Acer X27 4k 144hz HDR Gsync

It wouldn't, but you cannot run this monitor at 2560x1440 and 144 Hz. It only supports 60 Hz at non-native resolutions.

Wait, what? Is this for real? Only 4K resolution will work over 60Hz? Can't fall back to 2560x1440?? What about driver scaling 2560x1440 to 4K?

Might be possible. You can run DSR resolutions up to 8K at 120/144 Hz, so I don't see why it wouldn't work going the other way. I'll have to test it out.

I don't think it's any different from any other monitor. It was the same with my VQ278HE and PG278Q. Manufacturers probably don't think it's worth the time to test and nail down the timings for non-native resolutions.

Changing the resolution from Nvidia control panel works fine on the PG278Q but it uses GPU for scaling since the display doesn't have its own scaler. Changing resolution from Windows settings drops refresh rate to 60 Hz but you can fix it from advanced settings or by using NVCP to change it instead. No matter if you use 4K upscaling or drop down to say 1080p the OSD still reports the resolution as 2560x1440 @ 144 Hz. My guess is that the situation is the same for the new 4K displays.
 
Turn on HDR + max brightness for SDR content = holy shit that's bright

Oh, so you just have to manually set the refresh rate to 144? That's no big deal really. People freaking out about nothing.

If it's really a problem, all you need to do is delete the 60hz resolutions with CRU.

It's just some Windows 10 quirk since changing the resolution from games or NVCP works fine.
 
Currently $200 off on Newegg - I pulled the trigger. Perfectly fine with the 120hz lmitataion, it's not like you're going to get much higher then 120fps @ 4k in newer titles with the settings cranked.
 
Today I received the new mounting bracket for the display with venting holes. Been running the display for an hour now and don't hear the fan at all. I have checked if the fan is spinning and it is but at a much lower RPM. I recommend opening a chat with ACER support if you ordered the display early on and have the old mounting bracket and asking for the new one, there was no charge and it arrived within 3 days.

Edit:
Pretty confident there will be no noise under most situations. Just played 20-25 minutes of an HDR game at 144hz to test worst case scenario on the FPGA/G-sync module had no sound coming out of the display either. Maybe if ambient temps were higher you could possibly get it to crank up, but right now my room temp is 74F / 23C and the fan has been inaudible since I turned on the display 1hr 30mins ago.

I don't have any issue with the fan in my X27. Yeah I just use 120 Hz, anything is better than 60 or non-VVR.
 
My X27 came in from Amazon the 3rd. Everything was fine until I noticed a few rows of dead pixels on the upper right corner of the screen. Other than that it seemed like it would've been a perfect monitor. Fan was whisper quiet and no noticeable light bleed or IPS glow. It was a June build and came with the updated vented VESA mounting bracket. Glad I ordered from Amazon, should have a replacement by Monday.
 
I have 3 dead pixels on the far left (ie 9 subpixels) this exceeds Acer's the limit of 5 subpixels off 1 on. But I've been through this before years ago with another $2K screen, everything else is working flawlessly, it's not worth the hassle of rolling the dice again and maybe getting a stuck-on subpixel. Not unless any of the defective pixels are in the center of the screen, that goes right back for exchange.
 
Seems like Acer is getting the second rate panels and Asus gets the top pick. I'll definitely be skipping this and getting the PG27UQ instead.

I just received mine from Newegg and have no dead/stuck pixels. The stand is higher quality on the acer as well.

I don't think the panel is the issue. Acer is the parent company of AU Optronics, so you would think Acer would get top pick. I think the assembly by Acer is what kills them compared to ASUS. Slight mishandling of the electronics or indeed the frame could cause issues. Every monitor from Acer that I've demoed have seemed very cheap compared to the ASUS version using the same panel.

This monitor's a piece of fucking crap. At its price, it's a flat out insult to consumers. It's basically just drawing a line in the sand and saying that "we think gamers are idiots who will spend a lot of money on shoddy products."

