10,000Hz LED monitor!

I can't believe this hasn't gotten more attention:

Thoughts?

Wow, that's amazing but the lack of information kinda annoys me. Like is it a 1bit video stream and thats why they could get it too 1000hz? Is this a standard OLED monitor they hacked? i will never know.

In the description he did give his e-mail address. Hopefully he's willing to share more information?

Cool, so let us know when he replies to your email

I'm very interested but I don't need ultra refresh rate but yes 10 kHz = 0.1 ms of persistence is very good for reduce motion blur.

That's if you can maintain 10000fps .

A lot of games based on the old Quake engine have strange effects when hitting certain fps. Quake had a problem were any fps over 72 would make you get stuck on any slightly angled surface and generally was a problem playing. In cod4 people would switch between different fps 125 - 250 - 300 to achieve different jump heights and distances. CS 1.6 and Quake Live have max caps that don't let you go over 100 and 250 respectively. And lastly CS:GO doesn't have a max cap, but anything over 1000fps will make everything speed up (I'm guessing it's if your fps is 1,200 it runs at 1.2x speed)

Not many games would even let us play over certain limits, i don't think we need to maintain 10000fps because i'm pretty sure the game wouldn't work

I got a response from the creator!

"Hi, I have make a simple explanation of the fast LED screen. Please have a look, you can ask me if you have any questions.
All the device is designed by myself.

He then attached a PDF, which I've uploaded pictures of. (The entire PDF was too large to upload)

It's as I suspected. He used many LED matrices to achieve the affect. 256 x 64 total resolution. That means he could have pixel-per-frame motion even if the objects are moving fully across the screen horizontally in about 25mS (at 10,000Hz. 250mS at 1,000Hz). At 144Hz, you'd only have that capability up to around 1.8 seconds.

That's impressive, but I'd love to get a "feel" for what 1000+ (Honestly, even just 144+) FPS is like, and I'm not sure if that resolution is enough to offer that (You'd get clear motion, but it'd be moving too quickly and for too short of a period of time to appreciate). It makes me wonder about those large LED signs you see, if they can be hacked. I also wonder if fast-moving objects will appear bright enough given that they're only in one spot for about 0.1-1mS at a time.

I also just considered the fact that you couldn't use PWM to control brightness for each individual frame. PWM at 10,000Hz and a frame rate of 1,000Hz would give you about 10 shades though.

I found someone who has made a 64 by 64 RGB LED display capable of 480Hz (or 160Hz with 2-bit PWM).

I'll continue doing more research.
