Forcing 3D Vision @ 62Hz w/ non 3D monitor
Hi guys! I am the owner of wired 3DV glasses and (unfortunately) 60Hz monitor (ASUS VH228D). I read about dozen of comments here about people running 3D fine at even 60,5Hz. But NOBODY of them actually wrote how the hell they managed to do it. The largest resolution that provides the fastest frequency of 75HZ is 1440x900. 3D does not start. Creating custom resolution using GeForce Experience 1920*1080 makes possible to run the monitor up to 67Hz. The thing is that [b]I AM ABLE[/b] to run the monitor over 60,5Hz. When I try to run 3D Wizard, or just enable 3D without Wizard I get "Out of range" message on my monitor. I used to hack registry for every possible resolution "=1", rebooted - no luck. I checked if the lowest resolution in registry is actually supported by monitor itself - yes it is. Setting this resolution and trying to enable 3D gives me that "out of range" message. Can somebody post here how he/she managed to run 3D at 62Hz step-by-step?

You may start 3D Vision at 60 Hz on CRT monitors (i did it myself once, but it's almost impossible to play havin only 30 Hz per eye, it's pain), but LCD monitors is another story - it must support 3D in order to run 3D. Even if you have 120 Hz monitor with no 3D support you cannot run 3D. Not sure this trick you described is possible with LCD non 3D monitors really. But anyway may be someone else on this forum can help..

wired 3DV glasses = 3D Vision 1? If i am right using 3D V1 allowed any 120 Monitor to run shuttered, or is it a limitation in newer drivers also valid for v1? Anyway i believe your best bet is to use a driver from another monitor allowing the same resolution/freq as your's and more (yet use 60Hz only to have at least 2x30Hz, you can also use 62 but then have to add a changed nvidia driver dll, take a look [url=https://forums.geforce.com/default/topic/705010/3d-vision/any-reason-the-optoma-eh500-couldn-t-do-1080p-60hz-3d-over-displayport-/post/4199905/#4199905]here[/url]).

Hold on a sec! I just have noticed, that my monitor is not recognized by OS: "generic non-pnp monitor". Is that an issue? I am also using DVI-VGA dongle to hook up 560GTX and the monitor. Sorry for not mentioning this. Maybe this is a problem??

The people who've gotten 3D to run at 60hz are using passive 3D displays. There's no hack to get it working on a normal LCD display, unfortunately.

Pirate, what is that thing passive display?

A screen that uses polarised filters instead of shuttering. You can google it if you want more information.

[quote="Pirateguybrush"]A screen that uses polarised filters instead of shuttering. You can google it if you want more information.[/quote] I see, thank you. No need to google, i have some undertsnding of polarized technology =). Just never heard before it calls passive monitor.

@MastersWRC The generic driver shouldn't be an issue. At least not when you test standard-resolutions and using nvidia cp to change custom resolutions (and not for the monitor - he's the one with "Out of Sync" right?). On that DVI-VGA Adapter: might be the reason, either i don't know if it is. Btw. can you make some screenshots of the nvidia "3D Vision Setup Asisstant" as i'd like to know what nvidia recognized here. The best option would be to sell the Monitor, get a new one that supports 120/144Hz and 3DV2 (i mean D-Sub, srsly? You DO have quality loss if a digital signal is converted to analog(lossy), transfared over a i guess cheep cable (and due to that/analog also lossy), and coverted back to digital(lossy #3)) The other option is to try out a few monitor drivers (in case you can't see anything anymore, boot into failsafe mode and delete the faulty driver in driver manager - then generic one will be used again. Or you make systemrestorepoints/backups). You might also want to take a look into: https://forums.geforce.com/default/topic/778329/3d-vision/dsr-with-3dtv-play/1/ @Pirateguybrush - the main topic about "not lower than 100Hz" is cause of the emitter, not? But the old wired 3DV1 glasses should theoretically allow any frequency.
