The Philips Monroe LC6131 has a maximum resolution of SVGA (800x600). That's 53% less resolution than the most frequently found native projector resolution of WXGA (1280x800). The worst resolution of all multimedia projectors of a comparable spec and age to the Monroe LC6131 is nHD (640x360) and the best is DCI 4K (4096 x 2160).
We compared all the other projectors that have a resolution of SVGA (800x600) to this data projector and we think a higher Kagoo Rating™ projector such as the P1173 (£229.99), and the X1173 (£265.98) both from Acer or the Epson PowerLite Home Cinema 500 (£214.58) are also worth considering.
If the resolution of this projector is too low for you then you might want to also look at the Aiptek MobileCinema Q20 (540p (960x540 and higher rated) and higher rated), the Epson V11H445320 (540p (960x540 and higher rated) and higher rated), or the NEC NP-PX800 (XGA (1024x768 and higher rated) and higher rated).
