I made a very nice purchase on saturday afternoon.
Goodmans LD1501 15" LCD TV (http://www.comet.co.uk/comet/html/cache/455_152340.html)
I takes a PAL signal, AND a 15pin VGA signal.
My A1200 runs perfectly with it. It displays all the different PAL modes I've thrown at it, and also works perfectly with the Voodoo 5500 PCI card shoved in my Mediator bus board.
Who the hell needs a scandoubler eh? ;-)
I've got the following all connected up to this little beauty all at the same time.
Nintendo Gamecube (SCART)
DVD Player/VCR (Phono connections for L+R Audio and Video)
A1200 (Phono Video output and onboard Audio)
A1200 Voodoo PCI (VGA socket)
UHF TV Aerial (Coaxial socket)
and there is room for more inputs too!
Cost me £229. :-D

That looks like quite a deal you got there. Was there any flicker using PAL Superhires Interlace? I've been hunting for a scandoubler for some time, but it looks like this could be a far better alternative.

It flickers on PAL:1280x512 but Voodoo:1280x768 is rock solid.

That could be a nice replacement for my 1942 / Microvitec monitors. The specs say 1280x768 and I wonder how is the AGA resolution are displayed. Are they stretched by the monitor or can you switch that of on the monitor so that e.g. 640x480 is displayed as part of the screen ?
A pitty that is it NTSC.

Lower resolutions are stretched to fit the screen. It doesn't look bad at all though.
The screen is a PAL TV, but can display NTSC no problem.

Is it possible that you take a some pictures with a camera and post it to the Amiga.org photoalbum ?

Yeah, no problem.
Moved house 2 weeks ago, and I know my digicam is in a box *somewhere*! :-D

Thanks !
How do you switch between Voodoo and AGA resolutions,
is it a button on the monitor ?

Yeah, I just switch between AV2 input and PC input using the remote.

Oke, that is nice to hear. Easier then my Iiyama.

cool stuff...
I have been doing the same with my Samsung 17'' TFT-TV for a couple of months now...really good monitor...12ms response (no ghosting) and has vga-15, scart, rca video and audio in plus s-video...it aldo looks cool
Samsung 17'' LCD-TV at Komplett (http://www.komplett.co.uk/k/ki.asp?sku=124838&cks=SPK)
bought from Komplett.co.uk ... was also £4 cheaper than the aforementioned Goodmans screen...it's always worth shopping around when shopping for LCDs...internet store like www.ebuyer.com, www.dabs.co.uk and komplett do really good deals...
...my miggy got a new lease of life
:-)

Why didn't you post on here when you bought it? Or did you and I missed it.
Mine may develop a "fault" tommorow, and have to go back to the shop for a refund! :-D

I'll guess most TFT's with SVHS, FBas or antenne will work.
Now we have to choose the best one !

It flickers on PAL:1280x512 but Voodoo:1280x768 is rock solid.
How can a TFT flicker :-? In opposition to a CRT there is the full picture visible on screen at any given time.
So how can it flicker ? Really I'm just corious as it should be technically impossible.

If it doesn't buffer the interlaced frames, or if the analog signal's timing isn't perfectly clean, I can imagine there's a pretty good reason for this.

While TFT-TVs are handy for amigas they are not the perfect solution on their own...the monitors discussed here are not multiscan monitors (at least mine isn't) in that they do not sync to below 31khz when in (vga) monitor mode
They can display PAL resolutions because they are routed either through scart/composite or s-video and presumably go through the tv-tuner circuitry rather than go straight to the display...the circuitry 'emulates' the behaviour of a tv so well that flickering is possible because the PAL resolutions are merely passed through the composite video-in rather than the vga-15 connector
so basically, it is like connecting your miggy to a TV - you get exactly the same behaviour; PAL resolutions are slightly blurred and the flickering is also there - just as when you connect an amiga to a tv-tuner card on your PC...
It is fine for playing OCS/ECS games in PAL - but if you want to do anything which requires detail then a scandoubler/ff is still required...
The DBLPal/NTSC & Multiscan resolutions do not have this problem and again you get the same result you would expect to get from any other VGA monitor. On the minus side TFT screens have only one 'optimal' resolution (usually 1024x768 or increasingly 1280x1024) meaning that there is a (very slight) imaga blurring when using resolutions other than the optimal (this is because the resolution does not really change -rather some 'creative' adjustment is involved)
conclusion:
- TFT-TVs/Monitors are good but not perfect
(but are a good middle of way solution which turns out to be good bang/buck)
- TFTs+SD/FF are a much better solution (but they cost more, and SD/FF are not easy to find nowadays)
- Good CRTs & SD/FF are as close to a perfect solution as one can get (they are not girlfriend friendly however and may diminish your ANCKAT* allowance)

640 x 480 is NOT supposed to be squished and fit within the TV viewing area.......that is a mistake (A Huge one) that Microsoft screwed up and the PC world.
the correct resolution is 640 x 400......if you want the extra 480, then the width has to be 720.......being 720 x 480 as that is part of the Overscan...it makes no sence to have anything 640 x 480, but thanks to PC's they screwed up this royally so that Digicams take pics in that resolution, so if you tried to view it on an Amiga.......you would have to scale it to 640 x 400 to make it look normal, because PC's squish the extra 80 pixels into the Viewing area that is normally 400 pixels.
Amiga is the only computer that had the resolutions right when it comes to how they should be displyed on a TV.
Now everything supports 640 x 480, so the world is a twisted place.

These LCD's that take various NTSC and PAL refresh rates...now here's the important question: which of these LCD display sync to these rates via their RGB ports? Not many I'd wager. The corportaions are screwing the consumer. Companies that don't sync down below 31KHz just want to force you to buy multiple CRT's or LCDs.
mdma, what kind of input is the "AV2 input"?
leirbag28, NTSC provides enough bandwidth for 1536 pixels [1520 on alternating lines] (not that an analog system actually think in such terms) and 525 total lines (only 512 are active thanks to CC and other crap, and we're losing lines every year it seems). Realistically, 672x464 is what will fill most bezels on most TV sets. Yes the Amiga is the only computer that creates video-correct aspect ratios. All NTSC video should be done at 1520x512 ;-)
