okay, so it's kind of like the old days when we have passive matrix vs. active matrix. Among all the other owner of this monitor, I wonder if anyone else have this problem?

It's a VA panel and VA panels even today have their share of viewing angle issues, even though they are much less noticeable.

One issue is vertical color shift. Which you can in practice only encounter when e.g working on photos or vector graphics that have a very large single color object that spans the entire screen. Then there can be a shade discrepancy between the top and bottom. In any other use this is IMO invisible. I work with photos sometimes and it hasn't really bothered me at all, like it would not be anything that would make this difficult to use for photo editing.

The other is viewing angles in general where it loses contrast if you stand up or are very much to the side of the display. When sitting in front of the display, it's not a problem.
 
It's not the kind of display that's designed for having people sit around and watch it. That's a job better suited for a TV. In my opinion curved displays of any type aren't really good for that. But that said, it's more forgiving than it sounds like. If you aren't centered on the display its still not bad but once you are physically at the edges of it (not sitting in the center and looking at the edges, but physically located beyond the edges and looking at it), the viewing angles aren't great. I've seen many monitors that are far worse in this regard though.

I'll put it this way, for productivity this thing is unmatched. For gaming, its not the best monitor you could have. It's not the best for watching movies. It's got some drawbacks like local dimming really being needed for gaming or watching movies but being kind of a shit show for productivity. All of that said, the monitor is fantastic, and I think its good at everything, but only great in a couple of areas. For me, where the monitor excels, it really is unbeatable. But like every other monitor on the planet, its a compromised solution. So it isn't for everyone.

Amen. I love it as a productivity display, and it's a good compromise between desktop space vs comfortable scaling vs sharp text/UI.

I don't even use mine for gaming atm at all, I moved my PC into my living room and play games from the couch using my LG CX 48" OLED TV. It's just a more straightforward solution.

so thank you for the above people on your input. I just measure my space, I'm using a 43" UHD monitor, currently and I know the actual width of the Samsung 57" is 52.5" wide. And in front of my monitor is a 60" TV, so I am going to see if I can view the monitor off center by 6" to my right, instead of viewing the monitor dead center. I hope it works out

P.S. to get 240Hz, are you bunch of 57" Samsung owner all using the cable that c/w the monitor? assuming you are using the Display Port 2.1 cable? as some review said that cable is only 3 ft

You can get VESA certified DP2.1 cables up to 5 meters now. I am using a Silkland 2 meter cable which works absolutely fine at 7K@240hz.
 
okay, I know that's a generic brand from Amazon that is from 1 of those made in china generic brand co. But regardless, shouldn't it be 8K @ 240Hz? what good is 7K ?

1 other thing, what do most Samsung 57" user buy? HDMI 2.1 or DP 2.1 cable? because that little 3 ft. DP 2.1 cable is too short for most of us

so does most Samsung 57" user moves to HDMI 2.1 or buy another DP 2.1? I'm leaning on Display Port but I'm open to survey results. If most of you bought a HDMI 2.1 cable, I'll do the same
 
I just use the stock DP 2.1 cable because it's plenty to reach my Macbook Pro sitting closed in a vertical stand right behind the monitor. I then use a HDMI cable to run the display in Picture by Picture mode because MacOS can't scale this thing properly with a single input.

For PC it depends entirely on what GPU you have. I just use HDMI 2.1 because I have a 4090 which still can't do 8Kx2K @ 240 Hz over HDMI even though in theory it should. Nvidia seems to have just cheaped out on things for anything but the 50 series.

With AMD 7000/9000 and Nvidia 50 series it should not matter if you use DP or HDMI. DP will likely work a bit better because it seems to wake up from sleep slightly faster.
 
I use the included DP 2.1 cable. It's long-enough to reach my PC.

I run it at 240Hz. My video card is 5090. There is a problem with power saving. When Windows turns off the monitor, the OS freezes (or at least that's what I think is going on). I just disable turning off the monitor. Not great because this monitor runs somewhat hot.
 
There are fiber hdmi 2.1 , dp 2.1, and usb-c cables available. They are pricier, with the longer ones especially expensive for long runs. They don't all perform as advertised so you'd have to do your homework. . but they do exist. I have a few fiber hdmi 2.1 cables of different lengths that work great, but those have only been used on my 4k 120hz screens so far. There seem to be few dp 2.1 fiber cables advertising 80Gbps so far though.

I have a fiber hdmi 2.1 cable that is 35' long that I used without any problem for 4k 120hz HDR gaming for awhile at one point. They make much longer runs than that, but the longer cables get expensive.
. . .

Google results on some fiber ones but if you look around you could probably find others. Sometimes they get bought up and go out of stock though, which is another problem.

