Using the Linux package monitor-edid, you can read the edid data. nvidia; EDID is information about the video modes supported by the video capture device. § This will write the The overview is to connect the GPU to the TV and use the edid tools to get the data directly from the monitor. Usually, you don't need to change this, since the default configuration is quite flexible, but sometimes, for example for strange UEFIs/BIOSes, this may be necessary (the story). Using the custom EDID method, X server will start in the EDID defined configuration. roblm is much better than I am with the EDIDs, but I seem to recall if you can get an EDID with an Nvidia driver installed, then a copy can be made and used with a different driver that may not be seeing the EDID. You could also force your settings into the fb0 by doing: echo U:1920x1200p-0 > /sys/class/graphics/fb0/mode Technically, that is what fbset is doing anyway. I have an external HDMI monitor that incorrectly reports its physical size via EDID (the monitor is 22" with a 16:10 aspect ratio, native 1680x1050 resolution, which is about 474mm x 296 mm, while the reported physical size is 160 mm x 90 mm). It was mentioned that you need to force mkinitcpio to rebuild initramfs using the new EDID firmware file but I haven't been able to find any equivalent way to do this with hdmi_force_hotplug=1 hdmi_drive=2 the lines below I tried to remove it, but same behaviour, majority of the time screen black on the hdmi1 and work perfectly on hdmi0. Using X11, adding Linux Mint Forums. 2. For example it's quite difficult to SSH to a Linux host with a GUI desktop when wayland is (increasingly) used, Kernel Mode Setting (KMS) is a method for setting display resolution and depth in the kernel space rather than user space. 2: GreyBeard: Slackware: 9: 01-13-2020 08:27 AM: Is it possible to change display resolution from 1360x768 to 1920x1080? wnderw0man: Linux - Newbie: 5: 01-28-2017 04:59 PM: Force Resolution of 4K monitor to 1920x1080 in lenovo laptop: giobaxx: Linux - Newbie: 9: 12-02-2016 02:26 PM I wanted to load customized edid so I have added it's name as "drm_kms_helper. conf, even broken hardware could be managed.

Workaround established -> partly solved, AMD is purposefully fucking up parsing EDIDs from G-SYNC monitors, fuck AMD. The Intel Graphics for Linux site describes other ways you can obtain drivers. Apparently the EDID information of the secondary is correct when it is connected alone, or I wouldn’t be able to select 1920x1200 then. Then, A recent version of a tool called edid-decode can parse EDID information, and it can read and write text and binary EDID files. The combination of your computer's ports, the graphics driver, and the EDID information coming from your monitor determine the possible resolutions. 4)SAVE THE FILE AND LOG OUT. You then set this value in the #define CRC line and compile again. However Linux being more accurate says the EDID has bad data in . Now let's activate the new EDID by reloading the video driver, simply double click restart64. I don't have any other displays so locking it to this resolution is fine. bin into my nvidia x config files with the link that Hoser Rob gave and I finally have the correct resolution on a nvidia-propietary driver.
