Geforce Titan Monitor overclocking, the answer we've been looking for ?

[Annisman*]

This thread is specifically about the monitor overclocking feature of the Geforce Titan, that is what I want to discuss, and desperately want further clarification on.

For a few years now I have been wanting to increase my monitor resolution past 1080, however, as many others will agree, after using a 120hz panel it is nearly impossible to go back to 60hz.

And therein lies the problem.

There is no monitor that I know of (besides the catleaps) that are >1080 resolution, and capable of 120hz refresh rates.

So for many of us, we have been stuck twiddling our thumbs waiting for an advance in technology that just never seems to come.

With this new feature on the Titan, is it possible to get a 30 inch monitor (for example) anywhere near 120hz ? The way it is described in the preview is a bit confusing.

"Of course it goes without saying that just like any other form of overclocking, monitor overclocking can be dangerous and risks breaking the monitor. On that note, out of our monitor collection we were able to get our Samsung 305T up to 75Hz, but whether that’s due to the panel or the driving electronics it didn’t seem to have any impact on performance, smoothness, or responsiveness. This is truly a “your mileage may vary” situation."

They were 'able' to get their monitor to 75hz, but they didn't see a difference ? Could other monitors go higher ? Could we take 120hz monitors even further?

Who knows more about this feature ?

Is this the answer many of us have been waiting for ? If so, this feature alone makes splurging on a Titan well worth the money spent.

It's not something I would mess with on a good 30" or 27" panel. Overclocking your monitor can and does kill it if you push it too far.

If you want to burn out a $1200 30" or $800 27" to play with this then more power to you. Personally I would only play around with this on one of those lesser priced 27" Korean panels.

You can check this guy out, I think he sells panels that will overclock to a given extent.

Not unless your monitor supports it - of which the overwhelming majority will not. The ability to overclock is already present - it is just receiving some official support in drivers.

For example, there was a "125hz overclockable" Crossover being sold on Ebay. People got it and tried to overclock it (by using the current driver hacks and such). The monitor was clearly receiving 125 fps, but it was dropping 65/125, and was only displaying 60 fps. So it doesn't matter what you send to the monitor - if the monitor doesn't accept >60hz signals, it cannot display them.

It basically makes it easier to overclock your "2B" catleap/Overlord monitor... and whatever miscellaneous monitor that is discovered to be able to display >60fps.

That's dissapointing to hear, would this feature make it even easier to overclock those Korean panels ?

My understanding is that it is the PCB design/hardware that makes it possible for the monitor to overclock. I don't know if the panel itself is relevant or not as well, but the PCB has to support it.

I just find the whole thing odd to be encouraging. This can damage your monitor and there are bound to be a few people who try this and kill their monitors.

 

[Annisman*]

Well, looks like I'm going to have to pull the trigger on one of these tempest monitors, what's the deal with them ? He's sold out right now, do they go quickly when in stock ?

Does this guy order a bunch of panels from overseas and then test them one at a time before selling them, is that the general idea ?

For what it's worth, my "2B" catleap is coming up on a year. One month to go...

Linus was able to get his 30 inch monitor to over 80hz using the new monitor oc feature.

 

[njdevilsfan87]

How does the Titan monitor overclock feature work any differently than just making custom resolutions in NVCP?

 

[kevinsbane]

Linus was able to get his 30 inch monitor to over 80hz using the new monitor oc feature.

Did he check to see if it was actually displaying 80fps?

 

[Annisman*]

How would you even do that ? And what's the point of the feature if it doesn't end up doing what it says. I feel like if the Nvidia CP says it's at 80hz, then it should be actually displaying 80hz.

 

[kevinsbane]

You would need a tool like the refresh rate multitool.

Many (most?) Monitors simply drop frames when you feed them with more than 60 fps.

I remember trying to OC my CRT some 10+ years ago using PowerStrip

my current 60Hz screen stops working at around 65 lol

This should make it much easier to do HDTV refresh rate overclocking to 120 Hz.
Overclocking an HDTV to 120 Hz native from a computer

Some HDTV's (e.g. Vizio e3d420vx) can be forced to accept a 120 Hz external signal, even though most HDTV's usually can only do 120 Hz internally (e.g. frame interpolation). It actually worked, motion looked smoother, and wasn't framedropping.

Regarding computer monitors: I also was able to overclock a 5-year-old Samsung 245BW to 72Hz once (using PowerStrip). Motion actually looked slightly smoother (albiet only about 20% smoother). Enabling LightBoost has a far more massive effect (PixPerAn tests showed 92% less motion blur than 60 Hz).

Yeah, except who the heck is putting a Titan in an HTPC. I've got a GTX 560ti in my HTPC, and that's overkill as it is.

 

[Annisman*]

Also, going into my Nvidia CP and setting a custom resolution, I can already set a resolution+refresh rate higher than my monitor. What exactly is Titan doing differently that the NCP isn't already allowing you to do ?

 

[Mark Rejhon]

Indeed. You can still use a GTX 560ti with HDTV refresh rate overclocking, just need to use the PowerStrip method, or the complicated EDID Override method. Fortunately, I think PowerStrip supports 560ti for easy refresh rate overclocking.

Cool I may try it

Hey Rejhon, can you give me any pointers on using power strip ? Having difficulty figuring out how to get my Plasma overclocked a bit.

I've got a Panasonic Viera 55 inch.

This one: http://www.amazon.com/Panasonic-VIER.../dp/B00752VKSC

It's '600hz' capable, whatever that means, but I am currently only seeing 60hz as an option.

Take a look at:
HDTV Refresh Rate Overclocking Guide

You need to use PowerStrip's Custom Resolutions feature to add the 120 Hz mode. However, if the Custom Timings and Resolutions feature in PowerStrip is disabled (e.g. newer Geforce cards), then PowerStrip does not support your graphics card, and you must use the EDID Override method instead of PowerStrip.

The 600Hz refers to a plasma subfield rate, and does not necessarily pertain to actual motion refresh rate you can overclock the HDTV to 75Hz or 120Hz. I have heard of someone who successfully overclocked a Panasonic VT50 plasma to 120 Hz from a computer, but this is only one 3rd party report (link found in comments at the bottom of the guide)

One warning: It is guesstimated only about ~25% of active 3D-capable HDTV's can successfully overclock to 120 Hz. (The ones that do 120 Hz internally, and otherwise accept a frame-sequential 3D signal). You will generally find maximum success with 720p@120Hz, because that's the same dot clock frequency as 720p 3D glasses@60Hz.

How do I overclock my 22" 1680x1050 Samsung 2253BW to 75 hertz? It's native is 60 hertz.

Edit: I tried a mere 75 hertz and the display was all mucked up. I'll just save up for a $400 27" 120 hertz monitor.

Wowowow!!!!!!!!!!!

Overclocking HDTV's!!! Never seen that article! :thumbsup::thumbsup::thumbsup:

So, what's the best oc'able-to-120Hz 42" HDTV that I can get for say, under $400? :biggrin:

Because I'd buy one in a heartbeat!!!!!!!!!!!!!!!!!!!!!!!

I still have two Sony GDM-FW900's, mainly for refresh rate and resolution scaling up to 2560x1600 @ 69Hz... from 1440x900@120Hz (ideal for S3D, although there's ghosting).

Thanks for all the tips +1 hypothetical rep for you!
