Lenovo T490S unable to display 5k on Dell U4919DW

2020-06-16, 7:52 AM

My Lenovo T490S is unable to display 5k on my Dell U4919DW. The max resolution I can choose is 3840 x 1080. 


Drivers are up to date, tried intallning graphics drivers from Intel and from Lenovo.

I'm in the exact same boat - I actually bought this laptop specifically to run my U4919DW. I've only had the T490 for a few hours and I'm on the cusp of returning it.


Some other things you might try that didn't work for me, but seem to have for others:

Recently, I did the windows update and it wiped out my settings.  So I had to do it over again.  I connect T490s to Dell U4919 via USB C. Here are the details.


Intel drivers that I have been using are downloaded from intel here:  https://downloadcenter.intel.com/product/126789


igfx_win10_100.8190 (I used this one for 3 months until windows updated wiped it out; it was stable)

igfx_win10_100.9030 (latest) (I'm using this one now).


Note that after Windows Update, I had some problems installing ifgx driver.  I saw a program "Microsoft Compatibility Telemetry" under Task Manager.  So I ended this task and the igfx then was able to be installed.  Not really sure if this step is really needed. 


Install "Intel UHD Graphics Control Panel" program on your laptop. You should be able to find this program on intel's website.


Run Intel UHD Graphics Control Panel

Click on Display

Click on "Custom Resolutions"

Select Display --> U4919dw (Make sure to do this step.  Otherwise, it defaults to the laptop screen and it won't work).

Width - 5120

Height - 1440

Refresh Rate - 60

Click on "Add"


Now, go to windows display settings.  Select the u4919dw monitor.  Select the display resolution (5120x1440). It should work now. You might have to reboot.


You might have to try a few times.  But it works for me.  Good luck.
