody have suggetsions? Just wanted to make it compatable with the original Samsung 4GB RAM. Thanks
