Acer H6521BD Home Cinema Projector (WUXGA Resolution, 3500 Lumens, 10000:1 Contrast Ratio)

TL;DR - Amazing home cinema and gaming projector for £350, with a few drawbacks which are expected for this price rangeUpgraded from a hand-me-down 10 year old ~2000lm optoma which was not even 720p.Running this on a Luxburg 100-Inch 16:9 221 x 125 cm matte white pull down screen, and a very cheap 120w snowdon sound bar (I live in a terrace - don't want to annoy the neighbours!).Projector is ceiling mounted ~3m away from screen using a generic mount, and has a 10m kettle lead and 10m hdmi lead going to a gaming PC with GTX 1070 and I7 7700kI use this for films, TV, gamingFirst off - the bad:- Obviously speakers (but who cares - you're hooking this up to a sound system - get a cheap soundbar for £30 and you're set!)- No horizontal keystone for off-center mounts (easily avoidable by mounting toward the center of your screen)- Low input lag mode only works with no digital zoom or keystone adjustment (though this can be avoided by placing the projector the correct distance and height from the screen)- I believe analogue zoom is only 1.1x, not 1.3x like some others - however 3m throw distance for 100" seems fine, and it's not even at full analogue zoom- Fairly noisy, during quiet scenes you can notice it, however it's no noisier than my old one. Typical of projectors and suggest not being turned off by this fact.- When running 15m VGA cable alongside a power cable - vertical scanlines appear. This seems to be less a fault of the projector and more a fault of analogue signal- Samsung TV (ue43j5500) remote conflicts with receiver of projector. Turning volume up on TV changes vertical keystone. Not a huge issue most of the time as typically you have one or the other turned on.- Can seem a little jittery when playing games which depend on high refresh rates (projector is 60hz) such as geometry dash.- Native res appears to be 1920x1200, not 1920x1080 - however setting it to 1080p appears to have no negative affect on the picture quality. You can even set the res to 2560x1440 however the picture is not very clear and there are a lot of 'jaggies'.- Only 60hz refresh rateThe good:- Price. For £350 this is an amazing price for such a quality piece of kit- Incredibly bright picture. I can use this during the day and it is actually viable (though not ideal). I can even have some small lamps on during dusk and it is still easy to see what's going on. Even better in a pitch black room- Input lag is minimal (but just noticable in high octane games) even without low input lag mode turned on- With low input lag mode on, I can honestly barely tell the difference in input lag between the projector and my 144hz gaming monitor- Pre-set modes are great. Mostly use 'Game Bright' (which turns on low input lag mode) and 'Movie'. Sometimes I use game bright for dark movies and it looks great.- Remote doesn't need to be pointing directly at projector, is easy to understand and use, and seems quite well built. Buttons are tactile and clicky. Makes settings very simple to change.- Build quality of the projector is great for the money. The lens adjustment is solid and zoom is also solid. One issue I had with older projectors is whenever I put the lens cap on it would shift the lens and go out of focus for the next time I used it. The design on this means the lens cap goes on without affecting lens shift - so I never have to bother re-adjusting to make it sharp again.- Has some neat features to avoid burning your eyes out when looking into the lamp, though I find these detract from image quality so don't bother using them- I am no expect on colours / calibration - but after watching a few movies, a few grand tour episodes, and a GoT episode, playing multiple games (risk of rain 2, destiny 2, gta 5, rocket league) I am extremely pleased with the picture quality, colours, brightness - and pure diversity of this thing.

The first thing to say about this is how substantial it is. It's a lot heftier than I was expecting. Looking through the instructions and the menu options there are a tremendous amount of settings and features that are going to take some time to work through to find my personal preference.Setup is easy, plug in the power cable, plug in the source and switch on. The most complicated thing you'll need to do is work out the optimal distance between the projector and your wall or screen and then turn the focus dial.First impressions, the fan is quite loud, which may not suit everyone, particularly if you are going to be sat near the projector itself. If you're not near it, then it's not so loud to be an issue, particularly in a large room.There is a set of buttons on the unit as well as a remote control. As far as I can tell so far, you can perform every available function with either, so none of this having to either trek to the machine or search for the remote just to perform one or two rare functions.The picture is very impressive. Clear, sharp, crisp with lots of detail and colour, even when projected on to a heavily patterned white wallpaper.The picture even projects well in a quite bright room, although as you'd expect it does even better in lower light conditions and projecting away from windows on a bright summers day.This does give one of the units down sides however. The power of the bulb creates a tremendous amount of heat, so not only do you need to keep the unit very well ventilated, but you also will notice an increase in room temperature over time if you're in a smaller well insulated room, so it's probably not ideal for bedrooms.The biggest issue I can see is the sound quality, it's not great. It has plenty of volume, but it's very tinny, has no depth of sound and means you need the volume up fairly high to hear clearly, but the sound then travels all around the house. Which brings me to the second main issue, the connectors...The quick guide and the instructions show very different connectors than those available on the unit. I can only assume that they are for multiple versions of the device, but the unit I received had the following:1 HDMI port1 DC 5V out (USB) port for powering things like streaming sticks1 VGA in1 Video in1 Audio In (3.5mm)Whilst that probably covers most things, it does mean that for home use, you'd need to keep swapping HDMI cables if you wanted to use a Streaming device, DVD player and a freeview digibox.Whilst the unit overall seems very good, the lack of connectors and the poor sound (along with no audio out option to feed it through a stereo of any kind) makes this particular model seem less suited to home use and more suited for presentations or classroom use. If you're wanting it for a home entertainment system I'd suggest looking at an Acer model with a few more connectors.

Resolution is okay, strength as well,but the color quality is really pure.Whites comes across super bright, but colors has no real saturation,especially green, even the strongest one is grayish and dark.For this price you can find a home cinema projector with a bit less native resolution,but superb color quality. End of the day, what you see is the nice colors...I've tried various color settings, nothing helped,I suspect the actual hardware has a low end display inside.
