I recently got a new lcd tv and want to connect my efika to it. How do I safely change change the current settings from the 1024x768x60 to its 1920x1080x60? I hooked it up, but the current setting was slightly blurred on the right side , and you know that's going to irritated me to no end, so some help please before I mess something up. I'm don't like being on the macmini, if I can be on my efika with morphos2.2

"but the current setting was slightly blurred on the right side" - Odd, looks like a broken one :). If it isn't detected automatically via DDC you have to edit modes in "System->Settings->Monitors". Press Edit button and define your monitor. Details about monitor should be included in its manual. In next step add new modes, you can test every screenmode and modify it to suit you. It's quite safe, no need to worry.

well, sometimes helpt just to press the 'i' or 'a' button on the monitor or 'auto'... atleast it seams, all my lcd's works great with it...

bye, MarK.

Thanks guys, I jjusust went to the ambientmui under settings and did it there. Kind of hard on the eyes, so I adjusted the previous setting and got rid of the haze works fine now

Hi guys, I'm picking this thread up because I have a weird problem with my shiny new Blusens H96 26" LCD TV monitor. I was a happy ignorant chap, thinking this cool flat screens were as tolerant as oldie tube monsters.

Problem: No image is shown, nor SmartFirmware, nor my regular 1024 x 768 at 85 hz ambient desktop, nor a new monitor mode I made up, which was 1680 x 1050, and very close to the recommended 60 Hz for LCDs.

My great Targa Visionary huge 21" CRT monitor (found in the thrash!) copes with everything I throw at it (even the 1680 x 1050), but the new Blusens doesn't. Can it be a broken VGA cable? I guess not, because the Blusens is recognized by MorphOS via DDC (while the old Targa isn't, perhaps it doesn't do DDC at all).

By the way, MorphOS sees just up to 1366 x 768, but the manual says it's 1680 x 1050... while the web page says otherwise. Is MorphOS revelaing that I've been conned?

I still have to check a second VGA cable, which does have all the pins (unlike the one I have now, which misses one). Also I have to check with... shock... horror... a "regular computer", a laptop PC with VGA output. By the way, the new monitor doesn't have an "auto" button. It does have DVI connector, just like my Radeon 9250 has. But I don't have that cable. Can it guarantee a solution, or it isn't that different from regular VGA?

@jcmarcos :

Drop your VGA cable and replace it with a true DVI cable.

I tried to hook my efika with radeon 9250 DVI ouput + DVI to VGA cable, it didn't worked. Switching to full DVI (radeon dvi -> lcd dvi) worked straight.

A DVI cable worth little. Check ebay for example.

Thanks for the tip, Tcheko, I was already thinking about that, and will buy a DVI cable this afternoon. I've never had any computer or monitor with DVI connector. Is it true that it also carries audio? Is the signal also analog in the end?
I have to say that I once tried a horrid 15" monitor that did work. It had its own VGA cable, though.

Depends.

There is three kind of DVI cable afaik.

DVI-I, DVI-D & DVI-A.

D for digitial
A for analog (DVI->VGA adapters...)
I for integrated (both A & D).

Most recent computer LCD screen have only DVI-D.

I am no expert on the subject but you can certainly catch some more advice with wikipedia on the subject.

Here is the revelant wikipedia link on this subject : http://en.wikipedia.org/wiki/Digital_Visual_Interface

Also, it is possible to link DVI to/from HDMI -> hook your HDMI LCD TV to your DVI computer video output.

I did once for my Efika. It works really nice :)

Finally, I got it working: I bought a DVI cable, but also got a different VGA cable, which I tried first with the portable PC I also got for testing: No problem, the new VGA cable (which looked weaker than the previous, that had a pin less) worked fine.

So I plugged this new VGA cable to the Pegasos, and my new monitor works! CyberGraphX, via DCC detects a "Blusens LCD" monitor, and creates modes up to 1360 x 768, the one I'm using (mora of that later).

The downside is that I can't see SmartFirmware screen at all: The monitor says it's an invalid mode (really? 640 x 480 is "weird"?). Doh.

I think I remember there was some key to press in SmartFirmware, that somehow changed the screen, but it's only about the size of the text, not the display mode, right?

Now, for all you to laugh at me: After this relative success, I decided that I would try with my shiny new DVI cable, just for the sake of it, as I've already bought it in a hurry, and wasn't really needed. It would probably only work with analog signals, so it's not any better that the VGA cable.

So I opened the plastic shell, took the cable out, plugged it into the Radeon 9250 DVI port, and THEN (!) realized that my brand new monitor does NOT have a DVI port at all, of course. It has HDMI, just like any other modern monitor/TV.

Can one be any more stupid?

