Should I buy a projector ?

Question

I spend about 2 hours a day behind my computer desktop doing Internet search . I use either CRT, or LCD monitor.
I am 53 years of age and I find that my eyesight is getting
worse. I blame it on the computer monitors becauthey release too much radiation.

Should I buy an Overhead - Desk - Projector or a Digital Projector? Is it practical to use a projector on my P.C for Internet research? Are they easy to read? Do they emmit too much radiation?

Answer 1

Your eyesight is getting worse because you are getting old. See below for more details.


If you get a projector then you will need to place it somewhere where you can project a reasonable sized image onto a screen you can see. If anything gets between the projector and the screen it will cast a shadow.

Most projectors are either 800 by 600 or 1024 by 768. This is much lower resolution than anything but the smallest LCD screens. This is going to make the same size text harder to read as it is going to have less pixels available for font smoothing etc.


On monitor radiation:

It is just about possible to get a CRT to emit X-rays. to do this the high voltage in the CRT has to increase by about 30% to 50% over the normal value. Every CRT has a circuit that stops this from happening. It used to be that at least one monitor every day from each production line would have to have this circuit tested under DHHS rules. The DHHS drop this requirement because these circuits were so effective they did not need to be tested.

Both LCDS and CRTs produce EMI - radio waves. So does your TV, you computer, your printer. The FCC regulates these and most monitors pass the more stringent FCC class B requirements. If you have a cell phone, or someone within 30 feet of you has a cell phone you are getting more EM radiation form that cell phone than from your monitor.


Both LCDs and CRTs do produce lots of radiation in the 400 to 700 nm range. However that is because they are designed to do so as this is the range of wavelength for visible light.

Answer 2

LCDs give off pretty much no EM radiation. CRTs definitely do. But there is NO evidence that radiation from computer monitors cause eye damage.
I would advise against a projector for computer use. Not because of radiation, but because it will be very difficult to read text on a projector. What you should get is a high quality , large LCD screen (from Dell, Apple, Samsung, Viewsonic) and make the font big enough that you can read it comfortably. If you could afford to buy a good projector then you can afford to buy a large screen. I recommend the Dell WFP2407.
Just a warning: most video cards can drive a 24" LCD, but only the high end new video cards can drive a 30" LCD.



If you use internet explorer there is an option to make the fonts larger.

Answer 3

Hmm.. your room may be a sprint to small for a projector plus you pick an exceptionally dark room to absolutely get excitement from it. and you in all threat pick a demonstrate or a white delicate wall. Projectors appear like a difficulty. An lcd is ultimate. whether you may desire to purchase a projector, a minimum of an ok one, their like over 500 money

Answer 4

You can improve your eyesight by simply learning, naturally and practicing the correct way to see for a few small minutes a day.
You can check this method based on a scientific researches :

if glasses are worn continuously over time the poor vision will generally become worse. Essentially what glasses do is lock the eyes into their refractive state and in order to see through your lenses you have to maintain the poor vision that the lenses are designed to correct.
"Restore my vision” program you'll be taken by the hand, it shows you how to improve your vision naturally, permanent and complete solution.
Even the American Optometric Association has been forced to admit these things!
I'm sure that you will not regret your decision

Answer 5

Buying one is your own personal decision. A good quality one will cost a whole lot. And if the bulb burns out, its really expensive as well.


You could always buy a bigger monitor, or change the resolution on your current monitor.
Right click on the desktop, click properties, settings, and on the bottom left you will see a slider for "screen resolution". Move it to hte left to something like 1024x768 or 800x600

Answer 6

buy a digital projecter it is the best .
