XPS15 9550 - Slow scrolling and page loading in Chrome on external monitor

Q: XPS15 9550 - Slow scrolling and page loading in Chrome on external monitor

I'm using an external monitor that scales at 100% (1440p 32"). The internal monitor is 4K, so scales at 250%. In a day I might need to plug and unplug the external monitor (from HDMI port) several times, and after a few times, it seems to struggle with switching between the scaling of external and internal monitors. On Chrome, for example, scrolling sometimes is noticeably lagging, and new pages will flash multiple times as they are loading. Moving Chrome over to the internal monitor (with 250% scaling) and everything seems to work fine. Restarting Chrome doesn't change the issue. A whole reboot is necessary.
I would guess it's a driver issue. I also have light screen flickering, though I only notice it when not using the external monitor.

It's worked out well for many of us in the past.

Hi all, 
can anyone tell me or point me to a source that will give me clarity on the question if the GTX960M in the XPS15 9550 does support NVidia G-Sync via the USB-C/TB3 Port? Of course I would need an adaptor from USB-C to DP if the Screen only supports DP as Input but the question here is about the G-Sync capability of the XPS15/the GTX960M. 
Thanks in adance

A:XPS15 9550 - NVidia G-Sync on External G-Sync Monitor

According to nVidia, the minimum GPU for G-sync is the GTX965m.
The notebook mainboard must also support G-sync  -- something I suspect the 9550 does not.

I have an ASUS G75 running win8.  I have lots of RAM and a good internet connection (I get about 38Mbps down and 5 up).  My problem is page loading.  It can get painfully slow, specially if the page is ad heavy, but even pages that are short on ads can take 20-30 seconds to load.  I suspect I am having a problem with either Java or Flash, but don't know how to check further.

When scrolling in Windows 10 using the trackpad of the XPS 15 9550, sometimes scrolling is extremely slow. (You can scroll, and physically sit back and wait for the scrolling to finish.)
I noticed this in windows which contain a treeview (e.g., the left pane of the Windows explorer, foobar2000 album view), and not (yet) in other windows (e.g., Chrome, or the right pane in the Windows explorer).
When plugging in an external mouse and using this to scroll, this does not occur, indicating a possible issue with the trackpad drivers or settings?
Is anyone else experiencing this issue?

I am currently experiencing a problem that is driving me nuts. Whenever I go to a web page on Chrome, and reading it, the browser will suddenly jump (scroll) to the bottom of the page. It does this un-commanded. It does this without me touching either the mouse, nor the laptop surface. The laptop is a Lenovo Y580. It makes it almost impossible to read a webpage without using my mouse to go back to where I was reading. What am I doing wrong? Thanks for your assistance.

Hi All,
I have a XPS15 9550 laptop (with the 1TB SSD option)  The SSD is installed in the conventional storage bay.   I ran the intel rapid storage app and it implies there is another SSD bay inside, but currently empty.

Here's a screen grab.  I think the empty internal port is for a mini SSD 'stick' type hard drive.  I think it's an "M.2" type slot but I'm not sure.   Would one of these fit?

I was so pleased that I could finally afford to buy a top of the range laptop.
After years of building my own PCs to a budget, price was finally no object.
So £1600 later, I'm happy, right? No. I'm not. This computer is a pile of *** and I hate myself for having parted with so much money for such a poor product and, more importantly, such poor service from Dell.

Hi,This is kuiyoung. I had service few month. I forgot when it was. That time your technician came to office and changed motherboard. But when Im using it, suddenly it starts flicking and get error message that pc went to wrong. It's been two weeks. Strongly I think this one has problem and I don't wanna repair anymore. Because as you can see, I requested several times to repair this notebook. I'm really sick of it. I really don't think this one has virus. Thus I don't wanna install any program to wasting my time. I hope that you understand my situation. Thus I wanna refund or change new one. If you refund I would be more happier than change new one happy. Because after changing new one, same problem, I won't call you guys again. I will definitely buy other brand. It was my first time to buy Dell laptop. Really disappointed. I hope other people won't make same problem like me. I used to use other brand and never had problem.

