Not sure what you mean. In this case, I am using an actual widescreen LCD monitor at the 4:3 aspect ratio. Any resizing would distort that and cause other undesirable effects.  

A better question is why this exists in the first place. Perhaps something to do with "exceeding the limits". I'm just guessing.

Can't you just resize the display on the TV to get rid of these?  That's what I would do.  ;)

I mean, in the most technical sense, press the buttons to make it go away?  ;)  Nevermind, here's a better idea: use a border blanker to make the background color (gray in your screenshot) black.  Obviously not helpful in games, but better than nothing?

Does anybody have good solid experience on the easiest/cheapest way to get your Amiga out-signal into a HDMI cable and on to the huge and wonderful livingroom TV? :-)

All best,
Anders, Copenhagen.

For the A1200, If you want to skip easiest/cheapest and just got for the best then I'd suggest Indivision AGA with kipper2k HDMI adapter. I wasted money on several less satisfactory video solutions prior to getting this setup.

If you are not in need of a RF modulated output then you remove the RF modulator box and put the kipper2k there.

good luck :)

That is the best advice for an A1200.

My results are much the same as magnetic's. I see a rock-solid monochromatic image, in the correct aspect-ratio as well! The TV reports it as 480i.  :)

Unfortunately, when I switch to PAL mode, the screen goes blank.   :(

I will test an interlaced screen when I get my WB 3.1 booted up again.


I get full colour output on both pal and ntsc though the ntsc picture is better the PAL is a little "fuzzy" but still looks good

i'm also thinking of getting this:

http://www.monoprice.com/Product?c_id=101&cp_id=10114&cs_id=1011405&p_id=8124&seq=1&format=2

that way in theory my AUDIO would be transferred over HDMI (to my receiver) as well.

I guess using this you could skip the kipper2k, but I'd just use a small DVI to HDMI adapter because I already have the kipper2k adapter.

Side Note:

Those SCART to HDMI transfer audio as well if you use a SCART cable (like Amigaikit's) that allows it;  that being said, MonoPrice is a company with a stupid name that sells excellent products (I have at least 2 of theirs) for reasonable prices.  

They even have features they don't advertize: my 5-port HDMI switcher automatically selects the signal varying the most, but allows selection via the remote or just a finger wave in front of the IR receiver.

I actually bought a SCART to HDMI adapter (from deal extreme) and an amiga SCART cable, that being my only SCART device I was never able to figure out why it did not work. I'm guessing not all it was the dx adapter and not the HDMI adapter from amigakit.

Hmm, unfortunately it sounds like you have a TV that only supports 60hz via component video. :(

I'm a little late getting back on this thread to report my experience with one of the SCART to HMDI devices. It does the job, but I have to agree with djos on the soft-focus effect with objects that are in motion. If you're only a casual user and are sitting at a distance to a large screen TV, you probably won't mind this at all.

Yeah that issue drove me mental and gave me headaches!

Quote from: jdryyz;780534
In addition to that, however, I found another problem I find more offensive. Take a look at the attached image. Why the zipper-like pattern? I am using overscan on my Workbench screen to maximize the display, but since it shows up on games as well, I have no control over those.

This happens on NTSC signals only (what I will be using most of the time). PAL signals do not show this.

@djos -- does the SCART to Component adapter do the same? I have an NTSC/PAL friendly LCD panel now with a component input. One of these devices could be a good fit.

That is a strange artifact, TBH i've never seen it on on either the RGB-HDMI or the RGB-YUV converter no matter whether im using 50hz or 60hz.

There's certainly no harm in trying the RGB-YUV converter if you can find a seller that offers a money back warranty if you doesnt work for you.

4 pages of discussion when the solution was nicely summarised by paul1981 in post #5.  

The indivision not only provides the best quality output but also provides 1024x768 and 1920x1280 resolutions.

There are two target audiences in this thread though: 1) The A1200 users who can install more capable internal video expansions and 2) The A500 North American users like myself that must rely on external expansions only.  :D

Agreed. I am curious as to what your SCART to HDMI converter looks like then. Perhaps you found a better one than mine.
