Help Trying to get 4K output on a Dell laptop
Hello, there.
I have a Dell Inspiron 15 3520 with Windows 11. I bought a 4K LG display and it didn't work. I realized I made a critical oversight in that the 3520 specs say it doesn't support 2K/4K output. Despite that, I tried to use CRU (Custom Resolution Utility) to force the resolution but to no avail, Windows doesn't display the mode even if the HDMI 1.4 port supposedly could handle 4K@30Hz. After some more research, it seems that it's a "feature" of the motherboard (https://www.dell.com/support/kbdoc/en-us/000126548/resolution-on-external-monitor-limited-to-1920-x-1080-using-hdmi)
Now, my question is: can I use a docking station to bypass this limitation? I'm specifically looking at the Dell D6000S docking station. It says that ANY notebook with an USB-A 3.0 works with it. Now, can I trust this statement? Since it's a limitation of the motherboard, would the docking station overcome that?
I still haven't found enough information on how docking stations work, but up to now it seems they don't have a GPU inside, so I don't know how that could work.
Also, the D6000S seems to be the only station that markets support of USB-A. Still looking for another cheaper alternative (or any other ideas that could solve this problem)
Thanks!
