Overlord Tempest X270OC

This list is what i have found of 2560x1440p 120hz monitors

QNIX QX2710 Evolution 2 ....... 27″ 2560×1440 ~90Hz – 130Hz
- X-Star DP2710 ....... 27″ 2560×1440 ~90Hz – 130Hz
- Overlord Tempest X270OC ....... 27″ 2560×1440 ~90Hz – 130Hz
- Overlord PCB Upgrade ....... 27″ 2560×1440 ~90Hz – 130Hz
- Catleap 2B ....... 27″ 2560×1440 ~120Hz

You will not be able to use nVidia 3D Vision with these monitors. These monitors have a refresh pattern similiar to this (high speed video). 3D Vision requires an LCD that can refresh faster, similar to this, an LCD that doesn't bleed refreshes into adjacent refreshes. (These high speed video were done by pointing a high speed camera at TestUFO: Flicker). It's worth noting that overclocks only have about 50% less motion blur than 60hz LCD's, while LightBoost displays can have more than 90% less motion blur than 60Hz LCD's. But at the cost of being limited to TN panels and being limited to 1080p.

That said, Overlord can come with an overclocking guarantee and less potential for image quality degradation during overclocking, while the QNIX much cheaper, can be a little more random (not always possible to overclock, and can cause some strange artifacts). The Overlord can be useful for "cost is no object" situations where you want 1440p with a 120Hz guaranteed overclock.

How do they have their monitors with a guaranteed 120hz overclock? Do they personally make sure?

AFAIK the Catleap 2B and the Overlords using the same panel may have artifacts in the form of lines, noise, or jittering when overclocked. Not sure about the other models. That and the lack of dead pixel warranties are really the only thing keeping me from buying at least one.

I believe you are correct in that regard Mr. Pixel, they do use the same LG panel, I heard of these weird lines and other occurrences, but I can't recall exactly if ToastyX created a program to fix the horizontal lines. I would of gone with Overlord but the 1 year warranty was a big bummer for me. Though, you can go the Korean monitor route, and purchase a square trade warranty with it. I was recently looking at a QNIX Qx2710 pixel perfect on Amazon and 3 year square trade warranty to cover it, I want to say the price was just a hair over $400. If I'm not mistake the Overlord was well over $550.

I believe ToastyX does have a line remover, but IIRC that only works in windowed mode at full-res. There seem to be 2 different line artifacts: Every-other-line banding that is fixed, and lines that flicker or shift position. I don't know how often each occurs, and some people are more observant of the problems.

Keep in mind that the "pixel perfect" monitors do not guarantee no pixel defects. All it means (despite the name) is that you'll be guaranteed less than something like 5-10 defects depending on what type and where on the display they are. AFAIK none of the overclockable sources offer a genuine defect-free option.

If you do get one of these displays, please consider leaving feedback on your overclocking experience.

There are a few factual errors in this thread, guys.

1) Unless something major has changed recently without any announcement, I can comfortably say that Overlord Computer does NOT 'guarantee 120Hz' on their Tempest X270OC. They test a minimum 96Hz overclock but not 120Hz. Some people get 120Hz, some less (some more), but 120Hz itself is not guaranteed. Always read, understand and accept the terms and conditions of a retailer's own website instead of accepting what you read on internet fora. There are some very well-informed people out there, especially on here, but details often get lost along the way, or indeed change outright.

2) The 'noise' that sometimes accompanies an overclocked X270OC or Catleap 2B is due to vibration of diodes on the TCON board. It does not affect all screens, and it affects some more than others. It can be mitigated/eliminated by applying epoxy to the offending diodes. I have done this with success, and without destroying my monitor, despite being all thumbs.

3) ToastyX's excellent Deliner tool (on MonitorTests.com) only works in desktop with Aero enabled. Applications that have exclusive access to the screen - like games running at full screen - cannot be corrected with Deliner however I have to say that the scan lines that come with overclocking my Tempest are effectively impossible to see in a gaming environment anyway

Not sure where you're located, Beefcake, but if it's US I recommend going with Overlord for the local warranty, support and peace of mind. They're also offering a free shipping deal to CONUS customers until 10 September as a sort of birthday celebration: http://overlordcomputer.com/pages/birthday-sale

If you don't care where you get it from then the PLS screens are worthy of consideration due to their low price (but be sure to install ICC colour profiles and use SweetFX, as OC-ing these panels dims the colours)
