hello there
If I have a notebook without a VGA output how can I relate it to a datashow what cable I have to use to conserve the best quality of the image
or is there any other solution to this?
thank you

any suggestions [::)]

What output options do you have? What input options does the projector have?

it has a VGA output

it has an VGA output
The output from the projector will be the light it projects. If it has a VGA input then it will need an analogue input signal.
What outputs do you have on your notebook? The likely outputs, apart from VGA, which you've already said you haven't got, are DVI-A (analogue), DVI-D (digital), DVI-I (analogue or digital) and HDMI (digital). If you have a DVI-A/I output then you may only need a converter cable but if you only have DVI-D or HDMI then you'll need a converter to convert the digital signal from your notebook into an analogue signal for the projector.

Thank you LeeE, I only have HDMI output on my notebook
by using a converter cable, does the quality of the image remain good enough?
-
If you only have HDMI output from your notebook then you will need more than just a converter cable. A converter cable just has different connectors on each end but they won't be able to convert a digital signal into an analogue one.
After a little bit of digging around, it seems that converting from HDMI digital to analogue isn't practical, partly because of license issues tied to the HDMI technology.

If you have only HDMI output on your notebook (i didnt realise things had changed so much) then short of finding a projector with a HDMI input perhaps you could look for a digital tv in the place you are giving your presentation. Flatscreen tvs from the last few years tend to have at least one HDMI input port. It is possible you could find a video-recording device (hard-disc, dvd, blue ray etc) that has a variety of input sources (ie incl HDMI) and a variety of output formats (ie incl VGA) but this seems a stretch. personally I would copy presentation onto usb drives and borrow a laptop that has the presentation programme you need and a vga output.

Thank you guys for these clarifications

It is suprising the high cost of HDMI Scart converters, I have recently purchased a DVD with an HDMI output for £28.00 and a Freeview box with HDMI output for £25.00 so the electronics cost little but no Scart to HDMI converters are available for less than £60.00.

Myriam,
If you don't mind telling us, what's the make a model number of your notebook? I'd like to take a look at the spec.

At first glance this looks like a possible solution if your computer really doesn't have VGA output ...
USB2.0 to VGA Adaptor ... £49.99

Myriam,
If you don't mind telling us, what's the make a model number of your notebook? I'd like to take a look at the spec.
yeah, it is a netbook Dell Inspiron 11z CULV

Looks like you're right about no VGA output ...
The 11z includes the standard three USB ports, flash memory reader, headphone/microphone jacks,
Ethernet, WiFi, and an HDMI output.
Unlike some of the other options, there's no VGA port.

hey there I found 2 solutions
-HDMI/DVI --> HDMI/HDMI-->DVI/VGA
-USB/RS232 if the datashow has an RS232 input
-
RS232 is a serial I/O interface and I doubt it would have the bandwidth for video.
