Raspberry PI 1920 x 1080 issues - Raspberry Pi Forums

hello everyone,

thought create quick post may assist people in future. i've purchased new raspberry pi 2 , having issues screen resolution fixed @ 1318x736 no ability change (other auto did nothing).

resolve issue did following:

run following command:

code: select all

edidparser edid

gave me lots of output looks quite overwhelming @ first there few lines needed solve problem. there many lines regarding hdmi:edid dmt mode , hdmi:edid cea mode. serching entry 1920x1080 lead me following lines.

code: select all

hdmi:edid cea mode (5) 1920x1080i @ 60 hz pixel clock 74 mhz has score of 2773832 hdmi:edid cea mode (20) 1920x1080i @ 50 hz pixel clock 74 mhz has score of 128680 hdmi:edid cea mode (31) 1920x1080p @ 50 hz pixel clock 148 mhz has score of 232360 hdmi:edid best score mode cea (16) 1920x1080p @ 60 hz pixel clock 148 mhz (score 5398248) 

above command has informed me believed best setting me use. 2 main bits of information need take away best scoring setting mode, in case cea , value within parenthesis , in case 16. take note of these they're important next step.

we're ready edit our /boot/config.txt configuration file using information we've gathered above. we're going adding values hdmi_group , hdmi_mode (you may see values within file commented out hash (#)). consistency it's best add these under following comment

# uncomment force specific hdmi mode (this force vga)

if mode cea adding following /boot/config.txt

code: select all

hdmi_group1

if mode dmt adding following /boot/config.txt

code: select all

hdmi_group2

next adding value hdmi_mode value between parenthesis. mine (16) following value added

code: select all

hdmi_mode=16

result similar below

code: select all

# uncomment force specific hdmi mode (this force vga) hdmi_group=1 hdmi_mode=16 

next step uncomment line disabling overscan.i remove hash (#) on following line @ top of page

code: select all

disable_overscan=1

commented out of lines @ bottom of page sit under comment:

# noobs auto-generated settings:

result similar this

code: select all

# additional overlays , parameters documented /boot/overlays/readme  ^m # noobs auto-generated settings:^m #hdmi_force_hotplug=1^m #config_hdmi_boost=4^m #overscan_left=24^m #overscan_right=24^m #overscan_top=16^m #overscan_bottom=16^m #disable_overscan=0^m 

reboot , should have raspberry pi displaying in 1920 x 1080 resolution!

if there's i've missed or mistakes i've made please feel free let me know. hope helps out may encountering issue!

thanks,
zarif

i've found output various options of tvservice command provides sufficient information find supported "preferred" or "native" mode - fwiw, see notes/examples here:

(without having "trawl through" output edidparser)
