For Projectors, Only 3 Projection Technologys in the world:  DLP;  LCD/3LCD;  LCoS. 

I've already writen a page explain all the details, please find in this link:

And Now, we main Focus in DLP Projectors:

First, About the Resolution:
0.2" FWVGA 854x480
0.3" 720P 1280x720
0.45" WXGA 1280x800
0.47" 1080P 1920x1080
0.65" 4K UHD 3840x2160
NEWEST TECHNOLOGY:
0.33" 1080P', 1920x1080' XGIMI Z6; JmGO G7/N7L; ...
Dual 0.47" 4K' UHD, 3840x2160' XGIMI Lune4K; JmGO X3; ...
Second, About the Brightness: 
50 ANSI Lumens 0.2"DMD / 854x480 TOUMEI C800, ...
100 ANSI Lumens 0.2"DMD / 854x480 AODIN D02; ...
150 ANSI Lumens 0.2"DMD / 854x480 CACACOL T13; ICANZUO P10; ICANZUO P10-II
720P:
250~500 ANSI Lumens 0.3"DMD / 720P XGIMI CC-Aurora; CACACOL T8; JmGO P2; XGIMI Z4-Air; ...
700 ANSI Lumens 0.45"DMD / WXGA XGIMI Z4-Aurora
NEWEST 1080P:
900 ANSI Lumens 0.47"DMD / 1080P XGIMI H1; JmGO J6S; ...
1000~1100 ANSI Lumens 0.47"DMD / 1080P XGIMI H1-Aurora; XGIMI H1S; ...
1350 ANSI Lumens 0.47"DMD / 1080P XGIMI H2; JmGO J7/N7; ...
1500 ANSI Lumens 0.47"DMD / 1080P XGIMI H2-Aurora
1500 ANSI Lumens Dual 0.47"DMD / 4K UHD JmGO X3

Those 1500 ANSI Lumens, already enough for Home Use.

If ask More High Brightness, then Only way is use Laser Light. 
NICHIA (JAPAN) ... ...
Appotronics ALPD3.0 Laser Technology 0.47"DMD; 1080p Full HD JmGO SA
Appotronics ALPD3.0 Laser Technology Dual 0.47"DMD; 4K UHD JmGO S3
CoreTronic Laser/LED Technology 0.47"DMD; 1080p Full HD XGIMI Lune, A1, A1-Pro
CoreTronic Laser/LED Technology Dual 0.47"DMD; 4K UHD XGIMI Lune4K; XGIMI T1

 These several Laser Projectors are wonderful, and with Super Short Focus. Perfect enough but only Expensive much. 

 --- --- --- ---

Then, If still ask more Cheap projectors, then need back to choose LCD Projectors:

---  640x480 ...we no do...
--- 800x600 ...we no do...
SD300 720p, 1280x800 2800 Lumens; HDMI; Without Android
W2019 1080p, 1920x1080 3000 Lumens; HDMI; Without Android
CRE X2001 1080p, 1920x1080 3000 Lumens; HDMI; With/Without Android System

 

Third, LCD Not so well, then we choose 3LCD Projectors:

3LCD are all base on EPSON/SONY Technology
CRE X8000  1920x1200
XGIMI LINGTANK D1 1920x1200
3LCD is still Perfect too. Only matter is the size will more big. and the Heat dissipation is a matter, need more fans. Cause the Noise will more noise too.  But for Business not a matter.
