Perhaps those are hardware specific issues and not related to all converters and all HDMI monitors and TV's in all the gin joints in all the world; when she walks into mine, I have 2 monitors (older Dell ST2310L & new AOC) and 2 TV's (Westinghouse) all 1080 x 1920 and 3 SCART to HDMI converters, and these do not have your problems.  I also don't seem to "game" as much as you do, spending more time on productivity programs.


There is a possibility they've improved their de-interlacing algorithm since I bought mine - if I get a chance I might capture some video so you can see it.

I'm not saying I don't believe you.  I'm saying I don't see it on my equipment.

@djos:

Hi djos,

Do you know if the CVS287 adapter actually converts PAL/NTSC video signal, i.e. if I use a PAL Amiga + an Amiga SCART cable + the CVS287 adapter and connect it to an NTSC HDTV with Component inputs, will it work?


Thanks,

x56h34

Thanks. So it seems like the SCART to HDMI adapter is the way to go when needing PAL<=>NTSC conversions, however the SCART to Component adapter may be a better choice when it comes to general picture quality, especially when there is motion on screen.

Essentially, yes.

Btw, I noticed a new RGB-HDMI converter claiming a blur-free picture - no idea if it supports 15khz Amiga RBG tho but maybe worth a try:

@Djos, when saying soft do you mean somewhat motion blur like picture?
Ive seen HDMI recordings with a good capture card from that exact converter that Danbeaver was using with gameplay from a Sega Genesis/Mega Drive and seems to be quite good and I don't notice any motion blur, I just ordered one to see how well it works :)

No it's not like motion blur, it's more of a soft focus appearance - it is quite noticable in games when a background stops moving because it suddenly goes from soft to sharp.

You can see it moving the mouse around workbench in the default modes as the mouse pointer goes soft while moving and then sharp when it stops.

Sounds like one could build a project to do the DVI/HDMI stuff reliably..

Perhaps even bypassing the internal DAC:s in the Amiga.

Ill give it a go and see how it turns out, thanks for clarifying tho :) I got the Indivision AGA mk2 in my A1200 so this will be used for other old consoles, if it's acceptable ill rig it up to 15 of my consoles and build a huge scart/compisite switch :)

I'm not claiming nor attempting to convert the world to HDMI, but in a price to quality (where there are soo many cheapskates in the Amiga domain) this beats the alternatives by costing half to one fourth as much; and if there were "motion blurring," well, duh!  Its motion, Dude!

No need to be so defensive Dan, im not calling it rubbish, im just saying that if you have component inputs the RGB-YUV converter provides a better quality conversion and leaves the higher quality electronics in your TV to do the scaling and de-interlacing.

:cool:

PS, it's not motion blur like Mouse trails on an old LCD, it's a visible softening of only the parts of the picture that are moving in most games.

Are you sure the signal from a PAL Amiga won't work through the adapter to an ASTC TV?  All TV's nowadays use the same resolution, there's nothing inherently different in an ASTC to a DVT-B TV.  They're produced in the same factory in China and pretty much the only difference is whether they get an ASTC or DVT-B tuner stuck in them.

How is $60 for the hdmi converter "half" the price of the $60 ypbpr converter? :hammer: lol

How is $41.95 half the price of a DCE Scanmagic, a CompServ/Arxon, a 4-button thingy on eBay, an Indy AGA, a host of other solutions, and is available.  I don't see many monitors in the states with component inputs, but I could be wrong now.

The OP was primarily asking about using an Amiga on TV's, most TV's still have Component inputs.

Hi' all.

I realise that there are quite a few posts about how to get the best signal from your A500/600/1200 etc. to your TV/Monitor. However, I cannot seem to find any, which is exclusively about transferring signal from Amiga to a modern TV, with some sort of HDMI cable.



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.