Per Dell policy;* A refund is only possible if requested inside the FIRST 30 days from the original invoice date.* Any system exchange after the first 30 day will be a refurbished, not new.At this point, all we can do on this Forum is troubleshoot the flicker issue.

We're encountering scrolling issues with Excel 2013 (and 2016).
What we mean by that is graphic distortions (blocks of black) appearing on the worksheet during the scroll action.
It happens almost exclusively on the externally attached monitor.
Even after the scrolling action is finished the blocks of blacks will persist and will obscure the data in the cells. Generally only opening the worksheet anew will correct the issue (until scrolling is once again initiated)
This is on a new Dell XPS 15 (9550) running Windows 10.The monitor is a Dell U2717D connected via the HDMI.
We've done quite a bit of troubleshooting but before describing in detail we wanted to know if anybody had seen something similar?

I keep getting a DRIVER_POWER_STATE_FAILURE blue screen right after Windows 10 has booted.
It always seems to happen when I move from network to network, eg. If I am working on my home WiFi network and then take my laptop to my work place I will get the DRIVER_POWER_STATE_FAILURE blue screen and vice-versa.
The machine will boot fine however if I've not travelled to new network.
Any ideas, it's a really annoying problem.


You will need to find out some more info somehow.  One way might be to check the BlueScreen message with the square barcode.  On the bottom of the text it might mention some file involved.
For instance, when I had an Intel Dual Band Wireless AC 3165 card installed, I was showing a problem with Netwtw04.sys.
Are your getting any dump files as either Memory.dmp or mini-dump files which would be in a mini-dump folder?  Do you know how to set your system to use the smaller mini-dump files if you have not already done that.

Hey everyone,
Unfortunately, the port on the 9550 is HDMI 1.4 (max resolution of 1920x1080 for external monitors). I recently purchased a Thunderbolt to HDMI 2.0 adapter in an attempt to get around this, but I have not been able to figure out how to get any higher resolution so far. According to the NVIDIA control panel, outputs to both the screen and the HDMI port are being handled by the integrated graphics, which I suspect might be part of the problem. Still no luck after changing the default GPU in the global settings to the NVIDIA processor.
Has anybody had any luck getting their HDMI output set to run from the NVIDIA GPU?
Note: This is the model with the FHD screen (1920x1080 native resolution).

My new XPS 15 9550 does not seem to support external monitors in [email protected] correctly.I have updated all of the drivers and BIOS to the very latest files available on the Dell support page, including the newest Thunderbolt 3 driver and firmware.I have managed to connect the laptop to the monitor ([email protected]) using a usb-c/tb3 to displayport adapter (kiwibird's). It works (and image is fine), however when the monitor goes to standby, it's almost impossible to wake it up again (I have to unplug the monitor, turn it off, turn it on again, and plug it again...).When the laptop is connected to the same monitor using hdmi ports (1.4), I am not experiencing any trouble (wake up does work), but I'm stuck at [email protected] (as expected).I have contacted Kiwibird support, they've told me the standby issue is a known issue related to the Dell's thunderbolt 3 driver when Dell XPS 15 (9550) is connected with 4K monitor. I have not found a confirmation so far (on the forums) that it's indeed a software issue, and I'm still wondering if the adapter is working correctly.Any thoughts ?Maybe another cable and/or adapter brand, either DP or HDMI, is working correctly ([email protected] and standby/wakeup works) ?Thankstranb3r

