GIGABYTE M28U EK 28" LED 4K Ultra HD Gaming Monitor - 3840 x 2160(4K Ultra HD), 144Hz, 1ms, FreeSync Premium Pro, DisplayHDR 400, High Dynamic Range (HDR) 1500, High Dynamic Range (HDR) 400, HDMI 2.1

A big and beautiful monitor. Great picture quality, good colour, refresh rate as advertised. Speaker quality is pretty awful but you’re not buying this monitor for the speakers really.

Really good monitor for the price. Easy to install straight out of the box. I mainly use this for console gaming specifically ps5 and it’s able to run 1440p 120hz perfectly fine. The colours look very vibrant and sharp. Bezels are really thin.I also use this for work and it still looks amazing. If you’re interested in buying a good quality monitor that isn’t too expensive I recommend getting the M27q

I think the M28U is probably the best PC monitor you're going to get for this price. Its also one of the smallest 4K monitors available, which is great if you don't want a huge widescreen monitor.Overall, the image quality is pretty good, and the 144hz refresh rate is brilliant when gaming.The "Arm Edition" is actually really convenient for attaching to a desk, no need to drill holes in your wall to mount it, it simply clams onto the "back" of the desk.The "arm" is very stable, and creates free space under the monitor where the stand would normally be.The "Arm Edition" is also very easily adjustable when mounted.The image quality could be slightly better, it's not the best out there (you get what you pay for)The HDR 400 isn't the best, but it's "OK"The brightness is adequate but not overly impressive.Overall I think the M28U is a great all-rounder for the price, and it's excellent for gaming.I highly recommend the "Arm Edition" if you have somewhere to mount it to, I'm impressed by how stable it is.

It has crisp quality, sufficient ports, and good viewing angles - whether you use it for work or gaming.Got it on sale and it's worth the price.

First, the negative part: it took almost 2 months to arrive in Ireland. That's it. Everything else is positive. Excellent image quality. I'm not a big gamer nor very demanding, but I also use it for work (programmer), and the quality is good. It doesn't strain the eyes. I used to have two 27” 1080p screens, and I wouldn't go back. The size is perfect for having multiple windows open without the disadvantage of the separation between screens. I haven't seen any dead pixels or light leaks so far. If you use it as an external monitor for a laptop, I recommend buying a Thunderbolt 3 or 4 USB-C cable to charge the laptop without a charging cable (up to 100W). In my case, with a MacBook Pro M2, it charges, but 100W is not enough, so by the end of the day, the battery is halfway, but it still works for me. If you are looking for a versatile monitor, this is a very good option.

Edited: was 3 stars at first as was hoping that I had wrong settings, but no. This is not a good monitor, and seller was terrible with return. I would never buy this again, simply because it was a nightmare to return.Seller and online review sites say this is g-sync compatible, it's not. I get crazy flickering with it on, and constant low-level flickering when off. Kept thinking I saw something in corner of eye, and I confirmed it later on. It might be just fine with freesync/AMD GPUs, but I can confirm it's not if you don't have this.VA panels are meant to have bad viewing angles, and this is curved. But I don't think it is that bad at all. Reviews on youtube say great colour spectrum coverage, but misses some greens. I think the greens are fine, and the black uniformity is great! No ghosting, but room lights off, with a black screen shoes a lot of bleeding. This can vary with models.Glare seems to be a major issue with this. I swear I saw on video reviews that it's meant have an anti-glare panel coating or something, but I am asking customer support if is true. Either way, I cannot have any natural light, and have to have as many lights turned off as possible. Bright scenes it's not as bad, but dark scenes are hard to make out anything over the damn glare.As for controls and functionality, I hate the control button so much. I have no idea what most of the settings do, and Gigabyte offers zero clues in the instruction manual. Which comprises of a couple pages telling you how to use a screwdriver for the stand, as if that is big brain stuff. It has a single crosshairs reticle overlay, which is less than my old monitor, and you cannot adjust it up or down. It can't shift by itself off-centre like my old one, but I also cannot adjust for distance like my old one. Worse is the power button. It doesn't have one! You have to click the joystick button on the side and the swipe down to power off. And if your PC turns off before you have turned off your monitor, you will have to turn the PC back on so you can turn off the monitor. Otherwise it will go on standby. I hate having to do a stupid ritual every time I shut down.Is this the cheapest? No. But it came up as the best monitor that doesn't have a local dimming feature, and it is probably decent for AMD GPUs. Main negatives are, power button, limited Crosshair overlay, and bad glare.If you want a 4k true G-sync compatible monitor, and don't mind local dimming, go Samsung G7. I've got a G7 and it has over 1000 local dimming points, over the industry standard 5-10, which is insane and gets past 80% of the negatives of local dimming. Bit costly, but it's the best for G-sync 4k.
