Video Splitter - different resolution monitors?

[johnnyatgraham]

We've got a laptop running into VGA splitter that splits to a 15" monitor and a 19" monitor and Benq XGA DLP projector. Someone has said that the splitter reduces all the signals down to the lowest resolution. So because we have a 15" monitor, it may be reducing the quality of the signal to the projector. Can anyone affirm this or shed some light on how we should being setting up our situation? Thanks!

Conceputally you're on the right track, but the diagonal measurement is not indicative of the screen resolution. For example, your 15" monitor might be capable of a higher resolution than your projector! You need to lookup the exact make/model of your 3 devices to research their specifications to determine which monitor is the "weakest link".

I see how you could come to this conclusion, but your a bit off track here.
Unless your vga splitter/amp is also a scaler, then it doesn't posses the ability to change the resolution (chances are you'd know if it was a scaler, because the are significantly more expensive)

Although monitors are projectors are capable of many resolutions, they all have a native resolution, which is the resolution at which the monitor will look best. Assuming that your projector is the main focal point, my suggestion would be that you find the native resolution of your projector, and set the output of your computer to that.

And if he sets the output to the projectors native resolution, he may lose his 15" monitor.
Johnny, what's the purpose of the two monitors?

Unless its a very old monitor, you'd think it would handle 1024x768.

The 15" monitor (max resolution is 1024 X 76 is for the pianist to easy be able to follow the songs via of the Powerpoint. The 19" monitor (1280 X 1024) is for the song leader. The Benq projector (PB8253) has native resolution of 1024 X 768 but a max resolution of 1280 X 1024. Will the brightness of the projector be effected by any of this?

I'd run the whole show at 1024x768 to match the projector native resolution. If you really want to run at 1280x1024, you're gonna have to replace the 15".

Re "Will the brightness of the projector be effected by any of this?" - the answer is no.

And the projector will be having to scale the 1280x1024 signal down to its native 1024x768 resolution, so probably best all around to run it at 1024x768.

The latest splitters in market are smart enough to carry signals without degrading them....