I just took delivery of the system a few weeks ago (coming from a 2012 XPS 17 l702x that's showing its age, even with 16GB ram), and no issues with it of any importance but I do have a question that I'm very curious about. The Nvidia adapter (GeForce GTX 960M) is supposed to be a selling point, right? So why is it when I open the control panel to see what programs it is used for, it is basically only Chrome and all other programs the Intel with no option to choose. 
Am I missing where to change a setting to allow me to choose to at least have the option to use it?
On a positive note, the laptop is a peresonal computer but went with this one for muscle to run some CPU intense programs, like autoCAD for work. I like lots of visible "acreage" on the screen so the 4k monitor is a great change from the HD of the l702x. I have been going back and forth chatting with Dell support, having a hard time getting through the flow-chart responses to try and ask a simple question of if the system will extend the display to a second screen in 4k, and is so, what will I need hardware wise.
The final result from tech support was I need a  Thunderbolt 3-DisplayPort adapter and get a 4k device with DisplayPort input ( Turns out, that's not cheap), as the onboard HDMI output does NOT support HDMI 2.0. This is all while he knew I had (have) a Dell DA200 adapter.

i could not manage to extend my laptop dell xps 15 9550 through TB15 dock to two monitors (U2717D) in 4K. The max resolution that I got is 2K on each monitor.
I tried all the combo with mDP, DP and HDMI, the best I got is 4K for 1 monitor.
The techcenter assured me that using mDP and DP, TB15 can deliver 4K in dual display at 60hz and with HDMI 4K in dual display but at 30hz.
I got nothing on these from intel HD graphics control panel but only 2K at 59/60hz (which is the max available).
However, on the dell website, the TB15 do deliver 4K in dual display at 60hz.
If anyone managed to configure the 4K resolution in multiple displays, extended desktop (as display mode), please let me know

A:XPS15 9550 + TB15 cannot display 4K in dual displays

As a workaround... Try disabling Switchable Graphics in BIOS. Part of the problem for me on Dell Precision 7710 (AMD/Intel video) had to do with unable to display 3 external monitors concurrently with Laptop's monitor (for total of 4). I made sure I was running latest firmware of laptop and followed the docking station's driver/firmware updates (found elsewhere here), and I have far fewer issues. I also found that the hub's Realtek GB Ethernet only ran at full 1GB speed when the power plan for Winidows 10 was set to High Performance.

Just 15 months ago I bought a new Dell XPS15-9550 direct from Dell. The top model (i7 processor, ultra-HD display). Expensive, but a quality laptop, with I assumed many years of life ahead.
Then a month ago the battery (a Dell type 4GVGH 84 Wh 11,4 V) started expanding, pushing the touch pad up and out of the case. A little research on the net showed this is a known problem with this battery. I demounted and disposed of the battery – I wasn’t going to risk a fire or worse.
I knew that Dell only offers a 1 year warranty on the battery, so I knew I would have to pay for a replacement battery. But I naively assumed I could get hold of replacement parts for an expensive 15 month old laptop. After all the 9550 was still being sold on the Dell site until very recently.
I now discover that Dell no longer offers batteries for the XPS15-9550, nor are they available from anyone else here in Denmark or in Europe. I can buy a “copy” from China, but I’m not comfortable with that.
I can still use the laptop with external power, but . . .
Dell – this is not acceptable. 

A:Dell XPS15-9550 battery (4GVGH) expanding

Dell doesn't sell batteries for systems where the battery is internal - it's not considered user-replaceable.  They will replace the battery but you must contact them for an out-of-warranty repair estimate - the battery is sold only with the labor to replace it.

The Microsoft Designer Keyboard and Mouse operates very intermittently. I notice this most frequently when the XPS15 dims or turns off the display but it can also happen spontaneously while I'm moving the mouse pointer around. I think both mouse and keyboard stop working at the same time. I have found that sometimes, if I use the trackpad to move the mouse pointer around, the Designer mouse starts working again. If not, it appears to not update the mouse pointer indefinitely or until I reboot the XPS15.
I've spent time pairing and unpairing the mouse. Pairing pairing fails maybe 10-20 % of the time.

