Hack to use that 120hz LCD TV (including Plasmas) with your PC.

Kinda found this while searching for something else but cool none the less: http://hardforum.com/showthread.php?t=1766384

and: http://www.blurbusters.com/faq/120hz-pc-to-tv/

Will have to test this myself.... It's said that the 4K standard in HDMI uses the same bandwidth as 1080P 120hz....

I wonder if this works with RedMere HDMI cables? (Update: Checked and RedMere said there cables will work on 120hz Monitors. So should be good to go.)

Anyone else gonna give this a whirl and post results?

Whoever said that is wrong, 4k uses 4x as much bandwidth as 1080p at the same speed, so if you double the number of frames 4k would use twice as much bandwidth as 1080p@120hz.

Hmm, interesting.

Nvidia's new GSync seems interesting just because it might help push for displays to have inputs that let a GPU manage the refresh and any other processing. I'd love if this became ubiquitous as its definitely beneficial. Even consoles should be able to do this and it would be beneficial for them. Although I don't know what it'd take to get HDMI to support it which means it won't take off on TVs/consoles unless they add Display Port.

I think 4K is currently capped to 30fps on HDMI, so 1080p at 120fps would be the same bandwidth.

just use a res with the same aspect ratio as your monitor with toastyx's tool. there may or may not be frame skipping with my monitor (but if there is i dont notice it) as the ~3ms lag decrease going from 60 hz to 75 hz is well worth the drop in number of pixels (from 1920x1080 to 1600x900).

Here is a frame skipping test: http://www.testufo.com/#test=frameskipping (Recommends to run in Chrome.)

Don't 120hz Monitors use dual-link DVI only for 120hz and not HDMI? Even though HDMI 1.4(some 1.3) can handle this? So are 120hz Monitors starting to offer HDMI 1.4 support?

Anyone try this yet?

If they made TVs natively support 120hz for consoles and such they would tack on a few extra hundred or most likely thousand bucks for the TV. Same with 120hz Monitors.

HDMI 1.4 can support 120hz. Why is Display Port usually used instead?

I would think the issues caused from resolution scaling would nullify that, at least for me it personally would, unless you went with a resolution that scaled evenly but then you'd end up with a really low res upscaled or a really high res monitor. I'd be interested to see how upscaled 1080p looks on a 4K monitor of a typical 1080p size display.

I'm not talking about 120Hz, I'm talking about the ability for the GPU to handle the monitor's updating (which means the GPU only tells the monitor to update when there's a new frame for it to display). Go read up on GSync. Right now HDMI does not support what would be needed to let the GPU manage that, only Displayport does (and even it would need to be updated or have a special processing board which is the route nVidia is taking).

im fine with fewer dpi since it is the same aspect ratio which means no artifacts. gpu scaling works perfectly for games that i need to use a 4:3 resolution for.
