PC 4K 43" monitors

I am in the market for a new 4K monitor.  My aging Acer Predator X34A has at 5 years old, delamination artifacts and I plugged an HMDI lead into the Display Port and now I have no display port input :(

I already use mini eWaste PCs for media centers on 4K TVs in the livingroom and bedroom.  Honestly, even sitting right up close a 4K desktop looks absolutely fine to me on the modern 4K TV.

I know a TV panel will not impress the avid gamer but I have modest requirements, as long as it does 60Hz at 4K and doesn't suffer from ghosting or smudging of text, it sounds grand to me.

A 43" 'proper' monitor panel will cost you £1000.  Yet a 43" TV panel sold as a monitor costs £450.  I'm thinking a TV sold as a TV might be even cheaper.

It seems the manufacturers are on to this as literally in the past few months more and more "TV panel 43"+" monitors have appears from Phillips and Samsung.  The give away is the almost complete lack of Display port inputs.  Which is a bit of big deal for me as my mini PC only does 4K on DP.

The only issue I have heard of and seen with a TV panel is "burn through", or persistence around areas of high contrast which can linger for a few minutes.  That said however, my £1100 Acer Predator X34 will do this as well if you leave it with black and white boxes long enough.

Any thoughts opinions?  Any deals spotted available to UK?  Best bets?  Is "Good used" on Amazon worth a punt to save £50?

IMO 43" is too big for a PC monitor which for best eye strain should be no further than 4 foot from your keyboard.  32" is about the maximum you want to go.

I have 2 x 28" monitors on a cantilevered arm - Samsung U28E590D.  When I got them they were £199 each, but it looks like the price has risen so you may want to wait for a deal.  More than bright enough, 3 inputs, 60Hz available on two of those including HDMI.  Only complaint is the auto detect input doesn't work that well so switching between work laptop and home desktop PC means fiddling with the control on the back - little joystick thingy.

More than bright enough even at 20% setting and I do occasionally play games on them - to my eyes no appreciably bad motion blur.

Note HDMI and DP are passive adapter capable, so my desktop PC has DP on it but is connected to the monitor using £8 DP to HDMI cables - works absolutely fine.    I believe the DisplayPort will switch into a HDMI backwards compatible mode so this should work with all HDMI monitors.  Be sure any HDMI port you use is 60Hz capable - 30Hz is dreadful for a PC monitor.

A panel delaminating after 5 years is really bad. Having worked with some TV makers in Asia, they all seem to target a level of reliability that would support them offering at least 6 years warranty and >8 year product life.

I use 43" LG TVs as my computer monitors. Gamers don't like them that much, but for the rest of us the panels are superior to the high end monitor ones, offering better image quality in exchange for a little less responsiveness. You have to hunt around the menus in most TVs to find the trick that puts them in 4:4:4 mode, with all the temporal filtering turned off, but I've yet to find a TV where you can't. The right settings are rarely documented properly, and some TVs love to keep changing those settings until you find the right trick to make them permanent. If you want a single monitor a TV is no problem. If you want multiple monitors you have a big restriction with graphics cards. TVs have no display port input, and few GPU cards have multiple HDMI ports. I use a GTX1050Ti with 3 HDMI ports, and three 4k TVs. I am very happy with the results I get. 40" TVs would be better. 43" is just getting a little too big, but 40" panels are rare these days.

DP has multiple streams, and spreads the bits across them at high resolution. HDMI does not. This was how DP gave us 4k 60fps before HDMI 2.0 increased the stream rates. HDMI<->DP is only a passive cable for lower resolutions. At high resolutions you need to carefully check what is going on, and the age of the equipment matters a lot.

wraper:
DP to HDMI passive adaptors are not really passive, they must include level shifter IC. Also they are limited to 4K@30Hz or 1440p@60Hz unless you do chroma subsampling.
