topic Galaxy Flex Book Alpha - HDMI port limitations & USB-C questions in Computers https://us.community.samsung.com/t5/Computers/Galaxy-Flex-Book-Alpha-HDMI-port-limitations-amp-USB-C-questions/m-p/1391308#M4362 I recenlty purchased a Galaxy Book Flex α 13.3” ( NP730QCJ-K02US  -- i7/12gb/512gb), and I've been surprised and dissapointed by the lack of a proper owners manual with complete specifications.  There's a "user's guide" which contains generic information about the use of the entire Galaxy Book line (13.3", 15", etc) and the specifications on the web are missing a lot of important details.   I've been trying to get support for 1440p@60Hz over HDMI (which should work by the HDMI spec) but doesn't seem supported by the hardware.  Installing the Intel driver allows the entry of additional resolutions, but it seems the HDMI port itself is limited. Any resolution/refresh rate higher than 2560x1440@40Hz produces an "exceeds maximum bandwidth" message.  I've tried three different HDMI cables, including 2 that are rated for 4K.   Given that there are plenty of 4K HDMI devices, it seems the HDMI port on this device does not support HDMI 1.4. I've considered buying a USB-C display adapter, but without a list of supported alternate modes on the USB-C port, I don't know what version of display port is supported. Does a comprehensive specifications document exist for this laptop?  The brief list of specifications on the website is really insufficient. EDIT: I have applied the November 2020 BIOS update and <A href="mailto:1440p@60Hz" target="_blank" rel="noopener">1440p@60Hz</A> over HDMI now works in Windows 10.  A comprehensive, detailed specifications document  would still be appreciated if anyone has one to share.
