I dont know (why would I?)

You'll have to do some research on the net with that product code.

Although I wouldnt recommend importing one unless you know someone in the uk.

Nope :-(

Lots of Sony branded multiscan monitors dont sync down to 15KHz.

They have to say on their technical capabilities a minimum horizontal refresh no higher than 15(.75?)KHz

I got a second hand Amiga branded Microvitec 1438 off ebay last year for about £25.

Works fine except for a bad connector.

I wouldn;t spend £100 on one, I would rather spend that on a graphics card so I can use my Amiga with my VGA monitor.

Although i would rather spend £100 on a 1438 than £100 on an LCD TV anyday.

In the USA, is there an LCD monitor that will accept SCART analog RGB input at 15Khz.

I was looking at the Samsung 940MW SyncMaster LCD on the internet; however, I have not tried and do not own that LCD. Has anyone ever use analog RGB from an Amiga with Samsung 940MW SyncMaster LCD ?

All useless... they just tell you how to build the 23-pin to 15-pin VGA adapter (Shiney silver commodore thingy).

Only useful in AGA Workbench using dblPAL and dblNTSC screen modes.

Doesnt work in (most) games or demos.

I've got this Samsung LCD with the SCART connector.  It is fine for games, but text has some artifcating which makes it difficult to read when using workbench.  My 1084s has better picture quality, but I use the LCD because I don't have space for two monitors (my satellite TV and MacBook also connect to the LCD).  I'm planning to get a mediator + vodoo to use for workbench.

Alexh knows his monitors, I tend to agree with him about LCD TVs...

I have a SD/FF to an LCD monitor, and a 1438 connected to AGA. (dont ask why! :) )

For those that are interested, I got this reply from Microvitec.

"Currently we have 2 Amiga compatible monitors in our second user stock that have been serviced by ourselves.
Prices are £95 each plus shipping cost The monitors have the spec as per Desk-Scan 1402 see : http://www.microvitec.co.uk/products/desk-scan%201402.htm
If either was of interest the easiest way to buy these would be as a 'but it now' item on Ebay and I would list it and forward the link.
 
Your other options are to look for similar items on Ebay as they come up - good luck."


Good luck

LCDTV's are effectively the same as an Indivision / Toastscan Scandoubler. It is an EXTERNAL scandoubler.

They usually have OSD controls to change sharpness and other parameters of the scandoubler (like the screw on the back of the Indivision).

If you have blurry writing on your LCDTV in workbench you should try to adjust the scandoubler through the TV menus.

Also using a Workbench "PAL60" screen mode will help.

Choosing a resolution as close to the panel resolution will also help. The internal scaler in your panel will produce less scaling artifacts with a whole multiple of panel res.

So if it is 1024x768 try for a resolution of as close to (half) as possible.

Remember you also have a flicker fixer so using interlaced workbench modes are fine.
