Boot blocks should be unrelated to this, but boot method (UEFI or BIOS) may play a role (that is not fully analyzed). We need more details, like full dmesg. Does the kernel probe the correct display connection? There are a few i915 PRs open that are caused by the wrong connector being used or the proper connector not responding, so the display capabilities can not be read, but there may be other reasons why the kernel can not read the EDID data.