80Gbps (DP80) DisplayPort 2.1 cables exist, including active fiber optic options that allow for longer distances than traditional copper. These cables support full UHBR20 bandwidth (80Gbps) for high-resolution setups like 16K at 60Hz or 4K at 240Hz, featuring VESA certification for reliability.

Key Considerations for 80Gbps DP 2.1 Cables:

Fiber Optic Options: Active fiber optic DisplayPort 2.1 cables exist, such as models from FIBBR and specialized listings on Newegg.
VESA Certified DP80: Look for "DP80" or "VESA Certified" to guarantee 80Gbps, such as those from Cable Matters or Silkland.
Length Limitation: Traditional passive copper DP80 cables are limited to shorter lengths (around 1-1.5 meters). Active fiber or specialized "low loss" (DP80LL) cables are required for longer distances.
Compatibility: These cables are fully backward compatible with DP 2.0, 1.4, and 1.2.

Ensure you select a cable that explicitly states it is VESA certified for DP80/UHBR20 to achieve the full bandwidth.

For a 7680x2160 (Dual 4K) resolution at 240Hz with HDR, you need a DisplayPort 2.1 cable certified for DP80 (80Gbps) to handle the massive bandwidth requirements. While standard copper cables are limited to 1–2 meters for this speed, Fiber Optic (Active Optical) cables allow for longer runs while maintaining the necessary signal integrity.

Is the OS frozen on the display and the OS inaccessible (e.g. inaccessible from another device on the lan, or anything left running with sound still running or not if only the screen was set to sleep?) - or is the screen just staying "off"/blank, or does the display say "no signal" ?

If, when that happens, unplugging and plugging the display cable back in, or uplugging/cutting power supply to the display and back on works, (or connecting another monitor to one of the other ports even) - then you may just have to re-initialize your gpu with the shortcut "Ctrl+Shift+Win+B" . I have that mapped to a button on my stream deck because sometimes one of the three screens in my array will have "no signal" when I turn the three of them back on. Happens once in awhile.

Certified or not, some of the fiber ones reportedly work but that is just reports, I haven't tested any other than a hdmi 2.1 fiber cable that was 35' long to a 4k 120hz HDR display. Even if a few fiber dp 2.1 work, there are others whose claims do not hold up though, so you have to read through reviews and buy from a place with a good return policy. Any from Egg look like they are only from 3rd party sellers and I wouldn't want to deal with that through egg, or egg in general if I could help it.

If that one was in stock at amazon and I had the need, personally I'd try it out, test it for a week and just return it if it didn't work out. I suspect that more will show up someday, same thing happened with fiber hdmi 2.1 cables.

Alternately, this is a 6.6 foot copper one that reportedly works well:

I think Silkland is also a brand certified by Displayport.org as well. 8K at 240Hz will do the job for anyone of us.

Even if that mouse supports 8k, you can and should run it at 1k. It's just a software setting.

Some models can be opened and the battery replaced yes, but battery life in so good at 1000hz nowadays you won't have to worry about it for many years anyway.

I haven't spent the time trying to narrow down what's going on. I think Windows just hangs badly because even pressing the power button doesn't make Windows go into its shutdown operation as it normally would when the system isn't hung.
 
have you try using a different cable? I have similar problem w/ my new VX4380 4K monitor 6 yr. ago. Turns out it's the cable. Also, how long do you own the Samsung?
 
So even on the newest 1009.2 firmware, I have to press the power button on the monitor to turn it on from being off with PC bootup. RTX 5090. Anyone else run into this problem? I don't see any monitor deep sleep type selections in the menu.

You guys without the issue, are you running in DP 2.1 mode in the settings?
 
I am 99% certain that in this thread, someone has the same problem: that they put the Windows 11 on sleep mode after say 15 to 20 min., and the PC won't wake up as the person come back after 20 min., and move the mouse. I read it in the previous pages months ago

I didn't know TCL has the same monitor but at 120Hz.
Click to expand...
It's basically the "everything about this is worse than the Samsung" version. There's afaik a thread about it here somewhere. You can't even find a manual for it online!

The only plus I can think of is that it has a USB-C input with power delivery, though it's not clear whether it works at the same time as the DP port or if it works with the KVM feature.

I wish Samsung had left out the HDMI 1 port and put in USB-C in its place. That would be more useful than an extra HDMI that has worse performance than the others.
 
I thought there is a USB-C port at the Samsung model?

but this TCL version is still made by Samsung, isn't it? it must be a OEM samsung, TCL didn't make this
 
I've had non stop issues with this monitor running DP 2.1 since like Q3 of 2025 after some Nvidia driver update (5090). It wouldn't wake from sleep, it would turn into grey static with purple vertical slices when launching some games with RTX HDR, etc. I was ready to throw it out a window.

