Multiple Screen Configuration on M75e

I have a client that has a ThinkCentre M75e. They are using 2 screens from the built in video. They are mentioning that one of the screens dims on a regular basis and it makes it hard to view that one monitor.

 

Where would I find the setting that may control this or do I need to add a separate video card to resolve her concern?

Re: Multiple Screen Configuration on M75e

hey donclayton,

before delving further, I would like to know what happens if the monitors were swapped?

Monitor A (problematic) goes to slot B where Monitor B (good one) used to be. Does Monitor A dim ?

Re: Multiple Screen Configuration on M75e

Several colleagues, as well as myself, were just given ThinkCentre M75e systems for use in our classrooms along with our electronic whiteboards (SmartBoards).

 

I used the VGA connection to go from the computer to the SmartBoard with no problem.  I used a DisplayPort to DVI cable for the monitor and got nothing.

 

When I looked in the BIOS setup, I saw that Surround View was disabled and there seemed to be no way of enabling it.  The DVI port doesn't work even when hooked to the computer by itself.

 

I notice there are different primary video controller choices, yet there is no explanation as to what each one means. 

 

How do I get the computer to recognize both the monitor and the SmartBoard?  '

 

Thanks.

Re: Multiple Screen Configuration on M75e

surroundview is something used when you use a certain line of the ATI graphics card to enable 4 LCD display. If you don't have a PCI-e ATI graphics card installed then this option is not enabled.

Right click on the desktop choose your ATI display property, and in there see whether there is option to enable the GPU to run the desktop extended or clone mode.

Also press Windows key + P do you see a choice for clone and extend mode?

Re: Multiple Screen Configuration on M75e

I have a similar problem.

I have 3 lenovo thinkcentres and all three dim upon wakeup.  That is, after the screen saver kicks in and log in is required to get back on.  I have been battling this frustrating problem for several months.

 

Today I found the "Power Manager"  I slid the bar to "High Performance" and then under "Advanced Settings" I clicked "Global Power Settings" tab.

Under "Power Management options" I clicked "Apply the settings to all power plans"

Under "Dynamic Brightness Control" I unchecked all boxes.

 

So far this seems to have solved my problems.  I assume it would apply to dual monitors.  I have one with dual monitors and it seems to be working fine.

 

Hope that helps someone!
