Re: ULMB(lighboost) & G-sync? [What are technical challenges

Is it possible to force ulmb + gsync? so that the strobe length is constant This would not cause visual problems if the game's framerate is exactly consistent. For example csgo can easily be capped to exactly 120fps No this is exactly the problem gsyncs functionality would be lost. Gsync fixes prob...

Re: ULMB(lighboost) & G-sync? [What are technical challenges

Ah I get it I think, the only pixels that will benefit from these larger blanking intervals are the bottom pixels. So at a speed of 144hz = 7ms scanout which is likely the limit for the benq I assume. The bottom pixels then have an advantage of 3ms if you compare it to 100hz = 10ms. The blanking int...

Re: GSYNC Input Lag Test Results in Chivalry: Medieval Warfa

Got a great idea for everyone to test input lag. Simply bind an action (like fire a gun) to the capslock, scroll lock or num lock in the game and record the light. :D Now you only need a good camera.

Re: ULMB(lighboost) & G-sync? [What are technical challenges

I think I might have formulated it a bit wrong by saying the response time will be improved. What I meant is that the pixel is activated earlier meaning it has more time to transition between colors right? But if this is the case what about ips displays that in general have slow response times. By u...

Re: ULMB(lighboost) & G-sync? [What are technical challenges

Great stuff I can really see you love this subject. And I also see how little I actually know about the technology. Especially the vblank stuff and it being not being long enough to allow these increasing strobe times. I had actually no clue about those colours I assumed an led would remain correctl...

Re: ULMB(lighboost) & G-sync?

Strobe length needs to be ultra precise, so software controlling exactly when the light comes on, and when the light comes off, is extremely hard. With 1 millisecond persistence, a 10 microsecond mistake in the strobe length causes a 1% brightness variances. (1/100th of 1 millisecond flash, equals ...

ULMB(lighboost) & G-sync? [What are technical challenges?]

I have been browsing the forums a bit. And I see that the combination of both lightboost and g-sync is not a possibility at the same time. But what I think is strange is that Mark says it would not be possible via software (http://forums.blurbusters.com/viewtopic.php?f=5&t=564). It seems rather weir...