Hello everyone,
I have my xps 15 for a few months now but still I haven't found any solutions for my problems.
1st Problem:
Whenever I boot windows (or sometimes after energy-saving mode) the keyboard just doesn't work at all. I already tried waiting for a few minutes and smashing every button on it, nothing made the keyboard working again. To solve this I have to restart the computer after that it works.
2nd Problem:
Whenever I close it while running, it just won't "wake up" again. The power-button-light lights after opening the laptop but the screen stays black.
3rd Problem:
Sometimes when I want to boot windows it just won't. I see the "DELL"-logo then the few blinks at the top-left corner of the screen (A white '_' blinks 3 times) and after that nothing happens.

So these are my problems. I hope somebody can help me with these because it's very anoying if I have to start the computer twice so that it works like it should.
If you have any more detailed questions please ask them.

I have a Dell XPS15 9550 with 1TB Hard disk, it is the basic XPS15 Model from 2016. Purchased from Amazon in August 2016.
It makes a noise. Listen to attached mp3 sound file.
The noise happens at 5-9sec, 25-33sec and 45-1:03secs during the recording. It repeats generally lasting 18seconds duration. This was when the laptop is switched on, and only running windows 10, no other programs. 
I used a sound recorder on my iphone and when the hiss noise kicks in it reads 58db compared to a normal 45-50db range without the noise.
It is a hissing noise coming from the bottom right corner(facing the laptop keyboard) - where the hard drive is located.
No one at dell support can listen to this file to tell me if it is normal noise or not. I have had dell support remotely update all BIOS and chipset files. We replaced the hard drive for a new one and it makes exactly the same sound. Its not the sound card or speaker. Its definitely the hard disc spinning. Dell support said maybe it was a "capacitor" and it should be sent in for a motherboard replacement???
Please tell me I am not going mad. It is a noticeable noise, you can hear it throughout a large room. When watching a film etc.
Please some answers!
1) What is the noise?
2) Is this normal?
3) How do I get rid of it?
4) If I cant, which XPS15 variant does not have this noise? Is the i7 with SSD quieter?
Many thank you for your help.

A:XPS15 i5 9550 2016 Noise coming from hard disk?

Some hard drives have wear-leveling algorithms that move the head stack assembly at random when the drive is idle -- so they're not flying over the same position on the disc for long periods of time.  If you've had the drive replaced and the replacement is from the same manufacturer, that's probably what you're hearing.
If the noise is bothersome, replace the hard drive with a solid state drive -- which will make no noise at all.

Everytime need to set up display as 2 display, HP as Main and laptop as extended. Then every 5 to 6 min, the system reverted back to single display by first blanking the screens.
Reset the display by clicking detect and the laptop screen come back alive, and then after 5 to 6 same thing happened
Talk to Geek Squad. Change the cable, update the Intel HD graphics drive, reinstall and uninstall. Still happening
Update BIOS to the latest available still not solve the issue
Even after letting it in single display mode, the blanking keep continue. It is very annoying and distracting while working.
Any one encounter the same issue.  Please share the resolution
Thank you

A:Dell XPS 15-9550 with External Monitor HP2311xi - keep getting blank screen on and off -

I am having the same issue with my XPS 15-9550 with Nvidia combined graphics connected to a Dell UP3216Q external monitor.
Typically when interacting with apps, i.e. scrolling in MS Edge browser, the external monitor blacks out for a few seconds. It is very intermittent, and tends to occur several times within a 30 second period then it will stop for a while. Acts like bad HDMI cable connection. I have the same issue with multiple cables, although it could be the receiving connector on either the laptop or the monitor.
Have changed drivers on both the Nvida and intel adapters with no change in behavior. Changed resolution, frame rate, etc.
The problem renders the system unusealbe and I will have to return both the laptop and display if not resolved soon.

