Title: 15Khz RGB YUV Video to VGA Converter Scaler For Amiga Atari Apple IIGS
Post by: WeiXing3D on April 09, 2013, 11:23:10 PM
Is anyone using one of this? Any comments or suggestions? What else would be needed to use with A1200?

That product works but not that well. Here are some pictures of when I tried it on my IIgs.


Produces horrible artifacts.

The desktop background is supposed to be solid blue.
And the progress bar is supposed to be red.

But in lower res modes it works fine ie 320x200

Uhm, but still better than my old Commodore 1084 :D

I'm wondering how it'd work with an Amiga 1200?

I've got that RGB-VGA Converter (http://www.ambery.com/rgbcgatovgac.html) too and it's terrible, my el cheapo GBS-8220 is much better - theres a new one that I've ordered to test that converts SCART RGB straight to HDMI or DVI-D (http://www.ambery.com/rgbtohdvisch.html) with native 50/60hz support and is only $45aud.

http://www.amibay.com/showthread.php?t=20468&goto=newpost

one of the lads over at AmiBay has had reasonable results so far:

Thats the GBS-8200, they work fine and are very cheap - PQ varies wildly tho from reasonable to poor depending on cable qulaity etc.

you really don't need those
if a monitor have HDMI input means that will accept 15hz amiga modes through VGA input
 because those monitors have internal circuitry that do the same that the adapter scart to hdmi
so you will need only a normal Amiga VGA adapter+ a monitor with HDMI input

examples:

Dell U2410
Samsung  syncMaster 2493HM
BenQ G2420

Most monitors and TV's outside of Europe dont support 15khz RGB modes because they dont support scart - the only screen I have that can handle 15khz via VGA is my 50" Pioneer professional Plasma Monitor in my lounge room.

My Samsung 21" monitor is a 1080p with VGA, DVI and HDMI connections. So which connector do you recommend to use with the A1200?

If your monitor supports 15khz modes you only need an Amiga to VGA adapter (amigakit sells them) and a normal VGA cable.

My Samsung monitor supports 15khz modes but only at 60hz and my miggies are all 50hz models.

the vga adapter must work on your monitor...you can try it first you buy another expensive adapter
on amikit they sell those for 15 or 20 u$ I do not remember very well
also you need a vga cable of course

it's not related if the monitor is euro or if support scart...is related to the monitor capabilities
The 3 monitors I listed above are not for the euro zone but guaranteed that support all amiga models through vga adapter
what I calculated is that if a monitor have HDMI input+vga ...there are 90% of chance that a normal vga adapter will works
of course I can't guarantee that all monitors will work...but the HDMI presence is the green flag to try

Ok I got my SCART-HDMI adapter today and initial impressions are very good - I've had it connected to my Samsung 22" LCD Monitor via both HDMI and DVI-D to test out the TV Modes and PC modes using my a1200 running ClassicWB Full with an AmigaKit DB23-SCART Cable.

I've found 720p@50hz via HDMI to be the best compromise so far as my screen isnt native 1080p. There is a very subtle softening effect around the moving mouse cursor and when things appear on screen in WorkBench (might be my Samsung LCD but im not sure yet) but this is not noticeable during during the 1/2 dozen demo's i've tried. Also of note in 720p@50hz, all scrolling is perfectly smooth. :)

The colour from this unit is absolutely superb, the best i've seen from a converter - I did have to turn down the brightness on my screen till the "black" border vanished (was a bit grey), but once I did this I was very impressed with the black levels and colour reproduction. The gradients are perfectly smooth too, firing up AGA tweaked Dopus reveals perfect colour transitions and no banding at all!

Oh and I fired up RSCP (Drive speed test) which gave the VGA converter a hard time and the SCART-HDMI converter easily and almost instantly shifted to the high-res laced mode with no fuss at all revealing a pin sharp display and no wobbly images. :)

Fine patterns, like the one in the WHDLoad "loading" window are also rendered extremely well. Another item of note is that it will convert 50hz to 60hz in the PC modes and scrolling smoothness, while not perfect as in the 50hz modes, is still decent considering.

Im prolly not going to have the time to take some pics for a few days with my prosumer camera so sorry about that, I quickly tried my iPhone 4s but it washes out the Red's and makes them look orange so just doesnt do the image justice.

One problem I have encountered (not the adapters fault) is my 19" Mitsi LCD seems to have a broken DVI-D port which is most annoying - at first I thought my HDMI-DVI-D cable might be faulty but it worked fine on my Samsung LCD. I cant even force the blasted screen to manually switch to DVI-D in the OSD, it just falls back to VGA each time. very frustrating as this is my Amiga Screen! :(

-------------------------------------------------------------------------------------------------

I also found some time to plug the SCART-HDMI Adapter and a500 into my 32" Sony Bravia using HDMI and the results are great - just a superb picture!!! :)

I find myself using the 1024x768@60 mode tho because my TV annoyingly wont let me squash a 720p or 1080p picture into 4:3 ratio!

