Or loading a new page will momentarily produce some color blocks and tears until it finishes loading. Only started noticing this today. Doesn't happen all the time, just periodically. It's usually the case that my screen blacks out when my card's not being too active (like loading a new page, loading a game at the very start, loading W7, etc.), but now I actually see some funky stuff in between too.

Ok, I've run a driver sweeper to uninstall all previous nVidia drivers and registry entries and reinstalled Catalyst 12.6 beta driver - no issues now.

Also, at some point during my video card upgrade from a temporary 9800GT to HD 7870 and driver installations and reinstallations, I stopped seeing motherboard BIOS during boot and reboot. The first thing I see is now Windows loading screen. I do have ASRock Extreme 4 which boots super fast (and I minimized any extra things the BIOS checks for during boot, so it's extra speedy), which might be why I don't see it on time, but really not sure of the real reason. I used to see full motherboard BIOS load on the same board and 9800GT BIOS load preceding it.

I just got my Achieva Shimian Lite. Took 3 days to get to Vancouver, Canada. Perfect condition, no dead/stuck pixels, bought from Green Sum on eBay. I had been contemplating this purchase, and after reading over 100 pages of this thread, decided to buy it. I was just a little bit worried, but I can not be happier with it.

Has anyone jumped on the Potalion 27" 2710QW? Can anyone attest to its quality against the other monitors? Also how is BCC in terms of shipping and all the "jazz"?

Bought Achieva Shimian QH270 Lite from Bigclothcraft with the 110v-240v adapter, didn't notice any dead/stuck pixels yet, haven't looked too carefully, but if it doesn't me now, it's not gonna bother me even if there was one. Great monitor. The adapter does get pretty warm though, not even on the carpet.

The issue isn't the HDMI port or what the card can output on the HDMI side. The issue is the signal conversion from HDMI -> DVI.
Single link HDMI signals are identical to single link DVI signals, and this is true up to 165 mhz pixel clock. HDMI and DVI are fully interchangeable to this point.
However, beyond 165 mhz pixel clock, the DVI spec requires the use of a dual link DVI signal, and there is a little peculiarity of how it splits the signal between the two links; it is divided in two, but assymetrically split where the least significant bits of the signal are transmitted on link 2. Thus, although the HDMI signal itself is capable of handling the >165 mhz pixel clock, the conversion is much more complex. Theoretically, a monitor could accept a single link DVI signal at > 165mhz pixel clock, but again that's out of spec and not necessarily what the monitor is designed to handle.
So, for you to run a 1440p monitor through DL-DVI using HDMI, you need a hypothetical "active" HDMI -> DL-DVI adapter that does an deinterlacing of the HDMI signal into two composite SL-DVI signals to emulate the way DL-DVI handles 1440p image data. You cannot use a passive HDMI -> "Dual Link" DVI adapter, which simply maps the HDMI plug to a single link DVI plug.

Thanks for an explanation.

What about Catleap with HDMI input, would it accept 1440p or only 1200p by HDMI-to-HDMI (so no need to convert to DL-DVI)?


(If thats not possible, well, then I wont be able to get this monitor... oh well... Dell 2412M is for me then (1200p is still better than 1080p smile.gif ))

The Potalion I got was (almost) flawless!! Just some backlight issues (I think). It is weird because it is only noticeable on an all white screen and low brightness. As soon as I put the brightness at 50% or higher the problem disappears. The only real negative about the monitor was the stand, it is very wobbly. BCC was extremely pleasant to work with, he answered all my questions relatively quickly, he wrapped it in thick foam sheets, and the shipping was insanely fast. It was shipped on 6/4/2012 and made it to Chicago in two days!!

Sorry, I cannot really compare it to the other monitors, but the only real difference should be the brand, the bezel, and the stand.

Received my monitor from dream seller and it has a ton of dead/stuck pixels and flickers a lot!

I'm not interested in opening up the monitor either as although that'll probably fix the flickering, it won't fix the stuck/dead pixels.

Although the monitor looks brilliant, I can't live with it. There are probably 200 dead pixels on the whole screen, maybe even more. I can count at least 50 in the bottom left hand corner of the screen.

You can easily see them on a black screen using this test: http://jasonfarrell.com/misc/deadpixeltest.php

That SUCKS sad-smiley-002.gif Did you contact dream seller, if so what did he say?
Also can you post pics of the dead pixels?

I've contacted him but I've yet to receive a reply. It's only been 2 hours and he's probably going to bed though... I probably won't receive a reply till next week as it's the weekend for them now.

I'm a noob with my camera, not sure how to fix the exposure and I can't even find manual focus! Using a Panasonic GF3, the touchscreen on this camera is far too gimmicky, I don't know where half the options are.

EDIT: Just wanted to add, AMD A6-3500 with DP-> Dual link adapter works fine. For some reason when I got the monitor it corrupted my drivers and I couldn't even see desktop after booting twice. However, after reinstalling the drivers using my original monitor, things now work fine.

I can even play League of Legends with the integrated HD6530D on very high (no shadows) without dropping below 30fps! Now if only I didn't have a duff monitor.

I've gotta say, the glass is VERY reflective, with nothing but natural sunlight shining into my room, I can see my own reflection on black screens as if it's a mirror. Nothing wrong with that though as I expected it. When I don't load up a black screen the monitor does look awesome I've gotta say. There are quite a few dust particles, but I don't actually mind them, not noticeable at all compared to the 200+ dead pixels.

EDIT2: Recorded a video, will upload it to Youtube now.

EDIT3: It finished uploading and processing: http://www.youtube.com/watch?v=D4gP-Y2LVG4&feature=plcp

EDIT4: Just an update on the original monitor (Achieva Shimian from dream-seller), I've received a full refund for both the original transaction plus the returns postage to him. He decided to test it himself and didn't return it to the Achieva factory so I basically received my refund a day after he received the monitor. Brilliant seller I must say!

Awesome, thanks! I saw that a lot of people comment about getting the potalion, but no one actually commented about if they were good or not. I appreciate the feedback.
