Bubbles move from the bottom to top making an click impossible. I have disabled the touch screen and it works fine after that but as soon as we reboot it enables again. I need a permanent solution to turn off touch. I've done a lot of trouble shooting with no luck.

Right click Start and select Device Manager,
Expand Human Interface Devices,
Right click HID-compliant touchscreen,
Select Disable device.

Problem is it enables at reboot.

I also Factory restored to see if it was software and same issue. So I think the hardware is bad. Now can I unplug touch? Or is this a whole part replacement? Warranty of course is over so no help from HP. Seems to be a common issue of recent that has plenty of forum requests but no other solutions available then disable in Device Manger (again a temp solution)...

I am looking at this laptop and have two questions:


1-If I re-format it to run Windows 7 Pro, are there drivers I can download from Dell?
2-how many external monitors will it support at 4k resolution of 3840x2160?
I would like to have a laptop that will run two external monitors at 3860x2160.  Can you tell if this one will do that?

We are trying to connect to a Epson EB-2265U that has a wireless connection. On a Windows 7 laptop we get error - "Windows received information from the projector that it cannot interpret" when using the Connect to a network projector.

However, on a Windows 10 laptop it finds the projector automatically and manages to project.

I have a CD with some projector software but I wanted to see if there is a way Windows 7 can connect just as Windows 10 does without drivers etc. This would be helpful for visitors so that we don't ask to install software on their laptops to enable projection.
Had Office 2007 installed on a Win Pro 7 HP desktop.  At that time I was able to open up outlook on the main display and drag it over to the other monitor.  All worked fine.  Then I upgraded to Office 2013 and now when I try to drag over the outlook window to the other screen I can only see some of it.  It shows the header and some of the side but nothing in the middle.  It's blank.  If I click around I eventually can see more of the screen and it is usable but I have to do this everytime.  Any ideas?
I installed windows 10 creator upadate in my ACER ASPIRE U5-710 TOUCH SCREEN. Everything went well but the touch screen which is not working anylonger.
In the attempt to fix the problem, I tried in sequence:
1) windows hardware troubleshooting - no result
2)  I searched for the HID  touch screen driver in device manager  but there is not a HID touch screen driver; by the way,  all drivers worked  properly and were up to date (no yellow sign)
3) I downloded and installed all drivers suggested by Acer, in particular VGA drivers and Chipset , hoping that the touchscreen was embedded there - still no result
4) lost any hope. Ii decided to return to Windows 10 and I disinstalled Creator Update by using the proper windows function to return to the  previous  system -   but now the touchscreen did not work even in the  old system
5) so I  contacted ACER and they were only able to suggest me to restore the whole system to the initial condition by using the ACER recovery utility, wich the kind of suggestion that even my  5 year old  nephew  could give me. Yes, of course, this would probably work, but I want to find a true solution.
Is there anyone who coudl suggest a possible solution or at least something to try that I did not  think of?  Thank you in advance
Hi, I have a Macbook Pro and iMac on my desk, and they obviously both have their own keyboards and trackpads.

I am wondering if it is possible to do the following two things:

01 - control my iMac using my Macbook (keyboard and trackpad) so that I don't need to use the iMac keyboard and trackpad?

02 - swap and flick my Macbook screen up onto the iMac screen if i need a larger screen and flick back again (etc)

A few things to note:

- i am using the new Macbook Pro so it only has the USB C ports
- the iMac is one year old and has all of the usual ports

Thank you in advance for your help.
I am having an issue with my monitor and Adobe products in general.  I realize it is probably the software and probably is related to other products as well but some are working and others are not.  The issue is that I have a USB-C port on a new Dell XPS 13 Ultrabook.  I have it extended to a USB hub with 3 USB 2.0 ports.  One port is plugged into a Dell 27 in monitor with resolution of 1920 x 1800, The Dell Ultrabook is set to 3200 x 1800.  The Dell Ultrabook screen looks fine.  The Dell 27 in monitor looks bad with some programs. It looks like it's really displaying at 800 x 600.  The program screen is way too big.  It needs to be sharper and smaller so it looks like the Dell Ultrabook screen.  I have read that there is an issue with Adobe where the program tells the computer it's a size it's not.  Can anyone assist?
It has come to our attention that some remote control software we use has a conflict with the Matrox video driver.  (When we connect remotely to a computer running a Matrox video driver, it is very slow.)

