4K Monitor?
-- Giga Nano
I'm thinking of stepping up to a 4K monitor and I would appreciate any insight or experience. I'm currently running Windows 10 with two Dell 24" 1920 by1200 monitors off a Nvidia 660. I'm looking for all around use -- I mostly do productivity stuff, PowerPoint, some video editing, general web browsing, Netflix, a little web development… some gaming.
  • First question:  27"or 32"-- is it worth the price bump to move to the bigger size?  Are there problems with Windows 10 scaling on the 27"size? 
  • Second question:  HDR is seemingly the next big thing.  How important is that on a computer display?  
  • Final question, is there anything else I should be looking for?
 
Padre's Favorite 27" Monitors
 
* 2560 x 1440 (60Hz) w. Anti-Glare coating
* IPS (178 degrees x 178 degrees viewing angle)
* HDMI (MHL), DisplayPort, Mini DisplayPort
* USB 3.0 Hub
* 6-8ms Response (Grey to Grey)
* 0.2331 Pixel Pitch
 
* 2560 x 1440 (144Hz) Anti-Glare Coating
* NVIDIA G-Sync
* IPS (178 x 178 degree viewing angle)
* HDMI 2.0, DisplayPort
* USB 3.0
* 2x Speakers
* 4ms Response Time
* .233 Pixel Pitch
 
* Padre would skip the 32" and 34" monitors because some of the best ones are the ultra-wide
*Great for Video editing... Not so much for movies, gaming, etc.
 
* 3840 x 2160 (60Hz via DP)
* IPS (178 x 178 degree viewing angle)
* DP 1.2, mDP 1.2, HMDI 1.4 x 2, VGA,
* USB 3.0 (4-port hub)
* Can be used by 4 seperate computers (1080p)
* 8ms Response
* 0.2451 Pixel Pitch
 
HDR
* It's not yet Ready
* At CES 2017, all the bigs (Dell, Samsung, LG, Acer, Asus) all announced HDR gaming monitors and they're STARTING to come out... however...
1. They're CRAZY expensive
2. HDR standards are in flux... and confusing.
 
Monitors for my Chromebox
-- CaffineFreeDave
How do I choose a monitor for my Chromebox i3 4GB? I don't want to get one that I can't drive or don't get the most chrome out of my box. I've never bought a monitor. I've always bought a laptop and the monitor is always included.
 
For a system using Integrated Intel HD Graphics, the max resolution is determined by the generation of processor
* If it's a 3rd (assuming HDMI connectivity) then you're limited to  2560x1600
* If it's a 4th - 7th gen, then it will support up to 4096 x 2160
 
HOWEVER... an i3 is going to struggle at 4k.
* I'd suggest a 1080p monitor... MAYBE a 2k monitor if you're not going to do a lot of graphics-intensive work
 
Here's a good resource for Maximum Resolutions
 
SSD ME!
-- GeekWise
What would you recommend for a 500GB SSD for my home desktop? It will be my boot drive that I really need to replace. It's a Dell Studio XPS 435MT with an i7 CPU and 24GB of RAM. I need to stay under $200.
 
* Requires M.2 PCIe 3.0 x 4
* 1400MB/s Read -- 1000MB/s Write
 
* 800GB
* PCIE 3.0 x 8
* 6800MBps Read -- 5000MBps Write
* 1,000,000 IOPS
 
** But both of those are WAY beyond his budget
** Also, they won't work at their full capacity because the XPS 435MT doesn't support PCIe 3.0
 
  - 1x 2.0 is limited to 500MB/s per lane (1.0 is limited to 250MB/s)
  - It's actually LESS once you consider the overhead
 
In fact... the XPS 435MT is limited to SATA version 2.0... that limits transfers to 3Gbps
-- Taking away overhead, that's about 350MBps
-- Anything faster is not used.
 
* 500MB/s Read --- 450MB/s Write
* This is a grab-bag of memory.
* Reliable... but not the tighest tolerance part
* Only get this is price is REALLY an issue
** It's still more than fast enough to saturate the SATA 2.0 bus
 
* 550MB/s Read -- 500MB/s Write
* MUCH more reliable... this is what I would get.
 
* 540MB/s Read -- 520MB/s Write
 
* This comes with the upgrade kit... you can try to get OEM and knock up to $20 off the price
* 560MB/s Read -- 530MB/s Write
 
Bug Out Baggage
-- J. Riccardo
I just watched New Screen Savers episode 122 where Padre and Patrick Norton talked about their bug-out bags. Interesting idea, but both of them only had water for a few days at most. I think any real Bug Out Bag needs to give the user the ability to stay off the grid for weeks or months at a time if the excrement strikes the air-moving component of the  atmospheric regulator. Will you be doing a Know How version of the Bug Out Bag that includes a longer-term water supply?
 
 
 
Rud Dog
-- 3.3volts
Suggestions for a small 12VDC in 3.3V out for current project? Looking at this one but can't help thinking wasted power in the form of heat?
 
* 5v to 23v -- step down to 1v to 17v (but can only step DOWN, not up)
* Adjustable with the on-board potentiometer
* 3Amp Max (I only trust it to 1Amp)
* No heat problem. It doesn't "dump" power... it switches on and off using "synchronus rectification"
  - Instead of diodes, uses transistors to do the switching
  - Reduces voltage, but increases current
* MUCH more efficient than a linear regulator (they dissapate extra power as heat)
 
** Padre has a hack for this little voltage regulator!
