[Bug 1893601] Re: 4k not working
Although I can see from 'kernel-modes.txt' that the problem is originating from the kernel. So the Wayland session is unlikely to help. ** Changed in: xorg-server (Ubuntu) Status: Incomplete => Invalid ** No longer affects: xorg-server (Ubuntu) ** Changed in: linux (Ubuntu) Status: Incomplete => New ** Summary changed: - 4k not working + [i915] 4K modes are missing when connected by HDMI -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893601 Title: [i915] 4K modes are missing when connected by HDMI (but are shown in the EDID) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1893601/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The option is unfortunately a little too hidden... You need to click on your username on the login screen and then use the icon/menu in the bottom right corner of the screen before entering your password. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893601 Title: [i915] 4K modes are missing when connected by HDMI (but are shown in the EDID) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1893601/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Re: [Bug 1893601] Re: 4k not working
Hi Daniel, Thank you for your quick response. The details are here. 1. Selecting 'Ubuntu on Wayland' from the login screen. Do you now get 4K modes offered in Settings? - I don't see any Wayland option. The max resolution at Display Settings is 1080p. 2. Run: grep . /sys/class/drm/*/modes > kernel-modes.txt - Attached the file.

Yes it looks like either the kernel driver or Xorg driver is failing to expose 4K modes, which definitely should be available: EDID version: 1.3 Manufacturer: SAM Model 3988 Serial Number 0 Made in week 41 of 2018 Digital display Maximum image size: 70 cm x 39 cm Gamma: 2.20 DPMS levels: Off RGB color display First detailed timing is preferred timing Color Characteristics Red: 0.6513, 0.3398 Green: 0.2998, 0.6230 Blue: 0.1494, 0.0712 White: 0.3125, 0.3291 Established Timings I & II 720x40070.082 Hz 9:531.467 kHz 28.320 MHz (IBM) 640x48059.940 Hz 4:331.469 kHz 25.175 MHz (DMT) 640x48066.667 Hz 4:335.000 kHz 30.240 MHz (Apple) 640x48072.809 Hz 4:337.861 kHz 31.500 MHz (DMT) 640x48075.000 Hz 4:337.500 kHz 31.500 MHz (DMT) 800x60056.250 Hz 4:335.156 kHz 36.000 MHz (DMT) 800x60060.317 Hz 4:337.879 kHz 40.000 MHz (DMT) 800x60072.188 Hz 4:348.077 kHz 50.000 MHz (DMT) 800x60075.000 Hz 4:346.875 kHz 49.500 MHz (DMT) 832x62474.551 Hz 4:349.726 kHz 57.284 MHz (Apple) 1024x76860.004 Hz 4:348.363 kHz 65.000 MHz (DMT) 1024x76870.069 Hz 4:356.476 kHz 75.000 MHz (DMT) 1024x76875.029 Hz 4:360.023 kHz 78.750 MHz (DMT) 1280x1024 75.025 Hz 5:479.976 kHz 135.000 MHz (DMT) 1152x87075.062 Hz 192:145 68.681 kHz 100.000 MHz (Apple) Standard Timings 1152x86475.000 Hz 4:367.500 kHz 108.000 MHz (DMT) 1280x80059.810 Hz 16:10 49.702 kHz 83.500 MHz (DMT) 1280x72060.000 Hz 16:945.000 kHz 74.250 MHz (DMT) 1280x1024 60.020 Hz 5:463.981 kHz 108.000 MHz (DMT) 1440x90059.887 Hz 16:10 55.935 kHz 106.500 MHz (DMT) 1600x90060.000 Hz 16:960.000 kHz 108.000 MHz (DMT, RB) 1680x1050 59.954 Hz 16:10 65.290 kHz 146.250 MHz (DMT) Detailed mode: Clock 594.000 MHz, 697 mm x 392 mm 3840 4016 4104 4400 (176 88 296) 2160 2168 2178 2250 ( 8 10 72) +hsync +vsync VertFreq: 60.000 Hz, HorFreq: 135.000 kHz Display Range Limits Monitor ranges (GTF): 24-75 Hz V, 30-135 kHz H, max dotclock 600 MHz Display Product Name: U32R59x Display Product Serial Number: H1AK50 Has 1 extension block Checksum: 0x46 CTA-861 Extension Block Revision 3 Underscans PC formats by default Basic audio support Supports YCbCr 4:4:4 Supports YCbCr 4:2:2 0 native detailed modes 48 bytes of CTA data blocks Video Data Block 3840x2160 60.000 Hz 16:9 135.000 kHz 594.000 MHz (VIC 97) 720x57650.000 Hz 16:931.250 kHz 27.000 MHz (VIC 18) 720x48059.940 Hz 16:931.469 kHz 27.000 MHz (VIC 3) 1280x72050.000 Hz 16:937.500 kHz 74.250 MHz (VIC 19) 1280x72060.000 Hz 16:945.000 kHz 74.250 MHz (VIC 4) 1920x1080 24.000 Hz 16:927.000 kHz 74.250 MHz (VIC 32) 1920x1080 30.000 Hz 16:933.750 kHz 74.250 MHz (VIC 34) 1920x1080 50.000 Hz 16:956.250 kHz 148.500 MHz (VIC 31) 1920x1080 60.000 Hz 16:967.500 kHz 148.500 MHz (VIC 16) 3840x2160 30.000 Hz 16:967.500 kHz 297.000 MHz (VIC 95) 3840x2160 50.000 Hz 16:9 112.500 kHz 594.000 MHz (VIC 96) 3840x2160 24.000 Hz 16:954.000 kHz 297.000 MHz (VIC 93) 3840x2160 25.000 Hz 16:956.250 kHz 297.000 MHz (VIC 94) Audio Data Block Linear PCM, max channels 2 Supported sample rates (kHz): 48 44.1 32 Supported sample sizes (bits): 24 20 16 Speaker Allocation Data Block Speaker map: FL/FR - Front Left/Right Vendor-Specific Data Block, OUI 0x000c03 (HDMI) Source physical address 1.0.0.0 Supports_AI DC_36bit DC_30bit DC_Y444 Maximum TMDS clock: 300 MHz Extended HDMI video details: HDMI VICs: 3840x2160 30.000 Hz 16:967.500 kHz 297.000 MHz (HDMI VIC 1) 3840x2160 25.000 Hz 16:956.250 kHz 297.000 MHz (HDMI VIC 2) 3840x2160 24.000 Hz 16:954.000 kHz 297.000 MHz (HDMI VIC 3) Vendor-Specific Data Block, OUI 0xc45dd8 (HDMI Forum) Version: 1 Maximum TMDS Character Rate: 600 MHz SCDC Present Supports 12-bits/component Deep Color 4:2:0 Pixel Encoding Supports 10-bits/component Deep Color 4:2:0 Pixel Encoding Extended tag: YCbCr 4:2:0 Capability Map Data Block 3840x2160 60.000 Hz 16:9 135.000 kHz 594.000 MHz (VIC 97) 3840x2160 50.000 Hz 16:9 112.500 kHz 594.000 MHz (VIC 96) Detailed mode: Clock 148.500 MHz, 697 mm x 392 mm 1920 2008 2052 2200 ( 88 44 148) 1080 1084 1089 1125 ( 4 5 36) +hsync +vsync VertFreq: 60.000 Hz, HorFreq: 67.500 kHz Detailed mode: Clock 148.500 MHz, 697 mm x 392 mm 1920 2448 2492 2640 (528 44 148) 1080 1084 1089 1125 ( 4 5 36) +hsync +vsync
