Hello everyone,
I’m seeking assistance with a display scaling issue on my Lubuntu 24.04.2 installation.
My setup:
Laptop: DELL Latitude 7285
-
Processor: Intel® Core™ i7 i7-7Y75
-
Type: Hybrid (2-in-1)
-
Screen Size: 31.2 cm (12.3") Touchscreen
-
RAM: 16 GB LPDDR3-SDRAM
-
Storage: 512 GB SSD
-
Wireless: Wi-Fi 5 (802.11ac)
-
External Monitor: Lenovo L28u-30 (4K resolution capable)
-
Operating System: Lubuntu 24.04.2
The Problem:
I’m experiencing difficulty achieving proper scaling when using my Lenovo L28u-30 4K monitor in a dual-monitor setup with my Dell Latitude 7285.
Currently, the maximum resolution I can get on the Lenovo L28u-30 is 2K (2560x1440), which seems to be mirroring the resolution of my Dell Latitude 7285’s internal display. Even if I turn off the laptop’s screen, the external monitor remains capped at 2K.
When I attempt to set the external monitor to its native 4K resolution (3840x2160), everything on the screen becomes too small to be usable. I need a solution for proper display scaling to make the 4K resolution viable.
I recall seeing a similar discussion on the old Lubuntu discourse (https://discourse.lubuntu.me/t/help-scaling-the-desktop-on-lubuntu/4810?page=2 2), but I’m unable to access that specific thread.
Any guidance or suggestions on how to effectively scale the desktop on Lubuntu 24.04.2 for a 4K external monitor would be greatly appreciated.
Thank you in advance for your help!
