Congrats on the purchase, just FYI I run 2 x 660ti in SLI overclocked and they can just about handle this res for stuff like dota 2, BF 3, CS:GO all maxed out settings, while hitting over 96fps to make the most of my monitor overclock.

Sorry for the ****ty picture, light is really shoddy this time of the day. But just finished mounting my two Crossovers to my 2x monitor stand.
To the left the 2795 QHD (with ugly foot sticking out, going to remove that one later) and to the right its big brother 27Q. biggrin.gif

for example 60 hz = 5 ms input lag
90 hz = 4 ms input lag
100hz = 3 ms input lag etc?
does different Refresh rate = faster input lag or input lag will be the same as out of box and overclocked.

I don't think any of us have the proper equipment to test input lag. I doubt anyone here could properly answer your question.

Crossover 2795QHD AHIPS LED error-free input of the rack is measured in 2.64ms in general use and gaming
is that overclocked or out of the box 60 hz ?
but 2.64ms input lag is seriously awesome. smile.gif
by the way hows your monitor when it arrived any defects ? the past few posts have been defects mostly. still waiting and praying for mine.

Probably out of the box 2.6ms. Mine arrived with no defects. But currently I'm having an issue where it powers off for a second or two and powers on again. I suspect the power supply but could possibly be pulling too much from the wall? I'll look into it. It doens't happen often but enough to be annoying.

I can't find anything conclusive on how refresh rate affects response time. What I did read is that say you overclock 60 to 120 and it takes 10ms to go from one frame A to B, you now have Frame A > 5ms Frame C > 5ms Frame B. Same 10ms but with a frame in between. Response time would be that it takes Pixel D in frrame A ?? ms to go from White to Black to White (or grey to grey). I'm no professional but that'd have no effect from the refresh rate except that frame C would have pixels that are already at a certain color/value before frame B happens. Again... not a professional here biggrin.gif

this one stuck pixel is triggering my OCD so hard.... Will it go away with time? (tried heat, pressure, tapping, flashing, etc...)

There doesn't seem to be any rhyme or reason with stuck pixels. I have seen some go away years later, some right after rubbing them out and some never. I did the same as you and I tried my best to ignore it but I could never un-see it so I was able to get a replacement. Hopefully, the next one will have zero.

I think you might be misunderstanding the nature of input lag.

Input lag in overly simplistic terms is the delay related to how long between the monitor receiving a video signal from the computer and actually processing/displaying it.

Refresh rate wouldn't affect input lag any more than the space of time between two frames. If you are asking if a higher refresh rate would affect the single digit ms because the frames are compressed, the answer is yes it would be a few single ms faster simple because more frames are being delivered per second.

The real question is whether there is any meaningful ADDITIONAL delay caused by extra processing in the monitor's control board.

In the case of the Crossover, almost certainly not. It should be virtually the ideal case because it is nothing but a single input DVI controller, without even so much as an on-screen display.


My point here, is that your question isn't really a necessary one. The screen by it's nature will have supremely low input lag because it doesn't have any unnecessary processing going on internally, and it also happens to overclock to a nice refresh rate which by the nature of running a higher refresh rate and compressing frame times lowers input lag a tiny hair more.


As a contrast to the very fast Crossover, or my previous very fast BenQ 2720Z, I have a nice 47" 1080p TV that I used for several years for gaming, but discovered the up to 75ms display lag really doesn't cut it for any kind of competitive gameplay. So yes it matters, but this screen will be among the best you can possibly get for input lag.

I assume you paid for the pixel perfect version? I didn’t :/

Question on this monitor.

Flying up to the states this christmas, and would like if possible to bring it back with me to Colombia, as shipping + taxes would equal half of the monitor's costs.

Question is, with what or how would I be able to test it out to ensure the monitor received at least works and turns on ?
