The short answer
This is not a question of which is better. Your flat and your viewing hours decide it. Daytime viewing, children watching, a set left on in the background — television. Evening film-watching with the curtains drawn, a screen above 100 inches, and somewhere to put an ultra-short-throw unit — projector. And at the 100-inch 4K level the two cost about the same; the real difference is ambient light and placement, not price.
Dividing line one: when do you watch?
A projector works by reflected light, so the more ambient light in the room, the paler the picture. That is physics, not a model-specific weakness. So the first question is not the budget but "when is it mostly on?"
Learn to read ANSI lumens — a standardised measurement. If a projector quotes only "lumens" without stating ANSI, you have no basis for comparing it with anything else. In practical terms:
- 200 to 450 ANSI — needs near-total darkness. These are camping, bedroom, small-image, occasional-use machines.
- 800 to 1,200 ANSI — with curtains drawn in the evening and lights off or dimmed, 80 to 100 inches works comfortably. This is the realistic entry point for a Hong Kong home.
- 1,600 to 2,400 ANSI — copes with some ambient light in the evening, and just about manages daytime behind heavy curtains.
But to be plain about it: even 2,400 ANSI will not beat a television in daylight. If your set is mostly on during the day, with children watching cartoons or running as background, the answer is a television — no further analysis needed.
Dividing line two: will it physically fit a Hong Kong flat?
This is what people most often regret afterwards. Here is arithmetic you can check:
A 100-inch 16:9 image is 2.214 metres wide. Specification sheets quote a throw ratio, and throw distance = throw ratio × image width.
| Projection type | Distance needed for 100 inches |
|---|---|
| Standard throw (ratio around 1.2:1) | About 2.66 metres — the unit sits behind the sofa or on the ceiling, and few Hong Kong living rooms have that much clear depth |
| Ultra-short-throw (ratio 0.18:1 to 0.21:1) | Officially 24.8 centimetres for a 100-inch image — it sits on the TV cabinet against the wall |
So the conclusion is unambiguous: a projector in a small Hong Kong flat means an ultra-short-throw projector. A standard-throw unit in a 400 sq ft flat either goes on the ceiling or sits behind everyone's heads — both are a nuisance.
One more thing: the wall you project onto needs to be flat, pale and ideally free of texture or hangings. Plenty of Hong Kong flats have false walls, pictures, or uneven plaster — in which case budget the space and money for a screen.
Dividing line three: how big, and for how much
Using real prices from our own shelves makes this concrete:
| What you want | Television route | Projector route |
|---|---|---|
| 100 inches, native 4K, genuinely good | 100-inch Neo QLED, about $35,980 | UST 4K laser at 2,400 ANSI, about $31,499 — near enough the same money, with ambient light and placement as the real difference |
| A big screen, spending less | 98-inch Crystal UHD, about $22,800 | UST 1080p laser at 1,000 ANSI, about $6,780 — two thirds cheaper, at the cost of native 1080p and a need to control light |
| Under $3,000 | A 55-inch 4K set, usable at any hour, all day | An 800 ANSI 1080p unit for 100 inches in a dark room at night — a genuinely different thing, not a substitute |
The pattern is worth stating outright: a projector's real advantage is not being cheap, it is being far cheaper at the same screen size — provided you will control the light. At the top of the range, in 4K with high brightness, it costs about what a large television costs.
Other practical differences worth pricing in
- Broadcast reception. A projector has no television tuner, so an aerial is not an option — it needs a set-top box, streaming box or pay-TV box. For a television, check the model's specification sheet.
- Sound. Built-in projector audio has improved (some models carry dual 15W JBL-certified drivers with Dolby processing), but a standard-throw unit sits behind you, so the sound arrives from behind too. Serious audio still means a soundbar. An ultra-short-throw unit, sitting at the front, avoids that problem.
- Noise. Projectors have cooling fans — quiet models run around 27 to 28 decibels. A television makes none. In a small flat at night you will hear the difference.
- Gaming. High-end projectors can do it — some are officially rated at 4.2 to 8 milliseconds of lag with 120Hz support. Do not expect it from budget models, which usually do not publish a lag figure at all.
- Light source life. Current laser and LED projectors have no lamp to replace; some are officially rated at 20,000 hours. At four hours a day that is well over a decade.
Which one is for you
Buy a television if: you watch during the day, there are children in the house, it will be left on in the background, you want to connect an aerial, your living room has plenty of windows and you would rather not draw curtains daily, or the size you actually want is 65 to 85 inches rather than 100-plus.
Buy a projector if: films come first, viewing is mostly at night, you want 100 inches or more, you have a flat pale wall (or will fit a screen), and you choose ultra-short-throw so it physically fits.
Plenty of people buy both — a television in the living room for daily use and the children, a projector in a bedroom or media room for films. That combination is more common in Hong Kong than you might expect.

Frequently asked questions
Will a projector fit in a small Hong Kong flat?
Yes, if it is ultra-short-throw. The arithmetic is simple: a 100-inch 16:9 image is 2.214 metres wide, and a standard-throw projector with a 1.2:1 throw ratio therefore needs 2.66 metres of distance — more clear depth than most Hong Kong living rooms have, leaving the ceiling or behind-the-sofa as the only options. Ultra-short-throw units have throw ratios of 0.18:1 to 0.21:1 and are officially documented at 24.8 centimetres for a 100-inch image, so they sit on the TV cabinet against the wall.
Can you use a projector during the day?
You can, but it will not look good. A projector relies on reflected light, so the more ambient light there is, the paler the image — a physical limit, not a model weakness. Machines in the 200 to 450 ANSI lumen range need near-darkness; 800 to 1,200 ANSI is fine at night with curtains drawn; 1,600 to 2,400 ANSI copes with some ambient light. But even 2,400 ANSI will not beat a television in daylight, so daytime viewing means a television.
Is a projector always cheaper than a TV?
Much cheaper at the same screen size, but not cheaper outright. In real prices: a 98-inch television is about $22,800 while a 1080p ultra-short-throw laser projector is about $6,780 — two thirds less. But at 100 inches in native 4K with high brightness, the television is about $35,980 and the UST 4K laser projector about $31,499 — near enough the same. A projector's advantage is size per dollar, not absolute price.
Can a projector receive Hong Kong free-to-air channels?
No — a projector has no television tuner, so an aerial cannot be connected. Watching broadcast channels requires a set-top box, streaming box or pay-TV operator's box connected over HDMI. This applies to every projector regardless of price.
Do projectors need frequent lamp replacement?
Not the current laser and LED models — there is no lamp to replace, and some are officially rated at 20,000 hours of light-source life, which at four hours a day is well over a decade. What to consider instead is cooling-fan noise (quiet models run around 27 to 28 decibels) and keeping the unit free of dust.