All of these seemed to be related to display port because I thought it was necessary to achieve 240hz at native res but I swapped to HDMI and found it's also capable of 240hz at native with a 5090. Since moving to HDMI all those issues went away.

About the TCL version, if it was 240hz I'd buy it in a heartbeat to replace this. The local dimming in low APL is so cloudy, slow and poor and is a total eye sore. That and how badly it crushes dark detail makes the overall HDR experience really flawed. Having used the TCL 32R84, I much prefer it's FALD algorithm which the 57 likely shares.

Mini led options just suck right now. I'd be willing to go back to 16:9 for the right monitor. All of the recent OLED offerings have left me unimpressed including the 39GX950B which was going ABL crazy dimming the screen during effects in Diablo 4.

TCL makes the panels for Samsung, they make TVs so I expect they can also manufacture monitors.

No USB-C on the Samsung. It's 1x DP 2.1, 2x full speed HDMI 2.1, 1x HDMI 2.1 with lower capabilities. I think the idea with the last HDMI port is to be used with games consoles, or the controller just didn't support 3 full speed ports. 2x DP + 2x HDMI or 1x DP, 1x USB-C + 2x HDMI would've been better.

There is a 2x USB-A USB hub with 2x USB-B ports you connect to your computers. You can assign the USB-B ports per input so if you change input it will automatically route to the right computer. Or you can press one of the buttons under the display to switch when in PbP mode. It's a neat way to have a KVM that is good enough for occasional computer switching, but not really suited for simultaneously operating two computers.

I currently have it connected to my two Macbook Pros (M2 Max and M5 Pro) for personal vs work use. I have a USB hub on the USB ports to expand the devices that can be connected.
 
For the 57" screen's dimensions vs. it's curvature, it has limitations. You can't realistically, or optimally, sit at it's center of curvature since it's 1000R , 1000mm, 39 inches. If you did, the screen height would then look a lot shorter and belt like to your perspective so it's not really viable.

this a pic from pete matheson's channel on youtube, showing the distance he chose to sit from the 57" 32:9 screen. (Dotted line added by me). It looks suitable for this screen considering it's parameters/limits, but it's well inside of the center of curvature.

For those who said you have to sit min. 2 ft. from your 57", this guy is sitting about 2 ft.
Click to expand...


🤣 Sure you could do what the guy in that picture is doing, , but the PPD will be horrible.... (to your perspective, the pixels will look effectively much larger the nearer you sit and the larger the screen is).

gZC7Z25.jpg



A 48" 4k viewed at 36" away
https://phrogz.net/tmp/ScreenDensit...sizeUnit:in,axis:diag,distance:36,distUnit:in


Say the screen the guy in that previous reply's link is 12' diagonal, 144". I'd say it actually looks like he's sitting at least 3' away, because if he outstretched his arm, it wouldn't reach the screen.

https://phrogz.net/tmp/ScreenDensit...sizeUnit:in,axis:diag,distance:36,distUnit:in

3' away from 144" diagonal screen is around ~ 32 PPD.

For comparison, a

32-inch screen viewed from 3 feet away getting 32 PPD would be around 1280 × 720 (720p HD), (exact custom calculation is 1420 × 799 at a 16:9 aspect ratio).

32" screen at 2' ' away from you at 1080p gives you around 29 PPD




A 4k screen gets 64 to 77 PPD when viewed within the human central viewing angle of 60deg to 50 degrees width. Beyond that it gets progressively worse, and the off-axis viewing angle outside of that grows larger and more off-axis. To me, 60 PPD is the bare minimum now, and I prefer my main scene (and HUDs) within around 60 degrees or so at worst (64 deg on a 4k screen = 60 PPD).





-------------------------------------------------------------

... The pixels outside of your central view will also be progressively more off-axis (pointing away from you more and more the farther away from you they are) - which causes distortion and exacerbates uniformity issues, off-axis viewing issues with screens. You might as well be someone standing somewhere else in the room looking at the screen from some far off angle.

That is why people with triple monitor setups typically turn the side screens inward until they directly face them, so that the pixels are on axis , pointing directly at them. This is possible for nearly every pixel to be on axis horizontally with curved screens if sitting at he center of curvature, but realistically it's not possible on the majority of curved screens because the screens are too short vs. the curvature, or the curvature is too weak. I did sit at the center of curvature of the LG 45" gx950a 21:9 ' s 800R curvature while I had it though. 800R(adius) = 800mm = around ~ 32 inch view distance.

(says 1000R, but this works the same with any R value vs viewing distance)
