Hi Adam, Got it. If the panel isn't affected by the 20ms sleep time, I'd prefer to keep it since 100ms is a pretty big increase. > > I have been able to re-use the gip sequence from the kd50t048a panel > used in the Hardkernel Odroid > Go Super as I have been led to believe it is the same elida panel, > unfortunately the same modes > used by that device do not work for the Odroid Go Ultra and so its still > necessary to have the > patchset, Got it. FWIW, I do see the Odroid Go Ultra being described as having the kd50t048a panel [1] [2]. Looking forward to seeing the v3 changes.
