did you think the 60 to 120 was bigger or gsnyc?

After I de-matte it of course. biggrin.gif

This is a thought I had as well, glad you commented. With displays, it seems there is always a trade-off of strengths.

In my experience with the VG248QE, I had troubles going from 120hz w/ LightBoost to 144hz w/o LightBoost. To me, even at 144hz, the motion blur was evident in comparison. I just don't know if I can go back to non-strobe despite the lack of brightness!

I'm thinking that likely the XR341CK will have a similar configuration... Looks like my FPS target will be >100 instead of >144.

I think GSYNC was a bigger change to me. I was used to Lightboost 120 Hz for a long time and when I tried GSYNC out on the Swift I was surprised by how well it handled. I rarely use ULMB mode on my Swift now because GSYNC gives me nearly all the pleasure ULMB/Lightboost has, but without the lose of color due to strobing. I just wish we had more inputs on a GSYNC monitor, even if we couldn't use GSYNC/ULMB it would;d be nice because then I would replace my Dell with it and have 2 epic monitors side by side, the Swift and the Predator.

Yup. 60 Hz is hard to go back to. Sadly I can tell even on the desktop just by the way the mouse cursor moves. Otherwise 60 Hz isn't bad for a monitor that is used as a TV/media. That's why I still use my U2711.

Haha, awesome! You guys won't regret the purchase, but definitely report back how it goes when you guys get your colorimeters in and have had a chance to calibrate! thumb.gif

Spyder colorimeters (especially the Spyder 3 since it does not support LED back lighting) are inaccurate and can't read contrast properly either which is why Callman, Spectracal and none of the good monitor reviewers use them.

The x-rite colormunkie is the only cheap worthwhile colorimeter, plus it can be used with dispcalgui+agyrll which is free as well as one of the best programs for calibration.

Thats a little pricey for a Swift IMO. I have seen them go as low as $539 used, at different websites.

Any chance this will be lower than the current $799 through Acer once it hits other retailers?

Been itching to possibly replace my Apple Cinema 27 I've had since 2010 and torn between this (used to be a Swift) and a 34 inch 21:9 1440 monitor....

If you're going to invest in an IPS display, especially one the price of the XB270HU...i'd highly recommend spending a bit extra and springing for a colorimeter to fully calibrate your display. Something like a Spyder4Pro, or an earlier version would be a worthwhile investment. I'll probably set everything on all 3 of my XB270HUs when they arrive to 50%, and then adjust the settings for each one individually according to my Spyder4Pro.

Colorimeters make a tremendous difference in color accuracy and I would neve:thumb:r own another monitor that wasn't adjusted by one. I couldn't believe how off my Shimians were before I calibrated them...just worlds apart in terms of gamma/color reproduction. Not only that, but it's awesome that the Spyder software will automatically apply saved calibration settings per-monitor if a game or program randomly resets the calibration settings. thumb.gif

I have an i1 Display Pro, I like it more than the Spyder 4. The Spyders are quite slow and I must say the Spyder software is a bit too simplified (I own a Spyder as well). The i1 Display Pro software will also lock the GPU LUT for each monitor so it doesn't get changed.

While software calibration is great it is no substitute for a good factory calibration.

With a software calibration you are changing the 8 bit values sent to the monitor to adjust the color displayed while with a good factory calibration you can still use the full 8-bit range. If you need to change the color too much with software you often get banding as 8-bit simply isn't enough precision.

I used to generate a profile for absolutely every display I came in contact with but after more experience with different displays I got a bit more relaxed and now I try to tune the OSD options using the meter to get a setting where I do not need to use a profile in Windows. Of course on many monitors I still need a software calibration to get decent results but I am hoping this one will not be one of them. Good settings on the monitor can look better than using a software calibration, depending on how accurate you need the colors and what you have to give up to improve the color accuracy.

Having a meter to adjust R, G, B, and examine the effect of changing brightness and contrast is excellent but don't assume a profile will always improve things in all ways. I use colorHCFR to examine the effects of changing settings and applying a profile.

Both Sypder and i1 Displays Pro calibrate for graphic design workflows and do not have enough options so I tend to use Argyllcms (open source) as I am calibrating for games and movies, not graphic design. It always takes me some tinkering to find good settings for a new display. Argyll can also generate a 3DLUT for madVR which offers a much better calibration than the simple 3 1DLUTs of a Windows profile.

If the XB270HU has a 2.4 BT.1886 gamma and <2 deltaE color errors I don't think I will need to use a profile on it. I really want to know how the gamma was calibrated. tongue.gif

The others listed there cost way too much lol

 

Looking at the X-Rite prices it costs about ~40€ more than the Spyder 4 Pro, I'll have a better look at both. I still have quite some time before the 21:9 predator gets released anyway :p