How can we replace this driver remotely?  We will only get one shot at this since, if something goes wrong, we're doing it remotely...

If we revert to the "VGA Standard" driver, will it look like the screen (i.e. have the same resolution) when we go into Safe Mode?
Windows XP Display Settings Multi Monitors loses settings during restart.  Is there a setting in the registry that can be modified so that XP retains these settings rather than resetting each day.  Drivers are up to date.

What kind of adapter is needed to connect two external monitors to a Lenovo Yoga 720-131kb laptop?

Is it possible to do this without having to purchase a port replicator? If so what kind of adapter is needed?
Hi Experts,

i have tried looking on-line but have so far been un-successful. I need to get a guide which can be given to users to help them setup monitors. not with regards to the physical setup but more so the software side. I don't fancy writing the document myself as i would have to include all the following scenarios:

Scenario 1: you have 1 additional monitor that you would like to connect to the laptop to duplicate or extend the display.
Windows 7
Windows 10

Scenario 2: You have 2 additional monitors that you would like to connect to the laptop
Windows 7
Windows 10

Scenario 3: You have 3 additional monitors that you would like to connect to the laptop
Windows 7
Windows 10

is there any content online which would answer these questions in a generic way as i know that display settings can be a pain but the common issues here are users having issues getting the monitors the correct way round or resolution / size of icons are incorrect.

worst case scenario i will have to bring together several articles online with screen shots etc but was hoping there may already be a john and janets handbook as such on this.

thanks in advance,

Hello experts I've been provided a laptop from my company.  Its a Dell Latitude E5570 with a Intel HD 520 Graphics card, driver is up-to-date, which connects to a Dell DisplayLink.  I cannot get it to disconnect the built in display when connecting it, it always has three displays.  Not sure what to do, I've gone through the display driver properties, display setting in windows, switched cables, docking stations & monitors.  I've exhausted all my ideas.

Oh yeah its got windows 10 pro

Thanks in advance.
Hi Guys,

i wanted to purchase an Intel Compute Stick to run a some basics, powerpoint, VNC software, AV. nothing intense!

i wanted it to be windows 10 pro but none of the sticks come pre-installed with it. you can purchase an upgrade through the Windows App store but reading online many people have had issues with this. and also many people have had issues with the stick breaking and then having to re-purchase the licence for the 10 upgrade on the replacement unit due to no product key being given.

so does anyone have hands on experience with upgrading these to 10 pro? are they reliable?

does anyone know an alternative which would also run windows 10 pro out the box?

what do i need the stick for: to plug into a monitor and be used as a display board. need to be able to remotely connect to this on our domain to up-date the slideshow or information being displayed.

all help appreciated,

Three laptops are having issues when a second extra monitor (BenQ) is plugged in via HDMI. Testing similar monitors on the ProBook 450 G3 seems to work completely fine (models of laptops having issues listed below).

1.      HP ProBook 450 G2
2.      HP ProBook 450 G0
3.      HP ProBook 450 G0

Won't work with two BenQ monitors plugged in via VGA (GL2450-T) and HDMI (BL2405PT). The VGA monitor works, but the HDMI monitor will say "No cable connected" despite it appearing on the Screen Resolution menu as a "BenQ LCD".

We have updated the BIOS and GPU drivers with no luck. We have successfully plugged the BL2405PT monitor in via VGA and HDMI on its own, which have both worked. (Have yet to test the monitor on its own via HDMI ,to rule whether it's an issue plugging in via HDMI, or an issue with multiple monitors).

We're going on-site now, so will provide more details soon.
The monitor is Apple Cinema HD Display (23 inch diagonal)
Trying to connect it to recent model MacBook Pro with 4 USB-C ports

Here's how it's connected:
  • The USB from the "Octopus" connector goes to a USB2 to USB-C adapter, plugged directly in.
  • The DVI from the "Octopus" connector is first going to a DVI to Mini Display Adaptor, which worked fine when plugged into the Thunderbolt port of an MacBook Air
  • This adapter goes to a ITD ITANDA Thunderbolt  to USB-C adaptor, directly plugged in.
The power light on the Apple Cinema HD Display is on, the USB is plugged in, but the computer doesn't recognize the display.

Do we have the wrong Mini-Display port to USB-C adapter?

Is there a way to attach this second monitor?

I have a display port on two computers that I need to quickly switch between.

