The display has reasonable resolution for most uses.
the drivers suplied in the cd are useles for raspberry pi, but work fine for windows and UBUNTU distros on PC, on XBMC distros there is no easy way to calibrate.
Tried to build the image of kernel with no sucess.
A real help shoud be a SD card image of raspbian 13.12 for Pi B+
Please, can someone post a link for a SD card image file.
- Overall, I'm impressedReview by Sekwel
Quality Value Price
I purchased this screen so that I could mount it to the front of my MicroATX tower. I'm running windows 8.1 64 bit. The screen arrived promptly, and was adequately packaged. The board automatically set the screen to display at 1920x1080 right off the bat. And, oddly enough, it does not seem to have a 'native,' resolution. Either way, I was impressed with the display clarity even at that resolution -- not exactly readable, but not unusable by any means. That was an unexpected bonus that was perfect for my needs.
The display will automatically turn on once it receives power, and then shut off as a screen-saving measure. I was able to use a USB cable lying around that matched the power connector on the board. So, in short, USB voltage is sufficient. Setup was easy, although it took a bit of figuring out.
My one legitimate complaint is that it did not include the remote control listed in the description. Since I don't really need it, I haven't bothered to contact SainSmart about it. But, I'm sure they'd respond quickly if other reviews are an indication.
Just a note, for people who want to use it with windows 7/8/8.1 64 bit: The touch controller included isn't HID compatible. This means that, without the proper drivers (which I haven't been able to find after weeks of searching), the touch overlay will read as a mouse, rather than true touch input. Since the product isn't aimed at Windows 8 users, I'm not counting this against a good review -- I just figured it would be good information to have. It would be possible to purchase another 4-wire touch controller that was compatible, though.
- Great Device but get the latest driversReview by steven m sikora

I love this touchscreen, however the first model had a bad touch interface. Luckily SainSmart's customer service is great and after a little troubleshooting they confirmed my interface film was bad and sent me a new one.
I was able to get this touchscreen setup on both my windows 8.1 laptop and windows 7 pc, just needed to download the latest eGalax Touch drivers. With the latest drivers this thing rocks.
- Five StarsReview by Mario Mendes "Mario Mendes"

Great product. Works with my Pi B+ and the Beaglebone Black. This is what I did to get it running with the RPi (the BBB process is pretty much the same):
The drivers are already there for the RPi, at least it was for the B+ (which is the one I have).
I had to build the kernel to get the screen to work. I did that from an Ubuntu VM running 3.13.0-35-generic 32-bit (VMWare Player).
This is what I did:
Attach the controller to the RPi and check that it sees the screen, you're looking for an eGalax entry:
Bus 001 Device 005: ID 0eef:0001 D-WAV Scientific Co., Ltd eGalax TouchScreen
$ cd ~
$ mkdir src
$ cd src
Get the kernel sources:
$ wget https://github.com/raspberrypi/linux/archive/rpi-3.12.y.tar.gz
$ tar -zxvf rpi-3.12.y.tar.gz
$ cd linux-rpi-3.12.y
$ sudo apt-get install git libncurses5 libncurses5-dev qt4-dev-tools build-essential
$ sudo apt-get install gcc-arm-linux-gnueabihf
Make sure the source objects are clean:
$ make mrproper
Create a folder for the generated kernel:
$ mkdir ../kernel
Genereate the .config file:
$ make O=../kernel/ ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf- bcmrpi_cutdown_defconfig
Configure the kernel:
$ make O=../kernel/ ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf- menuconfig
Navigate to Device Drivers -> Input Device Support -> Touch Screens and select it. Go to USB Touchscreen Driver select it. Go to "eGalax, eTurboTouch CT-410/510/700 device support" and select it. Exit all the way and save the file when prompted.
Compile the kernel:
$ make O=../kernel/ ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf- -k -j3
The -j3 option enables parallel build. The number should be the number of cores (of the machine where you're compiling) +1.
The build took about 10 minutes on my pc. When the build completes, you will have the new kernel in ../kernel created above.
Create the kernel image:
$ cd ../
$ git clone git://github.com/raspberrypi/tools.git
$ cd ~/src/tools/mkimage
$ ./imagetool-uncompressed.py ../../kernel/arch/arm/boot/Image
Build the modules
$ cd ../../kernel
$ mkdir ../modules
$ make modules_install ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf- INSTALL_MOD_PATH=../modules/
To replace the kernel, get the latest firmware:
$ wget https://github.com/raspberrypi/firmware/archive/next.tar.gz
$ tar -zxvf next.tar.gz
In the small partition of the SD card (/boot):
- replace the /boot/bootcode.bin in the SD card with ~/src/kernel/firmware-next/boot/bootcode.bin
- replace the /boot/kernel.img in the SD card with ~/src/tools/mkimage/kernel.img
- replace the /boot/start.elf in the SD card with ~/src/kernel/firmware-next/boot/start.elf
In the big partition of the SD card (/root):
- replace the /lib/firmware in the SD card with ~/src/modules/lib/firmware
- replace the /lib/modules in the SD card with ~/src/modules/lib/modules
- replace the /opt/vc in the SD card with ~/src/kernel/firmware-next/hardfp/opt/vc
Now your SD card contains the new image. Safely eject the SD card, plug the touch controller to your RPi, boot it with the SD card, run startx, and check that you can move the cursor.
Once I was in the desktop, my touch input was working but it needed to be calibrated.
To calibrate, you need to install an X input calibrator and some dependencies:
$ sudo apt-get install libx11-dev libxext-dev libxi-dev x11proto-input-dev
$ cd ~
$ wget http://github.com/downloads/tias/xinput_calibrator/xinput_calibrator-0.7.5.tar.gz
$ tar -zxvf xinput_calibrator-0.7.5.tar.gz
$ cd configure
$ sudo make install
Follow the instructions on the screen. After calibration you should see something like this:
Calibrating EVDEV driver for "eGalax Inc. USB TouchController" id=8
current calibration values (from XInput): min_x=1938, max_x=114 and min_y=1745, max_y=341
Doing dynamic recalibration:
Setting new calibration data: 121, 1917, 317, 1741
--> Making the calibration permanent <--
copy the snippet below into '/etc/X11/xorg.conf.d/99-calibration.conf'
MatchProduct "eGalax Inc. USB TouchController"
Option "Calibration" "121 1917 317 1741"
Option "SwapAxes" "1"
For Raspbian, you have to create the file:
$ sudo nano /usr/share/X11/xorg.conf.d/01-input.conf
Add in this file the content above, starting with Section "InputClass" line and save the file.
Note: Make sure that you don't have sections like MatchProduct "eGalax Inc. USB TouchController" in other files from /usr/share/X11/xorg.conf.d/ folder (highest number files are processed last).
Now touchscreen should be calibrated and after reboot it will keep the settings. Yolu can run xinput_calibration again in order to have the pointer to the desired points. You can update the numbers given by the xinput_calibration utility in the usr/share/X11/xorg.conf.d/01-input.conf file in order to have the best calibration at boot.
