display that draws from the bottom to the top(!!)

I just finished testing a TV and discovered that it actually starts drawing the frame from the bottom of the screen, and finishes drawing about 15ms latter at the top. This seems super crazy - why in the world would you do that, since video signals are always sent in the reverse order (top to bottom...

Re: Does triple buffering add input lag?

In general, yes it's going to add lag.

Re: Input lag impact of dark stabilizer/black equalization monitor setting?

Do you mean dynamic contrast? I've never heard of black equalization. I've tested a bunch of older monitors and never see any significant change in lag with dynamic contrast, but I always turn it off because I think it looks ugly.

Re: Human Benchmark implemented in C++ DirectX9

Edit: seems there's a 5 frame penalty when VSync is enabled except when max frame rate is enabled too and less than VSync. So 60Hz 83ms penalty, 120Hz 42ms, 240Hz 21ms! At least that's how it seems to work on my system. Although I have no DirectX experience, I have to wonder if that's an artifact o...

Re: Human Benchmark implemented in C++ DirectX9

A transistor and a couple of wires to the mouse switch PCB connections, triggered by PC I/O. Strange thing if VSync is set on with 60Hz monitor https://i.imgur.com/5maM2HA.png From just to a few milliseconds with VSync off to a whopping ~78ms (mouse click latency removed). Almost 5 frames! That's s...

Re: slowest input lag you've ever seen?

Interesting, I hadn't really thought of chaining multiple devices together but of course that will take the crown for highest input lag for sure. But, I'm much more interested in how much lag a single piece of equipment adds, since other than as a lark nobody's combining the slowest video processors...

slowest input lag you've ever seen?

Question: what's the slowest input lag you've ever seen for a display? I just tested a "240hz" display (an old LG 3D TV). I was shocked. I expected something fast, even after discounting marketing hyperbole. Instead it was the slowest I've ever seen; 136ms in game mode and a whopping 177ms out of ga...

Re: Human Benchmark implemented in C++ DirectX9

The high intensity reaction time is what I was going for and what I am curious about. If the time window was larger, say 5, 15, 60 seconds, who's to say there are no peaks and valleys of your attention span and you just so happened to luck out and be extra focused on the narrow window when the scre...

Re: Human Benchmark implemented in C++ DirectX9

This might mean two different human-benchmarking standards, but both 1-second and 15-second randomization have merit even if some people disagree; There is merit in both the honest pre-primed benchmark and the honest non-pre-primed benchmark. I'm sure the 15-second delay would have shocking long de...
