Latitude 5440 Intel Graphics Command center No maintain display scaling option
Hi, I have a fleet of Latitude 5440 laptops for the school site I work at.
Intel graphics command center no longer has a maintain display scaling option for our tv to get the active resolution to 1080p
We previously coming off of Lattitude 5310
We have this topology.
We have various 75-inch Sony tv 800 or 850 series from the last 7-8 years all 4k tv.
From the tv, we have an HDMI that goes to a wall port that connects to an ELMO doc cam tt12-ID.
From the ELMO doc cam tt12-ID, we have a passthrough HDMI that goes to the Wd19TB docking station.
We then have a C2722DE plugged via USB-C to the thunderbolt port on the docking station.
This is the setup we used for 4 years and with the option to change the TV to the maintain display scaling option to make this all work in the intel graphics command center which allows us to change the active desktop resolution to 1920x1080 from the 4k active desktop resolution.
Without being able to change to maintain display scaling to get the active desktop resolution to change there is some weird artifacting happening and distroted stuff happening.
The new 5440 latitude doesn't have this option anymore only lets us choose to maintain the aspect ratio or the custom option.
Is there something we can do to fix this or get a driver updated from Intel to fix this it's making things not work properly in the classrooms.
If you need more details please let me know. I have tested this in multiple classrooms which all have the same topology and even slightly different year models of Sony TV.

I believe I might have partially solved the problem, but it's not completely fixed yet. Let me explain what happened:
When I connected my laptop to the setup, it automatically mirrored the laptop and the TV at a resolution of 1920x1080. However, I noticed that the TV's refresh rate was set to 30Hz in the advanced display settings. This caused some issues, but I managed to fix it by changing the refresh rate to 60Hz. Now, the active desktop resolution matches the desktop's resolution, and everything appears correctly, including the TV at 1080p.
To further test the setup, I decided to use the extended mode, enabling all three displays. This allowed me to set the TV's resolution to 1920x1080 at 60Hz, and everything worked fine.
One interesting thing I observed is that when the TV's refresh rate was set to 30Hz, I could use the Intel graphics command center to select "maintain display scaling," and this made 30Hz work properly. This is the only time that the "maintain display scaling" will show up as an option.
I am still concerned about why the TV display in the advanced display setting is always defaulting to 30hz when connecting to a new tv room that the laptop has not connected to before. It would be a huge thing to get this to always go 60zh when they connected to a new room then we would have a working display all the time when people have to move rooms or sub in another classroom.
Another thing to note is that the laptop is direct to the wall HDMI port with no docking station defaults to either 1920x1080 at 30Hz and has the same scaling issues or in some rooms defaults to 4k 30hz and we have either no picture or a distorted picture.
Considering all of this, to make my rooms fully functional, I'm leaning towards buying scalars that will force a resolution of 1920x1080 at 60Hz. This process may take some time, so until then, I'll need to rely on the current workaround of force changing the refresh rate to 60hz but would really think something can be done to make this Tv force 1920x1080 at 60hz by default that could help me further till we can get scalers going in the classroom.
Please let me know your suggestions
