Its a good price for what it is but must point out that the webpage has some inaccurate information. The refresh rate on the 4K model is 60Hz and not the 165Hz mentioned.

Have pc monitors incorporated hdr tech yet?

No. You can probably expect some to be announced at CES next month.

Eh, no but HDR is an umbrella covering a few different terms. 1) Must have good contrast ratio 2) must have good colour space coverage 3) must support 10-bit colour.

Well, a good monitor already has good contrast (1000:1), has at least 100% sRGB coverage and the good ones have 100% aRGB coverage (which is almost identical to DCI-P3 in HDR TVs, slightly stronger greens but slightly weaker reds) and support 10 bit colour. It effectively supports HDR.

A TV should do all of the above to give a good HDR experience but it's possible to cheat. You want the badge but none of the cost? Just support 10-bit colour as an input. It doesn't matter if you then send it to a 6 bit panel, one with a contrast ratio of 2:1 and with an sRGB coverage of 10%. This is why it's important to actually test TVs and compare them on proper metrics.

Don't hdr panels require a ridiculous brightness as well?

Acer Predators are overpriced because of the brand, but this is a good price for one, but IPS with a 4ms response time isnt amazing for gaming, but all 4k IPS panels will be about that.

Yes, from what I've read from the Quantum Dot monitor reviews is its too much for a monitor. It ends up putting the sRGB coverage well over 100% and ends up making thing look over saturated and overly bright - 99.9999% of the webs visuals are designed with a sRGB gamut in mind so I just don't think QD or HDR will work for general use on PC's.

A good monitor with high contrast ratios and 100% sRGB coverage is all you need, IMO.

It's overpriced because of G-Sync and not all IPS panels are 4ms, and 4ms is pretty much the absolute best for IPS.

Been this price on amazon for a while now, still a bit too much for me.

Eh, it's one way to solve the problem of good contrast ratios and bright colours of an extended gamut but not required.

Imagine a stained glass window that's stained green and blocks all other light. If we shine a red light at it, it'll all get blocked and the window won't let in light. Most monitors have a similar problem, an IPS panel can make brilliant colours but only if the colours are present in the original backlight. That's a problem for LED backlit panels since they tend to be blue LEDs with a phosphor coating to convert some of the blue to other colours. This results in weak reds and greens which is amusing because we need those to cover greater colour spaces.

The solution is to use LEDs of all different colours, though that's expensive since they need different voltages (or creative arrangements, either way). That's how you can buy a monitor from Dell that gives 350mcd/m^2 of light and covers sRGB, but if you pay extra you get one that's got a different backlight to give you 300mcd/m^2 of light but full aRGB, DCI-P3 and other colour space coverage.

This is where quantum dots come in btw, atm they're used to efficiently convert blue light to pure red and green so you can use cheap blue LEDs but still get the colours in your backlight needed to shine through the panel and give you proper colours in your image.

I'm not sure why really bright backlights would help, maybe if you've got an abundance of blue and weak reds, but then you keep ramping up the blue, your reds become acceptable while the blue's completely out of whack, but that's okay if you're making a cheap TV? Or maybe it's the contrast ratio argument, that if your whites are bright and your blacks are bright because of how bright the backlight is it somehow works out? Or maybe it's just the showroom setup, people gravitate to the brightest TVs that may not be the best quality.

this was 749 a couple of weeks ago with amazon price matching ebuyer. It seems to be the best 4k monitor out right now so if you need to buy one now, then this is probably the best option new

G-sync doesn't add a couple hundred, my minuotr is G-sync and it cost £60 more than the freesync model. Yeah thats what I was getting at with response time in terms of IPS gaming monitors.

How's this for specs -
34"
4K
Slim and curved
100mhz
Freesync
IPS Panel

for £569 Inc postage! crazy price, yes you're just as intrigued as I am, so what's the catch? Its not branded and not sold in UK so potentially warranty and after sales issues.

100 mega hz? my eyes cannot catch up

Excellent price but only 60hz so not for me

Yeah, can't wait for 4k 100hz (and not having to buy sli Titan xps to get anywhere near that).
Great monitor, and the 4ms thing - you really can't tell the difference between 1ms and 4ms.

The reason they are often cheap is because the panels MAY have some sort of defect, so could be dead pixels or bad light bleed. Don't trust what reviewers say since their units are very likely cherry picked, look at actual consumer reviews.
