Pros: As a long time devotee of "affordable" hi-res PC displays, somewhat ahead of the common curve, the Acer B326HK 4K/UHD (3840×2160) 32" monitor now strikes me as the perfect product for its time of introduction (Q4 2014.) Offering a reasonably priced, quality 4K, IPS, 60Hz capable display, representing a historically heretofore unmatched performance/price benchmark that, in my experience, has worked flawlessly, despite current PC hardware limitations (i.e., with existing, carefully selected DisplayPort v1.2a video cards and cables.) Note that neither dual-link DVI, nor HDMI 1.4 inputs can supply the bandwidth required by 4K at 60Hz; but that's not Acer's fault (though some current alternative 4K monitor designs work around the bandwidth problem by simultaneous use of two cables/inputs to drive the display.)
Subsequent to my "blind yet hopeful," uninformed Black Friday purchase from NewEgg, B326HK technical evaluations have appeared online; thus I have here offered merely a few subjective remarks to elaborate on minor but significant, often overlooked points. Properly set up, with careful attention to video card and cable selection, it is an excellent monitor, offering outstanding performance for its retail discount price. My sample exhibits relatively little light bleed (characteristic of all LCD displays, unless you're blind), good color uniformity, viewing angles, and no dead or stuck-on pixels. I also approximately verified Acer's impressively low power consumption claims for a 32" display; finding my sample to draw 58 watts at full brightness, and 50 watts after personal adjustment (in years past, 32" displays could draw well over 100 watts, and felt like working in front of a radiant heater.)
Cons: Really none to speak of; though of course one can wish for HDMI 2.0 and DisplayPort 1.3.
I'm not a gamer, but realize that they have extreme refresh rate and motion display requirements which, notwithstanding G-sync, impose bandwidth requirements that currently make 4K res video a dubious proposition with virtually any present-generation monitor and video-card/cable. Happily for the rest of us, a relatively "affordable" high quality (IPS) 4K monitor is a godsend, too long in coming; and with the Acer B326HK in stock, there is no need for further delay. Of course 2015 will likely see competitive price cutting; as well as commercial introduction of even higher bandwidth HDMI 2.0, DisplayPort 1.3, and 5K (5120×2880) res screens, each a worthwhile advance-- but IMHO, 4K at the performance/price level achieved in the B326HK is simply too useful today to hang back 'till spring, summer or next fall. And I say this as someone who, in retrospect, overspent last year on 27" WQHD (2560×1440) screens.
Other Thoughts: Individuals vary wrt both visual acuity and focus (i.e., preferred working distance.) My vision is neither outstanding nor much below normal. For extended viewing while working on a desktop PC (vs a phone or tablet), my preference is for a working distance of circa 2.5 to 3 feet. What I find is that, displaying a static, b/w (i.e., high contrast), single-pixel-checkerboard full-screen on the B326HK (such as with the FlatpanelsDK utility)-- I can just barely distinguish the granularity of individual pixels at a viewing distance of 3 feet, while at greater distance, even extreme contrast pixels blend, and the screen appears as if a smooth/uniform, 50% gray. Thus, I conclude that for my use at a viewing distance of 3 feet, the 32" screen size is an ideal match for 3840×2160 pixel display; i.e., without superfluous "wasted" pixel density, nor on the other hand, does the image suffer from noticeable pixelation. Your visual acuity and habits may differ.
Some criticize Acer's excellent, well engineered base for offering limited movement (i.e., with height and tilt adjustment, but lacking left/right in-base swivel and/or pivot to portrait orientation.) However, they fail to consider: 1) the unavoidable design trade-off of providing safe/stable support for a 32", 20lb screen, while limiting desktop footprint; and 2) money poured into a monitor's base is of no value whatsoever to the many purchasers who wish to supply their own mechanism for support. E.g., I use the excellent Newegg/Rosewill RHMS-13001, advertised for 27" max screens, yet well suited to the larger B326HK, still within the arm's 30lb max design load spec.
But the possible substitute base issue entails a further concern. Acer's B326HK base employs the monitor body's four 100x100 spaced VESA m4 threaded screw holes, instead of an excellent (though sometimes criticized) independent hook/flange engagement used on smaller Acer models. The attachment plate's screw holes are effectively countersunk, with the screws themselves consequently fairly short, circa m4x10. Of course it is crucial that overlong screws, which might bottom in the body's wells NOT be employed. However, with a thicker substitute mounting plate, in one hole the original screw would not tighten, and at first I thought that the hole threads had stripped-- but that was not the case. The problem was a slightly deeper offset, such that, combined with my thicker substitute plate, the original m4x10 screw was not engaging. This prompted me to examine the 3 other VESA attachment screws; with belated realization that although they had engaged adequately to "tighten", that was not by much. I solved the problem with m4x16 screws plus lock washers (after checking with the plate, not to bottom.) Although m4 screws seem thin and finely threaded to carry a 20lb load, there are four of them; and with commonplace monitor orientation (i.e., tilted slightly back) the load generates only a shear force.

This review is from: Minisuit Keyboard Stand Case for Google Nexus 7 FHD 2nd Gen (2013)
Pros: I find this relatively inexpensive keyboard/case to greatly enhance utility of the Nexus 7 FHD (2013) tablet. Providing both a thin, lightweight physical keyboard (coupled by Bluetooth) and a protective leatherette case for both tablet and keyboard.
Cons: Of course, lacking a wired connection (for which the tablet has no provision) it is necessary to charge the keyboard separately. I have not yet run-down tested KB battery life, but it seems to be at least comparable to the tablet (providing circa 6-8 hrs use.) However, one uncertainty/worry I have is: how long will the battery retain a useful charge if/when you forget to turn the keyboard off after use? I haven't as yet checked.
Other Thoughts: Very nicely designed and put together.READ FULL REVIEW
This review is from: 2014 New USB Voltage Current Tester Meter Charger Detector Power Bank Cell Phone
Pros: Small/portable (the size of old thumb drives) and to my thus far limited testing both generally accurate and highly consistent/reproducible (i.e., readings from my two units track within 1% )
Cons: One of my units is slightly fussy wrt insertion, and delivery to NYC did take the specified 15 days-- but I should have ordered three, months ago.
Other Thoughts: An essential, informative tool for any housewife or other USB port appliance or device-charging consumer. Voltage and current are displayed alternately for a couple seconds during each circa 5-second cycle.READ FULL REVIEW
