Title: An LCD-TV question
Post by: Caius on January 11, 2008, 01:37:31 PM
Seems to be a lot of LCD-TV and scandoubler related questions going on these days. Nevertheless, I have another one.

So I'm extremely tempted to grab a Samsung SyncMaster 741MP, which is a 17" monitor with TV-tuner and SCART connector. But I'm getting a little confused when looking at its specs. It's reported at 56-75 Hz vertical sync. Now, since I'm living in a PAL country, I'm a little surprised it doesn't go down to 50Hz? Do these monitors/TV's do some sort of upsampling?

The rated vertical sync is for the VGA input and has nothing to do with the rca/s-video inputs.

Looks like a reasonable choice for an Amiga screen. Presuming that's 1280X1024 @ 75Hz for the VGA it should serve you well.
I agree with the above also, the quoted V Sync will only refer to the VGA, your SCART input will work fine. :-D

@both

Thanks both of you. I expected as much, but I just hate wasting money on something that doesn't end up doing what I expected.

Yeah, I think that monitor will be nice for an Amiga. If I get some graphics card in the future, it'll act as a monitor switcher as well.

Us PAL users are lucky to have the SCART connector, the fellow Amigans with NTSC don't have that (they use BNC connectors I believe, and the signal is incompatible with RGB)

Hmm, more and more I get the urge to buy an Amiga, but in the Netherlands, good ones are rare and expensive. And don't even think of big box Amiga's  :cry:

AmigaKit has a good stock of A1200's, and at a decent price I think. Of course you'd still have to shell out for an accelerator card if you want that, and that may very well cost as much as the A1200. Or more.

I'm afraid the shipping costs are going to be steep, if I make a rough estimation I'll end up paying around €450/340GBP/$665 and that's way too expensive.

I paid ~£143 incl. shipping for A1200 + 40GB HD + PCMCIA Ethernet card. Did your estimate include tower, mediator, etc?

No matter. It's off-topic really.
Title: Re: An LCD-TV question
Post by: Krusher on January 11, 2008, 04:21:58 PM
Nope, A1200 build to order w/ new old stock A1200, os3.9, harddrive etc.

But you are right, way offtopic.

Hi Caius

I have two Syncmaster 741MP's(741MPi?) ;)) on my desk, the main one is running off the Cybervision643D in my A1200 @ 1280x1024.  The other I use as a video monitor for my vlab, as a tv and eventually it will be used as a monitor for my other A1200 or the A4000.  I use the "main" 741MP with the TV out of the A1200 and the s-video with my CD32 as well.

Very happy with the set up :D

Good to hear you're happy with it Pertinax, since it's the cheapest Monitor/TV solution I've found. At least where I live.

Shipping costs to the Netherlands are not expensive- we can provide shipping at a rate of EUR 18 for upto 10 Kilos

Thanks, I registered so I could see the actual shipping costs. But about €450 is just too much, for that amount of money I can buy an Amiga 4000 in near mint condition, and yes, it's used, and has no warranty, but I can justify paying that amount for an Amiga 4000, not a new old stock A1200.
Then again, I just don't want to spend more then say €250 for an Amiga.

If you start to sell Acube's MiniMig, I'll be glad to buy it though.

Could you guys please start a new thread if you're going to discuss buying an Amiga? Let's keep this thread to LCD-TVs.

I know, I know. I was the first one to bring it up :crazy:

Sorry, but I had to respond to amigakit's reply  :lol:
I just get sucked into the Amiga again.

LCD TV's for now on!  :-D

This monitor seems to be unavaliable in the U.S.  :-(
So the search continues.

That's because it's a PAL version only. You Americans are out of luck on this one because we use a different tv/video connector and signal, which happens to be compatible with the Amiga's rgb port. The so called SCART connector is absent on USA versions of LCD TV's

Sorry guys.

 :roflmao: LOL, but yes, SECAM is damn fine. It is interesting to note that SECAM video is often created as PAL however.

Just a little update. I eventually bought the Samsung SyncMaster 741MP. I have my PC on the VGA connector and the Amiga on the SCART. The VGA picture quality is superb. Best monitor I've had! The Amiga picture is very sharp, but it's a little "jittery". That means, it's not as rock solid as I had hoped. Interlaced resolutions looks as nasty as ever, so I'm running a normal Hires Workbench. I've overscanned it to 668x275 pixels in order to fill the screen properly. All in all I think it's as good as you can expect from normal AGA output.

Hi,

I'm also interessted in that TFT. :) Sounds like a perfect match for the Amiga...
One can connect GFX-Board to VGA and Monitor-Out to Scart. So if anything goes really bad, you will still see Early Startup Menu - at least I guess. :)
Can someone tell me, if the Samsung can make 50Hz on the VGA? I know the specs say no, but paper is patient. I found a HP recently that should sync at 60Hz, but does well with 50Hz.
As I do have a CV3D in my A1200, the resolution 1280x1024@50 is the max I can get out of it...

CU,
Mario

yes can you try it with an RGB to VGA adaptor and connect to the VGA port of the monitor to see if the Amiga's PAL output shows up

This is one of the reasons I have gone for DVI out on the FPGAARCADE board (it has analogue as well). You can connect the DVI out with a cable to the HDMI input of a digital telly, and it "should" work at standard PAL/ NTSC resolutions - I haven't tried this as I haven't finished the board yet :)

It's also a lot easier to scan double digitally the DVI out for a normal monitor than do it in analogue land.

Well,

I am speaking of a simple, connect Amiga gfx-board to VGA. No need to buy any adapters... :) And then, of course, use a 50HZ reoslution.

For US users wanting to use an Amiga on modern 32" lcds or any TV or LCD capable of accepting HDMI...

Why not try the following setup:

NTSC Amiga with a scart RGB cable connected to:

DVD Recorder with a Scart Input and an Component or HDMI out to a modern TV. Sinc these recorders are designed to record any signal in pal or NTSC from mulitple formats (s-video, RCA, SCart, Component) maybe they can promote the Amiga RGB to a LCD.

I have a Direct TV HD box that has mulitple input capabilities and can take the A1200's composite and scale it to an VGA monitor. Granted composite is not sharp at all but imagine how much clear a Scart Signal would be.

Has anyone tried this?

I've got LG Flatron L173ST (http://www.lge.com/products/model/detail/l173st.jhtml).

It does also have RGB capable Scart connector. The picture is sharp, although on bigger surfaces of the same color you can see some pixel noise. The border between colors is crystal sharp, though. And the best thing - you can use laced screen modes without the picture quality suffering. :)

Here's a picture (http://koti.mbnet.fi/tsaarela/TF/03112007010.jpg) of my setup. Looks better IRL. Mobile cams do have their limits.
