from the moar-pixels! dept.

[Update: WOW! Thanks for all the useful feedback! Plenty of information on the TV-as-a-monitor side of things (but feel free to add more!) Would very much appreciate it if folks could provide some input as to what has worked for them in using a laptop to drive a 4K display. I'd consider a used system. Would, ideally, like something that costs in the ~$300 range, but am resigned to the fact I may have to kick out more like ~$750. What graphics adapter do you have. Is it an integrated model (e.g. Intel HD 630) or discrete card? What model? What troubles, if any, have you had with getting proper drivers (windows OR Linux/Debian/BSD/etc.) Could you get the full 60 fps or were you limited to 30 fps? See below the fold for details on my current system and what my needs are compute-wise. --Bytram]

Summary: I need more screen space.

Which means I'll need a new (to me) laptop (portability++) which can support more pixels. I want a system that is Linux/BSD friendly. I don't have a whole lot of money to spend, so I'm hoping I can draw on the experience of my fellow Soylentils to help point me in the right direction. I'd like to avoid overspending, but I don't want to find that I've boxed myself into a corner for making an ignorant mistake.

I used to follow the bleeding edge of technology, but I've now firmly moved into the "I want it to just work" camp.

Current Display: I have a 24-inch, 1920x1200 computer monitor. The majority of my display is taken up my Internet Browser (Pale Moon) which generally has 50+ tabs. It is flush with the top of my screen and covers the entire display except for a ~2 inch margin on the sides and 3 inches on the bottom. That overlays my HexChat IRC (Internet Relay Chat) which runs across the bottom 1/3 of my screen. The remainder of the screen has corners of command windows poking out as well as various utilities like an analog clock, performance monitor, connection monitor, etc.

TV as Monitor: Over the past few months I've seen the prices for 4K (3840x2160) televisions plummet. I've got my eye on a TCL 43S517 43-Inch 4K Ultra HD Roku Smart LED TV (2018 Model) which Amazon has on sale for $349.00 with free shipping.

As I see it, I could get a display with better dot pitch than what I have now, and much more screen real estate, for relatively little money.

The vast majority of what I do is command line based, be it in a Windows (7 Pro X64) CMD.exe command window, or an occasional PuTTY session into Soylent's Servers. I do not do any video gaming. My only video needs are an occasional short clip from YouTube, or a DVD (I have neither cable TV nor do I stream video with Netflix or their ilk; no Blu-ray, either). Internet access is currently via a tethered LTE cell phone.

Current computer: Thanks to the generosity of a fellow Soylentil, my current system is a Dell Latitude E6400 with a Core 2 Duo P8700 (1.8-2.5 GHz) with 8GB RAM and a 500GB 7200-rpm WD Black disk drive. Video is handled by a NVIDIA Quadro NVS 160M.

New Laptop: My current is not going to cut it. So, I'm also on the lookout for a new (to me) laptop. I don't need much in the way of compute power. I figure pretty much any i3 or i5 should be more than enough for my computing needs. And, an Intel integrated graphics chip should be up to the task given a recent enough generation, but I'm not sure how current a model I'd need. I'm further confused by the different connection schemes and versions. I've found this page on Intel. What will I need? HDMI 1.4? Display Port 1.2? Other? Would I be able to run both a 4K monitor @ 60Hz and my existing 1920x1200 display?

With the increasing trade war rhetoric, I'm getting nervous there may be a price spike in the not too distant future. Further, I sense merchants are clearing out the current stock in anticipation of the holiday season, so I'm thinking the time is right for me to take the plunge and upgrade.

Conclusion: So, what have your experiences been using a 4K television as a computer monitor? What 'gotchas' have you run into? What things did you learn the hard way that you wish someone had told you about beforehand? What driver problems have you encountered? Did you have any issues with Linux/BSD drivers? What worked for you?

    Make sure your HDMI cable doesn't support ethernet-over-hdmi either.

    How am I supposed to make sure my HDMI cable doesn't support ethernet (aka: HEC) when it has been part of the standard since v1.4? Even the super cheap AmazonBasics cables support it. So everyone who thought they were protected because they didn't let their smart TV connect the WiFi but still connected their computer/xbox/playstation/etc with an HDMI cable made after ~2010 were unknowingly providing the TV with a wired network connection. DOH!

    If you want to avoid ethernet over HDMI, the only option is to verify the TV itself doesn't support HEC. It costs extra to build in support and some manufacturers opted to lower BOM costs rather than provide it. However that may have changed...

      Excellent point. I would like to think that there would be a way on my computer to enable/disable that ethernet connection over the HDMI cable? Just guessing here, but it seems like an obvious thing to be able to do. Can anyone confirm one way or the other?
