- Do any appear in your screenmode requesters? Perhaps you have to do a bit of
- editing in CyberMode. I've included my monitorsettings at the end of this

- It's always a good idea to have the latest drivers. Mine are:

- Yes. Your chipram will mostly be left alone, except by programs that
- spesifically allocate it (i.e. for Intuition Image structures)
-
- To calculate the RAM needed for a CGraphX screen, you can generally do this:
-
- 8 bit: Width*Height
- 24 bit: Width*Height*3
-

- No, my guess is that you have the pixel clock set too high.

- Correct. But DPaint doesn't work on CGraphX screens :)
-
-

- They are used for exactly that; alpha channels. So far I haven't seen any
- programs that use this feature.
-

- No, the extra 2Mb is used to get higher and deeper displays.
-

-
-
- > other than checking out the chips.
- No, and so far CGraphX doesn't support this, so you have no way, short of
- calculating the memory used for you screens, to find out how much RAM is left
- on your CGraphX supported card.
-
-

- Try my monitorsettings.
-
-

- No, every screen is buffered in FastMem. The additional memory on your card
- can as I said only be used for larger/deeper displays.
-
-

- True.
-
-
- >3. PASS-THROUGH:
- > - What is meant by "pass-through" Amiga Signal, how does it exactly work?
- It does just that, pass a native Amiga display through the card when one is
- used.
-
-

- Yep, the cable is used for this.
-
-

- On my Sony 17sf, I get a black screen, because it doesn't try to display
- resolutions it knows it doesn't support. If your monitor doesn't have this
- feature, my guess is that you would see a truly FUBAR display ;)
-
-
- > - What does the ScanDoubler/FlickerFixer do together with the CV64?
- Which Scandoubler? You mean _a_ ScanDoubler? Well, if you connect one to your
- Amiga and pass its display through your CyberVision, whenever your Amiga tried
- to display a non-VGA mode, it would first be scandoubled (VGA'd), then passed
- through your CyberVision, and finally be displayed in perfect VGA on your
- monitor. (Atleast that's what is supposed to happen :)
-
-
- >5. SOFTWARE/UPDATES/SUPPORT/DRIVERS/BENCHMARKS:

- See above. It's all available on Aminet. In gfx/board, I think.
-
-

- > their BBS (are they preparing a Web Page/FTP Site for support/updates?).
- You can either call the BBS, pay your dealer, or get them from Aminet. The
- latter is always the fastest and cheapest method.
-
-

- > Monitor File?
- The only hardware spesific software is the monitor driver. The libraries are
- used for all monitor drivers, and you can safely copy newer libraries from
- Aminet or a friend and install them on your machine.
-
-
- > - Is there somewhere a list available that lists the programs that
- > support the CV64 directly (through drivers?), the programs that work
- Any program that uses the DisplayDatabase (i.e. has a screenmode requester)
- should work. Exceptions are i.e. DPaint and Brilliance, both of which bypass
- the OS graphics library calls and do their own stuff instead.
-
-
- > - Which Benchmark programs can you use to test the speed of the board?
- In my experience IntuiSpeed is the most used program to test graphics board
- speeds.
-
-

- > you set these env variables after installation?
- Edit them in an ASCII editor or get CyberPrefs.
-
-

- > installation time?
- Perhaps you have an old installation archive. Get the latest update from
- Aminet.
-
-
- >6. PLANAR-TO-CHUNKY:
- > - Planar-To-Chunky-Pixel Converter in Hardware, what exactly is this
- > used for?
- The S3 chip used in the CyberVision is a chunky graphics chip. It requires
- it's data to be in chunky format. The amiga uses planar graphics data. It is
- used to convert planar data to chunky so it can be displayed and used on your
- graphics card. It is generally faster than using the CPU to convert between
- planar and chunky.
-
-
- > - In the prototype review it was mentioned that the software did not
- > support this Converter yet, as of which software version is it
- > supported?
- It has been supported in every release version that I know of. Get the latest
- update from Aminet.
-
-
- >7. EXPANDABILITY:
- > - In their german ads they mentioned Digital VideoBus for possible
- > expansions and a Connector for Video-Encoder with FBAS/S-VHS Output,
- > what/where are they?
- Never seen any products that use this feature yet.
-
-
- >8. MONITORS:
- > - What does the on-board electronic Monitor switcher do?
- Switch between native Amiga- and CGraphX displays. When you switch from a
- CGraphX display to a native Amiga display, your CyberVision automatically
- senses this, and displays the native Amiga display.

- Well, I've always liked my Sony 17sf. You can read my review of it. Available
- on Aminet as:
