    Not 1. D8=q ?? because of qh1+ kg4 and qh5 mate. So instead 1qf8+! Kxf8 2. D8=Q + Kf7 3. Qxd4 Qh1+ 4. Kg4 Qh5+ 5. kf4 Qf5+ 6.Ke3 and white escapes any meaningful checks.

    Queening the d-pawn at once loses, because Black threatens
    1. … Qh1+
    2. Kg4 Qh5#;
    In addition to that, the white queen does not have a check from a safe square at the moment.
    But … what if the pawn could be promoted with a check? Ahhh….!
    1. Qf8+!! Kxf8 forced
    2. d8=Q+ Kf7
    2. … Kg7
    3. Qe7+ and now
    … Kg8 4.Nf6+ Kh8 5.Qxh7#
    … Kh8 4.Qf8#
    … Kh6 4.Qf8+ Bg7 5.Qf4+ Kh5 6.g4#/Qh4#
    3. Ng5+ Kg7 forced
    4. Qe7+ Kh6
    4. … Kg8 5.Qf7+ Kh8 6. Qxh7#
    4. … Kh8 5. Qxh7#
    5. Qf8+ Kxg5
    5. … Bg7 6.Nf7+ Kh5 7.g4#
    5. … Kh5 6. g4+ Kxg5 7.f4#
    6. Qf4+ Kh5
    7. g4#

    Well, the “obvious” move of 1.d8(Q) is going to lose brutally to Qh1+ followed by Qh5#. One solution occurred to me within 5 seconds:

    1. Qf8! Kf8
    2. d8Q

    With check, and a double attack on the king and undefended bishop at d4.

    The move Qf8 also accomplishes something else- it opens the f4 square for the king thus eliminating any mate and perpetual check opportunities for black after a possible Qh1+. However, I am not sure that even matters since white is going to capture at d4 with check anyway and mate black quickly. For example:

    2. ……Kf7 (Kg7 3.Qd4+)
    3. Ng5! Kg7 (only legal move)
    4. Qd4 with check, and mate to follow.
