Latitude 5285 bottom 1" of touchscreen issue

I've experienced the same thing on two different 5285s in the last month. Bizzare to say the least.

I have 10 of them in my office and 2 of them so far are experiencing this issue.  They are development machines and sit on desks.  They weren't being transported or tossed around.  Almost like it happened out of nowhere.

Saw reports of the wrong resolution.  Another post here said:If your resolution is 1980X1280 (vs. 1980x1080) the bottom 200 pixels do not respond to touchscreen input, this appears to be a bug in DELL firmware.

But this doesn't seem to help.  Can set the resolution lower, but then the screen is shorter than the display and it doesn't help.

Very weird.

the exact same thing started happening to my laptop. Since buying it about 2 months ago, I've only used it for about 20 minutes. I powered it up today to begin using it and like others have indicated the bottom 1/2 to 1 inch isn't working. I tried to calibrate the screen, but it wouldn't read my touch on the bottom cross hairs. I wonder if a windows update is causing the issue? Hopefully someone from Dell will respond or others have found a fix?

The resolution being the issue would be quite odd as the native resolution is 1920x1280. I contacted Dell and ran a few tests they suggested with no avail. I will post their test suggestions here in case it may help anyone else.

Suggested testing from Dell Online Support:

1) Has the system suffered any physical/accidental damage?

2) Run ePSA

I did reach out to Dell and they sent me those test procedures to go through. After none of those tests fixed my issue, my issue is now currently pending parts and a technician will come by to replace the part(s). 

I wonder if it is soldering problem for the chip. Similar to LG G4, overheating causes bad soldering. Maybe should unite together to ask dell for repair or replacement..

An update for everyone:

Since my unit was still under warranty, Dell sent out a technician to replace my screen and ribbon cable. It now works as it initially did. I ran HWinfo and it shows to be the same part number as the one that became defective so I hope this one doesn't exhibit the same issues down the road. We'll see...

If yours is out of warranty, the only option I can see is possibly to buy a replacement screen from partspeople.com or eBay. =/

Clearly not software issue here! I tried all updates, Windows reset etc.

Dell Support! whats the solution? Besides returning for Screen Replacement.

Same issue here.... Problem just appeared out of no where a month ago or so!  This tablet has not been dropped or damaged at all and looks new. Most certainly not a software issue or driver issue. It has been working fine since the day it was purchased.  Dell should cover this defect.  As it turns out I am just a couple of months out of warranty when this issue was first detected. 

Does anyone know a fix? I bought a replacement screen/cable and still the same issue! :(

All -

Came across this thread while troubleshooting my Dell Latitude 5285 (refurb from online reseller < 6mo.).

Symptom: Prior flawless function of touchscreen w/Dell Active Pen 556W, started experiencing issues with Active Pen usage with landscape mode (tablet/non-tablet mode) touchscreen's lower 1" horizontally where tap signal failed to register while some areas within (lowest 1" horizontal) zone would register long press with Active Pen.

Attempts to reset/calibrate touchscreen including uninstalling Dell Active Pen drivers/SW and then reset/calibrate touchscreen (including full edge calibration), failed for Pen usage; not Touch.  Went to Dell Support site to successfully update all device drivers including BIOS.  Re-attempted calibration unsuccessfully.

Troubleshooting led to using a different stylus (ZSpeed Active Stylus for capacitive screens).  When using 'touch end' of stylus, lowest 1" horizontal zone would register accurately.  When using 'pen end' of stylus w/Pen turned on, lowest 1" horizontal zone would register accurately as well.

Will replace batteries in Dell Active Pen to test further.

Current findings indicate touchscreen HW and SW are functioning as expected.  Will replace batteries in Dell Active Pen to confirm successful test results w/ZSpeed Active Stylus.
