Ok so I've gotten my monitor to overclock stable at 120hz at 489.60Mhz pixel clock. I'm sill slowly messing with the total pixels to rid the monitor of scan lines. but no matter what setting i have CRU at my top right corner of the monitor is still slightly darker than the rest of the monitor. What setting should i adjust to try and fix this?

I don't think anyone here is really certain on what you are seeing. The way you describe sounds like PLS glow, which is normal. I haven't heard of it being better or worse between monitors, only backlight bleed which should be in isolated regions. Like i mentioned most people here are checking for pixels and backlight bleed, not PLS glow.

What? He opened his monitor and damaged the backlighting element. Now he should be able to RMA it? No wonder these ebay sellers don't accept returns rolleyes.gif

Well if a destructive event occurred like opening up the panel and working on it then maybe the led strip on the left hand side has a short in it and the leds aren't being lit up on the left. Did you try a black screen are you getting white in that area or is it still black when you load up an all black screen? If its still black it looks like you have dead led edge lighting strip/short along the edge led lighting strip/traces most likely from a pcb inside in the panel you broke. Its always good to troubleshoot based on what you know has happened to the panel. If it was fine before you opened it and then you open it and put it back together then its possible you broke something. First time we have seen this. I was thinking it was typical BackLight Bleed in reverse due to a polarizing effect from a bent internal panel frame. Now I'm thinking its dead LED lighting strip PCB. Looks like time to try a return or something. I don't know maybe theres more to it you have to figure it out. I've been looking into modding the LED light strip and it isn't as easy as it looks. You have to get the exact right LEDS light, power, heat, the ones we have in ours are small flat SMT type leds on a strip something like this http://www.youtube.com/watch?v=y16IndYR378 http://www.amazon.com/Ub54255led6420x2-Replacement-Industrial-Originally-Compatible/dp/B006M53OBO which is a ripoff or this http://www.youtube.com/watch?v=LWWk_zUncCo. Or if you want to take the genius route http://www.mp3car.com/lcd-display/43743-800x1280-narrowscreen-8.html; wrong color, wrong output, wrong heat(equally stupid overclocker watercooling to boot), and after he spent over 500 in water cooler raw materials alone and with LEDS the whole thing over 1000 dollars he gets a yellow washed out gunnar optics urine screen. Sourcing the LED strips is not easy unless you work in that industry.

This board looks exactly like internal QNIX/X-Star Board and even has the same Pixel Clock DVI Signal chip the EXPLORE(Same logo) must be EP269(only DVI chip they make according to their site). So it must be functionally the same if not identical. I need to open up the panel and take some high resolution pics of all the boards and internals so we can have them for reference at such a high res and in focus so all components can be read easily 24 MPixel would be nice. Still that board is overpriced no way those components cost 200 dollars tho mass producing those boards I'm sure cost a pretty penny I don't know if it justifies that kind of markup. Did QNIX(HyoSung? HYO manufacturer from EDID Use EDID manager free download to read EDID info) copy overlord or did overlord buy some cheap asian boards and are now selling them here in the west for ripoff prices? They mention a TCON board is also included which is different from the Inverter board attached to the back of the panel is it apart of the same overlord PCB or a separate part not pictured? Would be nice to have a Crossover Black Tune 2735AMG/2755AMG or ACHIEVA Shimian QH2700 Lite Edge Bezel tho the silvery metallic at the bottom of the Crossover would be distracting(looks cooler overall but would be distracting as hell watching movies) and the Shimian while it has a nice bezel I don't like either of the stands. I wonder if Black Tune means better black level. Still the cost of these monitors plus the board would put you around 600 bucks(not sure if just a bezel alone is worth double the price). I like the color scheme of LG IPS more the Sky Baby Blues and Orangy Reds but I don't think it works with LCD contrast ratio(but it looks nice and sunny and bright and more real on CRT contrast ratio higher contrast ratio means more of an ability to recreate a high dynamic range effect like in video games) to me it comes off looking washed out and cartoony because of IPS' lesser black level of course I haven't seen them side by side I'm just going off instore comparisons I have seen between all the major brands(LG,Samsung,Sony,Panasonic,Vizio) which seem to hold true across the entire lines.

