Questions about this item
How loud or hot does the Core Ultra 7 255U get when the 17.3" laptop runs all day on the 45 W supply?
The 12-core, 14-thread Ultra 7 255U is rated for a 45 W power adapter, so sustained loads stay within that thermal envelope; fan noise rises under heavy work but remains typical for a thin 17.3" chassis.
Which peripherals must I already own to use the two USB-C 3.1 and two USB-A 3.0 ports on this OmniBook 3?
The laptop provides 2× USB-C 3.1 and 2× USB-A 3.0 plus HDMI 2.1 and a combo audio jack; you only need cables or hubs that match those standards — no proprietary dock is required.
Will my older 1080p monitor work over the HDMI 2.1 port alongside the built-in 1920×1080 IPS panel?
Yes — HDMI 2.1 is fully backward compatible, so a legacy 1080p display will run at its native resolution while the internal 17.3" FHD IPS screen stays active.
