Hi Sue, On your first concern, a possible reason for the 'Sync is out of range' is because your laptop's resolution is just too high for the projector to handle. You may have to manually lower down your screen resolution (right click on a clear area of your desktop, click on properties, settings tab, move bar of screen resolution towards the left). Try different settings that will give you best performance without the projector rejecting the input signal. Am not sure about your second concern though, offhand your description sounds like video noise. You may have to check that your connectors are firmly plugged in. A longshot is to remove any possible source of interference like wireless phones including your mobile, WiFi AP and the likes. Perhaps you give the first suggestion a try and see if the purple dots disappear when you have the projector running ok. Further you may have to reset your projector if it's got one. Normally it's a small button clearly marked RESET somewhere at the rear of the unit. Hope this works out for you. Pls comment/post back should you need further information. Good luck and kind regards.

SOURCE: 3M X75 LCD Projector switching slides from the remote with powerpoint??

Hi Dan_waddy

There is a USB cable that came with the Projector ( one end smaller than the other ) The smaller end goes into the back of the Projector and the normal 2.0 USB end into your PC - This enables you to flick through your slides with the standard Projector remote control.

If you do not have such a cable , you could get one from most good PC and AV shops.

Thanks for using Fixya !

Check for corrosion where the bulb sits in. Is there a fuse required. Make sure you handle the buld with cotton gloves (oil from hands not good) Let me know if that works.

How to Connect Laptop to Projector

How to display computer image on TV or projector
How to display a computer image on a TV or projector All modern televisions and projectors have one or more ports which allow them to receive and display an image generated by a computer. Both desktop and laptop computers are capable of connecting to a TV or projector, provided that they have the appropriate cables. The following sections contain instructions for using your TV or projector as a computer monitor. For best results, we recommend reading them in order.
Identifying available connections
Connecting computer and projector or TV
Display using Desktop
Display using Laptop
I don't see an image on my TV screen

Identifying available connections The first step in connecting your computer to a TV or projector is finding an identical port on both machines. Once the matching port has been identified (one that is the same on both your input device and output device), you need the appropriate cable to connect them. This section contains a picture of the back of an Epson projector and its available connection ports; as well as descriptions of each.

HDMI
The HDMI connection is very popular among display electronics. In fact, nearly all modern televisions and projectors feature HDMI ports. Most laptop computers support HDMI and it is becoming more prevalent on both desktop as well; even without a high-end video card. HDMI is quickly becoming the standard for all electronic equipment for its high quality signal and ability to carry both audio and video signals. The image to the right is that of an HDMI cable.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-1.jpg VGA
The VGA connection is the most common among both desktop and laptop computers, is found on most projectors, and some TVs. The VGA cable has a 15-pin connector on each end that plugs into a VGA port on each device. Due to the fact that most televisions do not support VGA, we recommend using HDMI for their wider range of compatibility.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-2.jpg Tip:VGA cabling is universal for devices that support it. For example, the if your desktop monitor that uses a VGA cable it, that same cable can be used by a laptop to connect it to a projector.
Note: If you are using an Apple desktop or laptop you need a VGA adapter to connect a VGA cable to the computer.

DVI
The DVI connection is newer than VGA and it offers a sharper image. Although the DVI port is not shown on the Epson model above, it is still somewhat common for projectors, not so much for televisions. It is mostly found among desktop computers for monitors, but some laptops have DVI connections as well (Apple laptops are more commonly known to support DVI than any other brand of laptop). Since finding DVI on a TV or projector is more difficult, we again recommend using HDMI cables.
Tip: There are special cables that convert from DVI to VGA or DVI to HDMI and vice versa.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-3.jpg
Composite Video
The composite video connection is quite common on a TV or projector, but it is nearly nonexistent on modern computers. This connection is the yellow female cable on what is normally a three bundle of red, white, and yellow. The only time you should see this setup is on older video cards for desktop computers.
S-Video
The S-Video connection is also commonly found on TVs and projectors, but solemnly on a desktop or laptop computer. This connection is a small step up from composite video, but is nearing obsolescence.

Connecting computer and projector or TV After you've identified what connections are available on both your computer and TV or projector, you're ready to connect the cables. If the same connections are not available for both the computer and TV or projector, you'll need to purchase a video converter cable that converts one signal into a compatible signal.

Desktop Computers For a desktop, you simply need to plug the cable into the computer and output device. If you don't see an image, you may need to change the display using the following steps.
  1. Press the Windows Key.
  2. Type Adjust screen resolution and press Enter.
  3. Find Display and click the down arrow on the right-hand side of the box.
  4. Select the appropriate output device.
  5. Click Apply then OK.

Laptop Computers If you're connecting a laptop computer to a TV or a projector you'll often need to "send" the video signal to the display device. The key sequence to do this varies depending on the laptop; but usually it's either: Fn + F3, F4, F5, F8, or F9. For example, pressing and holding Fn + F3 at the same time on my laptop sends the video signal to my connected TV instead of the laptop's screen. The corresponding key used with Fn may be labeled as CRT/LCD or have a picture of a monitor on or close to the key. Additional help and information with switching the laptop display can also be found on the link below.
Switching TV inputs Finally, if you're connecting a computer to a TV make sure it has been switched to the correct input. For example, if you connected an HDMI cable to your computer and the "HDMI 2" port on your TV, you'll need to switch to the "HDMI 2" input. This action can be accomplished by pressing the input button on your TV remote until the correct image is displayed.

You don't probably, your laptop screen is not exactly becoming magnified, the resolution is being lowered to match the maximum resolution of your projector which is only 800x600. They are setup as "cloned" together. You could try setting up an "extended desktop" rather than having the projector "cloned" with your laptop screen, that way you can change the resolution (within their allowed limits) of both displays independently. To do this, Right click on desktop and select video setting or the control panel of whatever video card you have. If you can set up an extended desktop, it is here that you'll be able to do it.

3M MPro110 will not display laptop display image


I changed my computer resolution to a lower value and this did the trick. I was also told that by doing this along with having the display shown only through the projector (instead of it being mirrored on both displays) should negate any problems. Thanx

Acer laptop stopped displaying to projector


Here is the deal. Right-click on desktop. Choose settings. Right-click on screen #2. Click on apply for new settings. The one additional problem you may encounter is the fact that the projector will display an area to the right of your laptop screen. In other words, move your mouse past the right edge on laptop screen. Look at projector image. See your mouse?

Hi there

If it is a DLP Projector it could be the Packlight Pipe Module that needs repairs.

Basically this part has 4 small mirrors facing each other and this normally happens when one of the mirrors come loose.

Very cheap to repair
