looking for LCD at 85Hz

[Xarbat]

I am looking for an LCD that displays a 1440x900 resolution at 85Hz.

I use VSync when I play video games so I want the 85Hz so I can get a constant 42.5fps.

Also, if it is below $150 that would be good.

No LCD has 85Hz. 75Hz is the max and is usaually down scaled to 60Hz by the monitor.

Refresh rate for CRTs and LCD are different. For LCDs, it refers to the frequency at which the video card transfers image data to the monitor.

Which still means I will be playing games at 37.5fps on a 75Hz LCD as opposed to 42.5fps on a 85Hz LCD.

the refresh rate for the ViewSonic VX1932wm is always listed as 85Hz, unfortunately that model has been discontinued; I want to know if there are others.

Why would you be playing at half speed? Vsync would only limit you to 75Hz, not half the frame rate.

In the games I would use video settings that would make the minimum fps somewhere between 43 and 55 fps. It would take the video card longer than 1/75th of a second to create a frame, so it would be 2/75ths of a second when the monitor receives the image.

no. no.

NO.

Vsynch caps your maximum FPS at the refresh rate. Vsynch and refresh rate of 60hz = 60fps max.

I don't know who told you that kind of garbage but if you don't believe me, go ahead and try it on your machine. Set your resolution and details to something lower than usual, enable vsynch and try different refresh rates. You'll see that it caps at 60, 75 or whatever max refresh rate you got.

I am right, you are looking at average framerate. With VSync on, using a 60Hz, monitor the FPS will be limited to 60, 30, 20, 15, ect. Triple Buffering will allow the video card to store a frame and work on a new frame while it is waiting for the next refresh, which basically means you might have one out of three or more frames take 1/60th while the others take 2/60ths.

Don't use 60Hz unless you like looking at 30fps.

I read it and I also read the date of that post:

In 2005, triple-buffering wasn't exactly crazy new tech. 3.5 years later, it is sort of widespread 😉

VSynch isn't quite an issue anymore.

Hi,

Is there a theoratical obstacle for not having 85 hz lcd? Thanks.
