I though that was just made for fun... It is not as good as the vampire itself. I'm not interested by this home made box that could be one more DIY enclosure  project.

  @Gunnar - what resolution is that!?!? 1920x1080?
 

 
  Its 1600x1200
 
  But please note Vampire officially supports up to 1280x720.

Would say its best to support Amiga resolutions of 5:4 aspect ratio, or 1280x1024 for workbench, and 320x256 or 640x512 for games. Doing pixel art is easier when pixels are approximately square. I don't like these 1920x1080 resolutions at least or 1280x720. Good maybe for watching HD/FULL HD videos on fullscreen but not for desktop in general.

Nobody is forcing you to use it. They're providing SOMETHING which is better than nothing for folks who won't care.

Cases are a pretty personal preference thing. You can always put it in something else if you don't like what they give you...

V4 support all kind of resolutions.
But 16:9 resolutions make a lot sense today - as all TV sold are this format.

Yes, but I'm using old CRTs as displays for Amiga, which need correct aspect ratio to have square pixels. Newer displays cause too much probs with not being capable of displaying 50 Hz correctly or the response time is poor. Both means trouble for scrolling smoothness.

Could it be that you post in the wrong thread?
This thread is about the V4-SA.
The VA-SA is a brand new AMIGA.
People that get the V4 will of course also use a new TVs.

We have totally different experiences.
On V4 AMIGA games run just fine and butterly smooth both in 50 Hz and in 60Hz .

This was just an old problem that I mentioned - most modern LCDs can only handle 60 Hz, so they will need to interpolate somehow a 50 Hz signal. Most games/demos are made with a 50 Hz update rate on the Amiga. This is indeed not so much related to V4-SA, I just mention that some users prefer to use old CRTs. These need a VGA connector.

Not true.
All modern TVs in Europe perfectly support 50Hz.
But you have to give them a "proper" input signal.

Maybe your bad experience is based on using bad input signals.

European TVs, yes. What about North American TVs? Have North American TV's been tested with V2 and V4SA? Please don't forget about us on the other side of the pond.

I've used my PAL A1200 (no Vampire) on one NA HDTV and it worked at 50Hz. Soon, i'll test a monitor. That's not a thorough testing regime.

My NA Vizio TV worked at 50 Hz but monitors may need an upscalar from a lower resolution to hit higher scan rates.

Every Monitor or TV worldwide which has the H-D-M-I Logo
has to be able to correctly show PAL @50 and NTSC@60 Hz
This is per definition of the standard.

This means the every TV will show the original Amiga Display Formats correctly - if you give it proper input signals.

If any AMIGA has display issues then its the fault of the input signal - e.g. the Scandoubler or flickerfixer card you use.

Actually there is a well-known number of H D M I tvs in North America that have problems displaying 50hz PAL .. this cropped up with the Ultimate 64 (also FPGA Cyclone5) was released, initially the firmware only did PAL video modes and a number of people reported problems with display .. Seems a number of vendors did not enable or bother to add PAL/50 support to their models sold in the USA/NA.

To make this clear, there is a very clear "rule" for any vendor to sell something with the H-D-M-I label.
The rule states: "The device has to support PAL 50Hz"
If it does NOT then it clearly not allowed to be sold as "H-D-M-I" device and you can surely ask your money back.

Yes maybe some TV are "fakes" ?
on the other hand also the U64 could have made some signal mistake.

We can not find out from here.
But one thing is clear, in AMIGA market are some GFX output devices - like indivision.
And some of those not correctly put out PAL@50 signals - this means these devices cause the problem mentioned - not the TV.

perhaps I could try to do a test distribution based on magellan with just desktop (magellan) integrated

Olaf how does WHDLOAD work on AROS?

Having all the old DEMOS on the WB easy to load and run will be liked by many users.

whdload works perfectly

you just need to integrate the original roms in it (f.e. from amigaforever)

or you use the aros roms in it

then many programs work but not all

unfortunately it seems I am wrong
 
  version of aros nightly from 30.5. works perfectly with whdload, version of 16.9. freezes
 
  no clue what they have changed

I tested it with wanderer and no additions

:-(

That is the main problem with aros, what works with one branch negative affect another branch

Its good that AROS is developed.
And mistakes are human and will happen.

I see this progress as benefit and I'm sure more people testing this and more helping hands can help here too.
