BenQ BL2420PT 24 inch QHD 1440p IPS Monitor | 100% sRGB |AQCOLOR Technology for Accurate Reproduction for Professionals

Comment

I do not have access to calibration tools, so this review is based on some Lagom tests and my eye perception. Technical details can be found on the BenQ official website. The good: - solid and fully adjustable stand, not wobbly at all. - lighter and thinner than BenQ BL2710. Looks almost the same as AOC Q2770, except for the glossy bezel. - light AG-coating, pictures are clear and crisp without the somewhat annoying reflection on my old Acer H236 (full glossy). I do notice very minor amount of cross-hatching when moving my head, but its definitively much less severe than some older monitors with heavy matte coating. Most people probably wont notice it at all. (9/3/14 update: it seems that the cross-hatch effect is only present within 10 minutes of usage. After that, I cannot defect any cross-hatch. So maybe the artifact is related to monitor warming up?) - full array of inputs. HDMI works for 1440p! - 8-bit color (10-bit via dithering) reduces banding compared to my old Acer H236. A good test would be a sunset picture: http://wallpaperscraft.com/image.php/63366/2560x1600.jpg If you look at the sun and the surrounding, my laptop (crappy display) shows no gradient, my Acer H236 shows gradient but also the transition between colors (visible banding), the BenQ displays a smooth gradient. - mostly uniform color and brightness (by naked eyes). - balanced overdrive setting reduces ghosting without overshooting(compared to Acer H236 that doesnt have an overdrive setting). - OSD control by solid click buttons. Power light is on the side and does not distract me when viewing dark movie scenes. The bad: - significantly more IPS glow than Acer H236 (when viewed off angle, especially when viewed from above) that interferes with dark movie and game scenes (because the screen is so large, when my head is at the same level as the center of the screen, Im automatically looking down at the lower corners of the screen). - some bleeding in the corners. The lower right corner is even a little yellowish. (for me bleeding is when you view the screen straight on and IPS glow is off angle). - black uniformity is not as good as BenQ BL2710. The GW2765HT I received showed some cloudy gray on a full black screen (powerpoint). A side-by-side comparison with BL2710 at the same brightness setting made it very obvious. - no matter how I adjust the gamma and contrast, the monitor did not pass the Lagom white saturation test (253 is very faint, cannot see 254 at all). My old Acer H236 can easily display all the squares in both black level and white saturation tests. - color distortion at off angle is slightly more noticeable than Acer H236, partly due to the increased IPS glow. The ugly: - three(!) adjacent(!) stuck (red) pixels in the center area (area 5). Noticed them the moment I turned on the screen because the BenQ logo screen has a blue/purple background. I also noticed that its more than one because of the perceived intensity, so I took out a magnifying glass and counted the pixels. This is extremely annoying and distracting because my desktop background is solid black and I use the monitor mostly for movies and games (lots of dark scenes). After search the web a bit, I found jscreenfix, and running that for 1 hour "fixed" two of the three pixels, but the last one remained stuck. However, this was only a temporary fix, as leaving the monitor off for a day or two will cause the "fixed" stuck pixels to re-appear, and they seem to be reset to the factory setting (100% brightness!), making them extremely distinguishable since the rest of the screen is set to 0% brightness (yes, 0%). Returning the monitor now.... Other thoughts: - came with random assortment of cables (mine is missing the DVI and audio cable and has one extra HDMI cable). - 10-bit via dithering. As a 27 1440p monitor, 8-bit is really fine. no one is expecting true 10-bit. According to some, dithering could also contribute to the cross-hatching problem, but overall the cross-hatching is very minor. (9/3/14 update: see above for the cross-hatch problem. Lagom test black level test shows no apparent dithering.) - slower response than my old Acer H236 (about 10-20 ms slower by a Lagom test). I consider this neutral because most 1440p IPS monitors out there are in this response range. I did not experience any lag in FPS games (single player), but I am not a hardcore gamer. - on the box it says IPS, but most likely it uses an AHVA panel manufactured by AUO. Some Australian forum users speculated that it uses the same AHVA panel as BL2710, and GW2765HT is basically BL2710 with reduced functions (no USB, CAM/CAD mode, not a "SolidWorks Solution Partner Product" (whatever that means...)) intended for home users. - the build-in speakers are not as good as those on BL2710. The verdict: - if it were not for the stuck pixels in the center area, I would have kept this monitor despite the IPS glow. Overall it has a solid build and vivid colors, and the pricing is very competitive (currently cheaper than Asus PB278 and AOC Q2770). 9/3/14 update: I decided to change the rating from 3 to 4 stars to reflect the rating I would give if the particular sample I received didnt have pixel problems.

