1080x1200 display

[yunkyoung]

I want to use 1080x1200 display module.

I set as below.
-----------------------------------------------
/boot/config.txt

hdmi_group=2
hdmi_mode=87

hdmi_cvt=1080 1200 90 0 0 1 1
-----------------------------------------------
But after reboot the resolution is 1080x601.
Anyone know how I can set the 1080x1200 resoltion?

Hmmm... Two things kind of jump out at me...
1. That's an unusual geometry. Could you post a link to the display?
2. By ordering the parameters the way you have, it implies that you are using it in "portrait" mode. Is that your intent?

Hi,
I bought this display.

1080x1200 resolution is The spec of display.

[lumsdot]

maybe they mean if you have two of these vr 3.8 inch displays one for each eye, then the total resolution is 1080 1200.
some sellers are selling them as a pair

[RaTTuS]

how are you connecting it to the RPI?

[yunkyoung]

This 1080x1200 module has control board with HDMI interface.
So I can Connect this module with HDMI.

[lumsdot]

do you have two or just one?

these are meant for vr displays , one for each eye

[RaTTuS]

remove any dispaly options from the config.txt file and reboot
then what does
tvservice -s
say

[lumsdot]

oculus rift uses 2 amoled 1200 x 1080 displays,
so looks like your unit should be 1200 x 1080

if they are being sold as a pair with the Hdmi driver for 100 dollars, then this could be another good use for a pi

[yunkyoung]

After remove display options from the config.txt

tvservice -s say

state 0x4002 [NTSC 4:3], 720x480 @ 60.0Hz, interlaced

The way the data in the link is written, each display would be 1090x1200. That the displays are meant for building your own VR rig explains a lot about why that resolution.

That is composite output. It suggests the HDMI hotplug signal is not asserted by monitor (it should be). Make sure monitor is powered and connected when you boot.
You can force the hotplug line with hdmi_force_hotplug=1

Hi Yunkyoung,

Were you able to find a solution to getting that screen to work? I also have the same screen and I haven't found a way yet to get the screen to work.
