Applications: what the Acer HL6820G is ideal for

Home cinema even in daylight

With 4,000 ANSI lumens, the HL6820G delivers a bright, clearly visible 4K image even in rooms with ambient light – with the blinds closed or evening lighting on. For optimal results, we recommend an ALR screen (ambient light rejecting), which absorbs stray light and brings the dynamic contrast of 3.5 million:1 into its own. HDR content from streaming platforms and 4K Ultra HD Blu-ray benefits directly.

Gaming sessions

1 ms input lag at FHD makes the HL6820G a compelling choice for PS5 and Xbox Series X – responsive display on a 100" screen and more. VRR via HDMI 2.1 dynamically adapts the frame rate to the console's output and prevents screen tearing in demanding scenes. With a 240 Hz refresh rate (FHD), fast movements run smoothly. For maximum performance, we recommend physically correct placement in front of the screen – digital keystone correction increases latency.

Football and sports

4,000 ANSI lumens ensure a bright image even in a living room with the lights on. Acer Football Mode automatically adjusts brightness, saturation and sharpness – grass looks rich green, while skin tones remain natural. The integrated 10 W speaker provides basic sound for spontaneous match nights; if you want a stadium atmosphere, connect a soundbar via the 3.5 mm jack output.

Picture quality

The Acer HL6820G relies on DLP technology with a 0.47" DMD chip and displays 3,840 × 2,160 pixels in 4K UHD. The brightness of 4,000 ANSI lumens delivers a bright image even on large screens; the dynamic contrast of 3.5 million:1 ensures a three-dimensional sense of depth in dark scenes. The colour space is specified to Rec. 709 and Rec. 2020 (compatible) – HDR signals from streaming services and Ultra HD Blu-ray are processed and reproduced within the projector's available contrast range.

Gaming performance

1 ms input lag in gaming mode (FHD, according to the manufacturer) places the HL6820G among the top gaming projectors. VRR via HDMI 2.1 compensates for fluctuating frame rates from a console or PC and prevents visible tearing. A 240 Hz refresh rate (FHD) displays fast game scenes and camera pans smoothly. For competitive gaming: choose physically correct placement in front of the screen – digital keystone correction adds measurable latency.

Sound

The integrated 10 W mono speaker provides basic sound for spontaneous film and gaming nights. For room-filling sound, use the 3.5 mm jack output to add a soundbar or a home cinema system.

Smart features & streaming

The HL6820G is designed for use with external streaming players. Apple TV 4K, Amazon Fire TV or Google TV Streamer can be connected directly via the two HDMI 2.1 ports – giving you instant access to streaming apps such as Netflix, Disney+ and more. The second HDMI port remains free for a console or Blu-ray player.

Installation, projection & in the box

According to the manufacturer, this projector supports screen sizes from 26 to 303 inches at a throw distance of 1.0 to 8.0 m.

The calculated throw distances are based on the manufacturer's throw ratio and are intended as guide values.

The HL6820G supports front, rear and ceiling mounting as well as 360° operation – the device works in any position, including projection onto the floor, the ceiling or in portrait format for special installations. Automatic keystone correction (±25° vertical and horizontal) makes quick setup easy. The 1.3× optical zoom and a fixed offset of 110% allow flexible positioning: the image sits automatically 10% above the centre of the lens – handy when placed on a table directly in front of the screen.

The projector measures 322 × 225 × 109.7 mm and weighs 3.3 kg.

Connections:

• 2× HDMI 2.1 – supports VRR for gaming; both ports can be used simultaneously for a console and a streaming player
• 1× USB-A – integrated media player for local files (incl. MPEG-4, H.264, H.265); DC output (5 W) for Fire TV Stick and comparable streaming sticks. Please refer to the manual for the complete list of formats and codecs.
• 3.5 mm jack – audio output for headphones or external speakers

In the box: Power cable (IEC 320 C13), IR remote control incl. batteries, HDMI cable (1.80 m), carrying bag, PIN security card, quick start guide.

Light source & operation

The HL6820G's laser light source is maintenance-free and lasts 20,000 hours in Normal mode – with a daily 3-hour film night, that's around 18 years. In Eco mode with 3,200 ANSI lumens, service life extends to 30,000 hours.

Instant Pack lets you unplug the power cable immediately after switching off – the laser light source is ready straight away and needs no cool-down phase. Power consumption: 195 W (Normal), 120 W (Eco), 0.5 W (standby).

In Eco mode, the HL6820G runs at 29 dB – pleasantly quiet and barely noticeable even in quiet film scenes.
