This is because, at present, the i.MX95 Reference Manual Rev. 1.0 remains a pre-production manual. It has been confirmed by the NXP support team that the incomplete display controller portion is on purpose and that the documentation is still undergoing changes. They expect an enhanced display portion in the reference manual when the processor will be available.
Therefore, it does not mean that the capabilities of the i.MX95 display controller are any less than those of i.MX8 implementation. Instead, the present RM remains unfinished in terms of customer-facing documentation. The NXP product page currently displays the version of i.MX95 RM as Rev. 1.0 dated March 30, 2026.
