I've got a VT60 Plasma. It is capable of 3D and thus should somehow allow 120 Hz inputs (60Hz 3D).

Is there anyway to force this somehow using a GTX 580?

I have tried adding a custom resolution via Nvidia CP with 1080p @ 120 Hz, and 720p @ 120 Hz. I haven't tried to fiddle with the timings though, as I have no idea what could actually help.

As far as i know on Nvidia the monitor/hdtv needs to be "3D vision ready" and i cannot find that VT60 plasma on their list.

I can't really remember everything but you use 3DTV Play (which is now free if you have 3D Vision). I think the problem is bandwidth over HDMI at 1080p @120hz...?

Ryzen 5 5600, ASUS ROG STRIX B550-F GAMING WIFI II, Corsair Vengeance RGB RT 32GB 3600MHz C16, MSI RTX 5070 Ti Ventus 3X OC , Corsair RMx Series RM750x. AOC AGON AG324UX - 4K 144Hz 1ms

Due to your advice, I tried the trial version of 3DTV play, but that doesnt work at all. Just puts out a 2D image and limits the refreshrate even further.

This thread raised my interest, as supposedly a VT50 can be used at 1080p@120Hz, but aside this statement with the source pointing to itself (Laughing) I cannot find anything about it.
http://www.avsforum.com/forum/166-lcd-flat-panel-displays/1438092-list-hdtv-s-120hz-native-refresh-ability-forcing-1080p-120hz-via-dvi-hdmi-computer.html#post_22576928
The guys in this thread force 120Hz via custom resolutions, though. Maybe one would just need to find the right timing or something, if this television even supports 3D 1080p@60Hz at all.

So, unless one of you has a clever idea, im going to assume that this doesnt work.

Btw I do not want to use it as a 3D Display! I just want 120Hz for 2D.

Im not sure what to do with the EDID Confused

Put that in http://www.edidreader.com/, but im still not sure what to do with it. Also I maybe I may have overridden the original EDID with Custom Resolution Utility (CRU).

And there is another problem. AFAIK an EDID doesnt necessarily state the actual limit of the display capabilities, hence why so many people override their EDID to force unsupported modes.

As @Newty182 said, one big issue would be the bandwidth limitations for HDMI. Even if your TV supports the HDMI 1.4b spec (that has the 1080p120 support), I don't think that GTX 580 does.

I dont know if the TV actually supports 1080p120 and I was pretty surprised, that some of the professional panasonic displays actually seem to support it.

If the GTX 580 wasn't capable of it, would I be able to set it to 1080p120 as a custom resolution resulting in a black screen? Because thats what happens. Also sound over HDMI keeps working even at that point. Is that expected behaviour?

it could be, i had a dodgy cable between my projector and htpc that would do that at 120hz but worked fine at 50 / 60hz

Interesting.

So in the end, I currently know nothing? I dont know if my TV or my GPU is capable? Laughing

well if it lets you set it to 120hz (without faking it) it suggests tge eeid is saying it supports it.

i know on my box i can use xrandr to see all possible settings, no idea how to do it in windows.


Code:

<screen id="0" minimum_w="8" minimum_h="8" current_w="1920" current_h="1080" maximum_w="16384" maximum_h="16384">

xrandr output



try a lower resolution maybe, some only support 120hz @ 720p

Didnt work either. Though that would make the whole thing pointless anyway. I already sit "too close" for 1080p. I doubt the temporal resolution would make up for it Razz

I have to consider that this is a plasma though. These things may be be rather inflexible (with their PWM).