4k, HDR1000, and 10bit/98hz / 8bit/120hz + G-Sync.

It hits all of my expectations.

For the record any resolution I set windows at the display scales just fine @ 120hz. I'm not sure if it's the display itself scaling or the nvidia drivers but it looks fine. Just tried 144hz as well and it works. Not that i'd ever use this panel w/o native resolution, but this complaint makes no sense.

Jesus all you do is crap over every thread about products you can't afford. Get over it! This is one hell of a monitor.
 
I mean, it would be a valid complaint if this wasn't bleeding edge technology - But at the end of the day you've got to pay to play, and for me personally I've been waiting for high refresh rate HDR for quite a while now. It's worth the cost for me knowing this panel will last me quite a while until the next big display technology comes out.

Pretty much all monitors do a garbage job of scaling anyway. The correct way to deal with this is scale on the GPU and push the full native resolution to the panel, too bad Nvidia still doesn't support nearest neighbour scaling in Windows drivers. At least some game engines have scaling built in.

AHAHAHAH can't afford. Give me a break dude. Stop slinging around personal insults especially when you have no idea what you're talking about.
 
OK, I went up to the capitol over the weekend and had a look at PG27UQ.

I noticed that it had very weird resolution choices. Like 1920x1080, 1920x1200, 1920x1440 were available but there was nothing between 1920x1440 and 3840x2160, not even 1440p.

Is X27 the same?

Still stuck on my monitor choice. the LG VA 1440p G-Sync is now discounted to about $250 more than XB271HU, perfect size and VA but no ULMB is a huge kicker. Also X27/PG27UQ doesn't have ULMB either?

They are exactly the same - The X27 has a better stand, the Asus has more light gimmick stuff.

No ULMB, although that's not a thing I personally care about.

These are the resolution choices that I see available - Capture.JPG

At the end of the day I think it's worth it if HDR is something you want. If you don't care about HDR then cheaper options are the obvious choice, but honestly HDR to me is a game changing technology that makes it worth it.
 
Strange, granted, the monitor the PG27UQ was hooked up to was a GTX 1060, but that shouldn't have limited its resolutions. The available resolutions were the same as you listed, except both of the 2560 wide ones weren't available on the display monitor I saw as options, which I thought was VERY strange.

Are you able to use higher than 60hz for 2560x1440?

Yes - If I select 2560*1440 I can either run it w/ the monitor @ 144hz and 4:2:2 or 120hz RGB. 120hz RGB it scales quite well and is honestly tough to even notice you aren't running native resolution. 4:2:2 is garbage for text, but in a game it wouldn't matter much if that extra 24hz means that much to you.

Neither have your pointless rants.

The X27 is incredible. You wan't bigger, go buy the 43" i20 Mango 4k120. It was on sale @ $939 for over a month, why didn't you buy it? Its right up your alley, big, cheap, 4k120. So go buy one of those, and leave this thread never to return.

Yeah it's really annoying that both AMD and Nvidia still don't have better scaling solutions on PCs. Better scaling has been requested for years and neither company seems to want to do it for some reason so any non-native resolution is a blurry mess. I remember years ago I compared the scaling between my Dell 3008WFP and Nvidia GPU and the Dell looked a lot sharper at any lower resolution. Afaik this hasn't changed so not only is Nvidia's scaling garbage quality but it also doesn't support 1:1 scaling for resolutions where it would be possible.

Just bought the little brother, the XB271HK.
Paid it one fourth of the x27 and it rocks.

No way that this monitor worth that mkney

All thsoe Mango TVs are crap. Aren't they pushing triple digit input latency?

I know, pretty hilarious. It's almost overkill for his monitor considering he's limited to 60hz.

I complain over the rtx even but I sold my 980ti sli bbefore the rtx presentation thinking on a good product. Shame on Nvidia too.