I'm looking for the simplest solution to this issue.
I have a Samsung TV and an LG TV on the same computer as monitors. 32" 1080p

As long as I have the LG TV turned on, even though the picture itself has now turned completely black and the TV is worthless, the Samsung TV is crisp and clear and images are smooth and pretty.

If I turn off the LG TV, the Samsung gets grainy and washed out and looks really bad.

When I turn on the LG, the screen flashes that it is set to 60Hz when I turn it off, the screen flashes 60p. I don't know what those values represent.

When the LG is on, the TV setting on the Samsung offers me a Dynamic Picture mode and that is the setting.
Once the LG is off, the Dynamic isn't even an option, but Entertainment and Standard are the only 2 options, and Entertainment is a tad better than Standard, but images are still unacceptable.

I'm describing images, but fonts are also choppy. Just bad overall picture.

I have adjusted the resolution, the settings, everything, and I can't find the problem. The problem isn't with truetype or fonts, because images are horrific and have nothing to do with fonts.

I've reset the picture to default settings on the Samsung. I've altered color, contrast, sharpness, etc. etc. So please don't suggest that.

Any solution to this problem? I've googled and found a similar problem and the guy just ended up taking the TV back and getting a new one. Not an option for me.

Using XenApp 6.5 r07 / Citrix Client 4.7
Running Windows 7 on the laptop with a Lenovo docking station
2 - 1920 x 1080 monitors connected to the docking station.
When I open a Citrix app (Putty, Notepad) the window cannot be resized (no arrow indicators on window corners) and when I attempt to move the window it moves one half an inch. Can't move to another monitor. No tool tips will display for applications within a Remote desktop connection.
If I remove the laptop from the docking station, moving / resizing / tool tips work.
If I only have one monitor plugged into laptop directly, it works.
Citrix admin says Citrix server Display memory limit / ICA Graphics is set to max at 131072KB.

I have checked all blogs and Cittix support and cannot find the resolution for this.

I am having problems with my Benq BL2400 monitor. Windows 7 doesn't detect it and offers me horrible resolutions to use.

Any ideas on how to make Windows 7 detect my monitor?
I have a Sapphire 280X Toxic graphics card that is not showing any picture on a Benq BL2400 screen.

When I connect the GPU to my TV via HDMI, it shows a picture like it is supposed to when the PC boots. But Benq BL2400 doesn't have HDMI. So I connect to Benq using a cable with DVI in one end (for the Benq screen) and HDMI in the other end. That doesn't work. I then connected a cable that is DVI in both ends, and that didn't work either.

Seems like my Sapphire doesn't like my Benq screen,

Is there any trick I am missing to get it to work?
Hi, I have a docking station that I've used for three years.  It has not caused any problems.  The hardware that evolved over time is the latest purchase of a Latitude from older model to new model.  Also, I have went from one monitor to two monitors with an extended mode screen setup.  The Dell Latitude docking station has two display port connections on the rear of the dock.   The latest setup has been holding up well with Windows 10 until the last month.   I've always placed the computer in sleep mode to eject from the dock environment and take it on the go.  However, the monitors fail to display lately when I redock unless I flip open the laptop screen.  Then one screen pops open while the other display remains dormant.  I can't get the dormant screen to activate unless I shutdown instead place in sleep mode.  Then turn on the computer and the two screen finally pop up after logging on to Windows 10.  Is this Windows 10 or hardware?  I'm leaning towards Windows 10 but I have no idea how to fix it.
Finally, my Dell Latitude e5430 battery went bad after 5 months.  Any recommendation on Dell adapters?  Does it not like the old Dell adapters?  Why would the battery go bad so quickly?

Hi experts,
 I have a laptop and a monitor connected to a docking station. The monitor displays :
There is no signal coming from your computer.
Press any key on your keyboard to wake it up.

Then it says entering power mode

I replaced , cable , monitor , docking station and same issue.

Any ideas? It's connected to a dell laptop Inspiron 7000 series
Hi Expert,

Hello, I am needing assistance with taking apart a Dell S2209Wb monitor.  I have a replacement power supply board that I need to install however I can only get as far as removing the 4 screws behind the monitor stand.  There seems to be no way to get the bezel off, there are no guides or grooves to use as a starting point and it simply won't come off.

Upon searching online, there are absolutely zero tutorials on how to do so with this particular model.  All other Dell model tutorials are immaterial since this model seems to be special and does not go along with the general rule of prying off the bezel.

Can anyone provide any assistance on this?  I need detailed steps and illustrations or video is a major plus.
