Hi NicoD ! Thanks for your suggestion. Tried that, but it fails to apply the new mode: screen blanks for a couple of seconds then xrandr spits an error "configure crtc 0 failed" : ~$ cvt 2560 1440 60 # 2560x1440 59.96 Hz (CVT 3.69M9) hsync: 89.52 kHz; pclk: 312.25 MHz Modeline "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync ~$ xrandr --newmode "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync ~$ xrandr --addmode HDMI-1 "2560x1440_60.00" ~$ xrandr Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 3840 x 2160 HDMI-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 527mm x 296mm 1920x1200 59.95 1920x1080 60.00* 60.00 50.00 59.94 24.00 23.98 1920x1080i 60.00 60.00 50.00 59.94 1600x1200 60.00 1680x1050 59.88 1280x1024 75.02 60.02 1280x800 59.91 1152x864 75.00 1280x720 60.00 60.00 50.00 59.94 1024x768 75.03 60.00 800x600 75.00 60.32 720x576 50.00 50.00 720x480 59.94 59.94 59.94 640x480 75.00 2560x1440_60.00 59.96 ~$ xrandr --output HDMI-1 --mode 2560x1440_60.00 xrandr: Configure crtc 0 failed ~$ Any ideas ? [edit 2020/16] tried with many other refresh rates and even copying the modeline data from my desktop while hooked to the same display: same error. Starting to wonder whether this a95x's s905x is really capable of outputing any resolution beyond 1080p.... ??

Hi, I've just setup armbian to run from sdcard on a NexBox a95x-B7N (s905x, 2G Ram, 8G Rom). Running a minimal install for desktop (server image + Xorg, openbox and tools I use installed manually). My issue is the X server runs at 1080p while hooked via HDMI to a 1440p@60 display (Dell P2416D). xrandr does not detect any higher resolution than 1080p, and the edid doesn't show any either: ~$ edid-decode /sys/devices/platform/soc/d0100000.vpu/drm/card0/card0-HDMI-A-1/edid EDID version: 1.3 Manufacturer: DEL Model a0c3 Serial Number 808797781 Made in week 43 of 2015 Digital display Maximum image size: 53 cm x 30 cm Gamma: 2.20 DPMS levels: Standby Suspend Off RGB color display First detailed timing is preferred timing Display x,y Chromaticity: Red: 0.6533, 0.3310 Green: 0.2958, 0.6210 Blue: 0.1484, 0.0517 White: 0.3134, 0.3291 Established timings supported: 720x400@70Hz 9:5 HorFreq: 31469 Hz Clock: 28.320 MHz 640x480@60Hz 4:3 HorFreq: 31469 Hz Clock: 25.175 MHz 640x480@75Hz 4:3 HorFreq: 37500 Hz Clock: 31.500 MHz 800x600@60Hz 4:3 HorFreq: 37900 Hz Clock: 40.000 MHz 800x600@75Hz 4:3 HorFreq: 46900 Hz Clock: 49.500 MHz 1024x768@60Hz 4:3 HorFreq: 48400 Hz Clock: 65.000 MHz 1024x768@75Hz 4:3 HorFreq: 60000 Hz Clock: 78.750 MHz 1280x1024@75Hz 5:4 HorFreq: 80000 Hz Clock: 135.000 MHz Standard timings supported: 1280x800@60Hz 16:10 1680x1050@60Hz 16:10 HorFreq: 64700 Hz Clock: 119.000 MHz 1920x1200@60Hz 16:10 HorFreq: 74000 Hz Clock: 154.000 MHz 1152x864@75Hz 4:3 HorFreq: 67500 Hz Clock: 108.000 MHz 1600x1200@60Hz 4:3 