Does V-Sync work on monitors?


I'm using WinUAE v0.8.22R1, Windows XPSP1, and v30.82 of the Detonator drivers for my Geforce2 MX card.

My problem is that I can't get V-Sync to work with my monitor. (A 17inch mitsubishi Diamond Scan 70).

I'm trying to play the game TechnoCop, but the horizontal tearing of the screen is extremely annoying, making the game almost unplayable.

I thought that V-Sync would solve the problem, but it makes absolutely no difference to activate/deactivate it. The annoying horizontal tearing is always present (I've tried to activate/deactivate V-sync with the following refresh rates: 50, 60, 70, 85 and 100 Hz, but they all suffer exactly the same tearing effect).

Does V-Sync only work on TV screens? Will there be support for PC monitors in the future?

Thank you very much.
Kind regards.

Try using 720x576x16 @50Hz, with VSync and centering OFF.
If u don't already have this res available you may need to create it using Powerstrip or something similar. For me this gives a perfect res and flawless scrolling with no tearing whatsoever...
ps. Don't forget Technocop has rather poor scrolling anyway

Vsync on/off does not cause or prevent tearing because WinUAE uses triple buffering (=prevents tearing) in full screen modes.

Question Could it be the game's fault?

Thank you very much for your replies.

Now I understand that V-sync has no effect on my monitor when using full screen modes.

But, what is causing this tearing effect then??

I have taken a screenshot, please take a look at it and tell me your opinion.

Thanks a lot.

It still is strange that he could snapshot the "crack" in the screen.... when you have a really shitty card that cannot scroll to save its momma, you can see shit like this happening but you cant snapshot it!

Hello people,

I will list here my system configuration, although I hope it's not my cumputer's fault, but who knows:

Intel Celeron at 633 MHz (not overclocked)
ASUS CUSL2-C Mainboard (intel 815ep chipset)
256 MB SDRAM PC133
Guillemot Hercules 3D Prophet II MX 32MB AGP (bios v3.11.00.18)
SoundBlaster Live! Value
NIC Ovislink (Realtek 8139A chip)
Hauppauge WinTV-Nova satellite DVB card

nVidia generic detonator drivers v30.82

The screenshot was captured by pressing the "Print Screen" key and then pasting the result in Microsoft Paint (it came preinstalled with the operating system) and saving as a .PNG file.

All the screenshots I've taken show exactly the same tearing effect that it's present while playing. The screen is always torn in half during the game, it's really annoying!

Could it be a problem related to my graphics card and/or drivers?

Thanks a million.
Best regards.
