look for USB c extension cables that support video. they are often described with different terms on amazon. I have picked up several from Amazon that work. bought this one recently, but I have not tried it yet. AINOPE USB C Extension Cable... https://www.amazon.com/dp/B09FDWG61C the description images even mention Steamdeck. I have several others I use with my deck and portable monitors. Be sure to tag/label the cables.. it sucks when you have several USB C extension cables and only some support video. You suddenly wonder why your new setup you just moved is not working, and it's because you grabbed the wrong cable.
