Understanding where does XrandR command get its values from












-1















Using HP t530 Thin clients in the office
Using Dell U2417H monitors (display port to display port or mini display port)



Running the XrandR command from the HP OS 7.0.0 (Linux) it pulls out all the possible resolution that the monitors support



My issue is there is a bunch of resolution respecting the 16:9 aspect ratio that are missing beside 1920x1080



Dell support says it doesn't come from the Dell monitor and they don't support Linux so their monitor drivers which they don't know if it may solve the issue wouldn't work anyway



HP support says these resolutions are coming from the Dell firmware because of the obvious fact that if I plug a Viewsonic as my second monitor, I get 27 possible resolutions while the Dell only provided 14



The Dell monitor works fine under Windows 7 but Windows may as well don't care about what the monitor may provide if providing anything



Well the question is simple
using the xrandr command under Linux, where does it pool for the list of possible resolution for a monitor



If its the OS providing that list, how would I change that list for specific monitors?
If its the monitor, then I need to irritate Dell until they transfer me to their firmware department...



Thank you

    This site supports Ubuntu and official flavors. You've only mentioned a HP fork of RHEL 7.0 and Windows, neither of which are Ubuntu, nor official flavors of Ubuntu. Your question should be on SE's Unix & Linux which is not specific.

  • If I read wiki.archlinux.org/index.php/… I understand there is a way to permanently add a resolution... I'm not sure it is precise as to where it did pull out the list of resolution available for a specific monitor though "Adding undetected resolutions Due to buggy hardware or drivers, your monitor's correct resolutions may not always be detected by xrandr. For example, the EDID data block queried from the monitor may be incorrect " So the monitor does provide the list of resolution if I understand this correctly?

  • Hi guiverc, I've posted my question there too, but the guy from Dell sent me this forum....after googling what was unbundu, it felt like a variant of Linux which also runs the command XrandR.....figure it is the same command....

  • Being sent here by someone from dell does not make your question legit. You are off-topic, did you read askubuntu.com/help/on-topic. My samsung galaxy phone runs linux too, but that wouldn't make a question about it's busybox (also in Ubuntu) legit here either. Ubuntu & official flavors only are allowed here.
