It's the signal, not the projector.

I have the mp771 model. My set up: 2 benq mp771 and 1 mitsubishi ew223 short throw. The 1st mp771 is the left projector, the 2nd is the mitsubishi (center) and the other mp771 is the right projector all...

Swap the two MP771s over and see if the fault lies with the projector or not. If the problem image swaps over then your two projectors are behaving differently. Perhaps a factory reset might help.

I'd say that it is more likely that the problem lies with your graphics card settings rather than the projector. Projectors, in general, have a native resolution. Most of them will accept non-native resolutions and interpret them to fit, but the actual resolution of the projector can't change. Triple Heads to Go are quite tricky to setup. You should check the TH2G manual and see that the screen resolution which you are attempting to use is supported, the analog versions are quite particular.

Adjust your graphics card settings and see if that helps (This is where you will find the solution!). You need to compare possible settings with those of the TH2G and the projectors (The projectors get 1/3 if the TH2G accepts and splits the signal properly). You should be able to view the actual projector input settings to see how they compare to what you expect.
Start at the lowest 12x3 screen resolution that the TH2G will accept and see if that helps. Make sure refresh rates are set to match too.
It can be a fiddly process, however once you find the correct settings then it should all work great for you.

My projector only projects the first image from my computer. When I fix the connection, it freezes on the new first image.

There is a "freeze" function available on the PR52 remote. Please make sure this is turned off / disabled.

Infocus X1 picture freezes and dissapears and then comes on again

your display settings may be off, so change settings to factory reset and you may have to drop the resolution on your computer. you may also have a bad cable, so try a different cable.

The projector switching off after 30 seconds

check the following :
1.does the lamp glow u get the connected image
3.if yes does the screen show temperature or overheat
4.if yes then one of the cooling fans do not work properly & hence the unit turns to standby & goes into protection
if no 1 does not happen, then check the lamp physically,it should not show melted or breakage.
if the lamp seems ok, then the ballast is defective!

Shutting down after 2 min

Hi Jaco

You have to reset the lamp timer when you replace a light bulb on your Projector.

This can be done by going into the Menu and then go to either User1 or 2 ( you'll see a lot of the Projector's info on it ) Go to the lamp time and reset it.

Should do the trick !