Great monitor. so far no issues or complaints. Not using it for gaming. Connected to iMac 27" w/retina and after calibrating colors looks very similar. For those who are looking for settings to color-match Macs display, here are mine (connected using miniDP to DP cable): Picture mode: user Brightness: 14 Contrast:50 Sharpness:5 Gamma:3 Color Temp: User defined: R:91;G:86;B:95 Visually it seems to match retinas color reproduction pretty closely. Using apple provided non-modified display profiles. Hopefully this helps someone.

I like BenQ monitors, have several of a different monitor. I needed reasonable monitors for work and grabbed these. One of my setups has 2 computers that I have going to these monitors and I need the display to auto detect which inputs are live and go to it, well this display has issues with even figuring out which input to grab with just one computer attached. Once you fight with it long enough you can get it on the desired input, but it does not auto detect. Picture is great, but versatility sucks if it can’t auto detect a single input and switch to it. Updated: So it seem these monitors do not auto detect signal to switch inputs. Which is fine except the monitors were difficult to switch inputs if the input that was currently selected did not have an active signal. I had to keep trying to hit the menu button then quickly select the input selection before it dropped the menu saying no signal detected. The input selection should come up on the screen and stay for a reasonable amount of time regardless of whether a device is connected.Also the location on the back right means putting 2 monitors next to each makes one of them difficult to get to the menu buttons. The menu button should be located along the bottom or front. Other than the usability quirks these are awesome monitors and no visible light bleed in office environment and PQ is top notch. Updated: While disappointing that they don;t auto-detect, both monitors struggle to change inputs it is a fight every time, menu come up you hit a button and menu drops and when you hit input button it is back where it started, very frustrating monitor. Every few week sit si a fight to get the secondary monitor to work, does not matter what I hook these up to. Lowered rating to a 1 as I regret keeping these. When I can afford it I will look for alternatives.

Out of the box, this is not a good monitor for doing photo editing. Significant detail is lost in the shadows and highlights, which makes it very tricky to know if part of an image is truly over-exposed or under-exposed. In fact my 15 year old Sony monitor does a better job of showing detail in the far reaches of the histogram than this monitor does. There are various settings you can choose (standard, picture mode, low blue light, CAD, SRGB, movie, etc...). But no explanation for what they do. Very frustrating when what I wanted out of my "designer" monitor was simply to see my photos EXACTLY as they truly were. There is no manual that comes with the monitor packaging nor a reference to one you can download. Eventually I did google and find this. This provided detailed information for a range of monitors in these series...and was somewhat helpful but not completely. For "picture mode" it just said this was meant for viewing pictures... Eventually after some tinkering, it appeared that "SRGB Mode" was best and also you HAVE to change the "HDMI RGB PC Range" which otherwise by default clips the highlights and low lights. Once I corrected this, the image accuracy improved dramatically. It still isnt top notch, but I assume that it is about the best you can do for a monitor in this price range. My other qualms are somewhat minor. You can easily adjust the monitor height and angle easily enough, but the max-height it too short for optimal ergonamics and taller people. Im 511" and I had to use an additional monitor stand to get the middle of the screen to eye height. Being able to adjust the monitor 90 degrees is slick and the components mostly snap into place without screws which is nice. The menu system is decent, but in a dark room it can be tricky to see which light to initially press (super minor). The low-blue light mode is nice...basically you switch to it when doing a lot of web browsing to reduce eye strain (you do lose color accuracy, but for web browsing this doesnt matter). For a monitor like this, obviously you dont want to use VGA (although you can and many dual monitor users might be tempted to do this). I tried this and and the max resolution for VGA appears to be about half of DVI or HDMI, so choose you cable connection wisely.

