I'm gonna pick up a Samsung HDTV "monitor" of 23" and be a happy-camper with that one as it will have inputs for all my retro stuff, plus that it is 50Hz compatible. And it costs next to nothing...oh, and it has a tuner aswell -- which I ironically won't use ;-)


Which? Every Samsung I've seen is 56-83hz...

What model are you talking about? P2370HD or similar models? The specs say that it doesn't support 50hz through VGA/DVI, but only through the video-inputs (Component, HDMI, SCART).
Sometimes they will still do 50hz even if the specs say something like 56-82hz, but I'll have to wait till I get my MCC-216 to test it.
If not, I am thinking about a VGA-to-Component transcoder (without scaling and additional video processing) to fix that.

I'm looking at this one. Anyone able to confirm which inputs I could successfully use with Replay?

well I think it comes with DVI can use DVI to VGA adapter and DVI to HDMI adapter.

I have the P2370HD which has a similar panel and identical specs (just 1" smaller). I could test 800x600@50hz and 1920x1080@50hz over VGA and it worked fine.
Other resolutions such as 576p (720x576@50hz) were not accepted by the GFX-driver when using Powerstrip, so I couldn't test them.

Update: I used another computer with a GFX-card that was better supported by Powerstrip. 576p (720x576@50hz) was detected as 640x480@60hz and the lower part of the screen was cut off.
Therefore, I cannot recommend the P2x370HD-range if you intend to display 50hz-modes via VGA/DVI. Using the Component or HDMI input, 576p should work correctly. I will test a VGA to Component transcoder to test this.

Could the replay output at 100Hz instead, with each frame plopped out twice?

kedawa, Proberbly if you are prepared to sacrifice a significant part of the video memory pipeline capacity.

Or ask someone to make a DVI-2-memory buffer-2-DVI circuit externally ;)
(could output anything like SCART/CVBS..)

Hmm..a LED/LCD TV which does not accept 50Hz on its VGA / DVI inputs ? Now that is very strange. I am not saying it is wong, but it just sounds weird :)

Ayway, I am gonna go back to the store if the monitor does not work. Or better, I will bring the replay board (now in it's rather fancy mini itx black cabinet) to the store and just plug and test until I find one funky screen that handles my digital demands :)

Can we see some pictures of your Replay in the new case?

A Korean manufacturer (Samsung) locking out PAL modes for the European market? Naa... it's just that 640x480@50hz or 720x576@50hz is not a VGA standard.
But... 720x576@50hz (576p) is a Video standard, that's why basically all LCDs accept it via Component or HDMI (provided they have inputs for that).

Will you be emailing people who want to purchase on your unofficial pre-order list?

or do we need to pm you or something?

Yes, I'd like to get the board, too, and I don't know where/who to ask :D
Will ir be mass-procuded soon or should I place an order to be sure?
