Timmy94 Posted October 2, 2008 Posted October 2, 2008 Hey guys i just got a new lcd and it can go to 75hz. would this make a diff in perf to 60hz. Cheers Share this post Link to post Share on other sites More sharing options...
Sharp Posted October 2, 2008 Posted October 2, 2008 Yes, always run the screen at the maximum Hz. The higher the Hz the smoother the display will appear. Share this post Link to post Share on other sites More sharing options...
The Smith Posted October 2, 2008 Posted October 2, 2008 Hz are like the frames per second your monitor displays. So higher is better. Share this post Link to post Share on other sites More sharing options...
Waco Posted October 2, 2008 Posted October 2, 2008 I'd like you to find me someone that can see the difference between 60 and 75 Hz. Share this post Link to post Share on other sites More sharing options...
Error 404 Posted October 2, 2008 Posted October 2, 2008 (edited) Hz is cycles per second. KHz is one thousand cycles, MHz is one million cycles and so one. 60 Hz means that you monitor refreshes it's image 60 times per second, and 75Hz, while not a great CPU speed, refreshes your monitor at 75 times per second. ~Error Edited October 2, 2008 by Error 404 Share this post Link to post Share on other sites More sharing options...
The Smith Posted October 2, 2008 Posted October 2, 2008 I'd like you to find me someone that can see the difference between 60 and 75 Hz. Yeah the human eye and brain cannot see the difference, but in theory, it's better. Also it's a kind of a limit to your GFX card fps it displays. That is why there is an option in the display control panel called "Vertical synchronisation". It limits your GFX card fps to the monitor's refresh rate, because anything over it is kind of wasted.

hardnrg Posted October 2, 2008 Posted October 2, 2008 I'd like you to find me someone that can see the difference between 60 and 75 Hz. With LCDs, it's effectively a maximum frame-rate cap, and the eye can see into 100s of frames per second Share this post Link to post Share on other sites More sharing options...
fire_storm Posted October 2, 2008 Posted October 2, 2008 I thought that the response time of an LCD was more important then the number of HZ it can do at a certain resolution. Share this post Link to post Share on other sites More sharing options...
iKillSteal Posted October 2, 2008 Posted October 2, 2008 Response time was a huge selling point back in the day when 30ms was considered "ok" and ghosting was a common thing people just lived with. Now-a-days it's all a big load of marketing BS. You would have to be the bionic man in order to pick up any difference between a good 8ms, 5ms an 2ms(Sometimes companies "cheat" to get an advertised refresh rate of 2ms) panel, all other factors aside.

airman Posted October 2, 2008 Posted October 2, 2008 (edited) people that say the human eye can't tell the difference between 60hz and 75hz are only half correct. YES, looking at, for example, a red blinking LED - the human eye cannot tell the difference between even 30hz and 60hz (just looking straight at it with no motion). put that blinking led on a string, twirl it in a circle, and you can obviously see the difference. this adds to my next part: do an experiment for yourself. take a game like counterstrike, for example (or one that you are capable of having high framerates in) and set the max fps to 30. move your mouse around to look around, move, shoot your weapon, etc. note how "fluid" it seems. now, uncap your framerate. can you tell a difference on how fluid the motion is? it's quite obvious. staring at your monitor at 60hz and 75hz on your desktop will not make a lick of difference. in game - if your gfx is capable of 75+ fps, you'll see the difference for sure.

Fogel Posted October 2, 2008 Posted October 2, 2008 (edited) Short Answer: Yes! Long Answer: What you see is limited to your Monitor refresh rate. So if your system is capable of producing 100 FPS on Bioshock but your Monitor is refreshing @ 60Hz than you are only seeing 60 FPS. This is true whether not Vertical Sync is enabled or not - only difference is with it enabled all the xtra frames are dropped completely. With it not enabled your video card can render them as fast as it can, but you're still going to be limited to your Monitor's refresh rate. Far as what the human eye can see... well that one is still one big mystery as there are way too many variables that cloud the issue. Supposedly it is 60 FPS and the industry strives between 30 and 60, but the human eye interpets light and images in different ways. So the answer to the question is it limited to 60 FPS - is... yes, no and maybe so. Best writeup I've seen on this Great site for movie editors as well So it appears it depends on: - Refresh Rate on Monitor - How the movie/game was created - What's going on at the time as frame rate won't be constant ...especially when it comes to games - What part of the eye is taking in the information Monitor response times is a completely separate issue and there is no industry standard on what they have to report. Many times if you see 2ms they are referring to G2G. (not to be confused with Good To Go) For monitors this response time means Gray To Gray. This is the quickest possible change a pixel can make and is usually what Monitors advertise as it makes them look good. The other response time is Active Black to Inactive White back to Active Black which is the slowest response time. Few companies advertise this, unless their monitor has a good response time. I find ViewSonic to be best with this but your mileage may vary. I don't pretend to understand it all, but it is rather interesting to read about.
