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 :D 8-).

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.

Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb :!:
Looking forward to summer in Somerset later in the year :)

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
