I have a new Dell M3800 Laptop, screen resolution 3200x1800, and an external 1080p Samsung monitor.
No matter what I do, the external monitor is slightly blurry.
- Laptop: Dell M3800 (the 3rd one that is listed at $2484)
- Vid Card: Nvidia® Quadro® K1100M, w/ 2GB GDDR5
- Monitor: Samsung PX2370
- OS: Windows 7 Pro
- Connection: HDMI. And it's not the cable - I tested with another HDMI cable, no difference.
- Desktop Background: is at least 1800 resolution, set as "fit" not stretch.
This is a breakdown of how settings affected the two displays.
Display Mode:
- Duplicate mode: adopts the lower resolution for both.
- Extend mode: see below
- Projector only: Samsung display is same as in extend mode
Regardless of settings, these issues persist for the Samsung display:
- Some entire lines of text are blurry/shadowed while other entire lines are fairly clear. ------> running ClearType made almost no difference.
- Display is expanded, edges go off sides (e.g. only half taskbar visible) ------> Scaling aspect ratio to 66 (both vert and horiz) brings it back into frame.
There are only 2 ways that the Samsung display changes, nothing else is alterable with any settings:
Background size: changes depending on laptop resolution if laptop is set as primary.
- When laptop is at max resolution, Samsung background looks "zoomed in."
- Lowering the laptop resolution to 1152 and 1080, Samsung background zooms out until normal size.
Text/object size: changes only by scaling text, regardless of primary or resolution.
Laptop display
When laptop is set as primary, changing its resolution or scaling text have the expected effects on the laptop display.
But when Samsung is set as primary:
- If laptop is at 1800 resoluation: the laptop background image is sized like a 1080 image on a 1800 screen (a small background image framed by black a rectangle in center of black background).
- Bringing laptop down to 1080: background image is framed normally, and everything is larger, but I lose all benefit of QHD resolution.
And even then, the Samsung monitor is still blurry.
It's overall worse than my 5 year old laptop looked on this monitor, and that laptop was using a VGA cable w/DVI converter!
What is going wrong? I've been researching for hours but can't find a workaround anywhere for this particular issue (most questions involve a higher res monitor with lower res laptop, or connections other than HDMI).
I have the same problem. The computer does antialiasing on the external monitor, making everything burry, and I cannot get the antialiasing deactivated. – user3767013 – 2014-10-24T08:50:23.350
while your waiting for a proper answer, a search of this type http://superuser.com/search?q=underscan+overscan+hdmi might get you some info.

It sounds like it's a problem with your monitor, not what's driving it, if you're having problems via HDMI and VGA with two different laptops. – Nick2253 – 2014-10-24T15:30:46.167
With my old laptop, the VGA looked great (as great as my laptop's feeble vid card could make it, which was only 720p in anything that moved like videos or games). It was connected via a DVI converter. – DoctorWhom – 2014-10-24T15:33:43.063
So basically all you’re saying is that your wallpaper is positioned in an uncool manner? Please post a screenshot of your display settings, from the Control Panel applet where you set screen resolutions and positions. – Daniel B – 2014-10-24T15:41:47.893
Definitely not a wallpaper issue - it's that the Samsung monitor display is blurry. The wallpaper was an example that the only monitor display qualities that seem to be able to be altered are the background and size of objects. Nothing is changing the blurriness. I'll post screenshots. – DoctorWhom – 2014-10-24T16:37:34.483
