ASM_GBHS Posted July 28, 2015 Posted July 28, 2015 Hello All, Recently we tendered for a batch of 4k screens in replacement for the awful projectors that we had. Currently we are having some interesting technical difficulties that-isn't really related to the thread but figured I'd give some backstory. In a stretch to test the new 4k screens and see if we can replicate the issues we have been having, I've quickly built up a machine that has a dedicated graphics card (AMD Radeon HD 5450) for some reason it appears to be only allowing me to select the 1080p option, where as all other machines on the same cable and port have showcased a 4k option bar one which I believe might've been a chipset related issue. All the drivers are up to date and I've just finished doing a Windows Update in case something there might help. Any ideas? Thanks
featured_spectre Posted July 28, 2015 Posted July 28, 2015 I could be wrong but if I remember rightly, the 5450 wont support 4k. 1
ICTDirect_Dave Posted July 28, 2015 Posted July 28, 2015 I'm not sure you'll be able to get 4K out of a HD5450 There DVI port wont do it, nor will the VGA and the HDMI port is likely to be at best version 1.2 and probably wont go beyond 1080p. It's an old card unfortunately and you probably will only be able to get 2560 × 1600 out of it using a dual link DVI cable. 1
ASM_GBHS Posted July 28, 2015 Author Posted July 28, 2015 (edited) I could be wrong but if I remember rightly, the 5450 wont support 4k. That might explain it I suppose, I did some research and some people have said it does but I suppose you can't believe everything you read. If this is the case then it would be a great help and would solve my issue! lol. Okay this saves me a lot of time, thank you! Edited July 28, 2015 by ASM_GBHS
BrettH Posted September 8, 2015 Posted September 8, 2015 I could be wrong but if I remember rightly, the 5450 wont support 4k. You are correct! Here are the specs for that card (Click the Specs tab). Integrated dual-link DVI output with HDCP11 Max resolution: 2560x1600 Integrated DisplayPort output Max resolution: 2560x1600 HDMI® (With 3D, Deep Color and x.v.Color™) Max resolution: 1920x1200 Integrated VGA output Max resolution: 2048x1536 4K refers to one of two high definition resolutions: 3840 x 2160 pixels or 4096 x 2160 pixels.