This monitor is beautiful. It looks fantastic, and finally going to 1440p has been so worth it. Everything is crisp as hell. Some people say this isnt a good monitor for gaming, but Im loving it. I have only seen tearing in one game during a cut-scene that I think was pre-rendered or something as the rest of the game had none. No dead pixels. BUT. Like a bunch of others with this monitor, Im having display port issues. Basically every time you turn on the monitor or wake it up, theres like a 3% chance it wont detect a signal. Ive had this happen twice in 24 hours, and Ive had it not happen for like 3 weeks. In order to fix it you have to keep unplugging the monitor and plugging it back in, and keep trying to turn the monitor on again until it detects the signal (usually takes about 2 mintues). Im moving in a week and plan to exchange this for another. If not for this problem Id give this monitor 5 stars.

Amazing monitor! Im a colorphile and pixelphile, high pixel density and perfect color reproduction are what I look for in a monitor. I had bought the GW2765HT believing it was just a 1440p IPS monitor that had 100% coverage of the sRGB spectrum, but I was wrong, the monitor is also includes 10-bit color depth support. Albeit, its 8+2 and not true 10-bit, but it is still better than 8 bit by a long shot. I had the luxury of playing Alien: Isolation, the only game that I know of that supports 10-bit color depth, and was greeted with amazingly bright and deep colors, especially in the blacks, I had streamed game play and what they couldnt see on the stream I could. Of course, to take full advantage of a 10-bit desktop youd need a GPU that supports 10-bit depth on OpenGL and on the desktop, which is a feature only professional/enterprise-class GPUs have, but there are compelling offerings for such a GPU at $250, so its not that hard to obtain. I have experienced the issues with "No Signal Detected," and with my extensive analysis since February, I can conclude that the reason this happens is not because of the cable or ports, it is because of the BenQ Drivers and NVIDIA Drivers. In order to obtain 1 billion colors and 10-bit depth, the DisplayPort connection has to meet a high enough bandwidth connection state in order for the monitor to recognize the connection as stable enough, whether you use 10-bit or not it is still a driver-level limitation. When idling on the desktop, NVIDIA Drivers cut down bandwidth on all ports as a power-saving option on the kernel level, so when the monitor first connects to the port on the computer, it is not running at a high enough speed to detect a stable signal. There are 2 options to fix this: 1.) Reinstall or install a driver for NVIDIA GPUs. Whether its older, current, or a newer driver. The reason this helps is because when installing the Driver, the NVIDIA installer has to reinitialize the GPU cores, memory chips, VRM, etc. to recognize the new driver at the BIOS level. Thats why you hear the "Device Disconnected" jingle in Windows and shortly later the "Device Connected" jingle. When the GPU is reinitialized, it tests each available external video port at the highest possible bandwidth speed and power output to verify the integrity of each port and notify the user of port malfunction, this usually takes place with the motherboard making a beep or some other program popping up. These links to the video ports stay at the highest possible speeds for a time before the GPU detects the computers current power state and adjusts the power and links to the appropriate values (I.E., power-saving mode on idle) 2.) (READ THE PARAGRAPH DIRECTLY BELOW THIS BEFORE ATTEMPTING) Go into "Device Manager" in Windows, then to "Display Adapters" in the list, right-click on your GPU and click "Disable." Then after you hear the "Device Disconnected" jingle in Windows and the Device Manager has refreshed to show the disabled GPU, right-click it again and click "Enable." Make sure to connect your monitor immediately after you here the "Device Connected" jingle. When you disable the GPU, Windows notifies the GPU at the kernel-level to shut down and effectively cut power to the device, whichever comes first. It has the same effect that a driver install does when it is enabled at initializes. Keep in mind that when you do this, external video support WILL NOT be available on desktops, on a Laptop the CPU can take place of a GPU temporarily even without an iGPU because all the video ports and the display are interlinked with the CPU AND the discrete GPU. On a full-computer, pre-built or custom or any desktop, this usually isnt the case. I recommend you connect your Monitor to the VGA/DVI-D/HDMI port on the motherboard itself, because you wont be able to access Windows disabling the GPU. I am not responsible if you do not read this before attempting this fix. I hope these fixes helps anyone. It has proven effective 6/7 times that I have tried this in the past 5-6 months.

