I am planning to buy a CRT (low price, high refresh rate, no ghosting, no input lag). On some specs page they list different values for **maximum refresh rates** and **preset signal timing**.

For example on the specs page of Sony E430 I can read:

## Preset signal timing

```
VGA 640 x 480/60 Hz
EVGA 640 x 480/75 Hz
VESA 640 x 480/85 Hz
VGA-Text 720 x 400/70 Hz
VESA 720 x 400/85 Hz
SVGA 800 x 600/60 Hz
ESVGA 800 x 600/75 Hz
VESA 800 x 600/85 Hz
Mac 16" 832 x 624/75 Hz
VESA 1024 x 768/60 Hz
VESA 1024 x 768/70 Hz
EUVGA 1024 x 768/75 Hz
Mac 19" 1024 x 768/75 Hz
VESA 1024 x 768/85 Hz
VESA 1152 x 864/75 Hz
VESA 1152 x 864/85 Hz
Mac 2 1152 x 870/75 Hz
VESA 1280 x 960/60 Hz
VESA 1280 x 960/85 Hz
VESA 1280 x 1024/60 Hz
VESA 1280 x 1024/75 Hz
VESA 1280 x 1024/85 Hz
VESA 1600 x 1200/60 Hz
VESA 1600 x 1200/65 Hz
VESA 1600 x 1200/70 Hz
VESA 1600 x 1200/75 Hz
```

## Maximum refresh rates:

```
800 x 600/155 Hz
1024 x 768/121 Hz
1280 x 1024/91 Hz
1600 x 1200/78 Hz
```

Is this "maximal refresh rate" a theoretical maximal limit which I cannot set? Or is it possible to get 120Hz at 1024x768?

very important: it is fast paced high fps gaming (think quake, unreal, etc). Also, people will say, you can't differentiate 60Hz from 120Hz. I say its rubbish. We did informal blind tests and I could tell every time the difference. The 120hz feels really smooth compared to 60 or 75hz. – gnidoc Sep 10 '11 at 9:05
