Possible to run two external monitTecra R850-S8540

I have a Tecra R850-S8540 and two external monitors.

 

I'd like to extend the desktop across all three displays (both monitors and the laptop LCD).

 

When I try to activate the 3rd screen and hit apply it says "Unable to save display settings"

 

I was figuring that I could use the AMD Radeon HD 6450M display adaptor for the LCD and external monitors but seems to be not the case.

 

Saw an Intel video driver on the support site - was hoping that installing it would resurrect a dormant Intel MoBo display adaptor that I could connect via the VGA port (the HDMI port is already being used to connect to the first monitor).

 

Has anyone done this? Is it possible (does this laptop even have dormant Intel video hardware that could be used for this purpose)? Or is this an exercise in futility? :smileyhappy:

Hi Peter,

 

I am getting the exact error "Unable to save display settings".

I am using a DsiplayPort cable and a High Speed Port Replicator II.

 

Although Tohsiba adivertises R850-S8550 as being capable of running 4 screens at once, I can't choose more than two :smileysad:(

 

"Up to 4 Screens

When 2 screens just don’t give you enough viewing real estate, there’s no need to worry. These Tecra® laptops let you expand your view up to four."

Is that just false advertising? or what am I doing wrong?

 

My catalist center version is:

 

Driver Packaging Version 8.801.2.3-110302a-114754C-Toshiba

I also got this Laptop R850 with the Idea that I can run two external monitors and my laptop screen.

 

Now I can't find any instructions on how to set this up....!

Re: Possible to run two external monitTecra R850-S8540

gman, I'm glad you posted in this thread again and got me to see it. I posted incorrectly previously.

 

First, ensure you have a model with AMD graphics. You should be able to have three monitors total (including your internal) without a docker or four monitors total (including your internal) with a docker.

 

If you're not using the docker, connect one monitor to the VGA/DVI and the other to the DisplayPort.

 

If you're using a docker, connect one to the VGA/DVI port on the docker, one to the DisplayPort on the docker, and to the DisplayPort on the notebook.

 

If you have trouble, try updating the display driver.

 

AMD Display Driver(06-29-2011; 131.17M)

 

If it still gives you trouble, please note any error messages you receive and what driver version you're using and post here.

Peter,

 

I've got a similar problem as gman, I've followed your advice and have still come up empty.

 

I have a Tecra R850 with AMD graphics and a Hi-Speed Port Replicator II. I tried updating the driver and installing Catalyst but was still unable to run more than 1 external monitor alongside the laptop monitor (I have since reverted to the older driver because the newer one was causing other problems). I have tried all combinations of monitors and ports (except for the DisplayPort which will require further investment) and can still only run 2 displays.

 

I currently have an external monitor connected to the VGA port of the replicator, I would like to connect another via the DVI/HDMI port on the replicator and still use the laptop display (3 displays).

 

Can you offer any other advice on how we can enable the second external display on this machine?

 

Thanks,

Unfortunately I only know exactly what I posted in the previous post. I haven't done it myself either. However, it might not work using the VGA/DVI of the docker with the VGA of your laptop. It might only work with a single VGA connection.

 

You might want to contact customer support to see if they could provide you with additonal information.

One year later and still cannot activate three monitors at the same time

Peter, your response is really confusing by avoiding explaining the error in the first place.

"Unable to save display settings" error comes every time you choose more than two monitors at the same time, no matter if you are using the port repliactor or just Display Port + VGA + Internal.

 

SO, R835, R850 and R950 don't really support more than two screens at a time, Toshiba is just doing fake advertising.

Besides all of above come with SATA III, but Toshiba again disables it from BIOS so you cannot use any of SATA III nowdays SSDs! 

That's a shame!!!

Hi, I just came across this thread as I was also searching for a solution to this. It is now Dec 2012. I just got a Tecra R940 and bought a hi-speed Port Replicator II with the hope of connecting 2 external monitors. The website says " You may be able to connect two external monitors at a time depending on your notebook model". http://us.toshiba.com/accessory/PA3916U-1PRP/

 

My laptop comes with AMD Radeon HD7570 graphics card and the driver is up to date - so i was confident it could  support these 2 external monitors. However, I am getting the same problem. it seems like the docking station can only support 1 external monitor. This is really disheartening considering the money I invested buying the docking station and two 24 inch monitors. Please can somebody advise if there is a solution to this or is it really fake advertising? thanks.

Same problem here. It works in Linux, so it just seems to be a windows driver issue. Aparently the Toshiba marketingstuff in which they make false promises comes from the hardwaredepartment, and the people who program the drivers can't keep up.

 

Thanks for the great 'support' Toshiba.
