OK so I have had my projector sitting on a cart in my family room for about 3 months now and I’m getting sick of it being in the way. So I want to mount the projector on the ceiling and have the screen across the room to project on. However the screen will be mounted on the wall and can only roll down about half way down because the screen is above the fireplace. So the screen is going to look like a wide screen rolled down. If I have my computer connected to the projector I don’t understand how I can set up the resolution or what ever it is to fit the image (the desktop of the computer) on the screen. Because the screen is just about the right size for a wide screen movie. But turning on the projector and using my computer to open up the DVD player application without being able to see the screen. Is there anything I can do? I hope you can understand what I am talking about sorry it’s a bit confusing.
thanks

Full Version: How Do I Fit The Image On My Screen
Try using Powerstrip(freeware) and set your desktop screen resolution to something
that will fit on your projection screen.
that will fit on your projection screen.
thanks, i got powerstrip and im not sure if im using it right. I set the resolution very low but the image is the same size and everthing is still off of the screen(to the right and left) just the icons and everthing are blown up very big. hope i can fix the problem without moving the screen or projector.. any help is very thanked

changing the resolution alone wont do it.. now youre just using a lower resolution over the same area. you need to set usable pixels smaller as well.. so for example say you set resolution to 800x600, you must set usable pixels to 800x600 else the image will still stretch over the entire screen.

ooo ok...so it will show the image on the lcd screen in like a area that wont fill up the whole screen but will leave black borders all around

ah yes thanks for that guide however i still cant find out exactly how to do it.. If anyone has actually done this (changes the res but didnt strech the image out just left unused pixels out making a big black border all around) could you tell me how you did it.
thanks so much

What LCD are you using ? (Make & Model)
Are you only trying to "shrink" the height or height & width of your projection ?
What is the make/model of your video card ?

Before you start I suggest the following. Remove the powerstrip software, do not save any resolutions if prompted to do so (need to clear out the registry). Next, fully remove your video card display driver. Reboot. Re-install your video card driver. Reboot. Re-install Powerstrip software.
You may try this procedure without removing/reinstalling Powerstrip and display drivers as described above, but if it doesn't work, you should at least try removing/re-installing the drivers...
If you are running on a DVI connection, no promises that this will work (and in fact in all likelyhood, it will not)... you'll need to use a VGA connection for powerstrip to work properly.
Be sure you are running in the LCD native resolution as selected through your video driver software. (1024x768 for a 15", or 1280x1024 for a 17") Now run powerstrip. You will need to select "Display Profiles" - "Configure..." (right clicking the powerstrip icon in the notification area with windows XP). From here you should see your resolution displayed on a slider bar on the right hand side... be sure it is the correct resolution as selected by your video card driver. Now click on "Advance Timing Options"... from here you want to select "Custom Resolutions" near the bottom on the left hand side. In this dialog, you want to select the check box near the bottom right hand side "Lock Total Geometry". Once this is done you can set the "active pixels" located on the top right... you'll be setting 1024x576 for 15", or 1280x720 for a 17" depending on what LCD you have. These are both 16:9 screen sizes. Now you want to select "Add New Resolution" at the bottom right. You may or may not be asked to reboot your computer. I would suggest rebooting regardless. After your booted back up, be sure powerstrip is running, then select "display profiles" - "Configure" and this time using the resolution sliding bar to select the new resolution you just added (1024x576 or 1280x720)... with any luck you'll end up with the windows desktop in a 16:9 format on your wall !!
Good Luck,
gs

