AOC CQ32G1 only switches one way.

[r-franke]

So the above mentioned monitor only switches to HDMI.

If I have it connected to my desktop on DP and switch with:

ddcutil setvcp --bus=12 60 0x12

to HDMI then all is fine.

However if I try to switch back with:

ddcutil setvcp --bus=12 60 0x0f

my monitor goes black for a second and then drops back to HDMI.

From now on it won't respond to the physical buttons for switching anymore either. The behavior is the same. Blanks screen and back to HDMI if I try to switch to DP.

Only resolution now is to disconnect HDMI power cycle the monitor to get control back.

Below is the output of my interrogate command:

Setting output level verbose...
Setting maximum retries...
Forcing --stats...
Forcing --force-slave-address..
This command will take a while to run...

The following tests probe the runtime environment using multiple overlapping methods.

*** Primary Check 2: Check that /dev/i2c-* exist and writable ***

Current user: root (0)

Checking /dev/i2c-* devices...

Devices /dev/i2c-* must exist and the logged on user must have read/write permission for those devices (or at least those devices associated 
with monitors).

Typically, this access is enabled by:
  - setting the group for /dev/i2c-* to i2c
  - setting group RW permissions for /dev/i2c-*
  - making the current user a member of group i2c

Alternatively, this can be enabled by just giving everyone RW permission
The following tests probe for these conditions.

Checking for /dev/i2c-* devices...
   crw------- 1 root root 89,  0 Mar 11 09:14 /dev/i2c-0
   crw------- 1 root root 89,  1 Mar 11 09:14 /dev/i2c-1

   crw------- 1 root root 89,  9 Mar 11 09:14 /dev/i2c-9

Current user (root) has RW access to all /dev/i2c-* devices.

Checking for group i2c...
   Group i2c exists
   Current user is root, membership in group i2c not needed

Looking for udev rules files that reference i2c:

      /lib/udev/rules.d/60-sensor.rules:SUBSYSTEM=="iio", KERNEL=="iio*", SUBSYSTEMS=="usb|i2c|platform", \
   Checking rules directory /run/udev/rules.d:

Your description of the problem doesn't indicate what kind of system is connected to the HDMI port of the monitor. It may be running Linux, Windows, or something else. Apparently you are trying to switch to issue both ddcutil setvcp x60 commands from the DVI connected computer. There are several things to be aware of.

1) Some monitors will accept DDC commands on any connectors, some will only respond on the currently active input. In the latter case, you need to issue the command to switch inputs from the computer on the currently selected input. e.g. If the second system is Windows, use a program like ClickMonitorDDC.

2) A monitor can deviate from the MCCS specification as to the meaning of Non-Continuous feature values. See for example the descriptions of the Monoprice Dark Matter 40776 or the Samsung U32H750 display in Notes on Specific Monitors. Since getvcp 60 in the interrogate output reports x0f, the specified value for DisplayPort 1, and you are able to switch to the HDMI display using setvcp 60 x12, that does not appear to an issue here, but I mention it for completeness.

3) As to the lockup, I've seen reports of unexpected behaviour on feature x60 for recent monitors, particularly those with a Pcture-By-Picture facility, which feature x60 was not designed to handle. All I can say is "If it hurts, don't do it."

When submitting anything other than brief snippets, please use a separate file of some sort, e.g. as an attachment, a gist, pastebin. Do not inline them it in the message. It makes an issue thread very difficult to follow.

Good luck.