I have a BenQ GW2765 and I love it. Thought this one would be perfect. Got it and the display cuts in and out and a popping sound comes from the back of the display. Returned it, got a second one. Popping noises and display cutting in and out. Do Not Buy.

Received the monitor today. I bought it primarily because I want more resolution than 1920x1080. Unfortunately, no matter how I connect it to my MacBook Air (2013) I only get 1920x1080. (I have tried HDMI, VGA, and DVI - all using mini-displayport dongles.) A bit of research and it seems that my only option for full resolution is to use a mini-displayport to displayport cable. Of course this is the one cable not included with the monitor. (It would be nice if the user manual or the Amazon description had let me know Id need this cable so I could have ordered it at the same time as the monitor. They print the Mac logo on their box, but I wouldnt exactly say this is a Mac friendly device so far.) Once I get the new cable and (hopefully) experience the resolution I paid for, Ill update this review. At 1080p, the color is fantastic, text is crisp and readable, and everything was pretty much good to go out of the box. The Vesa mount worked fine for me. My favorite feature is the USB port on that back that I am using to connect my third monitor (a ViewSonic) using the GoFanco connector. All the cords are now managed behind the monitors, and I have my USB port back! I think Im gonna be happy with this monitor. Ill keep you updated.

Im a photographer and photo editor, but unfortunately didnt have a wide screen monitor till now. So this is my 1st one. Under 500$ price I think this monitor is great option for photographers and photo editors. I did a lot of research before buying this. There were some other great ones but more expensive. So with this price this model is great. Its supporting great sRGB which I need most at this moment. But cant say the same about the RGB (not very accurate). Also I havent calibrated yet, not sure how to do it in best way. But anyway, great progress after small screens. Im happy with this purchase. Hope will not update this review after some months and downgrade it. Currently working fine! wish it also has usb ports...

I got a new computer so it was time to upgrade from a lovely 24 inch ViewSonic 1080p monitor to a 1440p monitor. My ViewSonic was purchased from Amazon in August 2011, for $209 and it still works great; keeping it to use with the old PC, also new in 2011. I was planning on getting another ViewSonic, but after extensive research the cost of a comparable ViewSonic compared with this BenQ GW2765HT was not what I wanted to spend. The online and Amazon reviews of this BenQ were very good, and for $299 this was the lowest price for a brand name 27 inch 1440p monitor with IPS. Of course this monitor does not have all the super duper features of monitors costing hundreds more, but I am very happy with it. 1440p at 27 inches is just perfect and wonderful for video & photo editing, viewing multiple documents, web surfing, or watching movies. As of this review I have only had it for a week, but there have been no issues. It is unfortunate that some Amazon reviewers have had problems with this or other BenQ monitors, but this model has been in production for a few years (mine was made in August 2017) so maybe some of the manufacturing defects have been improved. I did buy the Square Trade protection plan just in case. If money were no object I probably would have purchased a top end ViewSonic, but so far BenQ is the bees knees. The control buttons being on the right rear is fine with me and I was able to quickly set the color and other adjustments to look great with my Nvidia graphics card and the Nvidia adjustment software. I have it connected using a display port cable. I have no intention of using the monitor speakers, I have some decent computer speakers.The one great improvement of this monitor as compared to my old ViewSonic is the IPS technology. With my ViewSonic or any older LCD monitor you really need to be looking straight at it for the colors and brightness to be correct. With these new IPS monitors you can view your screen many degrees off angle and the colors and brightness dont shift.
