Finally I have found an equivalent of the upscaler sold on eBay (unfortunately only in U.K.) and tested by Dylwin:
http://dilwyn2.wordpress.com/2014/02/16 ... -displays/
That is generally available in many EU countries, as it is sold by Conrad under order no. 989271:
"SpeaKa Professional SCART and HDMI/HDMI converter"
http://www.conrad.com/ce/en/product/989 ... no-Adapter
I bought it today afternoon. It works well with my QL (RGB-SCART cable) and Samsung LCD TV/Monitor (HDMI). I can feed the VGA input of my monitor using a HP HDMI->VGA converter connected to it's output.
I have put some pictures of the different screen modes here:
http://gigant.chem.elte.hu/ZXSpectrum/Q ... converter/
The best modes were the 720p and 1080p when using the RGB input. The 800x600 mode was blurred, the 1024x768 was a little bit better and so on... I got the worst picture quality using the AV composite input from the SCART cable. (This unit uses the standard SCART BLANKING signal for composite<->RGB selection.) Of course the HDMI->VGA conversion decreased the picture quality and the picture was blurred as for the 800x600 mode.
Thank you jimre - some people did mention to me it was hard to get the original unit in some countries, so I am very grateful to you for letting us know about this.

I wonder if we should start a thread to see who wants one and have a cut off date, after which a bulk order could be made - possibly at a discount?

Seems like a great idea, this seems to be a 'de facto' method of connecting a QL to a flat screen HDMI TV which many members have had success with. Go for it - put your names down for one and encourage Rich to look into this.

Has this died a death
I have obtained one HDMI converter, but have found that it also works brilliantly with a Beeb
.
So if there was a bulk order that brings the unit cost down, I would add my name to the list as I would buy at least one more, maybe two (for use in place of a failed auto-SCART switch box on the main TV).
For both the QL and the Beeb (BBC model B), I used SCART leads from
retrocomputershack. However, when I tried my ZX Spectrum +2B and +3, I got a double image (like a very sharp single ghost image overlaid on the first sharp image). I think this may be a problem with how the SCART lead feeds some of the control signals to the converter box, but I have not investigated further.
I have not yet tried any other computers.
You can see screen shots for both the QL and Beeb
here.

Hi,
Looks great, what sort of quantities would attract a discount, maybe it is something I can help with.

Hi,
Strange, I was just thinking about this, what are the details of the SCART connection?
I will maybe buy one, did you get one from Amazon
