Thanks very much for posting your further tests and the successful results.
That will be a big help for others with similar problems.

Could you restate what does work?

I get the impression that only the lower color depth works (16 bit rather
than 32 bit). Is this correct? I should have asked you to describe 'messy'
better. Evidently the problem is with bandwidth rather than sync, and your
'messy' meant fuzzy and ghosty with strange contrast rather than crawling
streaks and a disorganized image. Is this a correct statement?

| Let me summarize up the story here (hope it's not too lengthy ;>)
|
| 1. At 29-Nov-05, I bought a 2nd hand 10" monitor (Topcon VS-10S) from
| shop. I intended to use it to connect my PII PC (P2L97
|
| motherboard) w/ NVIDIA RIVA TNT display card & XP Professional
| installed.
|
| 2. I could get normal VGA display from 10" monitor connected to PII PC.
|
| Tested WinXP display setting: 640x480, 32 bit color, 60Hz vert. freq.,
| PnP monitor (normal output)
| Tested WinXP display setting: 800x600, 32 bit color, 60Hz vert. freq.,
| PnP monitor (messy output)
|
| 3. Display output was turned into messy as I change the display setting
| to value other than 640x480, others kept unchanged.
|
| 4. First posted message here.
|
| 5. At 30-Nov-05, I connected the 10" monitor to my Althon PC
| (MP-7VIP-DR-LE motherboard) w/ winFast S610 AGP display card
|
| (called it NVIDIA GeForce 2DDR in previous messages) w/ ME & XP
| Professional installed in C: & D: respectively. Display
|
| driver used that available from XP.
|
| 6. Replied messages here.
|
| 7. I booted the Althon PC into XP. Then I tried changed display setting
| from 1024x768 to 800x600, display output turned into
|
| a mess.
|
| Tested WinXP display setting: 800x600, 32 bit color, 60Hz vert. freq.,
| PnP monitor (messy output)
| Tested WinXP display setting: 800x600, 32 bit color, 70Hz vert. freq.,
| PnP monitor (messy output)
| Tested WinXP display setting: 800x600, 32 bit color, 72Hz vert. freq.,
| PnP monitor (messy output)
| Tested WinXP display setting: 800x600, 32 bit color, 75Hz vert. freq.,
| PnP monitor (messy output)
|
| Note: above setting was changed by connecting PC with my Samsung
| SyncMaster 151B LCD monitor then swapped connection to 10"
|
| monitor after setting effective.
|
| During the test, I've called the shop on phone, they reminded me to
| make sure vert. freq. was at 60Hz.
|
| 8. Discussed case with Phil here.
|
| 9. At 1-Nov-05, I tried connect the 10" monitor to my 3rd PC, also a
| PII PC (P2L97 motherboard) w/ WinFast 3D L2300 AGP
|
| display card w/ XP Home installed. Display driver used that available
| from XP.
|
| 10. I tested below WinXP display settings, tests failed.
|
| Tested WinXP display setting: 800x600, 32 bit color, 60Hz vert. freq.,
| PnP monitor (messy output)
| Tested WinXP display setting: 800x600, 32 bit color, 70Hz vert. freq.,
| PnP monitor (messy output)
| Tested WinXP display setting: 800x600, 32 bit color, 72Hz vert. freq.,
| PnP monitor (messy output)
| Tested WinXP display setting: 800x600, 32 bit color, 75Hz vert. freq.,
| PnP monitor (messy output)
|
| Note: this PC was connected to NEC MultiSync V520 while changing
| display setting.
|
| 11. I went to the shop again by 1-Nov-05 evening, the staff tested my
| 10" monitor at their PC, no problem at all at 800x600,
|
| 60Hz vert. freq.
|
| I checked from XP display properties, they used Matrox Millennium 550G
| display card with dual display output, one connected
|
| to original Philips 105S monitor, another to this 10" monitor.
|
| I asked them why will that happened. They had no idea. One guy
| suggested me re-installed display driver (may be it's not
|
| update). What a suggestion !!!
|
| Finally they gave me another Topcon 10" monitor (called it NEW 10" MON
| below).
|
| 12. I tested the NEW 10" MON at my Althon PC with below display
| setting:
|
| 800x600, 32 bit color, 60Hz vert. freq., PnP monitor (messy output)
|
| 13. Suddenly, I remembered this PC also has ME installed. So I booted
| into ME & ran the tests again. Test failed with below
|
| settings:
|
| Tested WinME display setting: 800x600, 32 bit color, 60Hz vert. freq.,
| SyncMaster 151B monitor (messy output)
|
| 14. At this point, I almost gave up. I tried it again in my PII PC w/
| WinFast 3D L2300 display card using below setting:
|
| Tested WinXP display setting: 800x600, 16 bit color, 60Hz vert. freq.,
| PnP monitor (normal output)
|
| Bingo!
|
| 15. I changed the setting to 32 bit color, I could see normal output
| too!
|
| 16. I repeated the test again at Althon PC w/ XP booted. Firstly I used
| 800x600, 16 bit color, test successful. Then I
|
| changed the color to 32 bit with no problem.
|
| 17. While my PII PC w/ WinFast 3D L2300 display card still had 800x600,
| 32 bit color, 60Hz vert. freq., PnP monitor setting
|
| effective, I plugged the NEW 10" MON again to this PC. Bingo! Display
| output was normal, no need to change setting to 16 bit
|
| color first.
|
| 18. Test finished.
|
| Up to now, I still can't provide a explanation for this strange
| behaviour. I only know that lower the color depth first for
|
| this 10" monitor first is a safe setting.
|
| PS: I'm not sure if I had tested WinXP display setting: 800x600, 16 bit
| color, 60Hz vert. freq., PnP monitor (messy output) at step 7. But even
| if I did, I'd tested it after using 32 bit color setting.
