Windows 7: Refresh Rate Stuck to 60Hz

nekov4ego · 30 Oct 2010

I know, I am here AGAIN, but it's great to know that there's a place where the members actually help you.

I have Asus X51RL and the Refresh Rate is stuck to 60Hz. Is it possible to make to change it a bit? I have noticed that ATI Radeon Xpress 1100 drivers aren't being updated by AMD, so I am stuck with what was on the CD that came with the laptop itself; it could be the graphics card's fault, but it could be a driver issue, or something with the LCD -- it's recognised as a Generic PnP Display, because no drivers for the LCD came with the laptop, nor are there some in Asus' website.

I don't think increasing the refresh rate on an LCD display has any effect? It makes a big difference on a CRT but is inconsequential as far as LCD's go. LCD's don't refresh, the pixel is either on or off. The big thing is to set the resolution to the native resolution recommended for that display. My two LCD's show up as Generic PnP Monitor in device manager, but if I go to the Screen resolution window they are listed as AG191. I have the option for 60Hz or 75Hz but I don't think it matters which one I use. I've always just left it at the default 60Hz.

Mine is recognised as Mobile PC Display in Screen Resolution. I have noticed that 60Hz aren't that bad on the laptop as they are awful on my old CRT, but I also thought it would still be better to have a higher refresh rate on the LCD. I read somewhere that some laptops didn't allow you to choose between 60Hz and 75Hz for example; perhaps I have one of those. The resolution is the highest possible (1280x800 -- the recommended), and it is OK.

So, I don't need to change the refresh rate? I haven't seen the difference on LCD displays...

I'm not sure about laptops, but most LCD monitors have a refresh rate 60Hz. In short, this is normal. CRT (tube monitors) have higher refresh rate due to their design.

Quote:

On smaller CRT monitors (up to about 15"), few people notice any discomfort below 60–72 Hz. On larger CRT monitors (17" or larger), most people experience mild discomfort unless the refresh is set to 72 Hz or higher. A rate of 100 Hz is comfortable at almost any size. However, this does not apply to LCD monitors. The closest equivalent to a refresh rate on an LCD monitor is its frame rate, which is often locked at 60 fps. But this is rarely a problem, because the only part of an LCD monitor that could produce CRT-like flicker—its backlight—typically operates at around 200 Hz.

So 60Hz are OK. Thank you very much for the help!
