First Reimbursement@PolyU!

Brief

All PolyU RPg students, irrespective of funding source, will be provided with Associated Money during the normal study period (with a reference amount of HK$20,000/year for full-time student) to support expenses for their studies and research activities.¹

I have owned an Apple Silicon MacBook Air, and expect to spend the associated money, as quoted above, for a monitor instead of buying an all-in-one computer device. As required by the department, I must provide strong justification for purchasing the proposed item.

Procedure

• Identify your need and propose a model (e.g., Monitor AOC 34P2C)
• Draft a document of justification (see mine in the attachment)
• Get consent from your chief supervisor (signed SD SRC Form 04 required ²)
• Checked by Emma
• Approved! (amount under HK$5,000, chief supervisor’s endorsement will be sufficient)
• Buy and keep all the invoices (travel expense cannot be reimbursed)
• Claim the misc. expense to Emma (signed misc. expenses claim form, undertaking declaration, invoices)
• Receive reimb. from Financial Office (FO)

Specs

• ColorSpace DCI-P3 92%
• HDMI * 2, Display Port * 1, Type-C * 1 (power delivery compatible), USB3.0 * 2
• 3440*1440, 21:9, (HiDPI is not supported on Apple Silicon Macs, yet)

TL;DR

So 3440x1440 resolution on a 34-inch panel is literally equivalent to 2K@27-in display, which macOS will see it as non-retina display and consequently disable HiDPI by default. Extra configuration is required to force retina rendering. FYI, one-key-hidpi does NOT work on Apple Silicon builds due the revision of ACPI table. For Apple Silicon Macs (Monterey beta OS), mirroring the built-in retina display with some tricks in SwitchResX would enable 5K (5120x2160) HiDPI rendering on a 3440x1440 monitor.

• QuadHD monitor with HiDPI and Mac Mini M1
