I have just purchased a LT150 which I am stoked with. My set up is a non-progressive scan DVD player utilising the LT150 onboard scaler with an s-video feed. I also have a PAL sat feed also through s-video. My viewing distance is 4m, with a ceiling mount for the projector.


The next step is a screen, which I have no Q's regards due to some excellent posts covering screens. Also a progressive scan DVD player, hopefully capable of DVD audio playback (Are HTPC cards capable of DVD audio?)


The main query I have is the optimum screen size considering my 4m viewing distance. I am aware of the 2:1 rule, is this a diagonal consideration or a screen width? At the moment I find that if I go above a 1.5m wide screen( which is well inside the 2:1 rule) then I suffer from eye fatigue and end up with a headache mainly due to any fast panning shots. Could this fatigue be reduced with a scaler, and if so what is the recommended best bang for your buck?

I find that 1.4 - 1.5 screen widths away is about right (for me) with a XGA DLP (LT100). You might want to visit forum members in your area for a look at there size, etc. You can also get a rough idea by estimating (pacing off) dimensions at a local theater. Try different distances and see what you like.


I started at 1.57 screen widths away and bought a new screen that is 1.4 and am much happier. YMMV.

Thanks for the reply, How far away are you sitting from your 1.5m wide screen? Were you also suffering eye fatigue with larger screen sizes?


Cheers.

Sorry for the possible confusion. The dimensions I mentioned earlier were with respect to the screen width. In other words 1.5 screen widths is equal to a viewing distance of 1.5 times the screen width.


In my case I am setting 12' (144") from the screen. I first purchased a 92"x68" screen (distance of 1.57 screen widths). I decided that I wanted a wider screen for 16x9 material so I purchased a 104"x68" (custom Da-lite High Power) screen which I use at 104"x58" for 16x9 material (1.4 screen widths) and 80" x 58" for most 4x3 SDTV signals. For high quality 4x3 (e.g. IMAX movies on DVD) I can watch at ~92" x 68".


Overall I am much happier with the second screen. I do not see any pixels or get fatigued at this distance, etc. BUT it is a personal preference.

Gary,


How do you vary the screen ht between 58" and 68"?


Thanks

If you haven't mounted the projector yet, you can experiment to your hearts content. Just project the picture on a white sheet or a white wall. Do that for a couple of weeks until you get a feel for what size you like. Then order the right size screen. When the screen finally arrives, the picture will look *so* much better than the wall, you'll be happy with it, no matter what size you get! http://www.avsforum.com/ubb/smile.gif


If you have already mounted your projector, you have set your screen size. Without a zoom on the 150, at 4m, the image will be 2.438m.
