I will be upgrading from an Infocus lp530 and am considering either the SP7205 or SP5700. I have a throw distance of 13 feet, a 100" diagonal screen and will have ambient light during the day (windows) and I will have some light on at nite (to read the paper). The lp530 has 2000 lumens with a 400:1 contrast ratio. If I go with either a 5700 or a 7205 will I just be trading lumens for cr and the net effect will be the same? Or will I see a noticeable difference and corresponding WOW factor at the same time if I upgrade? Of course anyother help or suggestions would be apprceciated.


Thanx,


Rick

If you're in no rush, I would wait until the sp7205 actually hits the streets. Then you read the reviews from forum members vs the biased reviews in magazines. Also, if I'm not mistaken the sp7205 will be able to display a hi-def picture. I dont think the lp5700 does. Someone correct me if I'm wrong please.

The 5700 displays a pretty amazing HiDef picture, but it will not squeeze every bit of detail out of it like the 7200/7205 will. The 5700's resolution is 1024 x 576, where the 7200/7205 is 1280 x 720, true 720p hi def.


The 5700 is plenty bright - in fact, one of the brightest home theater pieces out there. It should provide a smoother, higher contrast picture than the LP530.


Is your screen 16:9 or 4:3? The 5700 is 16:9 native, while your 530 is 4:3.


Good Luck!

You are right in that the 5700 cannot display HD at HD resolution (720p or 1080i). It can display an HD source, but with only 576 lines of resolution since the 5700 uses the blasted Matterhorn chip.

angilasaurus -


I did have a 4:3 screen, however I will be updating that as well to a 16:9. Any thoughts as to the lp530 having 2000 lumens with a 400:1CR and the 5700,7205 with 1000 lumens and a much higher CR? Would I effectively have the same "look" on my screen in a uncontrolled ambient light room? If brightness of pj is needed for a lit room during the day, should I stick with the lp530? Does CR and resolution deteriote rapidly in a uncontrolled ambient light room and therefore would I not benefit from upgrading?


Thanx for everyones input,


Rick

Did you check the throw calculator for the 5700? I have a 119" screen and needed to be 16' back. The 5700 might not work in your set-up.


As far as comparing the 5700 to the 720x, for DVDs I would say save the money and get the 5700. If you will be watching alot of HD, get the 720x. HD does look great on the 5700, but it's better on the 720x.

Presently, our satellite provider only has 6 HD channels and all the networks have HD during primetime. This pj will be used for for daily watching of tv programming and some DVD. Should I wait on the 7205 until there is more HD programming and update to the latest greatest.


Does anyone know if I will see a difference from the lp530 which has 2000 lumens and 400:1 cr compared to a 5700 or 7205 which has 1000 lumens and a higher cr? The pj will be in a non-ambient light controlled room, not a home theater setting.

I can't comment on the difference between the lp530, I've never seen one. The 5700 will be better in situations where there is ambient light. As was said earlier, it is one of the brightest DLP projectors.

These are hard questions to answer without having seen the LP530. Certainly watching the 5700 at night will look considerably deeper than the 530 under the same conditions. During the day, who can say? Yes, all the ambient light will destroy most of the contrast advantage, but exactly how much is impossible to predict. Does the light hit the screen at an angle? What kind of screen material are we talking?


Nothing will beat a combination of a 7200/5700 and a Stewart Firehawk for ambient light - screen choice can make a dramatic difference for the above scenarios.


Good Luck!

Rick,


I see in later posts that you have made the switch from 530 to 7205.


I am in almost the same state - an LP530, 4x3 1.3 gain white screen, without complete light control. Wondering about the switch to a higher resolution / higher contrast / lower lumen projector.


How well do you think the 7205 compares with the 530 when it comes to brightness and overall effect (I know the contrast will be better).


On a related issue - does anyone know if the LP530 shuts off the clear section in some input modes?


TIA,


Jim

There really is no comparison between the two. My 7205 is just as bright as the 530 but the real difference is in vividness and punch of colorsn - almost 3D like. Obviously the blacks are blacker and the whites are whiter. Also, the 7205 has quieter color wheel.

Does anyone know a spec on the noise output of the 7205? I cannot find it anywhere.


Thanks

Before I purchased my Infocus 5700 I looked at the 7200 both with DVD and HD and from the distance where I was sitting (about 13 feet back with a 110" screen) I could not see a difference. Maybe my eyes are not great but I think that unless you plan to sit closer than 1.5 to one (less than 12 feet back for an 8 foot screen) I don't think the difference in cost is worthwhile (about $2,600 at that time-February of this year).


Of course some people want the very best and are willing to pay for it but I don't regret my decision on getting the 5700 with a Da-Lite HCCV gray screen.

If you are concerned about noise I can tell you for sure they are not quiet. Just about the same noise as everyone else
