I bought a Vizio M43 4K tv a couple years ago that doubles as a monitor in my computer room, and it's great for CAD, gaming, etc., as well as a TV for cable and streaming video.It also displays large Excel spreadsheets very clearly, which is something the conference room projectors seem to have trouble with...(We're trying to convince TPTB that we need a 65" or larger 4K TV in my engineering office for     meetings, since we don't have enough conference rooms.) 
I did that a few years ago.  I was working as a design engineer for a machine shop.  In my office I had a pair of 27" monitors on my desk, but I picked up a TCL 37" smart TV and mounted it up higher on the wall.  I used it for when the guys came in with a question.  Rather than them leaning over my desk to see things on my screens, they could just stay back and I'd show it on the wall screen.

All the rest of the time it streamed netflix for me :D

A decent smart TV will net you a lot more screen space per dollar than a monitor, and you can get built in WIFI connectivity, Roku, Netflix, and a bunch of other apps for infotainment.  The screen mentioned above is now hanging in my garage and streams youtube or netflix while I'm working on the rambler, etc.

My 2 cents as to what the problem might be - the backlight. Doc, next time the monitor comes up 'blank', try shining a bright light on the screen and see if you can discern an image. It could be the cold-cathode fluorescent lamps (located along one or both top / bottom) or its inverter PCB have failed. Some, not all, LCD screens have the CCFL arranged such that they can be slid out for replacement.

-That's bigger than I'd want, and I don't really have proper room for it, the way my desk is laid out. 😁

I'm kinda leaning toward a pair of those 27s. The WACOM tablet is a high-resolution (not 4K) 27" monitor, and I like the size. Problem is, that'll likely be over $1,100 including shipping, probably closer to $1,250, and that's just too big a chunk of change right now. (I'm trying to save up for a CNC machine.)
Well, you don't necessarily need to get one that big - the smallest TV that does 1080p - probably a 32" -  would be a significant improvement, have a manageable footprint, and I'd wager cost dramatically less than a dedicated PC monitor even close to that size; I went through a lot of this consumer-math a couple of years ago, when I had the chance to buy a used-but-pristine 40" Samsung HDTV for $100. I then upgraded to the 42" LG 4K around August of last year when I donated the 40" for Gma to use in her long-term-care room, which then, far too soon, got moved out to my aunt's house to replace the old tube TV she had in her bedroom.

I'm sorry to hear that was necessary. I've been in that position too many times.

You have my sympathy.
If it ain't broke, I'll fix it!

I wasn't happy with the way many 4K TVs would display text and the lack of colour depth. My 4K LG TV is a great TV, but a terrible monitor.

On the quad core Xeon I used for video editing and CAD, I have a Philips 43" BDM4350UC 4K display which I really like. I did have to buy a video card to drive it and found a used Nvidia K4000 pretty cheap. That will drive no less than four 4K displays.

The Philips can take up to four different video feeds and tile them on the display.

when searching for video cards these days, good and cheap are not words you tend to use in the same sentence, unfortunately.

its likely the capacitors are starting to fail on the power supply.  If you are adventerous, you could take the back of the monitor off and look at the power supply for bulging or leaking capacitors.

Electrolytic Caps only have a approximately ten-year lifespan, depending on their composition and the operating conditions.

The LG TV I have has the IPS LED screen like that Philips - one of the reasons I got it.  I drive it with a GTX960, with no problems. I don't need PiP,  one 4K panel is all I really need. YMMV.  :)

if this is the pc i built see what port the monitor is on. if it on the mb video port make sure the bios is up to date on the mb. with intel ipgpu and gpu in a pc the bios sets which chipset turns on first. if it the gpu that first the monitor on the ipgpu may not getting a synk signal at post to turn on. in the bios make sure mulit monitor is on. if your using the mb video ports. also check that you have the newest intel ipgpu drivers installed. last thing check the monitor video cable for bent/broken pins/wires. if you dont want to toss the monitor if it going bad. you can look for the error online most people will tell you what caps needs to be replaced and may sell the repair kit on ebay or you can replace the failing board for a lot less then a new monitor.

If you get a huge monitor you can mount it to the ceiling and work from a recliner. Just don't be under it when an earthquake hits.
-There have been times I've thought of a recliner with an integrated PC. Problem there is I'd likely never get out of it. 😁 And I already spend four to six hours a day in front of this damn thing...
Power supply capacitors. Sounds like one (or most likely more) has finally boiled off to the point of no longer working; it's from that era of widespread capacitor rot. Search for the monitor's part # with "capacitor kit" and it should pop up some places that sell the proper set of caps for the power supply.
-I'm not sure it's a power supply problem, the monitor doesn't "shut off", it's just dark. I was thinking more along the lines of the bulbs (or whatever) that illuminate the screen. If it happens again in the morning, I'll try to remember the old flashlight trick- see if the image is there, just unable to be seen without the backlights.
As far as buying a monitor though, I gave up and just bought a 4K flatscreen TV. 42" LG.

Buying a new monitor might be the better part of valor in this case though. Lord knows the last thing any of us need is more projects that we don't actually care about.
-Yeah, that's pretty much what I had in mind. I wasn't really looking to try and fix it, it's basically spring out there and that means my workload is fixing to increase logarithmically. I bought this back when 24s were the biggest and bestest (apart from the fabulously expensive 30" Apple Cinema displays) and with a hot coupon, it still cost me nearly a thousand bucks.

But, it's also given me well over a decade of daily, each-day-EVERY-day use, with pretty much zero problems. No dead pixels- still!- no burn-in, no ghosting, no lag, etc. 'Course, I don't game on it and rarely even just watch a movie with it, so it's not like I'm really taxing the system, but still, if I have to set it aside, it's earned it's retirement.

Doc.
Weird not sure why it ate my link.
Anywho it's an Acer G246HL 24-Inch Screen LED-Lit Monitor
