    I’m considering replacing my PC monitor (Viewsonic VE902M 19" TFT 23ms 800:1 (1280x1024) Monitor) with DLP projector.

    Please, give me your advice and suggestions on the following matters:

    1. Is this a viable solution at all?
    Do you know any examples of similar replacement?

    2. What are the minimum entry level technical specifications for a budget projector to be able to show clearly EXCEL and WORD files?

    3. Any suitable makes/models?


    This is what I found, but I’m not sure if SVGA is enough for crystal view of EXCEL files.

    4. Could this option be more healthy for the eyes?

    I’m considering such replacement mainly due to eye problems. I use computer for at least 6h per day in my work and about 2h in home (but often between 10 and 12 per day). I had to get my first glasses couple of months ago and these are helpful, but after 2-3 hours I feel eye strain. Anyone with similar problem could share his approach for dealing with it.

    Any comments would be highly appreciated as I am trying to solve a health issue here. :lease:

    with ref your pc monitor, the pj will only display 800X600 so will scale down pc input, you may have probs displaying some fonts. I myself found that after 4 to 5 hours at the pc, it began to strain my vision. I found altering text size and icon size in the accessibilty option on XP useful. also changed the appearance of windows. ie alter screen colout from the bright white to aqua marine a sort of very light green it is very effective and I no longer get eye strain.
    right click desktop from menu select properties, select appearance tab. it will show your current chioce, plus all others available, just experiment and see.

    I wouldn't go with a PJ for this kind of use. Especially not a DLP.

    I have been working with computers for 15 years now and a good quality LCD is my prefrered display, I get far less eye strain with this then I did with CRTs, the Viewsonic should be fine.

    What kind of environment do you work in? Strip lights can give this effect as they flicker (in theory so fast it just looks like constant light but they can cause eye strain), they need to be shielded by diffusors.

    You need to ensure you're not constantly looking at the screen, a window you can look out off is good (it's important to change the focal distance of your eye).

    I also find that I get this more if it is warm.

    If you are getting this all the time you need to visit an optitian and explain it to them, you may need special glasses just for display equipment, or it may simply not be safe for you to use display equipment for any length of time.

    If your optitian can't help then see your doctor.

    I have tried it before to reset the appearance settings and the size and it helps a bit.
    Tnx Sbowler.

    Maff et1 : “I wouldn't go with a PJ for this kind of use. Especially not a DLP.”

    Why not DLP?

    I work in a room where the sun light is never sufficient and we rely mainly on white
    fluorescent light shielded by diffusors.

    I talked with an optitian and he suggested the glasses which I now have, but I still feel that this is not enough.


    And finally about the Poll: well, looks like being back on the starting line ;)

    I'd recommend against DLP because of the rainbow effect (the image is made by quickly displaying the entire image in different colours), even if you don't suffer from it in best conditions then you will start to when you are tired or have been looking at it for along while. This is especially true of data DLP's as due to the number of segments and speed of the colour wheel (they have a white segment to boost brightness).

    Any PJ wil need to be used in darker conditons which is also bad for eyestrain.

    I deffinately prefer a good quality LCD monitor, I've never worked for long periods on a PJ but there has been nothing in watching films on mine that has made me think it would be good to work on.

    What is the rest of your work environment like, the eyestrain could be a side effect of general tiredness which could be caused by heat or humidity. How often do you take breaks aswell, you need to give your eyes a rest.

    Do you also get it when only using your machine at home, and do you get anything similar on days when you don't use a PC at all?