First of all, thank you for writing this up. Many people here have suggested Powerstrip to force letterboxed widescreen, but none have detailed how to do it. I'll try this tonight, and if it works, I'll... I'll... I'll send you a moose or something!
One question, though:
At what point would luck enter into it? Having bought Dell instead of ViewSonic? Having chosen NVidia instead of ATI? Just wondering if you knew any more specifics.
Thanks again.
.. oh yes... one more thing... if you plan to do any gaming, you may be in for a problem, and that is, games do not scale to fit this new resolution. so, even a 800x600 game will not fit in the 1024x576 resolution, it will override the powerstrip settings and go full screen...
... if you have a 17" LCD, then a 16:9 resolution would be 1280x720... however, if you game, you may want to consider running a 1280x768 resolution. why ? ... because if you run a 1280x768 resolution, you will be able to game at 1024x768 within the 1280x768 window... well, not exactly, but it would appear that way 'virtually', by overwriting the existing 1024x768 resolution with a new 1024x768 resolution that will run inside a 1280x1024 window (ie. you'll get a 1024x768 resolution that is letterboxed and pillarboxed on your monitor)...
sneeky, sneeky this little program can be...

ha. should mention that I was running ATI 9550 card with a CMV-520D panel, using the VGA connection.
I don't really believe that it should matter, this program is very versital among the major graphis card chipsets so I think it should work... believe me, I went through the learning pains of using this program... at one point I resorted to searching the registry for '576'... if it had anything to do with video resolution (ie. 1024x576) I deleted it... that was after I couldn't get it to work for beans and had "added" and "removed" all sorts of timings... I do believe that only running with the VGA connection is the single most important part when attempting this.oh yes, another important thing was at one time I could only use catalyst 5.13 driver or lower, otherwise it would not work... I believe this is not a problem with the newer drivers that use the NET framework, but if you have troubles, and are using a supported ATI card, I would try catalyst 5.13 or earlier version of drivers.
Hope this helps.

ps. the elusive "chocolate moose" would be wonderful
wow GadgetSmith thank you very much for all your help your a life saver. I will be trying this out later tonight or tomorrow ive been very busy. But ill be sure to tell you if it works. thank you again

i was thinking and could it be possible to get a long throw lens to solve the problem and just get the whole image on the screenand keep the resolution (1024x768 for a 15)?

yup. will require making the box longer as the FL of the triplet will increase... will need a new field fresnel too...

O ok...well so many choices..Im pretty new at this and not sure what is the best. A little background, I’m 15 years old and in high school, i made the projector the end of 8th grade. I have the entire standard lens and the light kit all from lummenlab. It is the standard box design and the 15" CMV-1512 lcd screen. The projector has been on a cart in my family room for awhile and i got sick of having to set everything up every time i wanted to use the projector so i decided to mount it on the ceiling. So the way my roof and ceiling are made, the only way i could mount the projector was far away from the screen (its about 11 feet away). So the image is way to big for the screen, the screen which is a 8x8 screen 1:1.. So as you see i have a problem...Would you suggest that i try using the program and everything or would it be easier and possible to use the pro lens for the projector without moving the distances of the screen and projector as how their set now
thanks so much
nick

Using a longer throw triplet is the best way as this will maintain the quality of the picture. If your strapped for cash, you can use powerstrip to reduce the active area of the LCD until you get the cash for a new triplet 
New triplet choices... based on an 11ft throw and a 15" LCD, the LL Pro Triplet (500mm FL) will get you an approximate 54x72" Projection (90" diag)... using a 650 fresnel in a split setup (for keystoning). A 450mm FL triplet (bessler, american science, etc) will give you just over a 60x80" projection (100" diag)... using a 550mm fresnel in a split setup.

oo ok...thanks so much. do you know how much longer i would have to make the box?

In the case of the pro lens, about 8", but you can check the calcs with the focalength calc II in the tools section.

ok thanks so much...I set up powerstrip and i got it to work but powerstrip puts the image on the bottom corner of the lcd screen. So i was going to order the pro lens this wekend but i remembered the fresnel lens.. Will i be able to cut the field lens so i can fit the lens inside the box?

There are options within powerstrip to move the image where you want it... kind wierd that it put in the corner anyway... but you can fix that.
As far as fresnel lens, yea, you'll likely have to cut it to fit your box. This is not too much trouble using a straight edge and a nice sharp utility knife. Just be sure when you do cut it, you need to maintain the center of the fresnel lens on the optical axis. What this means is that if you need to trim 3" off to fit the box, you'll need to trim 1.5" off each side... this will maintain the center of the fresnel to the center of the LCD, lamp and triplet.
good luck
