t480s HDMI supported resolutions

2019-02-15, 15:37 PM

Note: Originally this post was about what i thought was a broken hdmi port, but it turned out to be due to the monitor being too old. The original problem has been fixed but i'm still a little confused, so maybe someone can shed some light on this.


So i've been using my t480s for about half a year without problems, it's a great machine. However, i came over something which suprised me a little which someone here might be able to answer. Is there limited support for older resolutions when it comes to external monitors through the HDMI?


I've been using several WQHD and 4K displays, but when i tried to connect my old 720p DVI screen through an adapter it absolutely refused to recognize it as an output. Is there some kind of limitation here that i am not aware of? This happens in both windows and linux. The monitor works just fine on a few year old mac i have laying around.

Hi Jhgjeraker! Welcome to our forums community. The minimum resolution of an HDMI is HD whcih is equivalent to 720p = 1280 x 720. We suggest you to use a different adapter or port replicator instead and check if the issue persist. Regards
