LCD monitor with 50 Hz pal games

PiCiJi · 14 December 2009, 21:36

Im a still using a CRT monitor. So it's time for a LCD. On my CRT I lower the refresh rate to 50 Hz to enjoy smooth scrolling with pal games. But I wonder if it's possible to play pal games with smooth scrolling on a LCD Monitor. I always read from fixed refresh rates on LCD's (60 Hz)
So is there a possibility to emulate pal games smoothly on a LCD?

alexh · 14 December 2009, 22:11

If you buy an LCDTV instead of a standard PC LCD and use the SCART input then yes. Otherwise you'd have to be very lucky to find an LCD that syncs to 50Hz.

Do not forget the other two problems with LCD's

1) They do not work with Amiga's because they do not sync to 15KHz horizontal refresh so you need a scandoubler (built in for LCDTV's)
2) Their native resolution is usually many times PAL and inputting a PAL resolution signal introduces scaling artifacts.

The Indivision AGA & ECS scandoublers scan rate convert PAL 50Hz screens to 60Hz for compatibility but the scrolling is not 100% smooth. Much better to use a tool to promote the PAL games to 60Hz. (i.e. WHDload)

PiCiJi · 14 December 2009, 22:53

thanks for the hints. Is the game speed unchanged by promoting a pal game to 60 Hz with WHDload? I mean, when I play pal games in 60 Hz with vsync the scrolling is smooth but video and audio are too fast.

Video : Of course not.
Audio : Depends on how the game was programmed, if it uses VBL interrupt then yes, if it used a timer then no.

Too fast for what? Most of the time you never notice.

Maren · 14 December 2009, 23:50

PAL application + 60hz monitor + vsync = incorrect speed but smooth scrolling.

PAL application + 60hz monitor - vsync = correct speed but bad scrolling.

It's either one or the other

NewDeli · 15 December 2009, 00:46

Why part with the CRT monitor, then ? I myself choose to display Workbench on a modern LCD and native mode screen (classic games, demos) on the CRT. Best Amiga emulation related decision I made in monthes !

Allen1 · 15 December 2009, 00:55

I am using a EIZO FlexScan L360 LCD monitor on my minimig and it works a treat, the other 2 LCD monitors I tried came up with out of range and one of them is brand new. Maybe a proper list of compatible monitors would be a good idea for anyone who needs a monitor as Ebay is probably the best place to get one if you are aware of what to look for.

NewDeli · 15 December 2009, 01:28

You maintain that list Allen1, and I'll print the stickers "Smooth WinUAE Scrolling guaranteed", I guess we're gonna become rich soon

.

all it would take is for users to say what monitor works with what hardware/Amiga they are running it from. Another monitor that works with a Minimig is a TUV 29J56G CRT mine is badged as RM, this monitor has built in stereo speakers and also a microphone and is dated 1997. The displayed area is smaller on this in comparison to the EIZO FlexScan L360 LCD monitor.

Maybe information like this would be useful to anyone buying a Minimig, I have not tried the monitors on any other Amigas as I use those on TV's with the scart lead I made plus I don't have a converter ie 23 pin to 15.

maybe i should give playing pal games in 60 Hz a second chance. In the past I have noticed it by few games for example Lionheart.

alexh · 15 December 2009, 19:21

Lionheart was designed to run at 60Hz wasn't it? I seem to remember it had that option in it's menus? I may be mistaken.

Plus it had it's own HD installer and so is not a WHDload game.

NewDeli · 15 December 2009, 19:44

Some WHDload games have a HD installer (sometimes it's not even "broken"), and the other way round, alexh.

@PiCiJi
You shouldn't notice any hiccup with games bearing a vertical scrolling.

Lionheart wasn't designed for 60Hz. But Flink was, it's switchable to 50/60Hz with the green CD32 pad button.

alexh · 15 December 2009, 21:13

My mistake Lionheart had interlace not 60Hz.

Just a shame it isn't 1600x1200 or I would have had one

Might look at a HP LP2065

ancalimon · 18 December 2009, 15:05

send emails to "for example" Samsung to produce monitors that can sync down to 15khz and 50hz. Maybe they value their customer that much.

I would immediately buy 2 or maybe 3 such monitors (20"?) if they ever produced one.

Lockon · 18 December 2009, 16:34

@Chain
There are a lot of crap, HP included, I agree.
(For instance, earlier model in this 19" range L1940T miss exactly those features)

However, this specific unit has following options under Main Menu/Image control:
Auto Adjustment, Horizontal Position, Vertical Position, Clock, Clock Phase

A cheap and cheerful way to try an LCD monitor is probably to look at the Ebay section where I have pointed out a Eizo FlexScan 360 just like mine which I am using with a Mininig. The auction ends tomorrow though and it is not my item but I thought it could be useful. It is UK only though by the looks of things.

Photon · 26 December 2009, 15:28

Grundig 100 Hz 32" CRT TV, and not just any old junk, but refurbished by a TV shop. Perfect 50Hz scrolling in Bubble'n'Squeak CD32. Really good picture even with RCA video (but don't worry, it has two SCARTs on the back!) Yay

Retro-Nerd · 26 December 2009, 15:30

Argh, a 100Hz TV? They never "scrolled" perfectly.

wlcina · 26 December 2009, 17:59

Could someone create a program, which will clearly show if the LCD is or is not scrolling smoothly ? for compare LCD's

Retro-Nerd · 26 December 2009, 18:15

You will never get a 100% perfect smooth 2D scrolling on LCD displays, no matter if it runs in 50Hz or not. Not unless the response time is nearly 0 ms.

