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.
- 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.
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).
