I know but someone said that was going to use an adapter.

Hi everyone. Good to be here with you.

I just joined (first post!) to throw my hat into this thread as I just got my 27QHD a week ago. I am living in Seoul right now so it wasn't a big drama if things didn't work out. Returns are 1 hour away on the subway. smile.gif

First, it was about $224.00 USD, so a good deal then.

Nothing was different packaging/contents/product-wise from the other photos that are in this thread (yep, I read them all before buying), so I won't post photos. I can tell you that you guys are getting the same thing that they are selling here, no fooling around. Smiley face, lovely fine matte, shiny black bezel, etc., right down to the cheap-looking/feeling power brick. I might get a more reliable-feeling one but I suspect it will be fine as well.

The local ad, which again has been seen on the net easily, offered 100Hz "real clock" out of the box, so that's what I did immediately after using the AMD pixel patcher and CRU. No problem with that at all; the monitor looks amazing, no dead pixels with just a hint of BLB, top left. I haven't taken it further yet in terms of O/C...in time. It rests at a smooth 96Hz right now, my new regular running speed.

Did all the frame-skip tests, etc and again, all is well.

Phenomenal picture, I have to say, coming from a 60Hz 1920x1200 24-inch "JooYeon Tech" (JT240WDB) monitor purchased here about 6 (?) years ago now. The colors, brightness IQ...really, really good; I am impressed. Great response times (I am a FPS player exclusively, casual gamer) with no anomalies (tearing, ghosting, etc) at all. IQ is sweet, especially with older games (BIG Unreal-series fan) with which one can crank out the frames, max out the settings...nice.

I am running an already-old 4770K (only O/C on boost to 4.2), 8GB GSkill (@1866), Asus Z87 Pro with a Asus 280X TOP card. Not a powerful system, but it handles the high res well. Yep, one loses hope of AA in most newer games, but the res is worth it, IMO. One tends to update graphics cards more often than monitors, and I see myself keeping this for a while. So, some more graphics horsepower for Christmas then?

Not sure what else to write except "thank you"s. To ToastyX first for the great software and to all of the folks here who helped cement my decision. Cheers one and all!

If you have any questions, fire away.

These will only work when connected via Dual-Link DVI or with an active DP-DVI adapter; HDMI-DVI adapters do not work.

I just got my 2795 from helloemart (http://www.ebay.com/itm/221902610837?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) and overclocked it to 96hz with an 24AWG monoprice dvi-d cable. I have an ASUS Strix 970. I get this extreme banding on the right side when the background is bluish. Decreasing the overclock lessens the banding but I don't see the point of a 15hz overclock. Is there any way to alleviate this? I'm guessing probably not and I just ended up unlucky but I thought I'd ask.

Can you (or anyone else) confirm this? Several (all?) of the 2795QHD items listed by dream-seller specifically say "Please use DVI-D port only. Cannot be used with DVI-I or DVI-S"

http://www.ebay.com/itm/Perfect-CrossOver-2795QHD-2560x1440-LG-AH-IPS-Non-Glare-27-Monitor-/321719207934?hash=item4ae7f587fe

I've looked through this thread and haven't found a direct answer to this (perhaps I just missed it)?

1] Is this true only for a dual-monitor setup?

2] Will this monitor work, full 1440p resolution and overclocking, on a DVI-I connection for a single monitor?

3] Most recent graphics card are only DVI-I (digital/analog); surely someone on this thread has tried single-monitor with DVI-I. Has it worked?

I've spec'ed for a new pc build and am getting ready to pull the trigger. However, I just found out that currently the only GTX 980Ti card with a DVI-D port is the Gigabyte one (it has both DVI-D and DVI-I). I may have to default to the Gigabyte card, or select a different monitor. Really, really don't want to pay $$$ for an ASUS or ACER. Any input would be appreciated.

Did you happen to try the stock cable? Just to check? Otherwise, you may have just got unlucky...

The monitor worked with both ports on my MSI GTX 970 ME100... one of them is a DVI-I and the other a DVI-D.

Yeah I tried with the stock cable as well. It's the exact same thing. I noticed the ASUS Strix 970 has a DVI-D and DVI-I. Plugging it into the DVI-I has the banding for darker blue colors (the previous pictures I've posted) while plugging it into the DVI-D has the banding for lighter grey colors. Perhaps it is my graphics card? I am going to test it with a different graphics card soon.

FWIW, I did lose 5Hz (110 to 105) of overclock moving from a hacked AMD 6970 to the Nvidia 970... so the video cards do make a difference.

My monitor looks great, no dead pixels.

I am overclocking it by adding a custom resolution in Nvidia Control Panel (not using CRU).

I can set it to 96Hz without any visible problems. At 110Hz I start seeing moving red dashed lines across my screen so I lowered it back to 96Hz.

The two issues I've noticed:
1. In full screen games, the monitor reverts back to 60Hz. I've coming from a VG248QE (144Hz) so it's very noticeable when it's running at 60Hz instead of 96Hz. Playing games in windowed mode solves this issue, but I'm still curious if anyone else has run into this issue.

2. Even when I'm running windowed mode I'll occasionally see "dips" where it seems to temporarily go back to 60Hz. It's not an fps drop from something demanding happening in game, as I have the fps counter up and it's a fairly old game (Counter Strike: Source) so it's pretty much always locked at 300 fps. But there will be brief moments where all my movements look choppy like the monitor is running at 60Hz before becoming smoother again.

Update on my situation. After applying Nvidia pixel clock patch (gtx 980ti) and using CRU, full screen at 96 hz (or at least it's not 60) is working. I also no longer see any of the temporary dips to 60 hz. I selected custom extension block, then edited that extension block and added a detailed resolution for 2560 x 1440p at 96 hz with timing set to LCD native (pixel clock is a bit lower in LCD native compared to LCD standard for me, not sure if that makes any difference).

There was a different configuration that I also got working where I used a combination of Nvidia control panel and CRU/pixel patch.
In CRU, left the extension as default, and just directly added a detailed resolution at 96hz. This refresh rate didn't appear in windows. Then I added the custom resolution through nvidia control panel at 96hz. In this mixed configuration 96hz was also working in full screen. Not sure what's going on here, seems it would be easier to just use only CRU.

In any case, thanks for the help.

In CRU, it did say that custom extension block must be used for Nvidia cards. In any case, glad it's all working out for you. And yes, I prefer using CRU because all the games acknowledge those settings. 980TI huh... so nice smile.gif