Toni Wilen · 26 December 2009, 18:19

What does response time have to do with 50Hz vsync? CRTs have even worse "response" time

Anyway, it is not just the display but also drivers and OS that need to have 50Hz support = it is impossible to create test program that only tests the display.

Retro-Nerd · 26 December 2009, 18:23

Sorry, i meant real Amigas on LCDs. There is indeed an ugly motion blur, no doubt. The scrolling is fine, but the image isn't crytal clear.

NoX1911 · 26 December 2009, 19:28

For LCDs try 50Hz or 75Hz. 75Hz might be in range on most devices since 72Hz is for 3*24fps (hdtv).

Most PC tv-outs use heavy flicker filter that will downgrade the picture (blend fields) to prevent interlace bobbing. You can disable that on some cards. Deactivation is mandatory if you ask me.

If you have a good CRT (100Hz without postprocessor/deinterlacer) and an unprocessed tv-out signal (preferably on Y/C) you'll get a decent picture.

And the top of the cake if you want to watch a scroll like the one in Ruff'N'Tumble... Yikes! ...

Mequa · 17 July 2010, 09:05

How about 50Hz on PAL-region plasma TVs, for both a real and emulated Amiga? (Most modern plasmas/LCDs also have PC VGA connectors nowadays, in addition to HDMI, composite and SCART).

My brother has a 42" plasma, I might try my real A1200 on it via composite output, and test both PAL and NTSC modes and a few smooth scrolling games.
(Not sure what the image would look like though - his PlayStation 1 doesn't upscale terribly well on it.)

I have an old 40" Toshiba back-projection TV. My real A1200 works on it well in both PAL and NTSC modes, with much less blurry scrolling than on an LCD.
I can also use WinUAE on it via S-Video connector, running at 50Hz, however I have had a few sync problems with it (not just with WinUAE).

Retro-Nerd · 17 July 2010, 15:11

A real Amiga on a 50 Hz Plasma TV via analog Scart shows a kind of motion blur in scrolling games, it's probably the A/D conversion. The scrolling is smooth though. On the other side, WinUAE via HDMI on a 50Hz Plasma is perfect.

NoX1911 · 17 July 2010, 19:03

Plasmas have 'phosphor lag'. Most of the time green is too slow (green ghosting). Visible on black&white and consoles/computer gfx with high contrast to neighbor pixels.

The only technique coming close to crt would be laser.

Retro-Nerd · 17 July 2010, 19:08

Phosphor lag? And why is PC emulation perfect then? I can't see any issues there. Or is it caused due analog connection (Scart, S-Video etc.)?

NoX1911 · 17 July 2010, 19:14

PC emulation most likely isn't perfect at all. Maybe you just don't see it. Its less visible on natural material.

Phosphor lag is derived from different materials (chemical elements) for different plasma elements. Their "speed" is different (between red, green, blue segments). Some people deny that effect others are (subjective) immune. Its a highly controversial issue indeed. There are many videos on youtube.

Retro-Nerd · 17 July 2010, 19:21

Well, i can clearly see this kind of ghosting with my real Amiga, connected via RGB scart to a Plasma TV. PC Emulation (via HDMI) doesn't show it for sure, no ghosting at all. A sharp and clear image.

Toni Wilen · 17 July 2010, 19:24

Does it also appear in interlaced modes? Many digital (non-crt) displays work badly or strangely with non-interlaced analog video signals.

Retro-Nerd · 17 July 2010, 19:27

Do you mean me? I haven't tried interlaced stuff yet, only my old computer/consoles via Scart, lowres games.

NoX1911 · 17 July 2010, 19:28

Its not that TV makers don't know that issue (phosphor lag). There are most likely countermeasures (digital signal processing) fighting this whenever possible. Maybe it works quite well in your situation.

That rises questions about plasmas buffering frames like TFTs for overdrive creating input lag.

Retro-Nerd · 17 July 2010, 19:32

I notice motion blur on WinUAE+100Hz CRT or on a LCD monitor. If it's there too on a Plasma with HDMI, then i can't see it.

Toni Wilen · 27 August 2010, 18:13

I just bought true 120Hz LCD monitor (LG W2363D), some vsync testing notes (actually 100Hz vsync was the main reason for buying this..):

50Hz vsync emulation using 100Hz refresh rate works perfectly fine, no ghosting at all. Also for some reason GUI quality was crappy in 50Hz (which was surprising, I expected usual min 56Hz) but normal looking in 100Hz..

Some kind of windowed vsync is also possible by setting desktop to 100Hz (instead of 120Hz) mode, there will be glitches now and then but it looks much smoother than normal 60Hz desktop and 50Hz windowed emulation.

Note that >60Hz only works via dual-link DVI. HDMI does not (yet?) support HD >60Hz modes (stupid, isn't it?)

Also for some reason GUI quality was crappy in 50Hz (which was surprising, I expected usual min 56Hz) but normal looking in 100Hz.. Some kind of windowed vsync is also possible by setting desktop to 100Hz (instead of 120Hz) mode, there will be glitches now and then but it looks much smoother than normal 60Hz desktop and 50Hz windowed emulation. Note that >60Hz only works via dual-link DVI. HDMI does not (yet?) support HD >60Hz modes (stupid, isn't it?)
