If your wall is timber-framed, then for standard doorways you don’t generally need lintels at all. Lintels are used where you’ve got a load above the opening, like brickwork or heavy structural weight, and you need to carry that load across the span. In a framed wall, the door openings are usually just boxed out with regular framing timber.

In your case, using MGP10 90 × 45 for the framing around those 1100mm and 2100mm openings will be fine. There’s no real need to go to an LVL for this application. LVLs are often used when you need larger, stronger sections to span significant distances, or where you want the consistent performance of laminated timber. But for typical door frames in a timber wall, MGP10 90 × 45 does the job perfectly well.

So, unless you’ve got something unusual going on where those openings are carrying load from above, you can stick with your MGP10 framing without worrying about LVLs.

Please let us know if you have any questions.
