I have an asus V6J and I aboslutely love it mainly because it allows me to set the refresh rate of the screen to 100hz. It is amazingly smooth in games, but lately my laptop has been going through a lot of problems, irregular battery wear, microphone static due to EMF with ethernet port, stopped charging due to powerful soldering iron that was plugged in on the same power strip.. still i don't want to abandon this laptop because of the screen.
However, i am frustrated trying to figure out if there are any other laptops in the entire WORLD that can do what my laptop and the other laptops based off the v6 series can do:
Set the refresh rate of the lcd screen
Now before anyone posts anything about:
- your eyes can't see more than 60 FPS
- no such thing as refresh rate on a lcd
- only response time matters
- LCD's only run at 60fps
i've gone over this extensively over at this forum and thread:
http://www.xbitlabs.com/forum/viewtopic.php?t=13269&postdays=0&postorder=asc&start=0
So please read that before any criticism please! i'm asking for a favor
Anywho
I want to ask of everybody to check on their laptops if they can run above 60 hz. How?
IF you are not comfortable changing settings and are afraid of breaking something don't do it! Proceed with your own risk. This little trick shouldn't break anything IN MY OPINION
I used a utility called powerstrip( http://www.entechtaiwan.com/util/ps.shtm) to do this
install powerstrip
restart your computer(when it asks)
start up powerstrip(if it doesn't already startup)
in your system tray you will see a monitor with a diagonal rainbow strip comming out of it This is the icon for powerstrip
right click on that
go to display profiles
click on configure
Okay from here see if you can click on "Advanced timing options" if you can you probably can't do this trick and your laptop probably doesn't support changing the refresh rate
but if you can a dialog should pop up
under "Vertical Geometry"
Do this very carefully
Note: Before doing this Know that PRESSING ESC will Cancel any changes and revert back to normal (pressing esc will close the dialog DON"T CLICK OUT OF THIS WINDOW(you might be able to alt tab to it blindly):
highlight everything in the Refresh Rate box
type in 75
Press TAB
If this works 75 hz probably works on your lcd
try going higher say 80
90 etc..
100
you should notice quite a bit of a difference here if you move your windows around they should be very smooth compared to before
if you play any games that are capable of going up to 100 fps they should be much more smooth too
EDIT:
I have gotten a new laptop posted here:

There is, it just denotes a different thing
Response time has to do with tearing. Less response time, much less tearing.
That is if the LCD has a 60Hz refresh rate. If it's a 75hz or 100hz LCD, it can display 75 or 100FPS
To the OP. There very likely isn't. The V6J was among the last to have an IPS screen, which is superior to the TN screen nearly all laptops use. The higher quality screen allowed you to do just that. -
LCDs don't handle refresh rates like CRTs. infact you can say LCDs don't have refresh rates if you comparing them to CRTs.
-
"Anything over 60 fps is adequate, 72 fps is maximal (anything over that would be overkill). Framerates cannot drop though from that 72 fps, or we will start to see a degradation in the smoothness"
Read here -
Well... I looked into it a bit more indepth. Like I said, the refreshrate displayed in, say, display settings in windows, just denotes a different thing.
There is a correlation between a LCD's response time and a CRT's Refresh rate. They are inversely proportional, so using a math formula, you can compare them. I.e. 1/(10ms*1s/1000 ms)=100hz. Or just do 1000/(LCD ms rate)=Hz.
However, you still need a 100hz panel (10ms response time) to be able to display 100FPS.
The correlation between ms and hz
And of course, the eye can see more than 60fps. (read this, this and this article
So that's what you should look for, a laptop with a pixelresponse time of 10ms or faster. -
To quote my (2002) article
It used to be, well, anything over 30 FPS is too much. (Is that why you're here, by chance?)Then, for a while it was, anything over 60 is sufficient. After even more new video cards, it became 72 FPS. Now, new monitors, new display types like organic LEDS, and FPDs offer to raise the bar even higher. Current LCD monitors response rates are nearing the microsecond barrier, much better than millisecond, and equating to even more FPS.

But the response time doesn't matter no matter how fast it is unless the laptop or video controller of the laptop or the lcd controller of the laptop ALLOWS you to change the refresh rate!
Hence this is why i am asking for people to check to see if they can change their refresh rate on their laptops
just to note: actually the v6j never had IPS screens but only the v6va's did but those screens will work in a v6j -
Oh, sorry about that. I thought all V6's had IPS screen options.
Hmm, many LCD's backlight refresh rate is 60hz, and that could a part of why it can't be changed. -
As for modern lcd backlights manufacturers developed a way for them to be operating at well over 100hz. Nominal AC current is at 60 hz, because of that some light bulbs produce an annoying flicker like crts do. Same thing would happen with 60 hz lcd backlights.
Also the backlight operation is independent from the system to change the LCD part. You can infact unplug the LCD controller but still see a light. Its like an overhead projector. (You can infact create a slipshod computer projector by taking apart the a lcd and putting it on a overhead projector so it uses the bulb instead of a backlight) -
If it uses a 60Hz backlighting (modern LCD's Still use them), it might give you a headache. Actually, I don't know why I brought it up. I blame it on my belly ache and low amounts of sleep.

