P2714T touch input lag

Marin Thomsen,

The P2714T User's Guide Touch specifications state that the Touch response time is <10ms. I do not know of any way to "speed" this up.

Hello Dell-Chris !

First , thanks for the fast response .You are right with the 10ms notice in the user-manual , that was one of the features of this monitor , which brought me to the decision to buy it . But in a life music situation you can feal the latency of your gear and i know from the latency of different soundcards , how 10ms feels .Hitting one of my virtual drumpads , for example , with a mouse click feels like no delay . When i do it with a finger on the P2714T , it takes a "long" time before the drum really sounds out of my boxes .(i would say a few hundred milliseconds ) .The specifications in the manual is for windows8 , could this be the cause ? I would upgrade , if you tell me , that it will be really 10ms then , although i then have to fight with the missing firewire legacy driver for my soundcard ...So if you google a little bit that problem , you will see i am not the only one with this problem , for example painting and drawing in photoshop , in principle all realtime computer actions , have to handle with this delay .

Hope you can help ...       Martin Thomsen

Correct, Touch is only Windows 8/8.1 certified. Dell cannot do anything about a non-certified OS.

So , to be sure before i take me in this trouble  ...: "The specifications in the manual is for windows8 , could this be the cause ? I would upgrade , if you tell me , that it will be really 10ms.... "

Can you affirme me , that after upgrading to win8.1 this lag ( i described above ) is only 10 ms ?

I can only rely on the specifications posted in the User's Guide. Another user of this monitor would have to post their experiences.

Hello Chris M !

Here i am back again , poorer and older but with a more or less working windows 8.1 pro 64bit. Unfortunatly my problem isn`t gone .easiest way to reproduce it is trying to paint in photoshop : the faster you try to paint the colour appears more behind your fingertip . Surely more than 10ms delayed response.In my Digital Audio Workstation it is the same plus another problem : If i hit one of my virtual drumpads with my finger , there is no sound , only when i lift my finger from the screen again . With my mouse the sound appears when i push the left click and not when i lift my finger from the button .

So , hope you can help now ....

Have a nice time        Martin

Interesting. All of our touch monitors do have a slight delay but well within our manufacturer specifications. The touch is never going to be instantaneous. What specific drumpad application are you using? Is it something we can download for free and test in our lab?

I use Battery 4 from Native Instruments , you can download a demo version from

http://www.native-instruments.com/en/products/komplete/drums/battery-4/downloads/

The same in my sequencer software , cubase 7.5 . For each Track there you have a piano roll ,it is the same phenomenon there .It is like a changed polarity : with mouse a click is the trigger , with touch the lifting of the finger.

The other problem with the timing is a little bit better since i switched to win 8.1 , but still the sluggishness of the reaction is not good , for using it as an controller i need direct reaction . But , maybe this is a window thing or build in this cool-touch-system thing , you use in your monitors .

Will download the demo and walk it over to the lab sometime this week. By the way, did you post your issues on the NI Forums?

Would be my next step after maybe having some results from you . And also contacting the Steinberg support (cubase ) , many people there in the community are waiting for a good working multitouch in this virtual studio , would be the step to reunite tradiditional studio work ( with many faders and knobs ..) with modern computer soft- and hardware.

When you calibrated (Control Panel -Hardware & Sound -Tablet PC -Calibrate), did you "feel" the same input lag as you do when running that Battery 4 software?

No. I did the calibration thing again , and its really fast .The " point " reaction isnt the problem on the desktop or in other windows programs ( like photoshop ) but the sluggish behavior , if  i move my finger .The delay is as bigger as faster i move my finger . Normally not a big problem , it is not good for realtime painting or realtime editing my audio mixes , when i have to move faders and knobs absolut correctly and exact in time .

The other thing is a different problem , until now i only realized it in my audio programs : When i use the touch of my finger as an trigger for sounds and drums , the polarity is reversed , as described above .
