  • I've been having a lot of trouble with getting good results from VGA monitors on my TC64. I've tried several LCDs and a CRT and I'm still getting sync/mode problems. Is there any way to make fine adjustments of the modes?

  • No, the Chameleon does not allow setting these parameters; we only have the presets that the menu offers. Please choose one of them as a basis and switch off V-Sync option for starters, as that will cause trouble with many monitors (only high-end gaming monitors support V-Sync).

  • By sync problems I meant the iamge on the monitors being too far left or right (I think this is "phase") and by V-Sync I meant Vertical sync. I think you're confusing my use of "V-Sync" with G-Sync or FreeSync. I've got best results with a Phillips 150S4 and a Samsung SyncMaster 940MW.

    I'd call this "positioning", as "phase" is mostly used for the exact point in time where a single pixel is sampled. However, you should be able to move the picture left/right using the monitor's functions. The Chameleon outputs standard screen modes with Vesa timings, so any monitor should be able to show the whole picture. Granted, some wide-screen types will add black bars, but that's just the nature of displaying a 4:3 picture on 16:9 monitors.

    and by V-Sync I meant Vertical sync.

    Interesting that you're explaining what you meant by "V-Sync" where you didn't even use this term in your original posting :-)

    Actually, I'm not. When popular computer press started covering the topic of syncing the screen with the graphics card, they were using "V-Sync" as the name for the monitor's frame buffer to be filled in sync with the display data coming in. I was really confused, as the signal name for one of the signals on the hardware interface is also called "V-Sync". However, I found that popular press and gaming web sites are using "V-Sync" as a general term for what graphics card manufacturers call "Freesync" or "G-Sync" in order to have their proprietary name, because some marketing guy decided to do so.

    So apart from marketing terminology, we're talking about the same thing: FreeSync, G-Sync and V-Sync mean all the same, and it's generally a good thing for our task, which is "tearing- and jitter-free output".


    I was just told that G-Sync and FreeSync are completely different things, only in a similar family of technologies to get rid of tearing and jittering. So I better stick to what I do best, and that's hardware, not marketing terms :-)
