1080p @ 120hz

[sevenmonkeys]

Hello everyone. I have a display that can support 1920 by 1080 at 120hz. Is their a way to make the Mister output 1080p 120hz. I can get 4ms latency at that resolution. Thanks.

Nope.

You aren't going to get an effective 4 ms anyway because none of the Mister systems actually run at 120hz. Plus you'd have to engage vsync_adjust=0 which is going to add a buffer I.E. latency. Your best bet for latency, if your display can sync to it appropriately, is always going to be vsync_adjust=2, to get frames out as quickly as possible that match the core's original refresh rate.

Anything over 1920x1080p@60hz is considered overclocking the pixel clock on the DE-10.
And 1920x1080p@120hz is double the pixel clock so there is no chance at all.

It might be possible to do it at much lower resolutions, like 720p or 480p with custom video modes, but it still might be hard-locked by the hdmi chip, and as said above won't change the situation.

I really want to get 480p at 120hz or 100hz for pal to avoid flickering on my viewsonic crt

That's a bad CRT if it flickers.

i wanna say 240p @ 120hz is possible right now. but like others have said, 1080p @ 120hz is way past what the de-10 nano can do.

i am looking forward to the next generation (or possibly nextnext generation) FPGA hardware to allow for a doubling of the original refresh rate with a built in BFI or some other trickery to blank out the doubled frames and achieve better input latency compared to 60hz and improved motion clarity over HDMI.

but, there isn’t anything wrong with what we have now. I can play input sensitive retro games on my LED computer monitor without issue. 120hz would just be a nice-to-have feature. its not a dealbreaker by any stretch