That said I've been playing SWIV and BombJack on my 32" TV and having a blast!!! :D

The only issue I've found is with my AmigaKit RGB-SCART cable, the left and right channels are swapped around (confirmed with my multimeter) - so other than needing to swap the RCA's over, the sound conversion is excellent thru the SCART-HDMI adapter! :cool:

@ djos : where did you buy your scart-hdmi adapter ?
do you have a link ?

if I want my 1200 on my TVLCD, I have to go through my DVD player/recorder to get a picture (through scart). My Panasonic TV, although it has scart input does not recognize the signal coming from my 1200.

It also converts composite and s-video using a cheap scart plug adapter.

Btw mine came with a travel adaptor and the PSU is multi voltage. Also considering it is only $10aud dearer than a gbs8220 and is in a metal case I think it's very good value.

Ok I found the problem, on all my screens that support HDCP over DVI-D the SCART-HDMI adapter works perfectly via DVI-D or HDMI and my only screen that doesnt support HDCP is the Mitsi and as a result the SCART-HDMI adapter doesnt work.

So before buying a second hand LCD Screen for your miggy, make sure the specs say it supports HDCP over DVI-D (most modern screens do these days).

Ok so here's some Pics - a1200 @ 50hz to Samsung SyncMaster 225MS (set to 4:3 for correct image display) via SCART/RGB-HDMI Converter @ 720p50hz.

The pics are high res but were down sampled from 10MP as the files were huge - they still dont fully do the Picture Quality Justice! In some pics some colours are slightly washed out or the text not sharp, this is not how it looks in RL - especially the fine pattern from the WHDLoad screen, that is rendered really nicely in RL but hard to capture with a digital camera.

Bought a new Amiga SCART cable(Could build one but can't be stuffed) and the unit just now.  My main PC monitor is a BEN Q GL2440 hoping I can just plug into that.  Makes the desk much tidier with just one monitor on it.

Thanks for the tip.  It actually looks like quality hardware as well.

Does your BenQ support Hdcp? If it has a hdmi port it will for certain but not all dvi-d only screens do. I finally figured out this is why it doesn't work with my Mitsi 19" LCD monitor.

Hdcp is part of the hdmi standard and optional for dvi-d, it's just the DRM the movie studios forced upon intel when making the hdmi standard.

So you'll be fine as the same chip that runs the hdmi port usually runs dvi-d port. :)

Good news folks, using a scart plug adapter (http://i.ebayimg.com/00/s/MTAwMFgxMDAw/$T2eC16JHJG8E9nyfmIDKBP+52H4iO!~~60_35.JPG) it most definitely converts composite and s-video to Hdmi along with the audio.

I tested the s-video with my TiVo and got a superb picture, really quite impressive considering and it shows "scart SV" via the osd.

The c64 via composite also produced a surprisingly nice picture considering, like really really nice, was hard to believe it was composite, only the softness and bit of colour bleed gave it away but it was a much better pic than my Bravia TV produces when fed the same signal!

Bad news tho, using my very cheap c64 s-video cable it doesn't recognise the signal as s-video (shows "scart av" on the osd) and as a result produces a truly aweful aweful picture!

I checked my S-Video cable and it does have the 300ohm resistor but my c64 still wont work properly with my SCART-HDMI Converter - seems Commodore video is just too far out of spec for it to recognize it properly. :(

c64 Composite does work tho and looks surprisingly good.

Hi, the little SCART adapter I was showing before is just for Composite and S-Video input into the SCART-HDMI Converter - to connect an Amiga you'll need an Amiga DB23-Scart_RGB cable (http://www.ebay.com.au/sch/i.html?_odkw=amiga+scart&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0&_nkw=amiga+scart+rgb+cable&_sacat=0), the SCART-HDMI Converter and a HDMI Cable.

(https://dl.dropboxusercontent.com/u/71121999/c64/2013-05-03%2021.28.07.jpg)

I discovered using 100nF Cap and 360ohm resistor didnt work too well - the chrominance info was completely MIA and only the luminance info was getting thru. my wiring tested out ok the filter was obviously filtering too much.

Anyway for whatever reason I thought Id remove the filter and plug the c64 directly into the scart converter again and to my surprise it works fine and the SCART-HDMI converter showed "Scart SV" as it should.

The picture is quite decent too:

and comparable to native s-video direct to my Bravia:

I must have done something dumb like not plug my cable in properly! :p

Good news folks, using a scart plug adapter (http://i.ebayimg.com/00/s/MTAwMFgxMDAw/$T2eC16JHJG8E9nyfmIDKBP+52H4iO!~~60_35.JPG) it most definitely converts composite and s-video to Hdmi along with the audio.

I tested the s-video with my TiVo and got a superb picture, really quite impressive considering and it shows "scart SV" via the osd.

The c64 via composite also produced a surprisingly nice picture considering, like really really nice, was hard to believe it was composite, only the softness and bit of colour bleed gave it away but it was a much better pic than my Bravia TV produces when fed the same signal!

