    Dell 27" 5K Monitor (5120x2880)

    Not as much of a problem since it has a real anti-reflective coating, not anti-glare. The OP video shows some reflection, but looks to be far less than usual even with direct sunlight on the background. They should have compared it to another glossy model without an AR coating.

    The great PPI/DPI debate:

    Agreed. I have 20/25 vision (as of last check), and I can read this 12 pt font in the browser from 6 feet away. Aliasing is even visible on objects on my 250PPI phone from ~3 feet away, and I sit about 18-20 inches from my desktop display. My vision has worsened somewhat over the past few years...

    The great PPI/DPI debate:

    OP: You may want to make the distinction between preferred PPI and preferred interface size. The OS PPI should always be set to that of the display if possible, as this allows documents (like images in Photoshop and pages in Word) to be shown at their real size. The size of interface elements...

    Dell P2314H "pixelated"?

    Does the new display seem to have cooler colors than your past monitors? You might try either calibration or just adjusting the display to be slightly warmer in case the intensity of blue is causing problems. Be sure that the display is not excessively bright as well. 6+2bit FRC will always...

    Dell P2314H "pixelated"?

    The shape of the sub-pixels can also play a part in the perceived sharpness. Usually both modern TN and IPS are good in this respect, but *VA panels can have shapes that depend on their brightness. It's possible the distance between the RGB filters and the AG coating would have an effect, but...

    Dell P2314H "pixelated"?

    If the screen looks like it is covered in very fine transparent sandpaper that sparkles slightly when shifting your position, that is likely the anti-glare coating. Did your prior monitors have AG coatings, or were they glossy? FRC usually results in what looks like faint random static noise...

    Dell P2314H "pixelated"?

    There is a cleartype tuner built into Win7/8 that should let you specify BGR or RGB pixels. If on an earlier OS, there is a PowerToy utility provided by Microsoft with similar adjustment functionality.

    Nasty hum from my Dell U3011

    Is the noise high-pitched? If so, and you don't mind voiding your warranty, you can use epoxy on the inductors to silence them.

    Is the flicker-free technology really good for our eyes?

    Actually, I was thinking of the fact that probably >99% of all photons you'll ever see come from sunlight (which obviously does not flicker). Yes, I should have specified rapid flickering. One of the largest factors in perceiving flicker is not the shape of the pulse waveforms, but their...

    Is the flicker-free technology really good for our eyes?

    The reason backlight flickering is used at all is one of manufacturing convenience. It is very simple to produce a dimmable light source by rapidly turning it on and off, though doing it well is another matter. Flicker-free technology is not new, it just means they took the time to design a...

    How to identify the type of pixel defect on an IPS panel

    Actually, IPS panels should block light by default when "off", and wikipedia seems to agree with this statement. However, it doesn't matter how a pixel is stuck dark or bright as all the additive color properties still work like they should. Your logic with the colored text appears fine, and...

    How to identify the type of pixel defect on an IPS panel

    Kind of a basic question, but are you sure the person describing the colors is not color-blind in some way? If not, perhaps some of the pixel wires might be incorrectly connected in an unusual way.

    Logitech G500s, anybody experience a high frequency squealing noise?

    The high-pitched squealing seems to be a recurring problem with Logitech mice. See more info here. Not sure about the G500 specifically, but many of the other models have the same problem. I had to get rid of a MX518 because the noise got louder over time, and eventually I couldn't stand to...

    Question about monitor (discoloration)

    Either a soft cloth or your finger. Only a small amount of pressure is necessary. It might have been damaged in shipping, or possibly during assembly. Any damage to the box it came in around that general area?

    Question about monitor (discoloration)

    Looks like damage to the panel from too much pressure being placed in that spot. You can try massaging it lightly, but I can't guarantee any improvement.