Seems like both Shimian and Crossover have 2560x1080 variants which look to be brand new. I still dont think 1080 vertical resolution is enough for the pixels to disappear tho the lower GPU load plus higher FOV console tweak would be nice(which allows the tris to be pushed further from the foreground making them smaller decreasing overall graphics load increasing the speed of ingame movements and greatly improves strafe jumping(if allowed by game physics)) to improve overall awareness. Also this would eliminate black bars in movies but would add them to HD aspect TV show content like Breaking Bad and Dexter while it is possible to crop the sides of movies if you crop the top and bottom off HD content you end up with chopped off heads. They are a little pricey coming in at under 500 but at 29" its 698x402x160mm compared to 654mm x 491mm x 160mm for the 27" 2560x1440 Shimian roughly the same size the 1080 is 4/5s the height but an extra 14th the length 1.067278 so its smaller. I bet the Overlord PCB can be adapted to these as well.

Also trying to find some info on these internal panel DVI looking cables. Are those FPD-Link III cables? Tried to google up some pics but found nothing. Would really like to be able to source those parts if I had to or at least look up some specifications so I can make some of my own(they felt very fine not sure I want to attempt it).

Looks like the TCON is the lower board and the inverter boards are the skinny boards on the very edge of the display on the back the one that attachs to the mainboard pixel clock board is the TCON board underneath the metal cover on the back of the display. For some reason the overlord(which states in the comments its the exact copy of the Catleap 2B board) only has one chip while ours have 2 of the Wise View LRU4122MOL-Q Chips. He also states the overlord has OSD so maybe its a little nicer than ours.

Hi guys,

I've been looking into getting this monitor..but just to be sure: is this the one to get (I prefer pixel perfect)?

http://www.ebay.com/itm/Perfect-Pixel-FREE-EXPRESS-X-STAR-DP2710LED-27-2560x1440-Samsung-PLS-Matte-/321135502506?pt=Computer_Monitors&hash=item4ac52ae4aa

Any differences from the QNIX version at all?

Thanks!

Your point about the PCB is very interesting. If it can be proven that the board in the qnix is identicle to the one overlord is selling it is going to be pretty bad (as the Qnix is only 100 bucks more and the board is likely a non impactive price point meaning it is likely less than 25). I honestly expected the 2560x1080 variants to emerge at some point but i can say i am a bit dissappointed regarding the price(almost 200 more for less when compared to our monitor mostly). Playing widescreen movies with a more appropriate aspect ratio would be nice but as you said this would not be ideal for standard content(unless you are working on half and watching on half).

Yeah that is fine. The only thing to look for is there is multiport models now but they will generally have DP in the model indicating they have a display port plus whatever other port. If you want extra ports that is fine but single port displays seem to have a better OC.

Keep working to push the pixel clock down. This will help uniformity. Also try a bit higher brightness. I also found the quality of the cable obviously makes an impact as it is correlated to the pixel clock size.

This is going to be more dependent on your location rather than the seller. Many in the US have not had to pay customs(except for like California and other states with laws regarding online/oversees purchases)

If you can find a EP269 board for sale directly i would think it is going to be worlds cheaper than overlord and per that last post by ColdFlo could be the same. I have not had much luck finding it yet but duplicated efforts may help our cause redface.gif

Watch out for the pixel perfect policies; most of them are not accurate. They allow for, let's say, 1 dead pixel in the center and 3 dead pixels in the surrounding areas. Of course, policies differ between the sellers, but up till now, the best (true) pixel perfect policy I've found is at accessorieswhole. These guys actually understand the difference between stuck and dead pixels and inspect the monitors using different color backgrounds, not only black and white. They offer ZERO dead and stuck pixels. They are the most expensive of the bunch, but they are very highly rated and their customer support seems good.

@Spartan F8: I think we should ask the sellers where they get their replacement PCBs from. There were a few incidents where they shipped replacement PCBs to customers who had certain issues. Anybody asked any seller for a replacement PCB and got lucky to buy one (or at least receive a price or know where to buy it from)?

That would be good to know but even if you google "EP269 450mhz" you find a few data sheets and mostly our postings on various sites. My best guess would be these guys mainly because all other relevant links juts about always link back to them: http://www.epmi.com.tw/sayapro03.php?id=93

And this is a neat little data sheet i found on it(sort of) http://www.ineltek.com/ru/files/Explore_company_profile_2010_10.pdf

As far as purchasing it appears to be bulk ordering only from what they told me on the phone(or tried to tell me as they had very broken English). This is not feasible even with a group buy as it would not fit the quantity(unless you are overlord *maybe not confirmed yet*).

What do you most of you guys do with the X-star after shutting down your pc? Do you let the monitor stay in standby mode and blink blue or turn it off with the button? redface.gif