Bad news tho, using my very cheap c64 s-video cable it doesn't recognise the signal as s-video (shows "scart av" on the osd) and as a result produces a truly aweful aweful picture!

I checked my S-Video cable and it does have the 300ohm resistor but my c64 still wont work properly with my SCART-HDMI Converter - seems Commodore video is just too far out of spec for it to recognize it properly. :(

c64 Composite does work tho and looks surprisingly good.


Just got mine all set up.  Tried it with my A1200 and 500 on our big Panasonic Plasma in the lounge. Amazing picture. Crisp clear and flicker fixed in interlaced mode too.  Beautiful.  Thanks for the tip djos.
Haven't tried the C64 yet and I've gotta get another HDMI cable to use my BenQ monitor. Pretty sure it will work on that too.

Apart from the shocking clarity the best bit is the way it handles dithering or gouraud shading.  Most video converters have big trouble with that especially the "silver" look. Special!

On High res interlaced PAL there is a slight shimmer of drop down menu items for a split second but if you didn't know it wasn't supposed to happen you might think it was an effect. It could just be an artefact of the upscaling. Also when jumping from low res back to high res the same split second shimmer is evident but barely noticeable. Almost like a settling.
I'm pointing out tiny insignificant blemishes on what I think is the best Amiga display I've seen since vanilla 1084.  I have / used 2320(Amber), Picasso II, Retina Z3 and they either suffered from shading artefacts or the washout look. This is crystal and very 1084ish.

I ran through a few WHDload games in front of the big screen last night; Super Cars, Superfrog, Loopz, Historyline(sucked in for too long there!)  Had to sit a good 3 metres back from the screen but the contrast was great and the display rock steady.  Might have something to do with the Panasonic VT30 1080p screen though. :)

Once I pick up another HDMI cable I try out my cheapy BENQ Monitor and let you know if the result is the same.

Cheers.

Is anyone using one of this? Any comments or suggestions? What else would be needed to use with A1200?

this thing does work, but sometimes gets confused about interlaced mode. Its like it gets every other scanline reversed like 50% of the time. I put a push button on the power cord to reset it when it got confused in interlaced mode.  

It shows a lot of banding and I was generally not very happy with it.

That being said, its better than nothing and it does look better than composite.

Good to hear it's working great for you too mate, my only beef is the lack of compliance with the SCART pin8 signalling and it stretching 4:3 to 16:9 as a result as my Bravia doesnt allow me to squash 16:9 720p/1080p content back to 4:3 AR!

I've calibrated my display for it too by hooking up a BD player to the HDMI pass-thru and running thru my spears & munsil calibration disc. This is worth doing as the SCART-HDMI converter tends to turn up the colour saturation a little bit (and im anal about PQ).

Your Panny VT30 is a superb screen so im not surprised it works well for you - does it have an "aspect" or "zoom" button that allows you to fix the aspect ratio?

There's a bit of black bordering on normal games, nothing intrusive. Using overscan on workbench I was able to get quite good coverage.  The RHS has a bit of unusable border.  4:3 Aspect was distracting.  Too much side space. Geometric games like Loopz can look a bit stretched on 16:9.  4:3 Zoom was like playing Doom, too blocky.

The upscaler couldn't handle my normal A1200 workbench screen which is..I've forgotten...  Anyway it was a 32khz mode 800 x 600 which looks great MUI. It actually came up double screen perhaps because my Panasonic thought it was 3D, dunno.

The colour looked great.  Especially when I'm so used to the washed out look of most Amiga video expansion options.

yeah I found the image is slightly shifted to the right of screen too but just so pleased with the results I dont care. :D

Tested on my BenQ.  Works fine.  A little more washed out than the Panasonic but still nice. Still has the slight menu flicker on opening so its an artefact of the SCART - HDMI converter.  Still it's good to switch from my Amiga 1200 to PC with a touch of the Monitor input button. Just like my A4000.

Im seriously considering buying a new 24" IPS LCD for my Mac Mini and moving my 21" Samsung LCD to my Amiga 1200 along with a 2nd SCART-HDMI converter - beats the hell out of my GBS-8220 and my Samsung lets me correct the aspect ratio back to 4:3.

ok I bought this 720/1080p HDMI converter and would like to review it for the french magazine AmigaPower.
is there something (game and /or util) that would qualify for that, and prove (or not) that it is great value for money compared to others options ?

The only issue with the HDMI converter is moving items look soft due to the deinterlacing method used.

Aside from that it's great as it supports 50 & 60hz. Your tv will need to support forcing 720p or 1080p into 4:3 mode tho as the converter ignores the Scart aspect ratio signals.

Btw there is one better unit IMO, it's form the same mob and converts scart-rgb to component video - either 576i 50hz or 480i 60hz.

a new one ? I could not find it on the items list from earlydepot (ebay).

I also notice the blur effect when it is moving on screen (try Hybris).
no problem with the display : my TV is 720/1080p compatible and I can change the display at will (16/9 or 4/3).
my only grief is that the info window does not stay for long and that you have to hit those buttons twice (one to activate, one to change).