HorFreq: 75000 Hz Clock: 162.000 MHz 1280x1024@60Hz 5:4 HorFreq: 64000 Hz Clock: 108.000 MHz 1920x1080@60Hz 16:9 Detailed mode: Clock 241.500 MHz, 527 mm x 296 mm 2560 2608 2640 2720 hborder 0 1440 1443 1448 1481 vborder 0 +hsync -vsync VertFreq: 59 Hz, HorFreq: 88786 Hz Serial number: 6RC2C5AJ05FU Monitor name: DELL P2416D Monitor ranges (GTF): 49-86Hz V, 29-113kHz H, max dotclock 280MHz Has 1 extension blocks Checksum: 0x1d (valid) CTA extension block Extension version: 3 31 bytes of CTA data Video data block VIC 16 1920x1080@60Hz 16:9 (native) HorFreq: 67500 Hz Clock: 148.500 MHz VIC 5 1920x1080i@60Hz 16:9 HorFreq: 33750 Hz Clock: 74.250 MHz VIC 4 1280x720@60Hz 16:9 HorFreq: 45000 Hz Clock: 74.250 MHz VIC 3 720x480@60Hz 16:9 HorFreq: 31469 Hz Clock: 27.000 MHz VIC 2 720x480@60Hz 4:3 HorFreq: 31469 Hz Clock: 27.000 MHz VIC 7 1440x480i@60Hz 16:9 HorFreq: 15734 Hz Clock: 27.000 MHz VIC 22 1440x576i@50Hz 16:9 HorFreq: 15625 Hz Clock: 27.000 MHz VIC 1 640x480@60Hz 4:3 HorFreq: 31469 Hz Clock: 25.175 MHz VIC 6 1440x480i@60Hz 4:3 HorFreq: 15734 Hz Clock: 27.000 MHz VIC 17 720x576@50Hz 4:3 HorFreq: 31250 Hz Clock: 27.000 MHz VIC 18 720x576@50Hz 16:9 HorFreq: 31250 Hz Clock: 27.000 MHz VIC 21 1440x576i@50Hz 4:3 HorFreq: 15625 Hz Clock: 27.000 MHz VIC 19 1280x720@50Hz 16:9 HorFreq: 37500 Hz Clock: 74.250 MHz VIC 20 1920x1080i@50Hz 16:9 HorFreq: 28125 Hz Clock: 74.250 MHz VIC 31 1920x1080@50Hz 16:9 HorFreq: 56250 Hz Clock: 148.500 MHz VIC 32 1920x1080@24Hz 16:9 HorFreq: 27000 Hz Clock: 74.250 MHz Audio data block Linear PCM, max channels 2 Supported sample rates (kHz): 48 44.1 32 Supported sample sizes (bits): 24 20 16 Vendor-specific data block, OUI 000c03 (HDMI) Source physical address 1.0.0.0 Speaker allocation data block Speaker map: FL/FR - Front Left/Right Underscans PC formats by default Basic audio support Supports YCbCr 4:4:4 Supports YCbCr 4:2:2 1 native detailed modes Detailed mode: Clock 148.500 MHz, 527 mm x 296 mm 1920 2008 2052 2200 hborder 0 1080 1084 1089 1125 vborder 0 +hsync +vsync VertFreq: 60 Hz, HorFreq: 67500 Hz Detailed mode: Clock 74.250 MHz, 527 mm x 296 mm 1920 2008 2052 2200 hborder 0 540 542 547 562 vborder 0 +hsync +vsync interlaced VertFreq: 60 Hz, HorFreq: 33750 Hz Detailed mode: Clock 74.250 MHz, 527 mm x 296 mm 1280 1390 1430 1650 hborder 0 720 725 730 750 vborder 0 +hsync +vsync VertFreq: 60 Hz, HorFreq: 45000 Hz Detailed mode: Clock 27.000 MHz, 527 mm x 296 mm 720 736 798 858 hborder 0 480 489 495 525 vborder 0 -hsync -vsync VertFreq: 59 Hz, HorFreq: 31468 Hz Detailed mode: Clock 197.000 MHz, 527 mm x 296 mm 2048 2400 2616 2752 hborder 0 1152 1187 1192 1195 vborder 0 -hsync +vsync VertFreq: 59 Hz, HorFreq: 71584 Hz Checksum: 0x4d (valid) Yet, I know for a fact the monitor works perfectly at 1440p over HDMI (linux desktop connected to it works at proper resolution).
