Does the Samsung S27b970D overclock past 60hz? (1440p panel OCing HELP)

post #1 of 9
Thread Starter 
Hello guys, I have the chance to buy this monitor in the next 24 hours. I tried looking around and could not find any information on overclocking this specific display's refresh rate. I cannot order those Korean monitors and no 1440p monitors are available where I live.

I'm currently abroad and found the S27b970d for sale and would be interested in buying it but I really wanted to know if I could increase it's refresh rate. I hope someone who owns it or has seen a thread about this can possibly help me out.

I'm going to be using the GTX Titan SLI and the nVidia overclocking utility in the nVidia control panel present on the Titan drivers.

I'm worried because I can overclock my old E2290 1080p 60hz LG panels to 78hz, but my samsung S27a750D 1080p 120hz panel won't overclock to 121 hz for more than 5 minutes. It gives me a message saying "the signal input is not supported" after functioning and working properly for a set period of time.

I do not have access to my gaming rig, only a laptop with a 650m graphics card which is not capable of OCing anything (or so I think) so I won't be able to test it out, I also only have a HDMI port on it. I cannot return it to the shop at all as once I go back I won't come back for a while, warranty issues are not a concern for me.

At home I will most likely be testing out on a high quality Dual Link DVI cable and a Display port 1.2 cable.

I hope I've provided as much information as necessary, thank you very much for reading and for your help smile.gif.

It won't overclock.

I thought that the 850D did overclock, I've found multiple sources which is why I assumed the 970D MIGHT overclock. Could you provide me with a source or do you own one please?

I really would appreciate the response, and thanks for the reply smile.gif

I don't think the Samsung S27B970D can overclock even though it uses the same PLS panels as the QNIX QX2710 and X-STAR DP2710. Samsung must have locked the monitor so it can't be overclocked.

The 850 doesn't overclock either.

I don't own one, so I can't test it. However, there has not been a single report of a 1440p monitor with a scalar (not one!) that can overclock. Safe to say, the assumption is that until someone can prove conclusively that it works, it cannot overclock.

So the Samsung PLS monitors have scalers?

I guess they're really meant for professional photographers, photo editors and designers.

They have a scalar but all 3 of my 1080p monitors which overclock (LG e2290) also has a scalar. I won't risk it since my samsung TV and monitor doesn't let me overclock it, it works but it gives me an error message after a few seconds saying the input is not supported. My LG monitor has a scalar as does my sony tv yet they allow me to overclock.

Thanks everyone smile.gif

Also I've seen many ((I can explicitly remember two) forum threads about the 850D overclocking one claimed 82hz, but I won't risk it as I genuine hate playing fast past games at around 80hz or under, especially competitively. I do notice a large impact in smoothness and it ruins my experience personally. I'm really tempted to ship a Korean panel but I hate dead pixels frown.gif.

There's an old Samsung monitor 305T or something like that that's 1440p or 1600p I'm not sure, however but linus tech tips claimed and showed in a video that his could overclock to 70-80hz (I can't remember and I'm flying back today), however one of Linus' cats jumped on the monitor and made it topple over onto the floor and it broke. That monitor also had a scalar though so the scalar isn't the limiting factor.

Regardless thank you very much smile.gif

Being able to input >60hz signals does not mean that the monitor was overclocked. The big thing with the Catleap "2B" and the Qnix monitors is that they have been conclusively proven to *display* > 60fps when fed with a signal > 60hz. You can feed a monitor with whatever you want, but the vast majority of the time, the monitor will drop frames - ie, you feed it a 120hz signal, and it only shows every other frame.

I cannot remember seeing a single thread or post to that effect. Perhaps you could enlighten me? I must admit I haven't read every post, so I may have missed them.

Linus never actually checked whether the monitor was showing >60fps. He just fed it a higher hz signal, and said something along the lines of "It doesn't really seem different" - a key indicator that no, his monitor wasn't actually displaying > 60 fps. The "scalars don't overclock" idea arose out of the fact that "2B" catleaps without a scalar could overclock, but 2B catleaps with a scalar did not overclock at all. Actually, even shimians and crossovers without scalars could overclock too - just not very far. Yet add in a scalar, and it ran at 60fps no matter what.

The vast majority of monitors on the market have scalars. Monitors without a scalar are the exception.

Oh okay, thank you for enlightening me. I wasn't aware of the scalar affecting actual frames showed.

I also just stupidly assumed that the "I didn't notice a difference" (paraphrasing) was solely due to to 60hz to 70-80hz not being any different.

I'm actaully going to test this out tomorrow with a 60hz to 75hz monitor and I'll have to borrow a fast shutter-speed camera (I've seen this being done). Thank you smile.gif.