Sure the age of the article can have an impact. Human limitations can't be upgraded, but research methods and scientific evolution can be. But this is really getting off-topic.
To the OP, I am not aware of any laptops that can do 100 Hz. -
Right, but your not getting the basic concept. There is absolutely no flickering/refreshing involved on a LCD, so a single pixel is a continuous stream of color until the video card/adapter tells the pixel to change color or turn off. The response time applied only the how fast each pixel can flicker/change to form your animation/image. The backlight of an LCD panel doesn't flicker either(nor can you change this when you change the refresh rate), it stays on when the monitor is on. This has nothing to do with the refresh rate and the refresh rate won't be significantly noticeable between 60hz-100hz regardless on a LCD monitor simply because of the properties of how LCD panels work.
You should also look into the "ms" claims, not all monitors perform exactly what they claim ie; 4ms, they tend to be much slower on technical stance and can only be 4ms in certain situations(like grayscale etc). -
You're right about the response times claim. The number can either state Grey-to-grey or black-to-white. I was talking about grey-to-grey. -
It is true that the pixel on an lcd monitor will not change until it gets told. How often is this command sent? The refresh rate determines this. Most lcd's don't get changed more often than 60hz, 59 hz, or whatever is set. Now my laptop model series the Asus V6J may be the only laptop IN THE WORLD that can change the refresh rate. I once again cannot actually show anybody this because i don't have a video camera capable of recording 100 or more fps with which i can slow it down to see the difference in updates.
I am fully aware of the response time claims of lcd monitors. In fact i basically disregard them or i +-15 ms on it to get a very very rough estimate. I only trust one website on reviewing LCD monitors and that is Xbitlabs.com
They do the most technical reviews i've seen for LCD monitors testing REAL contrast ratios REAL brightness REAL response times
3d graphs etc..
take a look at this review and you'll see what i mean. I really recommend this website for lcd monitor reviews
http://xbitlabs.com/articles/other/display/20inch-5.html -
i was hopping that the thinkpad t61's supported this because i might want to get one of those. However powerstrip doesn't support changing refresh rates on the 8 series.
Can anyone check this?(by using powerstrip to try to change refresh rate with the method on the first post) -
anyone? i suppose since there really isn't a demand for 100hz lcd especially for laptops no one really cares :/

60hz is normal, a few lcd's work at 70 but 100 is insane. I wonder if you even geting 100hz. You can "force" a higher refresh rate on alot of LCD's but in reality the hardware is not giving you the higher setting and it can damage it too.
The only benefit you will get obviously is that if your laptop is producing more than 60fps in the game, that you will be able to see the extra frames produced on your screen. The game itself tho may not even have a difference between those frames so the extra 40 frames you want to see with a 100hz refresh many of them will probably be duplicates. Ontop of that I cant think of many laptops (if any) will get over 60fps at any reasonable setting on a newer game. -
Dudessss... my friends...the refresh rate of our eye is around 18 FPS..
All movies are made at 24 FPS...thats why u are used to 24 FPS minimum...and the Reason why u cant enjoy Crysis below 24 FPS. Just FYI
google for "persistence of vision" if u didnt pay attention in your high school -
Also, persistence of vision only describes why we see streaming animation instead of a series of pictures - because our brains are capable of tying one and one together to create fluid movement.
And oh, the google suggestion: From Wikipedia,
-
Yes, thank you very much! there is nothing limiting us to seeing just 24 fps only
Also there are a lot of interpretations of "see"
I could mean to: distinguish as individual pictures
or see how fluid it is
and of course whenever we are using "how" something is, we have to be comparing to something else. So How fluid the motion of 24 fps is compared to 60 fps. Likewise there is an increased fluidity compared to 100 fps. -
I'm kind of reviving this thread. It has been a while since this thread was made and since then I've gotten a new laptop: Thinkpad T61p 4:3 14.1". I am quite happy with this because the lcd screen can run much higher than the Asus' could--150 hz vs 100hz with limited color distortion(on darker colors there are VERY feint scattered yellow lines that are at least persistent)-- and it also had similar "underclocking" going all the way down to 15hz--saves a good amt of battery life.
Since the thinkpad's nvidia quadro 570m is based on the 8 series, powerstrip doesn't work for it. I actually had to use nvidia's super buggy control panel to try to add these settings. I had to contrive a convoluted procedure going back and forth through various parts of the cp to actually successfully add a new resolution and refresh rate.
I think I am picking up a correlation with which laptops can do this:
They must have a relatively new nVidia discrete graphics card(from the mobile 6 series perhaps..) However I am speculating from a very small sample size(from laptops that have: ati mobility rage pro, geforce 4 go, any intel based, ati 9700, ati 320m) Or I could have been just lucky.
Laptops that can do this:
Thinkpad t61p nvidia 570m (140m maybe works too)
Asus V6J
Laptops with nvidia graphics (newer ones, 6xxx,7xxx, 8xxx) need to confirm these though
Laptops that Probably can't:
Intel based graphics
Ati based graphics(after 9series maybe...)
nvidia(up to gf 6 series)
Any laptop out there that can do at least 100hz refresh rate (not including asus V6J)