Back to more serious matters, does anyone here actually got a 1680 x 1050 mode out of the Radeon 9250? I played with obscene "bandwidth" values, trying to fool CyberGraphX (of course, I was only fooling out myself) to reach this pornographic resolution that the LCD panel has, but to no avail: While there was no problem setting the 1680 width, the height never got past 786 or some figure like that.

I hope someone here cares about helping such a dumb guy... Like I said before, perhaps I'm too old, and should not fuss around with modern, flat video technologies...

Sorry to insist, but it seems my long posts scare people away (please read it, if you wish)...

Does anyone here actually got a 1680 x 1050 mode out of the Radeon 9250? I had 1600 x 1200 in my previous "Monitor 85 Khz", so I thought it was possible.

well, on my radeon 9200 pro it looks like here.

bye, MarK.

How nice Mark! I guess that's exactly what I need. I'll print your screenshot, and will try at home. Thankyou!

jcmarcos, use a DVI to HDMI adapter.

Quote:

Yes, I guess that would give use to my new DVI cable. But, as I believe that only analog signals would be used, would it work? If I had a spare one over here, I would give it a try. I don't want to waste any more money...

Quote:

Maybe you could tell us why you believe that?

Quote:

Because I've never read anything about CyberGraphX drivers generating digital signals, being a software born before digital video output existed.
I don't think digital signals come out by themselves, but I'd be very grateful to learn otherwise.
Also, I know from people that see positively no change in the image quality between VGA and DVI connections, so that should prove that the signal is analog in both cases.

Quote:

Luckily CGX was updated along with the rest of MorphOS, I've been using DVI out for years here, it's mentioned here and probably elsewhere. In 1.4 there was a tooltype that needed to be set, though IIRC it was enabled by default in 1.4.5 at least.

Or it proves something about these people, the difference is quite clear here.

@ jcmarcos

Quote:

It can prove a lot of things, including that these people own monitors with such a horrible picture quality that they cannot even tell the difference between video input via VGA and DVI

On a more serious note, there is a very noticable difference between VGA and DVI input when I use my monitor (with a Pegasos or other machine, does not matter).

OK, so my next addition will be a DVI to HDMI adapter. I have one question, though: In CyberGraphX monitor settings, you actually tell the software how to modulate the analog signal that will be fed to the monitor. But, if the signal is digital, wouldn't all these settings be out of question?
I bet now I've made completely clear that I have no idea about digital video signals!

Thanks everybody!

It's been there for 6 years now :-)

DVI does not mean automatically digital output.

There are also analog signals on DVI.

Read DVI-A on Wiki

I have no chance to check it because of missing DVI-port on my LCD-Monitor.

Yes, of course. But in MorphOS case it's been (also?) DVI-D from 1.4 on.

On a more serious note, there is a very noticable difference between VGA and DVI input when I use my monitor (with a Pegasos or other machine, does not matter).

There are two factors of difference between DVI and VGA output quality:

1. The difference is better visible on bigger monitors. On 15" it may look the same, on 19" or 20" the difference may be easy to notice.

2. VGA quality strongly depends on gfx board. For 20 or so cards I have tested, ATi chipsets produce much better VGA output than nVidia ones. For example R9200SE gives excellent VGA picture on 19" panel (compared with DVI of the same card and the same monitor). On the same monitor GeForce 2 output is pathetic blur. More detailed investigations revealed that most nVidia cards generate VGA output with pixel clock frequency changing slightly along a scanline. Then pixel clock regenerator in the monitor cannot phase-lock to pixels precisely. The result is blur in some parts of every horizontal line. For DVI this pixelclock detuning has no meaning as pixelclock signal is delivered along with RGB signals.

@jcmarcos,

At the end of march of this year I bought to IMM Informatique in Luxemburg a wide flat monitor, lg flatron w2452tx, ratio 16/10. Both dvi and vga cables are provided with the monitor. At the beginnings I plugged it to my graphic card radeon 9250 with the vga cable. A few times later I gave a try to dvi cable. The monitor is used at its native resolution 1920x1200 pixels at 60 hz.If I switch between the input source, analog or digital one I see the difference, the display is smooth in digital mode. Finally I removed the vga cable because I do not have any other computer than my pegasos 2.

Hi all,

to me there is a big big difference between DVI and VGA. Really, I think DVI is a must if one works on MorphOS
8 hours per day. I use a resolution of 1600x1200 at 60 Hz. Unfortunately my newer Graphic cards, the 9250 Pro with 256 MB of RAM seem not to work with this resolution on DVI, only up to 1280x1024 works! So I had to change back to the 9000 Pro Graphic cards with 128 MB of RAM which works fine with 1600x1200. The only thing is that I have several defective 9000 cards, so hopefully this bug in the MorphOS monitor driver (if it is a bug) will be fixed soon as DVI is really important.

Here are some topics about this problem:
