I Fail: T91MT Has Pressure Sensitivity Too
Looks like there is pressure sensitivity, and unlike palm rejection, it appears to be global (but has to be manually enabled in applications that support it). Pressure sensitivity isn’t very noticeable with fine point brushes and pens, but you’ll see it if you switch to a marker or thick brush.
The ‘pressure sensitivity’ seems to be built into the screen (rather than into the pen tip like you may be used to), so my theory is that this resistive screen can detect point-width (rather than actual pressure), but what do I know?
One thing I did discover is that, at least in Journal, pressure sensitivity and palm rejection aren’t always compatible with each other. With palm rejection (IntelliWriting) on, I am sometimes unable to write with my palm resting on the screen while I am using a pressure sensitive enabled pen. Sometimes it works, sometimes it doesn’t.
Also, on my unit, ‘pressure sensitivity’ is very sensitive. I haven’t found a setting to change the sensitivity levels yet on a global scale. But if it isn’t apparent by now, I’m still learning. So if you have any tips, make a comment!
Kubel, just one quick question. How’s the weight on the stylus? Does it feel like a heave pen or is it light like a feather? Have you done any heave writing with it yet, like half a Journal page? I want to know how’s the feeling of writing with it.
Thanks.
The situation is much worst for me. With intelliwriting the text sometimes doesnt write regardless of whether the pressure sensitive was enabled. Add to that, the text is sometimes morphed going towards the bottom when it shouldn’t, while intelliwriting is turned on. This is far too frustrating for real productive work. Better off only using it for short annotations, turning off their palm rejections… Should’ve just brought the HP TX2…
Writing is most comfortable when you lean on the the edge – physical palm rejection… maybe Asus needs a software that let us scroll more easily while writing notes, so we only ever write on the edge of the screen, but then again any software asus comes up with is usually not a good deal…
Is funny how the touch gate looks different to the demo and on the front of the box compare to the real thing. Even with windows basic, 2gb of ram, super performance mode, the touch gate is way more laggy then the demo and the background has a less attractive design, on top of the fact that it offers no useful function in windows 7.
The stylus is mostly metal, but it’s not very heavy. It’s not pleasant to use since it can collapse while writing- depending on how you hold it. I still have a nice stylus / ink pen that came with my 701 touchscreen kit, so I think I’ll be using that as long as I have it.

You might be able to fix this by running the Windows 7 calibration utility, instead of the ASUS utility.
I am actually getting my T91mt today. With the addition of W7, larger SSD and the MT I felt it was worth trading up from the T91. One of the first things I am going to install is a trial version of sketchbook pro. I have it on my iphone and on a mac at work via a wacom tablet. Iam hopefull that it will bring a fairly natural sketching feeling to the screen. If your unfamilial with sketchbook check the page at amazon.

@Kubel
I am not talking about calibration, I am talking about the text while writing normally will get dragged downwards towards the palm occassionally due to the feedback from detecting your palm, morphing the text. If it was something as simple as callibration, I wouldn’t even think about it.
I’ve tested intelliwriting for a long while, no matter what I do, I cannot write fluidly for more then a couple of lines. It will often detect your palm as the pen, or sometimes it cause so much confusion it just wont write altogether, this is very frustrating. If I turn off intelliwriting, I was able to write fluidly as long as my palm is off the screen, but this is too tiring to do anything productive. I don’t know how much you’ve tried writing with intelliwriting but I’ve tested it for a long while, trying all different options and no matter what I tried, it runs into problems. It has lead me to believe software palm rejection is a bad idea, either that or Asus are bad are implementing software. It is probably abit of both.
On the subject of calibration, do anyone else have problem with the furthest top left corner of the screen, I can never get that correctly, a half a centermeter square at the top left corner in default landscape mode.
@Lucas
Interesting. For me its the bottom right hand corner.
@Lucas
I had a problem in the lower right corner- it simply would not accept my touch there while calibrating. The solution is to right click, go back to the previous point, and continue (repeating this as needed until it does calibrate).
Ok, I just noticed another odd feature. The system restricts clock multiplier to x6 (yielding 800-834 mhz depending on the power mode) if you use netbook in tablet mode. It only provides full speed in laptop mode. I am guessing this may be related to cooling. But still I would much prefer the processing power even in tablet mode. 1.33Ghz is already little enough 800 makes you tube sad.
Lol, sticking the Eee PC User manual deep enough in between the back of the tablet and the keyboard works to keep the clock multiplier at 10x. But I wonder if this will cause problems.
Hmmm, you guys are starting to freak me out with this product… I guess I’ll have to start hacking once I get it to get around all the limitations.
Would be great if someone can work out how to override that restriction (Tablet clock speed) with software. It’s the difference between youtube being watchable or not in tablet. I tend to spend alot of time in tablet with this netbook. You can tell then difference if you just run a youtube video in HD in notebook format then tablet, with CPU-Z. While the system it’s doing nothing it will lower the clock speed to 800/830mhz in both format and increase to 1389mhz when needed, but in tablet even with full load, it won’t go any higher than 800/830mhz.
That is a big difference, around 600mhz lower in power, almost approaching half the maximum clock speed.
I also notice I could play some MAME emulator games with this netbook, after a few tweaks it works in full speed on most games. It’s kind of funny seeing street fighter alpha 3 on such small system.
You can override the CPU speed by getting into standby while in PC mode then switch to tablet mode and start your PC again… You’ll have full clock speed
Thanks, it works! Not sure why they put the limit in, surely no one wants to use their tablet at 800mhz but at least we can get around it.
This blog has turned out to be a very valuable source of info. Thanks to all of you. For now I’m keeping my order hehe.
Now I remember what I wanted to ask: any cance of overclocking? Maybe not in tablet mode, but would be nice to be able to suck 1,6Ghz outbid it in netbook. Anybody willing to try?
The super performance mode in Eee Super Hybrid Engine is already a overclock from 1331 to 1389. I can tell you that already gets very hot for normal use. So I doubt a higher overclock would be useful. It runs too hot unless you use external cooling and if you use external cooling you lose the mobility.
Like all the other 8.9″ Eee PC’s, the T91MTs main heatsink is the plate beneath the keyboard. With a passive cooling system, it relies entirely on whatever air that is passing over the keys to keep the system cool. So underclocking and undervolting while in tablet mode is to keep the unit from overheating. I would like to do more tests, but I’m 99% positive it’s thanks to a simple magnet sensor. In all other Eee’s the removal of this small magnet is very simple. It will prevent the Eee from detecting tablet mode, but its removal will probably also prevent the system from knowing when the lid is closed (so you will miss out on many power-related features like auto-sleep and screen dimming when the lid is shut).
@TuxMeister
I’ve been spending the past few days trying. It seems the T91MT uses a different clock generator than the one found in the T91SA (which overclocks quite happily). A few clock generators I have tried seem to work (or at least show correct clock speeds), but all my testing has resulted in lock-ups. I haven’t gone through all the clock generators yet (there are probably hundreds), so help would be greatly appreciated.
The other option is physically disassembling the unit and searching the motherboard for the clock generator number. Work has really started to pick up lately, so I regret I haven’t had much time to play with my T91MT. But maybe around Tuesday (if no one else beats me to the punch), I’ll take mine apart and find out for sure.
I was really hoping for a BIOS like the one found in the Eee PC 1101HA, where you can manually set (in bios) how much you want SHE to overclock (by percentage). I’m really hoping for a bios hack that incorporates this feature in to the T91MT bios. I don’t have the know-how to do that myself.
I’m just received my T91MT and am working through issues successfully. I changed the 1gb memory for a 2 gb ram from amazon (crucial 200pinddr2sodimm 256mx64pc-5300) which was what amazon said to get and what another website said. Crucial only had information for the t91 and the ram was different (). I put the 2gb in and the computer appears to only be using 1gb of it according the settings page. What memory have you used? help…I can’t find info anywhere since the t91mt is so new.
Disable fast boot in BIOS and you’ll have 2Gb of RAM available. You can re-enable Fast boot after the first boot of windows with 2Gb.
i got some wierd problem, suddently my touch doesn’t work, I cant even touch it or drag anything, it odd all was okey some minutes ago (by the time hours..) Its irritating I bought this t91mt touch 2 days ago… and now its failing.. hmm any ideas what it is wrong?
