What is the maximum display resolution Pi can support?

[mahesh1988]

I'am using pi3 and try to connect to the ULTRA STRETCH (3840 x 600) display but Pi is not responding with the actual resolution.
tvservice recognise only upto 1920x1080 .

Specs:
pi version : pi3
OS version : raspbian wheezy
Display : ULTRA STRETCH (3840 x 600 ) http://www.lg.com/us/business/commercia ... /lg-86BH5C

Is there any Maximum resolution for Pi could support?

Thanks in advance for the support

Thanks in advance for the support

1) You shouldn't need to run the tvservice command with sudo privileges** ('though that's probably a "red herring")
2) AIUI, the tvservice command reports (extracted) edid info. sent back to the Pi from the monitor/display/TV
3) I'm intrigued that CEA modes dominate and no preferred or native modes are being reported** (check that there aren't any unwanted settings in config.txt that are confusing matters).
4) Are you using a direct HDMI (or HDMI-to-DVI) connection (and not, say, via an HDMI-switch box or active HDMI-to-VGA converter)?

1920x1080 @60fps is the maximum supported by default. There is a thread around about supporting higher resolutions at lower frame rates. You're likely to need custom timings for such a weird resolution anyway.

@FTrevorGowen IIRC the reported edid list is already filtered based on supported modes. The native mode is going to be unsupported.

Thanks for the clarification - I suspected something "sensible" like that .

Now I'm not on a phone it's easy to find that other thread. viewtopic.php?f=38&t=79330
And viewtopic.php?f=29&t=24679 is the thread for custom HDMI modes.

Sorry, for the late replay.

@FTrevorGowen,
Thanks for the replay,

[ you are right, I don't need to use sudo for tvservice. actually I'am working with other things and type sudo for tvservice too. ]

Here am using direct HDMI connection.

Finally, I got some solutions for getting in 3840x600 resolution from the another thread pointed by @6by9.

I used the below lines in config.txt

hdmi_group=2
hdmi_mode=87
hdmi_cvt 3840 2160 24
max_framebuffer_width=3840
max_framebuffer_height=2160
hdmi_pixel_freq_limit=400000000

But X screen not taking to the full screen, working only in the middle of the screen. ( I'am running UZBL Browser )

Thanks again,

I would suggest to use a full custom hdmi Timing line and then adjust your framebuffer to the 'correct Display position'.
Since your Timing will - most likely be - for Standard UDH Display (don't know how LG manufactureed that Panel, but could simply be cutted form larger Panel).
You should ask for the spec of the LCD module and then you'll know what Timing Needs to be.
