Q. i have new lcd monitor LG 2241A 22inch. i have alienware m11xr2. i connected the laptop to lcd monitor using HDMI cable. i installed the driver first. it worked, but only able to set the refresh rate to 25Hz at 1920x1080.
why can't i set it to 60Hz? do i need to install any?

A. Drop resolution to make the refresh rate higher. This shows the limit of the video chipset in the laptop:
"With a resolution of 1366x768..." http://www.notebookreview.com/default.asp?newsID=5766&review=alienware+m11x+r2+core+i7 shows the native resolution of the laptop screen. The video chipset was designed for that. When you connect to another screen at higher resolution, and keep the first screen active, the video system has to service both. The refresh rate is lower than what you wish.
"Speaking of automatic features, the M11x R2 also includes the same Nvidia GeForce GT 335M discrete graphics card with 1GB of dedicated GDDR3 memory as well as automatic switchable graphics thanks to the Intel GMA 4500MHD integrated graphics and Nvidia Optimus technology. For those who don't know what Optimus is, it's basically a technology that allows the computer to automatically use discrete graphics when you need them (like when you're playing a game) and switch to integrated graphics when you don't need extreme graphics performance and need maximum battery life." http://www.notebookreview.com/default.asp?newsID=5766&p=2
Perhaps yours is not switching to the second video system when you do the games?
"However, to all of your amazement (most likely) I might have found a solution. I updated the BIOS, and both GPU's drivers to the latest on Dell's site. Alienware is rather proprietary and they say they "optimize" driver updates to their system. I think thats a load of crap, hence the proprietary statement. But here's the point, the issue is with Optimus. Nvidia's optimus has issues with certain games on when it should turn their GPU on, even if you have a profile set. So I set profiles for all the .exe files in the RIFT game folder and unchecked "Show games only on my system" in the profile manager." http://forums.riftgame.com/rift-general-discussions/tech-support/146481-optimal-video-settings-alienware-m11x-r2.html

Monitor Refresh Rate?
Q. Ok, I used to have an old computer that had windows XP and a Generic non-PnP Monitor. In the settings, it showed I could only put the monitor's refresh rate up to 60Hz. I later bought a new computer with a much better CPU & GPU., but I am still using the same monitor. Now, It shows that I can put the refresh rate up to 170Hz! However, I still cannot check the "Hide modes that this monitor cannot display" option, though before 170 Hz never showed up on the list at all.
-Can I actually increase it up to 170hz (doubt it)?
-If not, how could I find out how much I can increase it to?

A. Computer monitors often have a "maximum refresh rate" listed in their technical specifications. Google the make and model. This number, measured in hertz (Hz), determines how many times the screen is redrawn each second. Typical refresh rates for CRT monitors include 60, 75, and 85 Hz. Some monitors support refresh rates of over 100 Hz.
The higher the refresh rate, the less image flicker you will notice on the screen. Typically a refresh rate of less than 60 Hz will produce noticeable flicker, meaning you can tell the screen is being redrawn instead of seeing a constant image. If the refresh rate is too slow, this flicker can be hard on your eyes and may cause them to tire quickly. As if sitting at a computer for several hours wasn't hard enough!
To avoid flicker, you should set your monitor to use the maximum refresh rate possible. This setting is found in the Monitors control panel in Windows and the Displays system preference in Mac OS X. While 60 Hz is considered a good refresh rate, some people will find that 85 Hz is significantly better.
The maximum refresh rate is determined by three factors: 1) The rate your video card supports, 2) the rate your monitor supports, and 3) the resolution your monitor is set at. Lower resolutions (i.e. 800x600) typically support higher refresh rates than higher resolutions (i.e. 1600x1200).
If you have an LCD monitor, you may not be able to adjust the refresh rate. This is because most LCD monitors come with a standard refresh rate that is well above the "flicker" point. LCD monitors produce less flicker than CRT monitors because the pixels on an LCD screen stay lit longer than CRT monitors before they noticeably fade.
