The myWall HP 1D is for monitors from 37" - 70" (94 - 178 cm) and is Vesa compatible with 200x200 - 600x400.
So your monitor is too small and also not compatible. The bracket is really very big, I have a 55" TV on it and even this looks quite small in relation to the bracket.
For your needs you would need the "HP 1 C" but even this would still be quite large.

I think the quality of the holder is very good and I can recommend it.