I recently purchased an XPS 15 9550 with i7, 16 GB RAM, 256 GB SSD, and GTX 960m dGPU that I have connected to a 27-inch QNIX qx2710 2560x1440p external monitor. I have this connected through a Cable Matters USB-C/Thunderbolt 3 to DVI-D adapter and cable.
The monitor and everything seem to work fine at 60hz, except for every time I unplug, turn on, or restart the monitor/computer the first five or ten minutes of use is plagued with constant screen flickering and flashing. After ~five minutes the monitor seems to stabilize and will only rarely have a single screen flicker. 
I have read other forum threads describing similar issues with different monitors/cable setups and that there is likely an issue between the wifi card and thunderbolt port. The common recommendation is to turn down the wifi output percent to 75%, however the Killer wifi card on this computer does not have an option under advanced settings to turn down the power output. Has anyone had any luck doing this on a recently purchased XPS 15 with the Killer wifi card?
The cables and adapters are new and the BIOS and all drivers are up to date. Other than the wifi issue, does anyone have suggestions or solutions to this screen flickering problem?

Hi all,
I got my new XPS 15 9550 2 days ago. Everything went fine at first but tonight when coming back home the laptop won't turn on. I tried the following (both with AC adaptor plugged in or not)
If I press power button the battery status lights blinks 4 times white and é times orange repeatedly.
I tried pressing power button for one minute - nothing.
Pressing Fn key and power button - then the keyboard lights turn on  for about 5 seconds then turn off, and same blinking of the battery status lights as described above.
Any idea what to do ? Dell technical support doesn't seem to work on week end...

I had my setup working perfectly on Arch Linux before updating my bios. The dock could be plugged and unplogged at will without crashing. After updating to the latest bios (To get the Intel ME vulnerability patch) it doesn't work anymore.
Connected on the dock:
One 1080P screen (HDMI)
Another 1080P screen (Display port)
USB mouse and keyboard
Ethernet cable
3.5mm jack to sound system

Setup that worked
Bios: 1.2.18
Kernel: 4.10.6-1-ARCH

Setup that crashes
Bios: 1.2.25
Kernel: 4.10.6-1-ARCH
Kernel: 4.10.13-1-ARCH

Expected behavior
Connecting the dock when the laptop is powered works.
Connecting the dock when the laptop is turned off and booted works

Actual behavior
Connecting the dock when the laptop is powered crashes the system
Connecting the dock when the laptop is truned off works, but mouse and keyboard don't work.

Anyone has pointers on how I could resolve this issue?
Thank you very much.

I recently update my bios to the latest 1.4.0 version. Now after entering sleep mode (due to closing the lid) and resuming my disk (/home) is not populated correctly. I'm using linux debian 9.
I use an internal nvme flash disk as root filesystem w/o HW encryption security and that disk is resumed ok. On a secondairy ssd disk using hw encryption as which serves are my home partition, after bios update this partition is not resumed correctly. The disk is there but the encryption password is not set so the disk will not work. After reboot and typing the password the disk is usable again.
On the previous bios 1.2.14 this setup was working fine, when upgraded to 1.4.0 this started to fail.
In the release notes of 1.4.0 there are bugs fixed with password security for encrypted disk so I assume this is why behavior has changed, but this introduces bugs on my system. Is there anyway to fix this? or a newer version of the Bios available?

Running Win.Xp Pro 64 - Page scrolling is slow and jerky especially on IE.
Looked at all the usual answers from Mouse to smooth scrolling, but fix eludes me. Where am I going wrong, more detail available if needed.

Hi Peter,


Running Win.Xp Pro 64

I take it that all of your drivers are up to date. Getting drivers for XP x64 can be a bit of a nightmare due to lack of support for x64 XP. There is better support for 64bit OS in Vista and above.

Can you post your full specs. Download and run Speccy for me. Once the program has gathered the required information, go to the top of the Speccy window and do File>Publish Snapshot. Click Yes when prompted. Now copy and paste the URL address that it gives you to your next post.

When did you first notice the issue?

I am trying to resolve the slow page scrolling problem that appears after the reinstatement of windows.

I downloaded drivers, directx and silverlight plugins and I also deactivated auto scrolling from browser's options but the problem persists.

Can anyone help? The only problem indicated by the device manager is an exclamation mark next to the VGA device but I can't find drivers for it.

My PC is a Compaq Presario 1500 notebook, P4, 256 RAM with ATI Mobility Randeon 7500 accelerator.

Thanks in advance
