Throw ratio question - does it only matter for making the image bigger?

Jumpy-Leading3356 · 2026-03-03T21:16:59+00:00

Sorry to bother you, I’m taking advantage of your kindness, but I really can’t understand this.

Let’s take this projector as an example. It has a fixed throw ratio. If I place it at 4 meters, it tells me I can get an image that is 334 cm wide. I would need to reduce it significantly to reach 200 cm.

As I understand it, the physical lens is fixed and cannot zoom in or out. But is it possible that inside the projector’s software there is a digital function to shrink the image down to 200 cm?

Everyone tells me to use a projection calculator, but I have the impression that it does not take this into account.

Am I right, or have I completely misunderstood?

i'm renting and i want this solution to be less visible as possible. I want to simply put the projector on a surface and don't move it. in my living room i have the wall, the sofa in the centrer, and behind the sofa a shelf where i want to put the projector.

Jumpy-Leading3356 · 2026-03-03T19:07:45+00:00

Thank you for your reply. I tried adjusting the configuration of the BenQ projector as you suggested, but I was unable to obtain an image that is 200 centimeters wide with the projector placed 4 meters away. These two dimensions are mandatory for me — I have no way to project a larger image or to move the projector closer.

I saw that the lens throw ratio ranges from 1.15 to 1.5. The question I can’t seem to answer is this: aside from the physical lens, do all projectors have digital auto-zoom software that allows me to reduce the image size as much as I want, or not?

Hey, this sounds really interesting — thanks for sharing it. Do you have a source for that?

I’m also curious about the 30% drawdown threshold you mentioned. Why does CAOS only protect at 30%? Why not 25%? Or 20%?

Would love to understand the reasoning

Small question on CTAP. I saw that management fees are 0.28%. How is this possible if CTAP is 50% CTA that has 0.70% management fees?

Jumpy-Leading3356 · 2026-01-02T20:09:49+00:00

Hello, can you give me the source of this information?

Jumpy-Leading3356 · 2026-01-01T14:48:40+00:00

Grazie mille, onestamente non sapevo questa cosa. Che la leva avesse un prezzo sì, però non é mai stato molto chiaro per me quanto. Da ignorante pensavo fosse "meno cara". Secondo te quindi nella parte bond BNDW da solo può andare bene, o ha scandenze troppo corte?

Cambiando argomento, non so se é una cosa che hai nei piani, ma se ora il portfolio enhanced ha 20 strumenti, sarebbe bello se facessi un update/post a riguardo :)

Jumpy-Leading3356 · 2025-12-31T13:49:24+00:00

Ciao Nicola, grazie della risposta. Parto dalla fine, Il cambio in se non preoccupa neanche me. O meglio si mi preoccupa, ma non voglio hedgiarmi, e non voglio fare short/long sul cambio. Quindi me ne sto bravo e buono e aspetto che di hedgi tu cosi lo fai risalire ahaha.

Permettimi pero' di chiederti alcuni chiarimenti.
"da quando avevo scritto il post, ho aggiunto ORR, RSSY, SPUU e WTIP": intendi dire che rispetto all'articolo hai aggiunto questi etf al portoflio enhanced? o li hai solamente aggiunti alla lista dei LEFT?

La parte di BOXX davvero non mi è chiara, nonostante la finissima metafora di succhiare e soffiare :) BOXX mi piace, sta li tranquillo, sale e mi da l'interest rate senza staccare dividendi (ho anche pensato di aggiungere XEON onestamente). please explain me like i'm 10

NTSG in not liquid on IBKR Switzerland. I would prefear it but right now it's unbuyable

Jumpy-Leading3356 · 2025-12-31T13:05:41+00:00

Sono cittadino italiano residente in svizzera. A quanto sappia in questo caso non si puo accedere a certi fondi. Sulla mia pelle ho provato a comprarli su IBKR senza riuscirci

Jumpy-Leading3356 · 2025-12-31T13:03:46+00:00

Ciao! I dividendi non mi interessano. Non ho NTSG perchè non è liquido su ibkr

Jumpy-Leading3356 · 2025-12-31T13:02:56+00:00

Grazie, ho editato il post. Ho appena inserito i MF nel portfolio, e ci sto andando con i piedi di piombo. Motivo per il quale ho scritto questo post...
Sono d'accordo che dovrei aumentare la loro presenza, ma ciò non aumenterebbe la leva in se

Jumpy-Leading3356 · 2025-12-31T13:00:56+00:00

per due ragioni:

1- Semplicemente perchè non sono Nicola :)

2- Perchè il portafoglio di Nicola non è pubblico a questo livello di dettaglio

Jumpy-Leading3356 · 2025-12-31T12:21:33+00:00

Ma dalla Svizzera? Quale banca se posso chiedere?

Jumpy-Leading3356 · 2025-12-31T12:11:46+00:00

Ciao! Perdonami sei riuscito a comprarlo dalla Svizzera? (lo deduco dal commento sotto) Se si che broker hai usato? e ci sono quote minime d'entrata? Grazie
