From the power brick to the wall socket I have tried both the korean plug with the international adapter, and a spare US power cable that I had laying around. I have made sure that both ends are firmly and securely plugged in.
I am using a 7970 Vapor-X 6GB edition AMD card.

Are the Crossover 27Q LED superior to the SAMSUNG SyncMaster S27A850D?
Also, what makes me hesitate to pull the triggger on a 1440p is obviously the response time of these monitors. I'm not an extreme-hardcore gamer but I'm an enthusiast gamer and I play FPS among other games... I don't want my controls to be mushy, evn slightly... I don't want ghosting or things like that... I hear conflicting info on the 1440p monitors, with some saying that the latency is not noticeable at all and gaming experience is top-notch, others saying the opposite...
Can you guys confirm that a Crossover 27Q-LED (I choose only that one so I avoid input lag) is really A-OK for gaming? Have you compared with a TN low-response monitor? (I play with one for now).


input lag is less than the 1440p competition because the non multi input monitors don't have a scaler. Input lag is about the best it's going to get on an ips 1440p monitor with any korean. No one here really recognizes significant input lag on any model really. There has been input lag test done on these forums either in this thread or the catleap against the 1440p competition.

also the samsung isn't an ips panel. it's their own tech.

Ah, thanks for the info on the scaler, very useful indeed. But.. If they don't have a scaler, how do they behave at other resolutions? Blu-Ray or DVDs display?

Also, Tthe Samsung's input lag is equal to zero according to this review of the Asus PB278Q that uses the same panel.

The Samsung SyncMaster S27A850D is a good 1440p and it's the less expensive in my country; indeed it uses a Samsung PLS panel while the Crossover and the Koreans use an IPS LG panel.

I've done research on monitors lately, and I had many surprises. Here's a review of the Samsung. The guy really seems to know what he's talking about (I think he contributes here at OCN). I've read several reviews and apparently the site Prad.de is a reference in monitor testing, as they test the latency / response time with an oscilloscope instead of SMTP so they have the best results... and the results are surprising... They say the Samsung S27A850D is "very good" (the best note, after "good", "satisfactory", and "sufficient").

As for the Korean monitors, unfortunately they only tested the Shimian QH270, which they noted as "satisfactory" (a not-so-good review) , the latency time was longer (very long, almost 24ms total) and the overall performance a little disappointing... Now the latency time on the Shimian may be due to the fact that it's a multi-input model, I know I'll only buy a single-input model. Though I think input lag and response time are different things?

Using other measurements, the Crossover 2720MDP (Multi-input) showed inferior response times, slightly better than the Samsung in these reviews: Samsung and Crossover

Still, I would think that a good Crossover unit is better in terms of overall display quality than the Samsung.

Have you compared the Crossover with other monitors, such as TN panels? Are you an enthusiast gamer? You don't notice any latency, the controls are not mushy, no ghosting, no blurring, nothing? At all? Sory for all these questions, I want to be sure before pulling the trigger on such a thing.

The Samsung has 13.6ms of input lag (see prad.de's review). Almost all of Hardware Info UK's input lag measurements are wrong, but close. Prad.de uses an oscilloscope and provides the most accurate results, followed by overclock.ru (smt tool 2.5) and myself (smt tool 2.5, I am the author of the wecravegamestoo reviews).

Pixel response times (ghosting) and input lag are separate (delay we feel). The CrossOver 2720MDP has low pixel response times, but a properly over driven TN panel will always win. It has 13.6ms of input lag over dual-link dvi like the Samsung.

The ViewSonic VP2770 (see prad.de's review) has faster pixel response times than the Samsung and only 7ms of input lag (which is negligible) making it the best for gaming as well as factory calibrated colors. The 2720MDP's are big dice roll in terms of image quality since IPS colour preset quality is basically random on some models (including the Koreans).

It is just played back at 1080 at on 1440p not really going to change anything, but I don't watch movies on my setup.

and I have compared them to my 26" lg tn panel and my 120hz acer 3d tn panel. my crossovers smoke them so bad it's not even funny. The difference is like going from a tube tv to a lcd back in early 2000s. Maybe not that drastic but 1440p ips > tn.

these are advertised at 6-8ms response time. but i think it's more around 12. not like that's going to stop you. if 12ms effects you than you need to stick with 1080 tn panel. you aren't going to notice it. Even the 2ms advertised tn panels are NOT 2ms.

I guess I am an enthusiast, but at same time I'm stupid for spending as much money as I on it all for 7680x1440 surround.

Hey, very glad to see you there, I know it was you who wrote the reviews, as I said in my posts - I couldn't find your original posts on OCN.

As I said, I already knew that prad.de uses an oscilloscope for more accurate results thanks to your reviews (great work BTW thumb.gif). I also knew that pixel response time and input lag were separate, as I also said in my post, but now I have a very important question: I wonder, do we have to add up both to have the total latency then? If the Samsung has say 13,6ms of input lag and up to 19,3ms of pixel response time, does it mean it has 32,6ms of total latency? So should we add input lag and pixel response time for each tested monitor to know the true latency?

Uugh The Viewsonic seems really perfect but it's way over my budget, unfortunately. You say the 2720MDP is a "dice roll" but what about the 27Q-LED then? I guess it would be the best of all Crossover monitors in terms of latency right?

+ Repped for your great contribution.

Oh yeah I know full well the advertised latencies are not the good ones. Even the hyper-hardcore gamer monitor Iiyama that everybody praises for being hyper fast is announced at 1 ms and is measured as a total of 7,6 to 10,2 ms in prad.de
.Well you certainly manage to convince me for these Crossovers lol. You sure seem so satisfied, I would jump on these things with eyes closed. Have you been lucky to get three without any problem? Because in this thread I've read several people receving faulty or poor-performing units.... That being said I highly value your testimony. If there was a trick to be certain to have a good one.... Well, when I look objectively, the amount of dissatisfied people is close to the amount of dissatisfied people in any review for any other monitor. The only thing is, if it is defective, shipping a huge screen to Korea is an adventure. Plus the customs, etc...I won't repeat myself again and again. Anyway, thanks for taking the time to answer all my questions, I've also repped you, you've been very helpful.

monitor failed this evening. black lines appeared, desktop then began to fade, until nothing was visible but the backlight. tried several power bricks (from doublesight monitors, which have much more rugged transformers), different gpu, cables, tried the monitor on two other dual dvi capable systems. as soon as the monitor 'warms' up, the screen fades, does it in bios too...sucks. it looks like a perfect panel too...

that's not good, how long have you had the monitor.
post #4289 of 6483
most of the people who have had problems, didn't buy them from the best seller and if they did. they were promptly taken care of with receiving new monitors or pcbs. Only issue I had was one of the power supplies died and AW shipped me a new one in a day and half just like them monitors for free.

You shouldn't have to replace PCBs in your monitor D:
